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
Overtraining is a physiological condition in which there is a violation of the fitness of the human body after a regular physical stress. Overtraining is accompanied by the appearance of fatigue and decreased ability to perform physical exercise. What are the disorders on the physiological level are evolving state of overtraining? What are the consequences of the consequences of such conditions and whether they can lead to poor health? How to provide for the body’s recovery from overtraining?
Overtraining occurs most frequently in a systematic and excessive pace training in sports and fitness clubs in those who had not previously received such exercise. In people who have not yet adapted to the increased motor activity in sports, recovery after intense workouts cannot provide full replenish energy in the body and maintain the health of muscle fibers. When this physiological condition is violated, the activity of the whole organism. Particularly vulnerable to such danger nervous and cardiovascular systems.
There are several varieties of overtraining. Continue reading
How to learn to swim. Why it is useful swimming. Swimming for weight loss. Techniques and styles of swimming
To learn how to swim is helpful. The benefits of swimming for health. The main styles of swimming.
Swimming is the ability to move on water and under water due to the movements of his own body. The ability to swim has the most living organisms on the planet, including man. However, unlike walking and running in humans have not developed the automatic ability to swim. As in cats, dogs or even more aquatic animals. Swimming requires the formation of a complex motor reflexes . In this respect, this physical activity like riding a bike, rollerblading, running on jumpers, etc. to Teach swimming
and can infants and especially adults. During swimming training activated by a bark of the big hemispheres of a brain.
Any heart surgery, including coronary artery bypass, must be accompanied by a rehabilitation period, which will enhance the outcome and support the body in proper shape. Otherwise all the doctors ‘ efforts may be in vain.
Also important, and the period after the passage of the rehabilitation that requires patient adherence to the rules of the diet, a special diet and a specific program of physical activity, the goal being to maintain
muscle tissue in good shape.
The essence of rehabilitation
The whole process of rehabilitation after CABG may take three to five months and contain a whole individual complexes of events. Such complexes include the preparation of an individualized plan for a particular person with all the characteristicsof the organism. Also provides for regular physical exercises with clear allocation of specific parts of the body and the entire body. Continue reading
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.
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
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
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
It is known that regular physical activity and sports practice many organs and systems of the human body, which, of course, improves health and improves health.
The movement is a very important component of health. It stimulates many processes in the body. Child couldn’t grow into a full adult human if he did not commit such a huge amount of different movements.
In our body contains about 65% of liters of liquid, and it must be continuously circulated, so that the cells received all necessary materials, and waste is removed. The liver, kidneys, lungs, skin and intestines must be healthy and clean in time to eliminate the toxins.
The multiple increase circulation of fluids in the bodycontributes to the movement: running, walking, exercise. When we move, our muscles contract, the liquid is extruded into the blood stream, and venous blood moves to the heart.
Thanks to increased blood circulation and respiration, are emitted from the body the toxins of fatigue, resulting in the impact on human performance. Continue reading
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.
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
Many have heard about the energy ( in Chinese QI. Japanese — KI. Vietnamese — KHI. in India — Prana ) and its role in human life. Every day we are fed by the energy of th air, food and this energy gives us immunity and the ability to live and work. If a person has little power or it’s dirty, he was often sick. Much everywhere is written about the training of endurance, but no one focuses when you can and what are the consequences.
Endurance training is divided into two stages of aerobic and anaerobic .
Consider anaerobic because aerobic exercise, tend to ignore or just don’t know. In simple words anaerobic training is when little oxygen (classes), the ragged rhythm of practice, loads are constantly changing, great mental stress, fatigue, ‘t understand, can’tget it). Heart rate above 150 beats per minute. This type of training for endurance training is necessary, but should be considered a necessary human condition for anaerobic training, is good health, good condition of the muscles, tissues, organs, a large amount of energy (KHI). During anaerobic exercise energy the body takes from the internal organs. After such trainings need to restore the body within three days. Continue reading
