First of all, the least influential movement:

1, the exercise that has the least influence on masculinity should be running, well, because in the process of running, if it is a correct exam, it will have little influence on the knees, well, because, well, in the correct knowledge of running, his posture is, well, taking small steps as far as possible without stopping running, which will reduce the pressure on the knees, so it will have little influence on the knees, while skipping rope belongs to the exercise of the knees and calves.

2. It's skipping rope. Skipping rope is harmful to the knees and is not recommended as a regular exercise. If you want to jump rope, you must jump rope in a correct and reasonable way, control the amount of exercise, and minimize the damage to your knees. Jumping rope is not recommended for patients with knee joint injury and patients with cardiopulmonary diseases and cardiovascular and cerebrovascular diseases. The correct way of skipping rope is: when skipping rope, you should choose a flat and slightly soft ground to avoid possible injuries when skipping rope on a hard slate or concrete floor; Need to warm up before skipping rope;

Skipping rope and running are both good choices for human health. Skipping rope has a great influence on the knee joint, which may cause knee joint injury during skipping. The damage to the knee joint during running is relatively small, especially the impact of jogging on the knee joint is relatively small. As for choosing running or skipping rope, you should choose according to your physical condition. If you have knee problems, you can jog instead of running or jump rope quickly.

Second, sports suitable for the public:

1, running, as a means for modern people to exercise, keep fit or lose weight, is increasingly loved by the broad masses of the people. Generally speaking, running itself is unlikely to cause serious knee injuries, because it is not competitive running. However, the running of competitive sports needs long-term exercise, and the outbreak of all forces in a short time makes the stress on the knee joint exceed the stress that normal physiology can bear, which is harmful to the knee.

2. So race walking or long-distance marathon is harmful to the knee joint. However, ordinary exercise will not damage the knee joint, but may stimulate synovial fluid secretion and normal cartilage metabolism of the knee joint, which is good for the knee joint. So it is wrong to think that regular running is harmful to the knee joint. However, there are many other exercise methods, such as weight-bearing squats in the gym and lower limb exercises, which make the knee joint over 90 degrees and cause serious damage to the knee joint, so this exercise method is not recommended.

Third, the wrong way to exercise:

1, some people regard going up and down stairs as knee joint exercise or physical exercise, which is absolutely wrong. Because when going up and down the stairs, the knee joint must bend more than 90 degrees, and the weight of the load is more than 3 times the weight, so the damage to the knee joint is great. Skipping rope is also harmful to the knee joint, because unlike running, skipping rope is actually a vertical impact, which has an impact on the cartilage surface of the knee joint. So, don't do too much when skipping rope.

2. Environmental aspects. Running is basically carried out outdoors, so it is greatly influenced by temperature, terrain and climate, and it also has great requirements for the adaptability of human knees. In the case of poor knee adaptability, running may damage the knee. Skipping rope is basically done indoors, so it is less affected by the environment and less harmful to the knees.

3. difficulty. Running is difficult, which requires high knee strength and muscle coordination. In addition, running needs the strength of one leg to bear the huge impact of its own weight, speed and inertia. If one leg has insufficient endurance, both running and jogging will cause damage to the knee. The difficulty of skipping rope mainly lies in the coordination of hands and feet, so it is less difficult. Because of the coordination between the opponent and the foot, skipping rope often can't last for a long time, so it hurts the knee less.
