Sleep can repair tissues such as muscles and promote cell metabolism. I have made it very clear, so I won't gild the lily. Sleep can reduce energy consumption. For bodybuilders, physical growth is the ultimate goal, so energy storage is the most important in leisure. Dinner in a day can also promote muscle growth, and sleep helps to ensure that food is used to replace energy and restore muscles, so it is generally recommended to eat more meals and snacks before going to bed. Sleep can replenish energy to the brain. Lack of sleep will affect mood, make people irritable, impatient and persistent, and reduce the will to overcome difficulties. These unhealthy mentality will often limit the normal exertion of exercise state, make bodybuilders feel anxious and discouraged, and affect the exercise effect and the formation of fitness habits. Therefore, a good sleep can make the brain get a full rest and make the physical and mental state reach the best. In addition, some people will suffer from insomnia after fitness. After fitness, they sweat, take a hot bath and have a good sleep. This feeling is really good. But some people can't sleep after exercise. As soon as they lie down, the shadow of crazy movement runs at high speed in their minds and can't be thrown away over and over again. There may be two reasons for insomnia after fitness: first, the interval between exercise and sleep is too short; Second, the amount of exercise and intensity is too great to sleep. Gymnasts in this situation are very sensitive to the excitement of sports, so they should adjust their plans and prepare to fall asleep 4 hours after the end of fitness, so that the excitement has subsided when they fall asleep. ? In addition, don't choose particularly intense sports, such as spinning, because the explosive concert is too exciting. Try to choose aerobic exercise, brisk walking, yoga and so on. And don't exercise too much.
