In Minsk fitness clubs, not only adults, but also children from one and a half years old are engaged. Preschoolers dance, swim in the pool, and upon reaching the age of 9-10, they begin to do exercises with weights, forming muscles. The Village Belarus found out whether it is worth giving children to barbell squats and the dangers of heavy loads at an early age.

Boys start earlier than girls

The minimum age for lifting the barbell is set by the Ministry of Sports and Tourism of the Republic of Belarus and the Ministry of Health of the Republic of Belarus in the resolution of January 16, 2017 No. 2/6 “On establishing the recommended minimum age for practicing sports”. According to him, boys can do weightlifting from the age of nine, girls from thirteen.

It has been proven that in pre-adolescence, due to the effective use of the nervous system, strength is gained well, but muscles are poorly gained. According to the WHO, the earliest age to benefit from strength training is ten years. However, the child must exercise under the supervision of a coach and a sports doctor.

You need to do physical exercises in any case, this is life. Of course, at the age of nine, children will not be allowed to lift weights. They swim in the pool once a week, perform game exercises, work out with small dumbbells, and work out the technique of lifting the barbell with a stick. Strengthen muscles, ligaments, knee, ankle, shoulder, chest. Serious studies begin when puberty ends. As a rule, this is at the age of 14, but here it all depends on the characteristics of the organism.

We are preparing a reserve for national teams. But I think our main task is the health of children. We must prepare them not only physically, but also mentally, morally, psychologically, so that they are not afraid of anything, they are strong and courageous.

We do not have a goal to give large loads. Children now are rather weak compared to what they were 30 years ago. They come at first glance strong, with certificates for weightlifting. And then at the medical examination they are eliminated with scoliosis and vision.

We also have girls, about a dozen out of about a hundred students, but it's hard to work with them. Although, I think that weightlifting is better for a woman than wearing sleepers or working in a foundry.

There is no need to be afraid of weightlifting, it is a very interesting, versatile sport. Physical education also cripples, if you give the wrong load. And sports don't hurt. And in children's sports there are injuries, especially in game, contact sports. Look at football players, hockey players, talk to rhythmic gymnastics coaches, how many injuries they have - and their backs, and feet, and knees. But no one writes about it. There is no need to rush in weightlifting. We need to work slowly, and in conjunction with the coach-athlete.

Of course, injury is inevitable. At the age of 61, my ankles also start to hurt, old injuries come out. Therefore, we are practicing the skills of working with shells to automatism. Safety is in the first place for both children and workers.

Any professional sport is harmful to health. The border between benefit and harm lies where training begins twice a day. "Physical education for health" is when you exercise 3-4 times a week. And here 7-8 workouts plus regular competitions.

No sports doctor eliminates the harm from the consequences of professional sports. It only helps to endure stress longer, plus it contributes to the selection of the most genetically predisposed children.

If you conduct classes gradually and slowly, then you will not become an outstanding athlete. Professional sport involves work close to the limit of human capabilities, and squeezing out all the reserves.

No, it is necessary to engage in some kind of activity. But it is not necessary to turn it into a professional sport. Recruitment in various sports occurs at different ages. Usually admission to special classes is carried out in the seventh or eighth grade, and then the child decides whether he wants to study “for himself” or become a professional.

I treat women's weightlifting with great prejudice and would not give my child to such a section. Lifting weights is not very suitable for a woman. In weightlifting, girls who look like boys can be realized.

Before choosing weightlifting as a wellness activity, you need to think very seriously. After all, these are different sports: just strength exercises, health-improving, and weightlifting. It is possible and necessary to use weightlifting elements in fitness. But doing weightlifting ... This is always a decision that everyone chooses for themselves, and justifies why they need it.

My son has been a powerlifter for five years. He started at the age of 12, in the 11th grade he decided to focus on his studies and warned the coach that he would do it “for himself”, and not work for the result, that is, without competition. The coach was upset and both lost interest in training based on the logic: why bother now?

The university had the opportunity to study, but there was no time, energy - and motivation, I guess. However, after coming home for the holidays, my red-bearded Viking started going to the gym again. And I thought: why am I chilling on the site for three years, and didn’t talk about powerlifting “based on personal experience”? Everything went through my maternal heart.

background

At 12, my son was a typical nerd. An excellent student, with a bunch of complexes - thanks to the school environment. Unconfident. Preferring books, TV and a game console to live communication. At school, there was no communication according to interests (and according to the level of intelligence) for him.

At first we tried to send him to one section, then to another. He was engaged in shooting, but without much enthusiasm. He did not have a trusting relationship with the coach - and this is the key to success. Well, then his virtual life completely corrupted.

Psychological blackmail went into action: until you start doing something (God, at least something, at least embroider with a cross!) we won’t buy a computer. A colleague went to the sports complex and recommended me her coach, who leads the powerlifting section. She knew the character of my child and was sure that they would develop a relationship with this coach.

Half from under the stick, half from interest - the son went to record. He was 12 years old, the coach said it was too early. But since the boy was tall, strong, he took him. The coach himself is the champion of Russia among veterans. Mostly adults go to him, but there were also schoolchildren. And there were girls. So my offspring finally filled the vacuum in communication.

But more to the point

The first years of classes were held without equipment. These were general strengthening exercises on power simulators, no one allowed him to lift heavy weights. Powerlifting is triathlon. Bench press, deadlift and squat. To say that it is very spectacular - no. Not figure skating.

Worked out three times a week. Left at 5:00 pm, arrived at 8:00 pm. Passed only in case of severe malaise. The regime—especially in high school—has been turned on its head. Daytime sleep and nocturnal insomnia. Be sure to sleep before training. In general, a lunatic. His studies did not affect his studies. Especially for immunity, too, but he was sick only during the holidays.

