There are three functions of knee pads: one is braking, the other is heat preservation, and the third is health care.

1. Insulation function:
The knee part is very easy to catch cold without knee pads. Many knee joint diseases are related to the cold knee, especially in the mountains, where the mountain wind is very cold and hard. There is no muscle movement, so it is not hot. When people feel that the legs are very comfortable to dissipate heat, the knees are actually getting cold. At this time, if you wear knee pads, the thermal insulation effect of the knee pads can be reflected.
2. Braking action:
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 is 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 mountaineering exerts 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 original 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.
3. Health care function:
This is relatively easy to understand. Under the premise of having the heat preservation and braking effect of traditional knee pads, the far-infrared negative ion energy layer is added to the production material of the new far-infrared negative ion knee pad, which can cause the subcutaneous biomolecules of the knee to resonate, thereby making Deep tissue fever can promote blood circulation, improve microcirculation, relax meridians and activate collaterals. Long-term wearing can effectively prevent arthritis, rheumatism and other knee diseases.

Since knee pads are so important, we must choose a knee pad product that suits us. Here are some ways to choose sports knee pads.

1. Materials
When we choose knee pads, we must first look at what material it uses. Generally, high-quality ones are softer and not stiff when you touch them with your hands, so that you will be more comfortable when wearing them, and your knees will not feel uncomfortable. Moreover, its thermal insulation effect is also good, especially after a lot of exercise, sweating is more, if the wind will induce joint pain, it can protect the knee.
2. Perforated breathable perspiration
Tied to the leg, not only requires warmth, if you sweat a lot, you will feel wet and not too comfortable. Therefore, you can choose a perforated one, because its breathability is better, it can discharge the sweat inside, and give the knee a comfortable environment.
3. Paste
Furthermore, it is the sticking part of it. When the amount of exercise outdoors is relatively large, it is easy to cause the knee pad to not be in the same position as the joint, and it will fall off, which not only affects the activity, but also needs to stop and re-stick, which is more troublesome. Therefore, its slip resistance should be good, but also soft. This also protects your knees, so you don’t have to worry about sweating it out.
4. Design
Choosing a knee pad not only depends on the appearance, but also whether its design is reasonable. The rationality means that it does not have to be regular, but has a certain curvature. It is based on the curvature of our knees to make a corresponding arc. During exercise It can also provide appropriate strength to protect the knees and allow the body to move freely. If it is allowed, you can wear it when choosing, feel whether it is convenient and comfortable, and have a tactile experience in advance, so as not to hinder the movement in future use.
