The relationship between physical exercise and nutrition? For example, physical exercise and nutrition.

Nutrition and physical activity are two important factors to maintain metabolism and promote human health. Nutrients are an important material basis for organizing and maintaining human life activities, and physical activity is an effective means to enhance human function. The scientific combination of the two can effectively enhance physical activity ability, improve health level and promote the improvement of sports performance. In physical exercise, a correct understanding of the main physiological functions and reasonable demands of nutrients needed by the human body and scientific and reasonable nutrition supplementation can obviously improve the physical exercise effect, improve physical function, enhance physical fitness, and play a good role in preventing diseases, improving health level and delaying aging.

With the progress of society and the continuous improvement of living standards, people pay more and more attention to physical health. From this famous saying, we realize the importance of exercise, which can promote health. Reasonable nutrition and physical exercise are good behaviors to promote health. While the nutrition supply is sufficient and balanced, proper exercise is beneficial to the growth and development of children and adolescents and the improvement of the health level of middle-aged and elderly people.

Sports nutrition directly changes people's physiological and psychological activities in a quiet state through physical exercise. Promote the functional systems of the body to enter an active state, thus accelerating the blood circulation of the whole body, making all organs in a highly excited and active state, and activating capillaries, alveoli, muscle fibers and nerve cells that have been closed for a long time as much as possible in a static state, thus obtaining sufficient oxygen and nutrition for the blood of all organs.

A healthy body, a good nervous system and functional systems of all parts are the physiological basis of people's psychological development and the material premise to ensure people's psychological health. Only by eating scientifically and reasonably can we meet the nutritional needs of the human body. Only by meeting reasonable nutritional needs can we promote the growth and development of college students, improve their health, make them energetic, physically strong and flexible, improve their work efficiency, enhance their disease resistance, delay aging, and thus improve their health as a whole.

With scientific and reasonable nutrition as the material basis and physical exercise as the means, the consumption process of exercise is exchanged for the excessive recovery process after exercise, so that the body can accumulate more energy substances and improve the functions of various organ systems. The health obtained at this time has risen to a new height compared with the health obtained solely by nutrition. Therefore, reasonable nutrition and physical exercise can not only get health, but also get good physical fitness.

Nutrition is closely related to sports, which has a great influence on sports effect. The energy consumption caused by physical exercise should be supplemented by a reasonable nutritious diet after exercise. If there is no reasonable nutritional guarantee and consumption is not supplemented, the body will be in a state of "loss". Over time, it is not good for health, it will reduce the physiological function and sports ability of the exerciser, and even lead to fatigue and even illness. Adequate nutritional supplements can effectively eliminate fatigue and promote physical recovery. The human body is often tired due to fierce competition, large-scale physical exercise or strong physical labor. In order to eliminate fatigue and improve symptoms in time, in addition to strengthening the finishing activities before and after and carrying out appropriate physical therapy, paying attention to the conditioning of diet and nutrition is an important part that can not be ignored in modern life. Intake of certain nutrients before and after exercise can not only delay the appearance and reduce the degree of fatigue, but also accelerate the elimination of fatigue.

For example:

My favorite sports are long-distance running and playing tennis. Long-distance running requires high cardiopulmonary function and anti-fatigue ability of the whole body. Although the intensity is small, it takes a long time and consumes a lot of energy. Playing tennis requires strength, speed, endurance, agility and flexibility. During long-distance running, the body mainly carries out aerobic metabolism of carbohydrates and mainly consumes starch. Therefore, after exercise, my appetite that day will be 1.5 times that of usual. When playing tennis, the body mainly relies on anaerobic metabolism of sugar to provide energy. When sugar undergoes anaerobic metabolism in the body, it will produce an acidic substance called lactic acid. The accumulation of this substance in the body will cause fatigue and prolong the recovery time. So for strenuous exercise, I will specially supplement some alkaline foods, such as vegetables and fruits. Of course, scrambled eggs with tomatoes in the canteen are also essential.