As he now admits, he did not work out of special love for the hardware. The attitude of the coach - time. I didn't want to let him down and disappoint him. Discipline two. Ambition three. Beautiful body - four. Well, about the body, I added from myself. I think he doesn't care. In general, he is such a ... philosopher. Self-confidence - five. Sufficient amount.

Core fear: weightlifting is injuries, it is a load on the spine, these are health problems - not now, then later.

We haven't had a single serious injury in five years. Shoulder somehow pulled, it was the case. Poorly warmed up before training. It was then that he was in the hall and recommended an ointment Nicoflex. And in general - not a single bruise. Only from equipment. For those who are interested, google what it is.

It all depends on a competent coach - so that he sees the condition of the athlete and does not give an excessive load. Correctly calculated his strength. The rest depends on the athlete: how much he controls his body, how accurately he coordinates movements, how technically he performs the exercise.

Next question: how expensive is powerlifting? Inexpensive. We didn’t buy weights, we worked out in sneakers, we just chose - in which it is more convenient for him to do exercises. Wrestling for the competition was issued by a sports organization. They bought overalls and a T-shirt, the overalls were new - 5 thousand rubles (at the prices of previous years), the T-shirt was used, got almost for nothing. Yes, also leggings for competitions and garbage bags for 60 liters - to pull on the equipment. Bandages, wristlets and a belt were also given out from the organization.

Sports nutrition. After training, I tried to feed him protein foods so that the “meat would grow”. But where else could he grow when we were already flying out of all the trousers and jeans like a bullet and could not buy anything on his swollen buttocks and hips? He didn't want to take anything on purpose either. In general, we had natural meat. Own.

The figure began to take shape and sculpt at the end of the first year of training. Press cubes. Triceps-biceps. Well, everything else.

I, the naive Gray Sheika, thought that "let her do it for herself, for her health, for her figure." But the boy needed ranks and CCM.

In general, we do not have one coach - there are three of them, and each has its own group. Here they compete with each other. The son began to show the first results at city competitions. The first medals, the first cash prizes.

He believed in himself, and the coach made a bet on him. After all, every coach wants to grow a champion. The question is: at what cost is he prepared to achieve this?

All serious competitions were away. This is usually a tiring road, not a very cozy haven and fast food. At night, the coach snored - so the son did not get enough sleep. At competitions, he showed good results, but they were worse than those in the gym. Stress, anxiety, fatigue affected. Here it was important to support at every stage, not to let them be disappointed in themselves.

Our greatest achievement is the third place in the championship of Russia in our weight category.

My son has the first adult category, according to the standards of last year, he would have taken the CCM, he really wanted to, but the standards were increased by 5 kg just before these competitions. However, the first adult category at the age of 16 is very good.

His highest documented results:

Deadlift: 225 kg

Bench press: 122.5

Squat: 225 kg

There are many contraindications for this sport. I won't even list them. The section is taken only with a certificate from a doctor. One boy showed good results, but was forced to leave weightlifting - progressive myopia.

To recommend or not to recommend is a very personal matter. I think that powerlifting is already in my son’s blood and he will do it. "For myself". We didn't have much choice in the city. Although the best sports in terms of forming the right character traits are team sports. Volleyball basketball. But they weren't interested. He is such an individualist. Weightlifting contributes to the formation of such negative qualities as stubbornness, incredulity. All this is. Well, there are quite a few positive ones - perseverance, diligence, endurance. I'm not going to judge objectively. And subjectively - the highest score. Still, five years of life, three hours, three times a week ... this is an indicator.

This sport is based on lifting any weights. Most often they are a kettlebell or a barbell. The division into categories occurs according to the sex and weight of the athlete. Professionally, he began to develop in the twentieth century, but is still popular among both women and men.

It is well known that weightlifting is useful in that it contributes to the effective maintenance of the overall tone of the body. Weightlifters-bodybuilders, eating and exercising properly, are healthy and hardy, have a beautiful muscular relief. But in addition, there are many concerns about how weightlifting affects health. The opportunity to get arthritis, arthrosis, intervertebral hernia, a “ripped” back, a worn out heart in the course of recovery does not appeal. Let's deal with whether the impact on the health of weightlifting is really so serious and negative.

Weightlifting for children: benefit or harm

Strength training involves lifting heavy weights. Therefore, children under the age of seven are not recommended to be sent to classes. Upon reaching this age, if the child is already independent, able to listen to the instructions of the coach, adhere to safety rules, classes may well be an excellent option. If a child is interested in this sport, it will be useful for him to know how weightlifting affects muscle growth. Let up to 12-14 years old, his main task will be to build muscle mass.

Does weightlifting affect height? This question is often asked by children's trainers, since there is such a point of view: aerobic power loads contribute to the cessation of growth. According to both recent research and the experience of athletes, training with adequate load, begun at the age of eight years, does not adversely affect growth, does not slow it down. The claim that weightlifting affects height has been debunked.

Harm from classes can be only in two cases: incorrect technique for performing exercises or the presence of contraindications. They are any problems with the back, high blood pressure, diseases of the cardiovascular system, visual impairment. Even if your child does not have any of these problems, we recommend that you always consult a doctor before starting classes.

And a competent trainer should monitor the correctness of the exercises. It is very important not to allow excessive stress on the fragile bones, muscles or ligaments of children. It is better to perform a large number of exercises with a small barbell or even with your own weight.

The benefits of proper strength training are many. Here are just the main ones:

• Increased stamina;
• Building muscle, increasing their strength;
• Strengthening bones, joints, ligaments;
• Acceleration of metabolism;
• Maintaining a stable normal level of weight, pressure, cholesterol;
• Raising self-esteem, dignity.

Thus, we can conclude that competent weightlifting with a good coach will have a positive effect on the well-being and condition of even the youngest athlete.

