As people get older, not only do the musculoskeletons age and the nervous system degenerates, so it's easy to get up and down the stairs. The old human body is poorer, and the elasticity of muscles and ligaments is not as good as that of young adults. It is difficult to control the condition slightly. For example, on a 20-centimeter step, the step taken by the old man may not have been raised enough, and the nervous system responsible for commanding movements has already issued a "going out of the next step" order. At this time, it is prone to falls. If conditions allow, older people try to reduce the number of stairs up and down. However, when you must go upstairs and downstairs, you must master certain skills: Ning rather than straight, rather slow and not fast.
Don't be straight. From a physics standpoint, walking up a stairway diagonally increases the pace, while the magnitude of the increase does not change (each step is fixed), and the increase in the step size per unit is relatively small, so the effort can be achieved. In addition, on the side of the slope, the slope is gentle, and the force that the human body uses to maintain the body's balance (not to fall) is much less, and it can feel relaxed and effortless.
Rather slow, not fast. Slow words are almost the main theme in the lives of older people, and walking stairs is more healthy. First of all, the elderly are limited in physical strength, and strenuous exercise tends to exacerbate the burden on the heart and have the risk of accidents. In addition, the elderly responded slowly and the central control was poor. For example, he obviously wanted to put his feet on the steps of the stairs. He could only put his feet in the air. When he realized that the situation was not right, he could not timely correct. Slow motion can effectively avoid the above risks. Do not step up the stairs and wait for your feet to be on a single step. Then take the next step and reduce the weight of the joints. This is especially important for osteoporotic old people and can greatly reduce the fall. And the chance of a fracture.
Sideways downstairs. Going downstairs, people's bodies are almost vertical and they easily fall over. Sideways downstairs, the body has a slope, in case of dizziness, misjudgment and other accidents, can have a full response time. Even if an accident occurs, the damage can be avoided or reduced.
