本研究的目的是决定高山滑雪运动员在进行一个规定动作时合成的膝关节力与矩。动作的分析由从一个地面突起物着地及回复的起始(如果需要的话)所组成.合成的负荷是利用一种近似的反动力学而获得的。对两个特定的滑雪者的结果进行对比,一个滑雪者以良好的方式着地,另一个则着地方式不佳。着地方式不佳的滑雪者其膝曲屈及膝关节的合成力与矩均大于着地方式良好的滑雪者.着地方式不佳的滑雪者的动作曾有结合外交叉韧带损伤现象.然而本研究中所获得的资料并不表明上述两种滑雪者具有韧带损伤的(现象)危险性。膝韧带損伤是与滑雪有关的最流行的損伤。并在所有的滑雪損伤报告中曾占20～25％的比例(例如:Benchtel Ellman与Jordon 1984;Howe及Johnson 1982;Johnson,
The purpose of this study is to determine the knee joint forces and moments that mountain skiers use when performing a prescribed maneuver. The analysis of the motion is made up of the ground from a ground protrusion and the beginning, if necessary, of the reply.The resultant load is obtained using an approximate reactionary kinetics. A comparison of the results of two specific skiers shows that one skier landed in a good way and the other did not. The less-skilful skiers had more knee flexion and knee joint strength and a greater torque than the skier who had been on the ground, and skier-impaired skiers combined with ACL injuries. The information obtained does not indicate that the above two skiers are at risk of ligament damage. Knee ligament injury is the most prevalent injury associated with skiing. And has accounted for 20-25% of all ski damage reports (eg Benchtel Ellman and Jordon 1984; Howe and Johnson 1982; Johnson,