Benefits of weightlifting

We have analyzed the pros and cons of doing this sport for children. Now we note how weightlifting is useful for adults:

1. Slimming, normalization of weight. Regular training can not only form a beautiful body externally, but also contribute to this from the inside. It has been proven that weightlifting effectively speeds up the metabolism. Of course, training burns a lot of calories, preventing fat from being deposited in problem areas.
2. Fight stress. Training can relieve stress, eliminate depression, improve mood, help switch to another wave after a busy day. Recent studies show that exercising at least twice a week reduces the level of cortisol - the “stress hormone” - by 2-3 times!
3. Improving the quality of sleep. Strength training is able to relieve nervous tension well, as a result - to normalize sleep.
4. Prevention of problems with the back and lumbar region. Training strengthens the core muscles, which in turn support the spine, form posture. The stronger they are, the less likely the occurrence of various stagnant processes that adversely affect health.
5. Strengthening the cardiovascular system. Training can lower blood pressure, speed up blood circulation and increase endurance in general.
6. Improving brain function and cognitive functions. One of the newest studies has yielded some very impressive results. It turned out that strength training significantly affects associative memory and organizational functions. And both of these processes are very sensitive to aging and neurodegeneration: the degeneration of neurons that occurs, for example, at the onset of Alzheimer's disease.

Based on this, we conclude: the benefits of weightlifting for men and women are very great. The main thing is to competently, wisely approach training, not forgetting about safety precautions.

Harm of weightlifting

It should be noted those situations when weightlifting is really harmful to health. This happens in the following cases:

1. Classes in the presence of contraindications.

Before starting training, it is necessary to consult a doctor even if you do not find any of the following in yourself. Diseases in which classes are prohibited or recommended under the supervision of a medical specialist:

• any impairment of the organs of vision;
• diseases of the cardiovascular system;
• high or low blood pressure;
• violations of physical development;
• brain injury;
• diseases of the nervous system, mental disorders;
• chronic diseases such as epilepsy;
• disorders of the skeletal system, in particular - injuries or pain in the back or lower back;
• for girls and for women - restrictions in classes depending on the phase of the menstrual cycle.

2. Too much inadequate load without a preliminary warm-up.

And these are all scientifically proven aspects of when and why training can be harmful.

We hope that our article was useful for you! We wish you success and new achievements!

Preparation of a young weightlifter Dvorkin Leonid Samoylovich

2.1. The development of the body of children and adolescents

Children 7-10 years old came to the weightlifting section. A reader who is not familiar with modern ideas about the training methodology in this sport will be sure that the coach will not accept them in the weightlifting section and recommend that they take up a more “suitable” sport for their age, such as sports games, swimming or figure skating. I fully admit that in many cases this is what happens in large cities where there are swimming pools, stadiums and ice palaces. Well, if this is a village, a small regional center, a small city, of which there are a huge number in Russia and in which there is no opportunity for children to engage in many sports, what kinds of sports do children living in large cities have the opportunity to do? Often it is in such small settlements that young high-class weightlifters are trained, if coaches live there - fans of this sport. It is to such fans of weightlifting that the brothers Andrey and Mikhail Popov from the village of Pereyaslavskaya, Bryukhovetsky district, Krasnodar Territory, belong. By the way, this small village in terms of population (about 8 thousand) is generally a forge of outstanding athletes in a variety of sports. Honored masters of sports in acrobatics, multiple world champion Vasily Machuga, Olympic champion Alexander Moskalenko, members of the Russian national team in rowing, boxing, cycling, etc. grew up here. among young men 17 years old, which took place on May 12-16, 2004 in the city of Bryansk, is a strong confirmation of this. Three champions of Russia in weightlifting from one village - this was not achieved even by many large cities. From the age of seven, Andrei Molchanov, a pupil of the Popovs, has been training in the weightlifting section, who at the age of 15 at this championship became the champion in the weight category up to 77 kg with results in the snatch 140, clean and jerk 170 kg and in the combined event - 310 kg, and at the zonal championship of Russia this young athlete showed generally phenomenal results for this age - 150, 190 and 340 kg, respectively.

Of course, you should be aware that working with this age group has specific features. Children and teenagers are not a copy of an adult. Numerous studies by scientists have shown that the activity of internal organs and systems in childhood, and especially during puberty, differs markedly from that in adulthood. Adolescence replaces the period of childhood, which is characterized by relatively calm and even growth in human development. During puberty, there is a rapid development of the whole organism. Proof of this is a significant increase in height, weight, chest circumference and muscles, increased heart function, profound changes in the activity of the central nervous system, and especially in the activity of the sex glands. This period lasts for boys on average from 12 to 16 years, and for girls - from 11 to 15 years. Childhood and adolescence are the main periods in a person's life on the way to the full flowering of his powers, when physical and functional capabilities are improved, personality and character are formed.

When starting training with young weightlifters, it must be taken into account that modern adolescent children in their physical development differ significantly from their peers of the 50s-70s. Modern Russia has been carrying out radical socio-economic transformations for almost 15 years, which have led to a significant decrease in the standard of living of people, especially in small towns. A new young generation has grown up, which, in terms of their state of health and physical development, is significantly inferior to their peers who lived several decades ago. Therefore, careful control over the physical and functional state of young weightlifters is the most important requirement in the work of a coach in this sport.

2.1.1. Skeletal system

After the birth of a person and on average up to 24-30 years, ossification of the skeleton occurs. Together with the muscles, the skeleton makes up the musculoskeletal system. The bones act as levers in it, which move as a result of muscle contraction. In the human skeleton, the skeleton of the body, the skeleton of the upper and lower extremities, and the skeleton of the head are distinguished (Fig. 2.1).

The spine is the support of the body and consists of 33-34 vertebrae and their connections. Five sections are distinguished in the spine: cervical - 7 vertebrae, thoracic - 12, lumbar - 5, sacral - 5 and coccygeal - 4-5 vertebrae. In an adult, the vertebrae of the sacral and coccygeal regions are fused and represent the sacrococcygeal bone. Ossification of the cervical, thoracic and lumbar vertebrae ends by the age of 20, sacral - by 25, coccygeal - by 30 years. The fastest growth of the spine in length is observed in the first year of life. Then this growth slows down and accelerates again in boys from 9 to 14 years old, then again slows down to a greater extent from 14 to 20 years old. By the end of puberty, the growth of the spine in length almost ends. The length of the spine is approximately 40% of the length of the body.

