After physical exercise, how to eliminate fatigue as soon as possible and promote the recovery of physical function has attracted more and more attention from the majority of exercisers. This paper introduces several methods to eliminate fatigue. Laughing loudly can eliminate fatigue after exercise, because: first, increase the breathing ability of the lungs and clean the respiratory tract; Second, express healthy emotions and eliminate tension; Third, relaxing muscles helps to distribute excess energy; Fourth, dispel the haze and relieve all kinds of mental stress. Therefore, whenever you do physical exercise, you might as well open your throat and laugh heartily. There are two ways to have a reasonable rest after fatigue, static rest and active rest. Active rest is to eliminate fatigue by adjusting exercise load, changing exercise content and changing the activities of different sports parts during exercise. Relax by psychological means 1. Meditation: Under the guidance of consciousness, deliberately meditate on some words and phrases, and self-suggest muscle relaxation. You can say "I am relaxed all over", "I am completely relaxed and want to sleep ..." and other psychological adjustments when you sit still, close your eyes and breathe slowly and steadily. 2. Breathing counting method: when breathing, one breath is inhaled as one breath. Relaxators should silently count their own breaths, constantly count them, make their consciousness focus on the number of breaths, and deliberately exclude the invasion of other distractions, so as to stabilize their emotions, concentrate their consciousness and relax their bodies. 3. Intention to defend oneself outside the law: that is, to defend oneself outside things. The content of observation should make people feel calm, relaxed and happy, or observe and recall beautiful things in kind, such as walking around the moon, quiet environment, gurgling streams and so on. Strengthening sleep with reasonable sleep effect can not only avoid the functional failure caused by excessive consumption of nerve cells, but also restore the normal function of tired nerve cells. Anabolic metabolism is greater than catabolic metabolism during sleep, which contributes to the recovery of physical strength and spirit and is very important to people's health, especially the health of the human brain. What kind of sleep effect is reasonable? Generally speaking, feeling tired, comfortable, clear-headed and energetic after sleep can be considered as reasonable and effective sleep. Therefore, exercisers should arrange their own work and rest time reasonably and pay attention to sleep hygiene. Reasonable nutritional supplement First of all, the food mix after exercise should be reasonable to avoid partial eclipse. When sweating, you should supplement water or sports drinks containing sugar and salt. Secondly, pay attention to the pH of food. Acidic food will increase acidic substances in the body, reduce the alkali reserve in the blood, which is not conducive to activities and the body is prone to fatigue. Alkaline food is the opposite. Therefore, people who exercise regularly should not eat more acidic foods, but should eat more alkaline foods and pay attention to the acid-base balance of food. Thirdly, the cooking and processing of food should not only make food easy to digest, but also avoid nutrient loss, and pay attention to the color, aroma and taste of food to stimulate appetite. Massage on the load area can be done after exercise, or after taking a bath or before going to bed at night. The part of massage depends on the degree of exercise and fatigue of the exerciser, which is generally the part with the greatest massage load. Generally speaking, the massage method is 1. Kneading is the main part of joints. Start with a few nudges, then alternately knead and push, sometimes press, and finally end with a nudge. 2. Muscles are mainly kneaded. Kneading should account for 60 ~ 70% of the total massage time. Similarly, it starts with a nudge, then it is alternately pushed, pressed, slapped and shaken, and finally it ends with a nudge and shaking. 3. When massaging limbs, massage large muscle groups first, and then massage small muscle groups. In addition, various recreational activities and light music with moderate volume also have a good effect on eliminating fatigue.
