Knee pads have three functions, one is braking, the other is heat preservation, and the third is health care. Not much to say about heat preservation. The knee is very easy to catch cold. Many knee joint diseases are related to cold knees, especially in the mountains. The mountain wind is very cold and hard. Often the leg muscles will feel very hard due to constant exercise. The knee is not hot because there is no muscle movement, so when people feel that the leg heat is very comfortable, the knee is actually getting cold. At this time, if you are wearing a knee pad, the insulation effect of the knee pad can be reflected. .
Mainly talk about the braking effect of knee pads. The knee joint is where the upper and lower leg bones meet. There is a meniscus in the middle and a patella on the front. The patella is stretched by two muscles, suspended before the junction of the leg bones. It is very easy to slide. In normal life, it is not subject to external force. It is affected, and there is no strenuous exercise, so the patella can move normally in a small range in the knee area. Because mountaineering exerts too much pressure on the knee, coupled with the strenuous exercise in mountaineering, it is easy to cause the patella to be retracted away from the original position, thereby causing knee joint diseases. Wearing a knee pad can fix the patella in a relatively stable position to ensure that it is not easily injured. The above is the mild braking effect of the knee brace when the knee joint is not injured. After the knee joint is injured, the knee brace with heavy braking can reduce the bending of the knee, maintain a straight line from the thigh to the calf, and reduce the knee joint. Bend to protect the knee joint from aggravating the condition.
