Exercise for health preservation

Modern research holds that exercise is a characteristic of life's existence, and every cell in the human body is constantly in motion. Reasonable exercise can improve the functions of various systems in the human body and is an important means of strengthening the body and maintaining health. Exercise can enhance cardiovascular function, dilate the coronary arteries that nourish the heart, and improve the blood supply to the heart. It increases the elasticity of blood vessels throughout the body and enhances heart function. Exercise can also improve the respiratory function of the human body and enhance the function of the digestive system. It can also boost the function of the nervous system, making people's minds clear, their hearing and vision sharp, their movements flexible, their thinking quick, their energy flowing, and slow down the aging process of brain cells. Therefore, it can also be said that exercise is a major magic weapon for health preservation and fitness. The principles of exercise for health preservation (1) : Master the amount of exercise well and keep it moderate without getting tired. Exercise for health preservation aims to achieve the goal of health preservation and longevity through physical activity. Therefore, it is important to pay attention to the amount of exercise, especially for those with poor physical conditions. If the amount of exercise is too small, the purpose of exercise cannot be achieved and the fitness effect cannot be realized. If the amount of exercise is too much, it may exceed the body's tolerance level and instead cause damage to the body due to excessive fatigue. Sun Simiao pointed out in his "Thousand Gold Prescriptions" : "The way of health preservation is to always seek light labor, but not excessive fatigue or force." Therefore, exercise for health preservation emphasizes moderation without fatigue, gradual progress, and not being overly eager for quick success. Being too hasty often leads to desiring speed but failing to achieve it. At present, the amount of exercise is mostly determined by the speed of heart rate. The method is to measure the heart rate at the peak of the exercise. First, measure the heart rate for 10 seconds, then multiply it by 6, and the result is the heart rate per minute. The difference between 176 and age is the appropriate heart rate during exercise. If the heart rate is lower than the appropriate level, the amount of exercise should be increased; if it is higher than the appropriate level, the amount of exercise should be reduced. (2) The key lies in persistence. Exercise for health preservation is not something that can be achieved overnight. The key lies in maintaining it consistently and without interruption. The saying "Running water never goes bad, and a door hinge never rots" on the one hand explains the principle that "movement never fades", and on the other hand emphasizes the importance of persistence and continuity. Only when water flows constantly can it not go bad; only when the pivot of a household keeps turning can it not be eaten by insects. Only by persistently and unremittingly engaging in appropriate exercise can one achieve the effect of health preservation and fitness. However, working hard for three days and then slacking off for two will not reach the goal of fitness. Exercise for health preservation is not only about physical training, but also about the cultivation of willpower and perseverance. (3) There should be a balance between tension and relaxation. Exercise for health preservation does not mean continuous and prolonged physical activity. Instead, it requires a balance between work and rest, as well as tension and relaxation, in order to achieve the goal of health preservation. Therefore, intense and vigorous exercise should be alternated with relaxation, breathing regulation and other rest exercises. When exercising for a long time, it is important to take appropriate breaks. Otherwise, it can affect work efficiency, make the exercise uncoordinated, dampen one's spirits, and even be detrimental to health preservation and fitness.
