"the king of aerobic metabolism." when walking on a concrete road, it would be preferable to wear thicker geled shoes to prevent damage to the leg joint and concussion of the head. (3) for persons over 40 years of age, exercise may take place once a day or another day; maximum speed shall be limited to 100 metres per minute (approximately the rate of rush through the intersection). Attention: (1) the correct pace of physical exercise is much larger than the normal walk, the upper body is good, the arms are swinging back and forth, the breathing is natural, attention is focused, speeds and distances are increasing or increasing. In order to provide a reference, in general, the results of motor medicine studies suggest that walking speed is 133 metres per minute (about 7 km/hour, with a heart rate of 70 per cent of the maximum heart rate). But at what speed? It is difficult to generalize on this issue as long as it is considered appropriate. The common saying is, “one hundred steps after dinner and 99 lives”. Several more popular and age-appropriate fitness prescriptions are described below. Aerobics can provide adequate oxygen for active muscle groups, thereby effectively improving the function of the air-body respiratory system, promoting adaptive changes in the heart, lungs and blood; and effectively improving the body's ability to absorb and use oxygen, improving its defences and resistance and enhancing its body's physical integrity. The simple, easy-to-work physical exercise prescriptions, which are less skill-intensive, of low intensity, rhythm, duration and self-censorship in sports, are among the best ways to improve physical health and health based on safety. The walking exercise prescription “to be a great ancestor” is one of the easiest and most efficient ways to exercise and to extend life. It is clear that people have long known the value of walking. The exercise and exercise of fitness can be controlled according to their state of health, physical strength and exercise habits. It's the best aerobics, the best for fitness. (2) the duration of each walk shall be maintained for at least 30 minutes, and a piecemeal accumulation shall not be sufficient to give rise to an incentive for physical enhancement. (4) it would be preferable to choose a suitable place where the air is fresh and the environment is elegant. (5) it is not useful to walk immediately after dinner, preferably in the morning, before bed or after half an hour. Jogging has a positive effect on maintaining good heart function for adults, preventing elasticity of lung tissue, preventing muscle atrophy, combating coronary heart disease, hypertension, artery sclerosis, etc. Objectively no more than 180 minus age per minute per jogging.