The spine after birth acquires four physiological curves (Fig. 2.2). With age, these curves increase. In adults, the first curve of the spine (cervical) is moderate lordosis, the second curve is severe thoracic kyphosis, the third is severe lumbar lordosis, and the fourth is severe sacrococcygeal kyphosis. In young weightlifters, with proper physical development, these bends do not have pathological changes.

But if a young athlete performs an exercise incorrectly or maintains an unnatural posture for a long time (for example, slouching in the starting position during sports activities, sitting incorrectly at a desk at school), then an abnormal change in the curvature of the spine may occur (Fig. 2.3).

If children have thoracic scoliosis, they should be referred to a doctor for therapeutic exercises. Various sports exercises, walking with correct posture, the development of back muscles contribute to the correction of some forms of scoliosis.

Rice. 2.1. Human skeleton

1 - skull, 2 - spinal column, 3 - rib, 4 - collarbone, 5 - sternum,

10 - femur, 11 - tibia, 12 - fibula,

13 - foot bones, 14 - ilium

The chest is made up of 12 pairs of ribs and thoracic vertebrae. The ossification of the ribs ends at about 18-20 years of age. By the age of 12-13, the chest takes the form of the chest of an adult, but is smaller.

During puberty, there is an intensive increase in the chest. The ossification of the clavicles, shoulder blades and humerus ends by the age of 20-25, the bones of the wrist - by 10-13, the wrist - by 12, the phalanges of the fingers - by 9-11 years. Complete ossification of the pelvic bones and the fusion of its individual parts is completed by the age of 20-25. Growth retardation and abnormal fusion of the pelvic bones can occur with long and improper standing, sitting, malnutrition. The bones of the legs - the femur, tibia and fibula - ossify by 20-24 years, metatarsals - by 17-21 and phalanges - by 15-21 years.

The human foot forms an arch, which rests on the tubercle of the calcaneus and on the heads of the metatarsal bones. The development of leg muscles contributes to the formation of a full-fledged foot.

According to a number of experts, with prolonged standing, carrying heavy loads and wearing narrow shoes in adolescence, flat feet develop. Research carried out by Professor A.I. Kurachenkov, showed that weightlifting in adolescence, in which a significant place is given to general physical training, does not lead to the development of flat feet. When doing weightlifting, there is a specific change in the skeleton that is not inherent in other sports. This change is manifested in bone hypertrophy, an increase in the joints of bones and tendons.

Thus, in adolescence and youth, intensive ossification of the skeleton occurs, but the complete completion of this process is observed already in adulthood. Therefore, the use of maximum weights in the training of adolescents aged 12-15 years should be strictly regulated. Incorrect exercise, an unnatural posture when lifting the barbell can not only develop stable incorrect barbell lifting skills, but also lead to adverse changes in the state of the musculoskeletal system (abnormal fusion of the pelvis, curvature of the spine, etc.). The development of the skeleton is significantly influenced by nutrition and hygiene conditions both at home and in training.

2.1.2. Muscular system

When preparing young weightlifters, special attention should be paid to the harmonious development of the muscular system. Muscles are the active part of the musculoskeletal system. Thanks to their reduction, a person is able to perform a variety of movements in the surrounding space (Fig. 2.4 A, B).

By the age of 15-16, the development of muscle tissue is mainly completed. It becomes the same as in adults. This is a favorable factor for performing weightlifting exercises in adolescence. At the same time, tendons in adolescents are less developed than in adult athletes, which is important to consider when dosing a training load with weights. The inclusion of various acrobatic and gymnastic exercises, sports games, etc. in the training of young weightlifters contributes to a more effective development of the tendons.

Skeletal muscles, being the active engine of the body, perform dynamic and static work. The first is characterized by the movement of the body in space or body parts relative to each other. When lifting the bar, mechanical work (A 1 ) can be measured by the product of the weight of the load (P) by the lift height (h) and expressed in kilogram meters: A 1 = R? h. We will use this formula in the future when determining the training load in the special training of young weightlifters.

Along with dynamic work, the muscles also perform static work (A 2 ) - constantly hold parts of the body in a certain position relative to each other. It can be found by multiplying the amount of force (f) developed by the muscles by the time of its action (t): A 2 = fxt.

When developing the optimal load in static stresses, we took into account the peculiarities of the work of the muscular system. As our studies have shown, certain muscle groups in young weightlifters are amenable to more effective training when using exercises of both a dynamic and static nature (for example, exercises for developing the muscles of the abdominal press, lumbar, lower extremities, etc.).

Dynamic and static muscle tensions complement each other: statically working muscles provide the initial position of the body (for example, the starting position before lifting the barbell), on the basis of which dynamic work is performed; on the other hand, the transition from one position to another occurs as a result of movements, i.e. through dynamic work. Thus, the quality of physical exercise performance will be the better, the more effectively both types of muscle activity are used in sports training. In this regard, already in the initial training of young weightlifters, it is necessary to use exercises not only of a dynamic, but also of a static nature. This will ensure the creation of a good base for the growth of sports results.

Human muscular activity has a significant impact on vegetative functions (blood circulation, respiration, etc.). In turn, the activity of the internal organs reflexively affects the functional state of the skeletal muscles (viscero-motor reflexes). Consequently, motor and autonomic functions are closely interrelated. Sports training contributes to the improvement of physical qualities (speed, strength, endurance), and this leads to the improvement of vegetative functions, which is manifested in an increase in the delivery of nutrients and oxygen to the muscles, in an increase in pulmonary ventilation during work, etc. Active muscle activity in adolescence, associated with weight lifting, not only contributes to the development of strength, but also has a beneficial effect on the improvement of autonomic functions.

