Principles and methods of scientific physical exercise
1. When arranging the exercise load, the difficulty that the exerciser can bear and overcome, the general feeling of self-comfort and the normal study, work and life shall prevail (see the value threshold theory of exercise load for the measurement standard).

2. According to your own ability, establish an achievable physical exercise goal (not too high) and make a feasible exercise plan (which can be adhered to for a long time).

3. Strengthen exercise awareness, make physical exercise a part of daily life, regularly ensure a certain amount of physical exercise time, and gradually develop habits, so that physical exercise becomes an important part of life.

4, the effect of physical exercise is not once and for all, if the exercise interval is too long, the effect will not be obvious. Therefore, every time you exercise, you must insist on arranging a reasonable exercise interval.

The role of scientific exercise:

1, improve the body's functional adaptability.

When the internal and external environment changes in a certain range, the body can make appropriate responses to maintain its own survival and overcome the harm caused by these changes. Scientific exercise can stimulate the body, make the body's physiological activities undergo benign changes and improve the body's functional adaptability.

2. Improve the coordination ability of the body.

The vertical relationship between the functions of cells, tissues, organs and systems in the human body must be that the lower level obeys the higher level, and the coordination between systems must also obey the overall function of the individual. Scientific exercise can not only enhance the function of the exercise system, but also improve the obedience, coordination and physiological functions of various organs and systems.

3. Improve heart function

The characteristic of cardiac function activity is that it increases with the increase of exercise intensity and is at a low level when it is quiet. The greater the intensity of exercise, the higher the activity level, which can improve the heart function during the growth and development period, maintain the heart function after the development stops or slow down its attenuation rate.
