Knee pad refers to an item used to protect people's knees. In modern sports, knee pads are widely used. Knee is not only an extremely important part in sports, but also a relatively fragile and easily injured part. It is also an extremely painful and slow recovery when injured, even someone else may feel dull pain when it rains and cloudy days. It can reduce and avoid injuries to a certain extent, and can also play a cold-proof role in winter.
Function:
1. Insulation: the knee part is very easy to catch cold. Many knee joint diseases are related to the cold of the knee, especially on the mountain, the mountain wind is very cold and hard, and often the leg muscles feel very hot due to the exercise, however, the knee is not hot because there is no muscle movement. When people feel that the leg is cooling comfortably, the knee is actually getting cold. At this time, if they wear knee pads, the heat preservation effect of knee pads can be reflected.
2. Brake: the knee joint is the place where the upper and lower leg bones meet. There is a menisci in the middle and a patella in the front. The patella is stretched by two muscles and is suspended before the leg bones meet. It is very easy to slide. In normal life, because it is not affected by external force and does not exercise violently, the patella can move in a small range normally in the knee. Because mountaineering puts too much pressure on the knees and the vigorous movement in mountaineering, it is easy for the patella to be pulled away from the original part. The kneecap can fix the patella in a relatively stable position to ensure that it is not easily injured.