During puberty, the intensity of muscle mass growth increases, compared with childhood. This is due to increased secretion of androgens of the adrenal cortex, stimulating an increase in muscle mass in adolescence. If in boys of 8 years old the weight of muscles in relation to the total body weight is 27%, then by the age of 15 this value reaches 33, and in adults - 40%. Especially noticeable in adolescents is the increase in the weight of the muscles of the flexors and extensors of the shoulder.

2.1.3. The cardiovascular system

As you know, from birth to 16 years, the human heart increases by more than 10 times, and the growth in heart size is uneven in different periods of life. The most intensive increase is observed in the first year of life and in the period from 13 to 16 years.

So, during puberty, the volume of the heart increases by more than 2 times, while body weight during the same period - by 1.5 times. The rapid growth of the size of the heart leads to the fact that its volume does not correspond to the lumen of the vessels that do not reach anatomical maturity in adolescence. This discrepancy is one of the causes of high blood pressure in adolescence. Therefore, high blood pressure in some 13-14-year-old schoolchildren is not necessarily a sign of an unfavorable state of the cardiovascular system.

The volume of the heart in a 10-year-old boy is 130 cm?, and in a 13-year-old teenager it is 443 cm?. In adolescents aged 13-14 years, juvenile cardiac hypertrophy (i.e., an increase in heart volume) is often observed. For example, with hypertrophy, the diameter of the heart in adolescents can reach 12.4 cm (normal - 9.5-11.2 cm). As a rule, young athletes with this heart shape have good physical development. The process of puberty in them does not differ from that of their peers with a normally developed heart, and sometimes overtakes it. Such adolescents do not complain about the work of the heart. Their arterial blood pressure is normal, but in some cases there may be an increase in systolic pressure up to 130-140 mm Hg. Art. Juvenile hypertrophy is a reversible process. With a good functional adaptability of the cardiovascular system, there are no grounds for any restrictions in weightlifting. At the same time, it is recommended to establish special medical and pedagogical control for adolescents with cardiac hypertrophy.

The opposite of juvenile hypertrophy of the heart is a small heart, often combined with an asthenic constitution, i.e. high stature, a large gap in body height and weight, narrow chest, long limbs. Such a heart is distinguished by its small size, median location in the chest, and reduced diameter. Adolescents with a small heart often complain of fatigue, headache, dizziness, palpitations, shortness of breath during physical work of moderate intensity. Such teenagers are not allowed to take part in the weightlifting section without the special permission of the doctor of the children's polyclinic.

Heart rate depends not only on age, but also on gender. The pulse in boys is somewhat less frequent than in girls of the same age.

In the process of age development, the pulse rate decreases and in adolescence approaches the value recorded in adults (Table 2.1).

One of the characteristic features of childhood is the presence of arrhythmias, i.e. fluctuations in the heart rhythm. In most children, fluctuations in the rhythm of heart contractions are associated with phases of respiration. In the inspiratory phase at its height, the heart rate quickens, in the expiratory phase - at its end - it becomes less frequent. The frequency and severity of arrhythmia in different age periods are not the same. In early childhood, arrhythmia is quite rare. The degree of its severity at this age is negligible. From preschool age to 14 years of age, significant respiratory arrhythmia is often noted (the range of rhythm fluctuations is more than 30 beats per minute). At the age of 15-16 years, a sharp respiratory arrhythmia occurs in isolated cases. This age is characterized by a moderate and mild degree of sinus arrhythmia.

Table 2.1

Heart rate in children and adolescents

(according to A.F. Tur)

Heart rate is a very labile indicator of the functional state of the cardiovascular system. It changes under the influence of both internal and external stimuli. For example, when the ambient temperature changes, the pulse rate changes. An increase in temperature causes an increase in heart rate, a decrease causes a decrease. Emotions, as a rule, lead to a sharp increase in the rhythm of cardiac activity.

During muscular activity, there is a significant increase in heart rate. The heart rate during and after work reaches an average of 180-200 beats per minute. During intense muscular activity, age differences are noted. They are expressed primarily in the rate of deployment of hemodynamic shifts that provide increased oxygen consumption during intense muscle activity. The period of entry into work decreases with age. The shorter period of entry into work in the older age groups compared to the younger ones is due to the greater potential lability of the nervous mechanisms that regulate blood circulation, providing a quick restructuring of this function to a new level.

The increase in heart rate during intense muscular activity increases with age. So, in 8-year-old children, the increase in frequency in the first minute of work is 50% relative to the initial value; in 17-year-old boys it is 72%. The time to stable heart rate during work also increases with age. An increase in the time of stability of heart contractions in the process of muscle activity suggests that with age, the body's ability to long-term stable intensification of the circulatory function increases. The recovery time for heart rate with the same load at older ages is significantly reduced compared to younger ones.

An essential factor that provides all organs and tissues with nutrients and oxygen is the stroke and minute volume of blood.

Stroke volume - the amount of blood ejected by the heart during systole to the periphery, minute - the amount of blood ejected in 1 minute. The latter value thus represents the product of the systolic volume and the number of systoles per minute.

The most accurate methods for determining the impact (minute) volume are the Grolman gas analytical method modified by I.I. Khrenova, physical methods and methods of determination using mechanocardiography.

Despite the great accuracy, these methods are very laborious and are of little use for muscular activity. Therefore, many attempts have been made to indirectly determine the value of minute volume.

In practice, to assess the efficiency of the blood supply to the body, they use the calculation of the minute volume of blood, determining its value according to blood pressure and pulse rate (Starr formula), as well as calculating the coefficient of efficiency of the blood supply to the heart (CEC). The coefficient of efficiency of blood supply is equal to the product of pulse pressure (PP in millimeters of mercury) and heart rate (HR): KEK = PD? Emergency. The systolic volume of the heart in millimeters (SD) according to the Starr formula is calculated as follows:

CO \u003d 100 + 0.5 PD - 0.6 DD - 0.6 V,

where PD and DD are pulse and diastolic pressure in millimeters of mercury, B is age in years. Minute volume in millimeters is equal to the product of systolic volume and pulse rate.

