A knee pad is an item used to protect people's knees. It has the functions of sports protection, cold protection, and joint maintenance. It is divided into sports knee pads and health knee pads. Suitable for athletes, middle-aged and elderly people, and patients with knee diseases.
In modern sports, the use of knee pads is very extensive. The knee is not only an extremely important part in sports, but also a relatively fragile and easily injured part. It is also extremely painful and slow to recover when injured. Some people even experience dull pain on rainy and cloudy days. The thick felt "knee pads" that can be bought in almost all sporting goods stores can reduce and avoid injuries to a certain extent, and can also play a role in preventing cold in winter, and the price is not expensive. This is not to recommend "knee pads" as a must-have, but it is true that they are widely used in all sports! There are three functions of knee pads, one is braking, the other is heat preservation, and the third is health care. Not much to say about insulation, the knee is very easy to catch cold, many knee joint diseases are related to the cold knee, especially in the mountains, the mountain wind is very cold and very hard, often the leg muscles will feel very cold due to the constant exercise. It is hot, but the knees are not hot because there is no muscle movement. When people feel that the legs are very comfortable to dissipate heat, the knees are actually cold. At this time, if you wear knee pads, the thermal insulation effect of the knee pads can be reflected. .
Mainly talk about the braking effect of the knee pads. The knee joint is the place where the upper and lower leg bones meet, with the meniscus in the middle and the patella in the front. The patella is stretched by two muscles and suspended before the junction of the leg bones. It is very easy to slide. In normal life, it is not affected by external forces. There is no strenuous exercise, so the patella can move in a normal small range in the knee area. Because the mountaineering exercise puts too much pressure on the knee, coupled with the vigorous exercise in mountaineering, it is easy to cause the patella to be pulled away from the position, thereby causing diseases of the knee joint. Wearing knee pads can fix the patella in a relatively stable position to ensure that it is not easily injured. The above mentioned is the mild braking effect of the knee pad when the knee joint is not injured. After the knee joint is injured, using the knee pad 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, thus protecting the knee joint from aggravating the condition.
