What are the advantages and disadvantages of knee pads?

1 insulation

The local part of the knee is very easy to catch cold, and many knee diseases are related to the cold of the knee, especially in mountainous areas, where the mountain wind is very cold and hard. Often the leg muscles feel very hot because of constant exercise, while the knees are not hot because there is no muscle activity. When we feel comfortable cooling our legs, our knees really catch cold. At this time, if we wear knee pads, the warm effect of knee pads can be reflected.

2 Braking

The knee joint is the center of the intersection of the upper and lower bones of the calf, with meniscus at both ends and patella at the back. The patella is stretched by two muscles, suspended in front of the intersection of leg bones, and slides at will. In normal life, because it is not affected by external forces and there is no strenuous activity, the patella can move in an ordinary small range at the knee. Due to the excessive pressure on the knee caused by mountaineering activities and the intense activities in mountaineering, the patella is easily pulled away from its original position, leading to knee joint diseases. Wearing knee pads can make the patella flow in an absolutely fluctuating position, ensuring that it will not be injured casually. It says above that a gentle kneepad should be used when the knee joint is not injured. After the knee joint is injured, the knee pads with heavy brakes can reduce the bending of the knee joint, keeping it in a straight line from thigh to calf, reducing the bending of the knee joint, so that the knee joint will not aggravate the condition.

Disadvantages: affecting skin ventilation, reducing the exercise of knee joint muscles and increasing the burden on the knee.

What is the main function of 1?

Knee pads have three functions, one is braking, the other is heat preservation, and the third is health care. Not much to say about keeping warm, the knee is very easy to catch cold, and many knee diseases are related to the cold of the knee, especially in mountainous areas, where the mountain wind is very cold and hard, and the leg muscles often feel very hot because they have been exercising, while the knee is not hot because there is no muscle movement. When people feel comfortable cooling their legs, their knees actually catch cold. At this time, if they wear knee pads, the thermal insulation function of the knee pads can be reflected.

Mainly talk about the braking function of knee pads. Knee joint is the intersection of thigh bone and calf bone, with meniscus in the middle and patella in front. The patella is stretched by two muscles and suspended in front of the intersection of leg bones, so it is very easy to slide. In normal life, the patella can move normally in a small range because it is not affected by external forces and does not exercise vigorously. Due to the excessive pressure on the knee in mountaineering and the strenuous exercise in mountaineering, it is easy to pull the patella away from its original position, thus causing knee joint diseases. Wearing knee pads can fix the patella in a relatively stable position and ensure that it is not easy to be injured. What is mentioned above is the gentle braking effect of the knee pad without injury to the knee joint. After the knee joint is injured, the knee pad with heavy braking can reduce the knee bending, keep it in a straight line from thigh to calf, and reduce the knee bending, thus protecting the knee joint from aggravating the disease.

Let's talk about the health care function of knee pads first, which is easier to understand. On the premise of having the thermal insulation and braking effect of traditional knee pads, because the far-infrared negative ion energy layer is added to the new far-infrared negative ion health knee pads, it can cause the vibration of biomolecules under the knee skin, and then heat the deep tissues, thus playing the roles of promoting blood circulation, improving microcirculation, relaxing meridians and activating collaterals. Wearing knee pads for a long time can effectively prevent and treat knee joint diseases such as arthritis and rheumatism.

2 Selection method?

According to different functions, two kinds of knee pads for mountaineering are recommended. One is the thick kneepad that is common in outdoor shops. There is a big hole in the front to expose the knee, and it is usually tied and fixed with adhesive buttons. This kind of kneepad is not easy to bend the knee after binding, and the thigh and calf are always in a straight line with the knee, which is very suitable for serious "braking" after knee injury, and it is not easy to be used as daily protection of the knee because of the impermeability of its material. The other is a thin kneepad covering the knee, which has certain elasticity. After wearing it, the knee can still move freely, but you can obviously feel the patella tightening slightly. This kind of knee pad with light braking can be used to protect the knee in normal exercise, and it is very breathable, so you will hardly feel any inconvenience when wearing it. Therefore, this light brake kneepad is recommended for every mountaineering activity.

3 how to wear it?

Donkey friends all know the function of knee pads, but few people know how to use them correctly and what will happen if they use them improperly. Knee pads on the market are roughly divided into professional kneepads and non-professional kneepads, which only refer to non-professional kneepads here.

There are two kinds of non-professional kneepads, which are divided into summer and autumn kneepads (short kneepads) and winter and spring kneepads (generally long kneepads with fur inside the skin). The quality and price of various knee pads vary greatly, so motorcycle riders can choose according to their own needs and economic conditions.

Some hikers wear knee pads on long trips, but they often don't wear them on short trips. I don't know "Rome wasn't built in a day". After riding for a long time and a short distance, the knee joint will still get sick, so remind motorcyclists to protect their knee joint from 0 km, and it is too late to wear knee pads if the knee joint is sick.

Some donkey friends think that knee pads should be worn in winter and not in summer. This view is wrong. Because of the high temperature in summer, the pores of the skin expand much more than in winter. If riding without knee pads, the knee joint is more vulnerable to the impact of high-speed wind, and the chance of getting sick is greater.
