1. Knee injury due to sedentary

How many people feel that running hurts their knees?

Among the average runner, 3.5% had arthritis of the knee or hip.

Among the sedentary non runners, 10.2% had arthritis of the knee or hip.

Among professional competitive runners, the incidence of knee or hip arthritis was higher, 13.3%.

Yes, sedentary is more damaging than running.

Just like a car, if you don'   t use it for a long time, its parts will simply rust.

Similarly, human joints always do not move, the synovial fluid in the joints can not flow fully, and can not play the role of a smoother. The surrounding muscle tissue is shrinking day by day, which will greatly increase the risk of joint injury.

Sedentary people, we must pay attention to it!!!

2. Sitting cross legged

How many people, as soon as they get home, will sit cross legged on the sofa watching TV.

When people sit with their feet crossed, the knee joint is in a flexion state. Due to the effect of gravity, the knee joint will accept the sinking force, resulting in the uneven stress on the inside and outside. In a short time, the knee joint is simply deformed.

If you can'   t help but cross your legs, you can only bend one leg at a time, which can reduce the knee injury caused by cross legging to a certain extent.

3. Long time squatting

How many people, in working hours, will squat while brushing their mobile phones while relaxing.

However, how many people realize that the squatting posture is actually an advanced version of squatting. Especially when the squatting position is more than 90 degrees, the kneading of the medial knee joint will become larger, which will form the wear of the medial patella.

So, when squatting, try to put down your mobile phone and make a quick decision.

4. Wear high heels

I do not know when, women will be very naturally put on high heels to work.

But how many people have noticed that when you put on high-heeled shoes, the center of gravity will move forward, and the pressure will increase from toes to calves to knee joints, which will easily lead to a series of hazards such as "thumb valgus", knee joint wear and low back muscle strain.

So, if you don'   t need occasion, women don'   t wear high heels.

5. Jump rope on a solid floor

Summer is coming, people'   s desire to lose weight is becoming more and more intense.

There are many people will want to jump rope weight loss, but jump rope specific to choose in the plastic track or community sports ground and other specific buffer.

As a result of the movement on a solid floor, in a strong reaction force bounce back, the joint and bone damage is considerable.

6. Climbing mountains and stairs

Many orthopedic experts say: mountain climbing is a stupid sport.

Because the knee in climbing, the pressure is three times the weight;    When you go down the mountain, you'   re under four times your weight. And the faster the speed, the greater the pressure on the knee.

To make matters worse, the damage to the knee caused by mountain climbing is irreversible.

If you really want to climb a mountain, you must first do gentle muscle strength exercises. When climbing a mountain, try to be slow and slow.
