内容記述
内容記述 The range of posture and body movement in which balance could be maintained while skiing over a bump on a straight downhill run was investigated. A bump was constructed on a slope with 13.5 - degree inclination. The bump was 0.5m high and 2m long. One highly skilled, two intermediate skiers and two beginners were employed as subjects. Each skier was asked to run straight down over the bump using a different kind of posture each time in the course of three runs: 1) normal, 2) maximum forward and 3) maximum backward leaning. Body movement in each trial was filmed from the side using a 16mm high speed instrumentation camera (100 f.p.s.). By analyzing the film, the angle of hip, knee and ankle joints as well as the body inclination and the location of center of gravity (C.G.) were obtained. The stable range of balance from maximum forward to maximum backward leaning posture was greater and the locus of C.G. was more parallel to the slope in the highly skilled skier. More detailed analysis of body movements showed that the flection and extension of hip and knee joints when passing over the bump were important to absorb the shock or the bump. Comparison of these movements of the highly skilled skier with those of others revealed the most significant difference to be the range of the knee joint angular change. Results of this investigation showed that the highly skilled skier is able to traverse the next bump successively even though he or she temporarily assumes a forward or backward leaning posture after skiing over the preceding bump. Moreover, his or her outstanding shock absorbing movement also serves to avoid falling into any of these postures.
