Physical exercise is a physical activity aimed at developing the body, improving health, strengthening physique, regulating spirit and enriching cultural life.
Physical exercise is characterized by taking fitness as the main purpose, and the goal is to obtain the actual fitness effect. The form, content, methods and means of physical exercise follow the principle of being different from time to time, from place to place and from person to person, not sticking to one pattern, but according to everyone's specific situation, in accordance with the principles and methods of scientific physical exercise, combined with natural conditions.
Each exerciser should reasonably select and determine the content, method, exercise load and intensity according to his own situation, such as age, gender, occupation, health status, physical fitness level and living conditions. Even the same person, from teenagers to the elderly, has different interests, hobbies, ability to bear sports load and requirements for sports.
The principle of step by step and perseverance The adaptation of human body to changes in internal and external environment is a slow process from quantity to quality. Physical exercise must gradually adapt to higher requirements according to the law of natural development of human body and the principle of excessive recovery, and gradually achieve the purpose of strengthening physical fitness. When choosing the content and method of exercise, we should change from easy to difficult, from simple to complex, and the weekly exercise times, exercise time, exercise load and intensity should be gradually increased, so we can't rush headlong into it. Determine the next exercise plan according to your own self-feeling, test effect and sports performance.
The principle of suitable exercise load refers to the physiological burden that physical exercise bears on the human body. Exercise load is determined by two aspects: exercise intensity and exercise amount. Exercise intensity refers to the strength and body tension used to complete the exercise, including the speed of the action, the density of the exercise, the length of the interval of the exercise, the weight of the load, the distance of throwing, the height and distance of jumping, etc.
