Exercise prescription is different from ordinary physical exercise and general treatment. Exercise prescription is a highly targeted, purposeful, selective and controllable exercise therapy. The physiological functions of exercise prescription mainly include the following aspects, which can effectively promote people's health.

Influence of Exercise Prescription on Cardiovascular System

Exercise prescription is mainly endurance exercise with moderate intensity aerobic metabolism, that is, aerobic exercise. Generally speaking, aerobic exercise plays an obvious role in enhancing the oxygen transport capacity of cardiovascular system, eliminating metabolites, regulating the oxygen uptake of working muscles and the ability of tissue to utilize oxygen. Exercise according to exercise prescription can slow down the heart rate, stabilize blood pressure, increase cardiac output and enhance the compensatory ability of cardiovascular system. However, we should be cautious in the case of heart disease, such as congenital aortic stenosis, which is common in children. It is easy to get tired after exercise and the aerobic exercise ability is reduced. If you exercise reluctantly, you can have fainting, chest pain, and a few even die suddenly.

Effect of exercise prescription on respiratory system

Implementing exercise prescription can enhance the ventilation and oxygen uptake ability of respiratory system and improve the functional state of respiratory system.

Influence of exercise prescription on exercise system

Implementing exercise prescription can enhance muscle strength, muscle endurance and muscle coordination to maintain and restore joint range of motion, promote bone growth, stimulate proprioceptors, preserve exercise conditioned reflex, promote blood and lymphatic circulation of exercise system, and eliminate swelling and pain.

Effect of Exercise Prescription on Digestive System

Exercise prescription can promote the function of digestive system, strengthen the absorption and utilization of nutrients, stimulate appetite, promote the synthesis and excretion of bile, reduce the occurrence of gallstones, promote gastrointestinal peristalsis, and prevent and treat constipation and other diseases.

Effect of exercise prescription on nervous system

Implementing exercise prescription can improve the excitement or inhibition ability of central nervous system, improve the regulation function of cerebral cortex and neurohumors, and improve the functional regulation of nervous system to various organs and systems.

Effect on body fat

Exercise prescription with long exercise time and moderate exercise intensity can effectively reduce adipose tissue and achieve the purpose of disease prevention and fitness.

Effect of exercise prescription on compensatory function

When limb function is lost due to various injuries, the human body produces various compensatory functions to make up for the lost function. Some compensatory functions can be formed spontaneously. For example, after one kidney is removed, the excretory function of the body is assumed by the opposite kidney. However, some compensation functions require guided training or hard training to produce the required functions. For example, after limb deformity, replace the function of the affected limb with a healthy limb. Exercise prescription plays an important role in promoting the establishment of compensatory function.

Influence of exercise prescription on people's psychology

Exercise can effectively release depressed emotions, enhance psychological endurance and maintain psychological balance. In the process of treatment and rehabilitation of diseases, it can enhance patients' confidence in treatment and rehabilitation and contribute to the rehabilitation of diseases; Exercise according to the exercise prescription of prevention, fitness and bodybuilding can keep a good mood and make work and study more active and relaxed.

The concept of physical fitness.

Physical Fitness is the Chinese translation of physical fitness, which means that the human body has enough energy to engage in daily work (study) without feeling tired, and can spare no effort to enjoy leisure activities and adapt to unexpected situations. The American Sports Medicine Association believes that physical fitness consists of healthy physical fitness and skilled physical fitness. Healthy physical quality is closely related to health, which refers to the ability of cardiovascular, lung and muscle to exert their best efficiency.

The American Sports Medicine Association believes that physical fitness includes "healthy physical fitness" and "skilled physical fitness".

The main contents of healthy physical fitness are as follows:

① Body composition: that is, the percentage of various components in the human body. Keeping the body composition in the normal percentage range is of great significance for preventing some chronic diseases such as diabetes, hypertension and arteriosclerosis.

② Muscle strength and endurance: Muscle strength is the maximum strength that muscle can produce, and muscle endurance is the ability of muscle to contract continuously, which is the basis of normal work of the body.

③ Cardiopulmonary endurance: Also known as aerobic endurance, it is the basis of the body's long-term work and is considered to be the most important factor of healthy physique.

(4) Flexibility: the maximum range of finger joint movement, and no pain. It is of great significance for maintaining human sports ability and preventing sports injuries.

Skill physical fitness, including agility, balance, coordination, speed, explosiveness and reaction time, is the basis of engaging in various sports, but there is no evidence that it is directly related to health and disease.

"Physical fitness" can be regarded as the comprehensive ability of the body to adapt to life, exercise and environment. People with good physical fitness, engaged in physical activities or sports in daily life or work, have better vitality and adaptability, and will not easily feel tired or overwhelmed. In a civilized society with scientific and technological progress, there are fewer and fewer opportunities for human physical activities, higher and higher nutrition intake, and relatively increased work and life pressure and leisure time. Everyone feels the importance of good physical fitness and regular exercise. In terms of measurement, physical fitness can be divided into three aspects: cardiopulmonary fitness, muscle fitness and weight control.
