There is almost no exercise that won't hurt your knees, because as long as you move, there will be friction, and there will be damage if there is friction. The damage to the knee caused by daily walking is still relatively small. If people who exercise regularly do not pay attention to protecting their knees, they are likely to lead to premature aging of their knees. How helpless it is to offer a pair of knees in advance when you only want the vest line.

So, which sports do the most harm to the knee?

The five common exercises listed below are all harmful to the knees.

1, mountaineering

When a person climbs a mountain, his knees not only bear the weight of his body, but also climb hard. When climbing a mountain, the weight borne by the knees is about four times that of standing upright. The more the load, the faster the speed, and the greater the pressure on the knee. Therefore, it is necessary for people who often climb outdoors to prepare a trekking pole.

2. Badminton, basketball, football, etc.

Badminton, basketball, football and similar ball games have serious injuries to the knees. These ball games need a lot of flexible running, and often need to suddenly accelerate or stop, there are many fast twisting movements, as well as frequent jumps in basketball and so on. These dynamic and static transformations and explosive movements greatly enhance the friction between the knees and bring great pressure to the knees.

Step 3 run

People who like running may have heard of "runners' knees". When running, people use their legs for maximum strength. On the top, they have to bear the gravity of their bodies. On the bottom, they have to bear the impact when landing and the pedaling pressure when running. According to the test, the impact on the knee when landing on one leg is 2~4 times the weight. The longer the distance, the longer the time and the faster the speed, the greater the pressure and wear on the knee.

4. Aerobics

Aerobic exercise is also one of the knee killers, because aerobic exercise often has a lot of jumps or squats. Many people jump barefoot on the hard floor for convenience, which is more harmful to their knees. In recent years, due to the popularity of aerobics such as Duoyan Zheng and Crazy, many people need to treat knee injuries.

Step 5 jump rope

Jumping rope does much less harm to the knees than running, because most people don't jump for an hour or two. The main cause of knee injury caused by skipping rope is the stress caused by overweight of some people.