ON THE. Romantseva modified the Starr formula, since the value of the minute volume of the heart in children from 8 to 14 years old, calculated using the Starr formula, significantly exceeded the value of the minute volume obtained by direct measurements. The modified formula looks like this:

CO \u003d 80 + 0.5 PD -0.6 DD -2 V.

According to the literature data, obtained both by direct methods for determining the stroke and minute volumes of the heart, and indirectly, the value of these parameters increases with age.

It should be noted that with age, the systolic or stroke volume of the heart changes more intensively than the minute, as the heart rate decreases at the same time.

In newborns, the stroke volume is 2.5 ml (M.T. Matyushonok). By the 1st year of life, it reaches 10.2 ml, at the age of 7 years it is 23 ml, at 10 years old - 37, at 12 years old - 41 ml (L.I. Mursky). At the age of 13-16, the value of cardiac output reaches 59 ml (M.A. Shalkov). In an adult, the stroke volume is 60-80 ml.

As for the minute volume of blood, as mentioned above, it slightly increases with age: in children under 1 year old it is 0.33 l, at the age of 1 year - 1.2 l, at 5 years old - 1.8 l (L .I. Mursky, 1961). M.A. Shalkov (1941) for children aged 6-16 established the following norms of minute volume (Table 2.2).

Table 2.2

Norms of cardiac output in healthy children

(according to M.A. Shalkov)

It should be noted that the stroke and minute volume of the heart, both in absolute terms and in terms of 1 kg of weight, is associated not only with age, but also with physical development, namely with height and weight (Table 2.3). The most physically developed people have the highest minute and stroke volume of the heart.

Table 2.3

Dependence of the relative power of the heart

(systolic volume in cm 3 per 1 kg of body weight

(according to I.I. Khrenov)

The known difference in the values ​​of stroke and minute volume depends on gender: the values ​​of stroke and minute volume in boys and men are slightly higher than in girls and women (I.I. Khrenov). When comparing the values ​​of minute volume with the values ​​of arterial pressure, there is no close relationship between these indicators. There are low numbers of arterial blood pressure, combined with high values ​​of systolic volume, and vice versa.

With normal blood flow to the heart and sufficient blood flow, the value of the minute volume of the heart is directly dependent on the activity of the heart.

With an increase in the work of the heart, the minute volume increases, with a weakening, it decreases. That is why during muscular activity, which makes increased demands on the body and, first of all, on the heart, the volume of ejected blood in all age groups of healthy people, as a rule, increases. However, the minute volume of blood during work in adolescents increases less than in adults.

The increase in the minute volume of blood during exercise of moderate power in all ages occurs due to an increase in stroke volume. At extreme loads, requiring a large mobilization of the cardiovascular system to provide individual organs and tissues with oxygen, the cardiac output increases both due to an increase in stroke volume and due to increased heart rate. The younger the age, the faster during work the small value of the systolic volume in children is compensated by the high pulse rate, which determines the large required minute volume.

When working with young athletes, it is necessary to pay attention to the heart rhythm. A heart rate of less than 60 beats per minute indicates that a teenager develops bradycardia (decrease in heart rate), which does not always depend on sports at this age. Studies of bradycardia in adolescence have shown that it is not necessarily a sign of negative heart function. Usually such teenagers go in for sports on an equal basis with everyone under the supervision of a doctor. The opposite state of the heart to bradycardia is the so-called sinus tachycardia, i.e., an increase in the heart rate at rest. The development of tachycardia may be indicated by a resting heart rate greater than 80 beats per minute (bpm). In some cases, it reaches 100-120 beats per minute in adolescents at rest. The cause of tachycardia can be acquired and congenital heart defects, a small heart. Adolescents with tachycardia should be under special medical supervision.

2.1.4. Respiratory system

Lung capacity gradually increases during the development of the organism. In the total capacity, a number of components are distinguished. The most commonly used measurement of the vital capacity of the lungs, ie. the amount of air that can be exhaled with the deepest exhalation after the deepest inhalation. The vital capacity of the lungs is measured in children from 4-6 years of age. The measurement procedure is associated with the need to arbitrarily deepen the respiratory movement. Small children are not able to understand and perform such a task. The values ​​of the vital capacity of the lungs differ depending on the characteristics of the development of the child, as well as on the conditions of life and upbringing. As the child grows, the vital capacity increases. For example, according to one of the studies, the vital capacity at 4 years was equal to an average of 1100 ml, at 6 years - 1200 ml, at 10 years - 1700 ml and at 14 years - 2500 ml (M.A. Shalkov).

The vital capacity of the lungs depends on the size of the body. Therefore, when assessing this indicator, it is necessary to take into account the physical development of the child. One of the techniques used for this purpose is the calculation of the so-called vital indicator, i.e. the number of milliliters of vital capacity per 1 kg of body weight. However, such a calculation may not give satisfactory results due to significant individual weight fluctuations at different periods of children's development. Better matching with growth. In one of many similar studies, data were obtained that the vital capacity of the lungs in boys older than 5 years is 2.157? 10 -3 ? R 2. 81 ml, and in girls 1.858? 10 -3 ? R 2 ,82 ml, where P is height in centimeters (Cook, De Munth, Hovatt, Hill).

