Many people in the climbing process because they ignore the protection of the knee, especially when descending, and eventually accumulate strain and become sick. When you are fast downhill, your knees are impacted by about 5-8 times their own weight, even a person who is not fat, from a 1,000-meter peak all the way down, the knees will suffer thousands of times about half a ton of blows, if the weight, and take a hammer to smash their knees is basically the same, the results can be good? So protect your knees from the start of climbing. 1, the most important one: downhill must not run, do not jump, slow speed, be careful. The knee is the most deadly, most of the knee problems are due to this. The correct way to descend is: the center of gravity is back and slightly lower, the front foot stand well before the center of gravity to move over (not the center of gravity on the front foot to smash down), always have a foot support on the ground. 2, as far as possible to reduce the weight. Must be measured before leaving, even to climb a small mountain, upright walking time of more than 4 hours is also normal. In general, the weight of more than 1/4 weight, down the mountain from the perspective of protecting the knee control rhythm, even in special circumstances, the weight should not try to exceed 1/3 of the weight. 3, before you start climbing, do a good job of preparing activities, including stretching, so that the joints, muscles, ligaments and so on to get a good warm-up. You can also use both fingers to rub the lower edge of the knee to promote the secretion of joint lubricating fluid. 4, use knee pads and hiking poles. Choose reliable hiking poles, preferably two, with the upper arm sharing as much of the weight of the leg as possible. I found a lot of people despise the use of protective gear, is it too “thing”? I don’t quite understand why, but it is highly recommended to use these two types of protective gear, especially trekking poles. 5, do not have a show-off mentality, or only prove that not mature enough, if you really want to climb cooler, choose to show speed on the mountain, by the way, do not forget to help everyone carrying water. 6.What kind of physical strength is the first to climb what kind of mountain, the challenge of new difficulties should be gradual, it is recommended to correctly assess their physical strength and outdoor ability before starting, think about whether they can keep up with the speed of their peers or process arrangements, it is best not to overspend their knees. 7, wear shoes suitable for climbing, and remember that generally soft land, grass, gravel slopes, snow are relatively friendly to the knee, but pay attention to non-slip, and when walking gravel road must take care of the people walking below you, otherwise it will cause a tragedy of both losses. 8, do not “lock joints”. When the thighs are overworked, walking will unconsciously lock joints, is to stretch the legs straight, which can reduce the burden on the thigh muscles, temporarily relax the muscles, but it is easy to cause knee strain, knee impact injury, ankle strain and ankle sprain. 9, strengthen the strength of the leg step muscles, developed muscles can in some cases relieve the pressure on the knee, so that the knee injury is reduced to a minimum. The quadriceps (front of the thigh) and cruciate ligament exercise, if you have the conditions to go to the gym then the best, because there are coaches to guide, can avoid the wrong posture leading to injury. 10, the last one, if the knee injury has been more serious, it is not recommended that you climb again.
