The principle of physical exercise is the reflection of the objective law of physical exercise, and it is also the basic criterion that participants must follow when arranging exercise plans, choosing exercise contents and using exercise methods. The following five principles are people's experience in physical exercise practice and provide scientific guidance for exercisers to achieve ideal results. First, the principle of conscious enthusiasm The principle of conscious enthusiasm means that physical exercisers have clear fitness goals, fully realize the value of physical exercise, and consciously and actively engage in physical exercise activities. Physical exercise is a process of self-exercise and self-improvement, which needs to overcome its own inertia and various difficulties. At the same time, it is necessary to have a certain work and rest system as a guarantee and take physical exercise as an indispensable part of life in order to be effective. How to improve the conscious enthusiasm of physical exercise? (1) Make clear the scientific truth that "life lies in exercise", establish the correct purpose of exercise, regard physical exercise as the conscious need of daily study and life, and stimulate the initiative of exercise, thus mobilizing the enthusiasm of exercise. (2) Cultivate interest, which is people's tendency to know things and engage in activities. When a person is interested in a sports activity, he will show great initiative and consciousness in this sports activity, so as to achieve the integration of body and mind. Second, the principle of stressing practical results. The principle of stressing practical results means that when choosing exercise content, methods and arranging exercise load, it should be determined according to the individual's gender, age, occupation, health status, hobbies, requirements, the original basis of exercise and living conditions, and exercise according to scientific methods to achieve the best exercise effect. How to stress practical results in physical exercise? (a) according to the individual's actual situation, formulate a set of feasible exercise plan or exercise prescription, and strictly implement it, pay attention to the phased adjustment. (2) When choosing exercise content, we should pay attention to its fitness value, do not pursue the form of action, do not engage in difficult technical action training beyond our ability, and choose physical exercise that is simple, practical, valuable and effective as the main content of physical exercise. (3) When arranging the exercise load, it should be based on the difficulty that the exerciser can bear and overcome, and generally feel comfortable and will not affect the normal study, work and life (see the value threshold theory of exercise load for the measurement standard). Third, the principle of perseverance The principle of perseverance means that physical exercise must be carried out regularly, making it an important part of daily life. Physical exercise stimulates the body, and each stimulation produces certain traces of action, while continuous stimulation produces traces of accumulation. This accumulation makes the structure and function of the body adapt to the new situation, the physique will continue to strengthen, and the conditioned reflex of motor skills will continue to strengthen. Therefore, it is very important to insist on physical exercise. It is impossible to expect to achieve remarkable results in a short time, and it must be accumulated for a long time. How can we make physical exercise persistent? (1) According to your own ability, set an achievable physical exercise goal (not too high) and make a practical exercise plan (which can be adhered to for a long time). (2) Strengthen exercise awareness, list physical exercise as the content 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. (3) The effect of physical exercise is not permanent. If the interval between exercises is too long, the effect will not be obvious. Therefore, every time you exercise, you must insist on arranging a reasonable exercise interval. Fourth, the principle of gradual progress The principle of gradual progress means that physical exercise must follow the basic laws of the natural development of the human body and the adaptation of the body, reasonably arrange the exercise load from different subjective and objective realities, and gradually improve the exercise level. In the process of physical exercise, the magnitude of exercise load directly affects the change of human function, and whether the load is appropriate plays a great role in the quality of exercise effect. The magnitude of exercise load varies from person to person and from time to time. Even the same person, in different functional States and at different times, the human body's ability to bear the load is different. Therefore, physical exercise should be gradual, adjust the exercise load at any time, and gradually improve the level of exercise. How to implement the principle of gradual progress? (1) Physical exercise should not be rushed. According to the actual situation of exercisers, we should determine the size of exercise load and do what we can, especially pay attention to the moderation of fatigue after exercise. (2) The exercise load should increase gradually from small to large. When starting to engage in physical exercise or resuming exercise after interrupting physical exercise, the intensity should be small, the time should be short and the density should be appropriate. (3) Pay attention to improving the exercise load that the human body has adapted to, so as to keep the trend of physical fitness enhancement. Generally speaking, we should gradually increase the intensity of exercise on the basis of gradually increasing the "quantity" to adapt it to the pleasure of competence, and then make corresponding adjustments. Strengthen self-supervision at any time and pay close attention to the adverse reactions of physical function. (4) Pay attention to the warm-up activities at the beginning of the exercise; After the exercise, relax and tidy up. (5) People who lack a certain physical exercise foundation, or those who have interrupted physical exercise for too long, should not participate in fierce competition activities. Five, the principle of comprehensiveness The principle of comprehensiveness means that physical exercise must pursue the all-round and harmonious development of body and mind, so that the physical form, function, physical quality and psychological quality can develop in an all-round and harmonious way. The human body is a whole composed of all parts, and all parts develop according to the law of "using in and discarding out". Physical exercise can promote the general exuberance of metabolism, coordinate the development of various systems, tissues and organs of the body, and achieve relative perfection and perfection of the body. How can I do comprehensive exercise? (1) All-round physical and mental development should focus on the ability to adapt to the environment, resist diseases, improve body shape, improve body function, cultivate mood and enrich cultural life. (2) The contents and methods of physical exercise should consider the all-round development of the body as much as possible. Generally speaking, some effective and interesting sports are the main ones, supplemented by other sports. (3) Pay attention to the activities of the whole body, not limited to local areas. (4) On the basis of comprehensive exercise, strengthen professional and practical physical exercise purposefully and consciously. The above principles are interrelated, and in practical application, we cannot lose sight of one thing and lose sight of another. References:
