The principle of gradual progress is very important. The implementation of this principle can prevent the adverse effects caused by participating in physical exercise. The amount and intensity of exercise are from small to large, the time is from short to long, and the movement is from easy to difficult, and it cannot exceed the physical condition. After taking part in the exercise, the spirit and physical strength are good, and the appetite and sleep are normal, indicating that the amount of exercise is just moderate.
If you are depressed, exhausted, upset and have a bad sleep because of participating in physical exercise, it may be that you have exercised too much. Diversification means exercising all kinds of physical qualities.
There are four main physical qualities: strength, speed, endurance and flexibility.
Other physical qualities include: speed endurance, balance, directional coordination, adaptability and so on.
Adaptability also includes cold and hot adaptation, hunger and satiety adaptation, plateau adaptation, water and soil adaptation, bump adaptation, thirst and ultraviolet adaptation, etc. The four basic physical qualities, strength, speed, endurance and flexibility, have different exercise requirements with the growth of age.
Individualized treatment of different individuals has differences in physical strength, sports foundation and health status, and should be treated according to each individual's specific situation. Patients with coronary heart disease should focus on periodic exercise, such as walking, brisk walking or jogging. Patients with emphysema should do more breathing gymnastics and exercise expiratory function. People with sagging internal organs and loose abdominal wall should give priority to abdominal muscle exercise.
Pay attention to hygiene, and participate in physical exercise must conform to the hygiene principle, otherwise it will have a negative impact on health. It is obviously not in line with the hygienic requirements to take part in more intense physical activities immediately after meals, because gastrointestinal peristalsis slows down, digestive juice secretion decreases, blood supply to the digestive system decreases, and most of the blood is supplied to skeletal muscles, which hinders digestion. At the same time, put heavy food into your stomach. When exercising, especially when jumping, the burden on the stomach is particularly heavy, and there is a feeling of falling. Sweating in summer means jumping into the water to swim. You may feel very happy at that time, but you are vulnerable to water and moisture because your pores are open when you sweat.
Exercise is closely related to health and longevity. But physical exercise should pay attention to science in order to get good results, otherwise accidents will happen.