The vital capacity of the lungs, other things being equal, is greater in children who systematically engage in physical exercises. In adolescents at the age of 13-14, values ​​of 3-4 liters or more can be observed, respectively, up to 130-150% or more of the proper value. The vital capacity is especially high when doing sports that develop endurance - swimming, running, skiing, rowing, etc. The increase in vital capacity in young athletes occurs due to the growth and development of the body under the influence of physical exercises. In addition, training increases the range of respiratory movements, the mobility of the chest. As a result, both inhalation and exhalation deepen, and this also increases lung capacity. At the same time, selection is important when recruiting sports teams, schools or sections. Athletes often become those children whose lungs were well developed even before training.

Vital capacity is the sum of tidal volume, inspiratory reserve volume, and expiratory reserve volume. During quiet breathing, the tidal volume is approximately 10-20%, the expiratory reserve volume is 30-40%, and the inspiratory reserve volume is 45-55% of the vital capacity of the lungs. There are methods by which it is relatively easy to measure the residual volume of air remaining in the lungs after the deepest possible exhalation. Residual volume measurement is associated with the determination of another value that is important for assessing lung volumes. This is the value of the functional residual capacity, i.e. sum of residual volume and expiratory reserve volume. Functional residual capacity refers to the amount of air remaining in the lungs after a normal exhalation. Its changes as the child grows correlate well with body length. Cook, De Muth, Hovatt, Hill give the following formulas for functional residual capacity (F.R.E.) in milliliters.

F.O.E. = 7.312? 10 - 4 ? R 2 ,93 boys

F.O.E. = 4.781? 10 - 3 ? R 2 ,54 girls

Residual volume measurement makes it possible to calculate the total capacity, i.e. sum of vital capacity and residual volume. In children aged 5 to 17 years, the residual volume is on average 20-24% of the total lung capacity, about the same as in adults. In trained children who systematically go in for sports, the residual volume is equal to a slightly smaller proportion of the total capacity, on average 18%. Consequently, athletes can exhale more fully. It is clear that in this case, the absolute values ​​of the residual volume are greater in athletes, as are the values ​​of vital capacity. Of practical interest is the calculation of the so-called functional residual capacity coefficient, i.e. ratio of residual volume to expiratory reserve volume. Both volumes must be calculated for this purpose as a percentage of total lung capacity. The coefficient of functional residual capacity is lower in young athletes compared to untrained children. In one of these studies, average data were obtained: for young swimmers 10-16 years old, 73.2 + 3.2%, and for their untrained peers, 92.0 + 3.2% (A.I. Osipov). Such large differences are due to the fact that the relative values ​​of the residual volume in athletes are smaller, and the expiratory reserve volume is larger than in untrained people. Oppositely directed shifts of these indicators make the differences in their relations especially noticeable.

In absolute terms, respiratory minute volume increases with age in line with the increase in metabolism. As well as the level of exchange, the relative values ​​of pulmonary ventilation, recalculated per 1 kg of weight or per 1 m? body surface, are the smaller, the older the children (Table 2.4). Due to the slowing and deepening of respiratory movements, tidal volume increases with age to a greater extent than ventilation.

Table 2.4

Indicators of lung ventilation

(average data according to M.A. Shalkov)

Muscular activity increases minute volume of breathing more or less in proportion to the severity of the load. The older children are, the more intense muscular work they can perform and the more they can increase ventilation during work.

Under the influence of training, it is possible to perform the same work with a smaller increase in lung ventilation. At the same time, trained children are able to increase their minute breathing volume during work to a higher level compared to their peers who do not exercise (A.N. Krestovnikov, N.V. Zimkin). The older the children, the more the effect of training can affect them and the more changes can occur in their body under the influence of exercise. At the age of 14-15, training causes almost as significant shifts in adolescents as in adults. At 10-12 years old, the possibility of such changes in respiration and gas exchange is noticeably less.

The limit of increased breathing (the so-called maximum ventilation of the lungs) cannot be reached during muscular work. A real maximum is obtained only with an arbitrary increase and deepening of breathing for 15-20 seconds. Then the result is recalculated for a minute. The value of maximum ventilation of the lungs, as well as vital capacity, can only be measured in sufficiently large children, after the child is able to understand and perform such a task. Sometimes they also use the concept of breathing reserve, i.e. about the difference between the maximum ventilation (limit) and the minute volume of breathing under these conditions of observation.

Respiration limit increases with age. According to the results of one of these studies, the maximum ventilation of the lungs turned out to be on average 42 l/min at the age of 6, 48 l/min at the age of 10, and already 68 l/min at the age of 14 (M.A. Shalkov). To assess the maximum ventilation, it is customary to compare the measurement results with the proper values ​​calculated using various formulas. In such formulas, they proceed from the possible deepening of breathing, i.e., the vital capacity of the lungs and the optimal (to reach the limit) quickening of breathing. The Dembo formula allows you to determine the maximum ventilation of the lungs in liters. It is equal to half the proper vital capacity of the lungs in liters, multiplied by 35. The greater the breathing limit for a given person during voluntary hyperventilation, the more, all other things being equal, it is possible to increase ventilation during muscular work. In young athletes, the breathing limit is greater than that of their untrained peers and often reaches 150-200% of the proper value. In table. 2.4 presents the average data of one of these studies conducted in schoolchildren aged 10-16 years.

Pulmonary ventilation ensures the exchange of gases between the atmosphere and the alveoli. The younger the children, the lower their percentage of carbon dioxide and the greater the percentage of oxygen in exhaled and alveolar air. Accordingly, the percentage of oxygen use is also lower (Table 2.5). This means that lung ventilation is less effective in young children than in adults. For the same amount of oxygen consumed and carbon dioxide released, a child needs to ventilate the lungs more than adults. This dependence is conveniently expressed by the value of the so-called respiratory equivalent, which is equal to the quotient of the division of the minute volume of respiration by the oxygen consumption per minute, multiplied by 10. According to M.A. Shalkov, it decreases from 3.8 in the 1st month of life to 2.4 in 14 years.

