The autumn is crisp and the scenery is pleasant. In traditional festivals in China, such as the Double Ninth Festival, many elderly people like to climb high and look far, which can broaden their horizons, strengthen their bodies and refresh themselves, strengthen their brains and improve their respiratory function.
Autumn is a good time to exercise, but elderly people who are weak and recovering from illness should not do such activities, such as those with cardiovascular diseases, dizziness, chest tightness and palpitations.
In the cold winter, from the warm room to the outdoor, the body often gets cold. According to the measurement, the skin temperature of the elderly who insist on winter training can return to normal in about five minutes after encountering cold air. For the elderly who have no exercise habits, it takes ten to twelve minutes. It can be seen that outdoor sports in winter are not suitable for all the elderly. However, if we don't pay attention to the health knowledge of winter sports, outdoor sports will not adapt to or bring harm to the body.
Therefore, the elderly who exercise outdoors should be fully prepared before exercise, so as to improve the excitability of cerebral cortex to an adaptive state, promote the expansion of capillaries in muscles, increase blood supply to muscles, improve muscle strength, elasticity and joint flexibility, and prevent muscle and ligament injuries. After exercise, we should do a good job of finishing activities, so that each system of the body gradually changes from active state to quiet state, thus achieving the effect of eliminating fatigue.
