The role of pre-exercise activities

Sports should be familiar to everyone. No matter what age group you are in, you should do appropriate exercise. Even the elderly should do some exercise regularly in their daily life, because exercise plays an irreplaceable role in life. However, there is one thing we need to pay attention to before exercising, that is necessary activities. We must know that pre-exercise activities play an indispensable role in exercise and health. So, what are the specific effects of pre-exercise activities? Let us learn about it together.

The main functions of pre-exercise activities are as follows:

1. Adjust the overall status

Warm-up exercises can increase the excitability of the central nervous system, regulate poor pre-game conditions, speed up brain reactions, and coordinate participating motor centers, thus preparing for the rapid achievement of appropriate physiological functions during formal practice or competition.

2. To overcome the physiological inertia of internal organs

Warm-up exercises can improve the functional levels of the cardiovascular and respiratory systems, increase pulmonary ventilation and cardiac output, dilate the capillary network of the heart and skeletal muscles, and enable working muscles to obtain more oxygen. This can overcome the physiological inertia of internal organs and shorten the time it takes to enter working mode.

3. Improve the body's metabolic level and increase body temperature

Increased body temperature can reduce muscle viscosity, increase muscle contraction and relaxation speed, and increase muscle strength; when the body temperature is high, hemoglobin and myoglobin can release more oxygen, increasing the oxygen supply to the muscles; increased body temperature can increase the activity of enzymes in the body, improve the level of material metabolism, and ensure a more sufficient energy supply during exercise; increased body temperature can also increase the excitability of the central nervous system and muscle tissue; at the same time, increased body temperature increases the extensibility, flexibility and elasticity of muscles, thereby preventing sports injuries.

4. Increasing blood flow to the skin is beneficial for heat dissipation

Now that we have understood the role of pre-exercise activities, we must ensure in our future lives that no matter what sport we do, we must do the corresponding warm-up activities before exercise. This is unavoidable and irreplaceable. Only if we do the necessary activities before exercise can we ensure the completeness of the exercise and effectively avoid the occurrence of unnecessary sports injuries.
