THE USE OF MATHEMATICAL TECHNIQUES IN THE STUDY OF THE DYNAMICS OF HIGH PHYSICAL EXERTION

The possibility of applying methods of mathematical modeling in the evaluation of human performance under high loads. As an example, used medical information about players in the Premier League of Russian

The behavior of the human body in extreme physical activity is of great interest to various spheres of human activity. In order to perform their duties, the people working in such conditions (e.g., astronauts, pilots and rescuers) must be in good physical training. The athlete’s body adapts to systematic high (sometimes close to the limit) exercise, in connection with which changes and its physiology. Continue reading

Preparing dogs for competition

Training and practical exercises to perfection, of course, important, but not enough. Without special training dogs for competition, you may get a dog that “knows” that she is in the ring and changes its behavior. This happened to my first dog, which I played at a high level. It worked fine in the first event, but gradually it became half as well as in training. And when I finally realized that we were in trouble, it was too difficult to handle.

Now training dogs to work on the competition is a large part of our training. There are different aspects of the competition, which can work separately. Most of them can be practiced with a puppy or young dog. Here are some things that you need to work out before the competition:

Prepare your dog for long work without encouragement. The biggest difference between training and competition is usually thatwe are much more likely to encourage a dog in training. It makes our dogs are smart, understanding the difference between “in the ring” and “beyond the ring”. Continue reading

Sports how not to hurt yourself

The physical form of each of us is constantly changing and the changes are not always like us. How to achieve good physical shape and not to lose it over the years? This is the main question in this article.

Everyone is more or less familiar with exercise, and each type of stress on the body has its own peculiarities. Even from birth we are not on an equal footing: someone better suited to run, someone – to swimming. Thus, certain abilities allow us to develop your own style of execution of any movement and the adoption of any poses.

Therefore know:

Each body ITS limits.

Almost all people from birth-weak and weak-willed, and therefore can’t cause yourself harm by excessive loads. During the training of the people, reaching a certain point in the practice stops. And despite the fact that such people rarely win sports awards, they correctly relate to your body. Why? The reason is that the other part of future athletes accustom yourself to constantself-conquest and oppression of his own body. This is the path of great achievements, rapid growth and at the same time the inevitable fall. Continue reading

Adaptation to physical loads

Physical health can be improved in the process of the sport and by means of physical culture. And in that and in other case it will change, and all these changes will lead to three main:

— first of all, improve the physique, increase the amount of muscle mass, reduced amount of fat, change posture;

— secondly, improvement;

and thirdly, increase the level of physical fitness, pryobretaetsya endurance, speed and power quality, coordination ability and flexibility.

These changes, called adaptation, can occur under the influence of any exercise. There are three types of adaptive changes:

– short-term adaptation, the essence of which are adaptive changes in the human body during exercise or immediately after their completion;

– current adaptation, the indicator of which is the magnitudeof the daily fluctuations in the level of the physical condition of man. Any stress (physical, mental) impact on the human condition. Even a healthy person feels the changes in his condition, the more noticeable they are people with different disabilities in health; Continue reading

exercise and rest as interrelated components of process exercises

Load and rest as interrelated components of the process of exercise: the “external” and “internal” side of the load, volume and intensity as part of the load, recreation

Load – the impact of physical exercise on the human body, causing a strong reaction from its functional systems (V. N. Platonov, 1987).

Load – the number of exercises performed, the time spent on classes and other indicators. The load – response of the body to work.

For most physical exercise in their total load on the body adequately characterized by the following components (V. M. Zatsiorsky, 1966):

Intensity – the magnitude and direction of the impact of physical exercise on the human body (speed, pace). Changes in the intensity of exercise has a direct impact Continue reading

The concept of physical activity

Umstvenny Fizicheski[1]The published material is infringing? please let us know.

The concept of “physical activity” shows the obvious fact that any of the exercises connected with the transition energy of the body functioning at a higher than at rest, level.

Example:

If you take the amount of energy in the supine position “1”, then a slow

walk at a speed of 3 km/h will increase the metabolism in 3 times, and running with acropetally speed and similar exercises in 10 and more times.

Thus, the exercise requires a higher, relative to its rest position power consumption. The difference that occurs in energy consumption between the state of motor activity (e.g. walking, running) and the rest refers to the physical Continue reading
