First, the disadvantages of walking People with weak cardiopulmonary function are easy to induce angina pectoris and myocardial ischemia, so such people must reduce their exercise intensity at a certain stage. In addition, obese people themselves do not exercise, and it is easy to hurt their knees when they suddenly exercise with their feet. We should choose a step-by-step approach. Long-term walking is not good for the elderly, and physical overwork can lead to muscle fatigue and varicose veins of lower limbs. Old people are prone to muscle strain when walking for a long time, which will also affect human internal organs. In addition, the bones of the elderly become soft and their balance ability decreases. They are more likely to fall down after walking for a long time, and their physical strength will faint tirelessly, which is prone to accidents. Long-term walking in the elderly will cause knee injury.
Second, the precautions when walking, walk on the sidewalk. If there is no sidewalk, you should take the side of the road. For sections with overpasses and underpasses, you should take them yourself. When preschool children are walking, adults should always pay attention to the road conditions when leading the way. Always check the provisions of traffic signs, road signs and signs, pass through the guardrails of sidewalks, lanes and railway passages, and do not block the vehicles on the road.
It can be seen that walking has the advantages of accelerating metabolism, improving immunity, improving body resistance and reducing the risk of illness, but it also has an inseparable impact on the elderly. In addition, it is not recommended to walk on asphalt, because asphalt is hard and has a great influence on knees. There are cars on the road, which is unsafe, and the automobile exhaust is not friendly to the respiratory system.
