膝蓋對於運動員而言是非常重要的身體關節。膝蓋是人體最大的承重關節，一般人平均可承重35公斤。但是，承重越多，關節軟骨越容易磨損，膝蓋也退化較快。平時站立走路對於膝蓋的負重大約為體重一倍，跑步為四倍，打球更是高達六倍。想到我每星期膝蓋承受300公斤以上的刺激不下100次，我就相當替我的膝蓋感到擔憂。我是一個排球選手，排球是一個對於膝蓋磨損相當劇烈的運動。不僅需要反覆的跳躍，防守接球也需要維持半蹲的姿勢，更有不少撲在地板上的接球動作。跳躍落地的瞬間對於膝蓋的衝擊為身體五倍的重量，半蹲的姿勢則是上半身的六倍重量以上。排球中的高級動作魚躍可避免膝蓋直接觸地。但是跟我一樣技術不純熟的選手，多次在撲接快落地的球，不僅會造成瘀青，更是直接造成膝蓋的撞擊傷害。我和許多隊友已感受到膝蓋過度磨損的不適，更有人因膝蓋修復狀況不佳而膝蓋積水。更嚴重者，許多運動員在激烈的傷到膝蓋的十字韌帶，只能結束運動生涯。

Knee is very important for the athlete's body joints. The knee is the body's largest weight-bearing joints, usually the average person can load 35 kg. However, the more load, the more likely articular cartilage wear and tear, the knee is also degraded faster. Usually stand to walk for weight-bearing knee is about twice the weight, running four times, play is as high as six times. I think every week knee withstand more than 300 kg of stimulus less than 100 times, I quite worried for my knees.
I am a volleyball player, volleyball knee is worn for a very strenuous exercise. Not only repeated the jump, squat defensive catcher who also need to maintain the posture, many of bashing the ball on the floor action. Jump in the moment of impact to the knees is five times the body weight, squat posture is more than six times the weight of the upper body. Advanced volleyball diving operation can avoid direct contact with the knees. But like me, technology is not skilled players, several times in quick flutter then landing the ball will not only cause bruising, it is a direct result of the impact of a knee injury. I and many of his teammates have felt excessive wear knee discomfort, but it was due to poor state of repair knee and knee hydrocephalus. More severe cases, many athletes in the fierce cruciate ligament injury to the knee, can only end their careers.

However, the more load, the more likely the joint cartilage is to wear and the knees degrade faster. Standing walking is about twice as heavy a weight for the knee, four times as much for running and up to six times as much as playing. The thought of me suffering no more than 300 kilos of stimulation a week makes me quite worried about my knees.
I am a volleyball player, volleyball is a very intense knee wear of the sport. Not only need to repeated lying, the defensive catch also need to maintain a semi-crouch posture, but also a lot of jumping on the floor of the catch action. The moment the jump falls to the ground is five times the weight of the body, and the half-crouch position is more than six times the weight of the upper body. The high-level action fish in volleyball avoids direct knee contact to the ground. But like me, the technical lying players, many times in the fast landing ball, not only will cause bruising, but also directly cause knee impact injury. I and many of my teammates have felt the discomfort of excessive knee wear and knee accumulation due to poor knee repair. More seriously, many athletes have suffered a severe knee cruciate ligament injury that will only end their athletic careers.

However, the more load-bearing, the easier the articular cartilage is to wear, and the faster the knee degeneration. Usually, the weight of standing and walking to the knee is about twice of the weight, running is four times, playing is as high as six times.

I'm a volleyball player. Volleyball is a sport with severe knee wear. Not only need to repeatedly jump, defensive catch also need to maintain a squat position, there are a lot of catch on the floor. The impact of jumping and landing on the knee is five times the weight of the body, and the squat position is six times the weight of the upper body.

More serious, many athletes in the intense injury to the knee cruciate ligament, can only end their sports career.