Table 2.5

Mean values ​​of maximum ventilation of the lungs

(according to A.T. Osipov)

The low efficiency of ventilation in young children can be explained, apparently, by their frequent and shallow breathing. With shallow breathing, a relatively large proportion of the respiratory volume is the volume of "dead" space. As a result, alveolar ventilation, i.e. the air actually participating in gas exchange is a relatively smaller part of the minute volume.

As a result, the exhaled air consists to a greater extent of the air of the “dead” space, i.e. from atmospheric air, and the percentage of carbon dioxide release and the percentage of oxygen use from a given volume of breathing is less in it.

Depending on the condition of the child, ventilation may be more or less effective. Many young athletes ventilate their lungs more efficiently than their untrained peers. Athletes often have relatively higher percentages of carbon dioxide excretion and oxygen utilization than non-athletes. However, a systematic study of many young athletes reveals that their ventilation efficiency may not differ from the level of untrained peers. An increase in metabolism during muscular work usually leads to the fact that the air ventilating the lungs is used more fully. When fatigued, or when the work is too hard for an undertrained child, the release of carbon dioxide and the use of oxygen, on the contrary, decrease.

2.1.5. Higher nervous activity

The development of the organism occurs with its constant adaptation to the influence of the external environment, the development of the necessary adaptive mechanisms that ensure the effective functioning of all human organs and systems. On this basis, physiological changes associated, for example, with physical exercises occur long before they are performed as a result of the activity of the nervous system, which regulates changes in both physiological functions and volitional efforts.

The main properties of the nervous system are innate and, therefore, largely determine its motor capabilities (Z.I. Biryukova). These features of the nervous system create certain prerequisites for practicing a particular sport. For example, a high-class weightlifter is distinguished by high mobility and speed of reaction, the ability to maximize the concentration of nervous processes when lifting a barbell, especially limiting weights. However, under the influence of external factors, the type of nervous activity (genotype) can change significantly, forming a phenotype that includes both acquired and developed properties.

Speed-strength exercises improve the ability to differentiate stimuli and increase the excitability of nerve centers in 12-14-year-old adolescents (NA. Fomin, VP Filin, 1972). It is also known that during puberty (in boys from 12 to 16 years old) there is a general increase in the excitability of the central nervous system. All verbal and motor responses can be accompanied by excessive movements of the arms, legs and torso. In the behavior of adolescents, there is a clear predominance of excitation over inhibition. Often, the response in its strength and character is not adequate to the stimuli causing it. Adolescents' speech slows down, answers to questions, as a rule, become concise, stereotypical, and the vocabulary seems to be depleted. Often you have to ask additional questions to get a complete answer to the question asked. There is experimental evidence that the response to verbal stimuli in adolescents is slower than the response to a visual or sound stimulus (P.P. Balevsky). In this regard, for beginner weightlifters, it is necessary to use various teaching methods - both verbal and visual.

It should be borne in mind that the adolescent brain is under unfavorable conditions of nutrition and oxygen supply due to the fact that the growth of the cardiovascular system lags behind the growth of the body. In addition, due to the increase in the functions of the adrenal medulla, the content of adrenaline in the blood increases, which leads to a narrowing of the blood vessels. These features of development are sometimes the cause of mild fatigue in young athletes during training, even with small loads, and often headaches.

Adolescence is a period of restructuring of the body, causing a significant stress of all nervous activity, requiring a reasonable and careful attitude of adults towards young athletes.

When choosing a sports direction for their child, parents try to find out in advance about the positive and negative aspects of this type. Those who want to send the baby to the weightlifting section or to powerlifting are wondering if physical activity will affect the growth of the child?

Do barbell workouts make you look shorter?

It is noticed that they can grow up to 19 years, up to 22. The active phase of growth occurs:
U - from 11 to 13
U - from 13 to 16.
During this period, a child can add 7-10 cm per year. Therefore, parents do not want to give them to the weightlifting section, so as not to slow down this process.

There is an opinion that active exercises and heavy loads will harm a fragile body. Growth hormones will be spent on muscle growth, energy and nutrients will be directed in the wrong direction. The growing body will not cope with the load, which will negatively affect the formation of the child's body and the work of its internal organs and systems.

Research has shown that this is not the case. Subject to proper nutrition, all norms for performing exercises and accurate calculation of loads, weightlifting will not bring any harm to health. Physical education, on the contrary, helps to strengthen both bones and muscles.

If you measure a person’s height before and after exercising with a barbell, then it will change and the person will “shrink” by 3 cm. This is an acceptable norm.

The growth of any person during the day changes. Without loads, the difference in measurements taken in the morning and in the evening will be 1 - 2 cm. If you carried heavy bags or dragged furniture, then you could become shorter by 1.5 cm or more, for a while.

Changes will be associated with compaction of the intervertebral vertebrae. With age, any person begins to decrease in height. At 60, you will become 2-3 cm lower, and at 80 - by 5-7 cm, unlike 22 years old.

Power loads do not affect human growth

Usually, in the sections associated with heavy physical exertion, such as powerlifting, weightlifting and bodybuilding, they begin to recruit kids at the age of 8–9 years. The child's body begins to take shape, and physical activity helps to properly develop the bone structure and muscles. There is an opinion that barbell exercises slow down these processes. Allegedly, the barbell on the shoulders presses on the spine and this does not allow the child to grow.

A weightlifting coach will tell you that this is a myth.

About 8 hours a week are spent on training, the net time the barbell is on the shoulders will be only 30 minutes. This is 0.3% of the total time, the remaining 99.7% nothing presses on the spine, and the child grows.

It has been proven that physical activity, including exercises with a barbell, stimulates the production of growth hormones. Most of them in children go to the development and growth of the bone skeleton.

Judging by the height of famous weightlifters, it should be noted that stocky and short people are more stable on their feet. Due to this, success is achieved mainly by undersized strong men. They can lift more weight and hold it longer.

So if you or your child wants to do weightlifting, don't hesitate. Any physical activity under the supervision of an experienced trainer will not bring harm.
