查询词典 jump joint

The experimental conclusion determined that if the knee joint angle can be kept at 140-150 in the buffer jump at various liftoff heights, and the coax joint as well as the knee joint can be larger than 170 at the instant liftoff, an optimal jump can then be achieved.

以上实验结果予以讨论后获得以下结论：苏翊伦选手在不同跳跃高度之起跳动作，若缓冲期间起跳脚膝关节角度能维持在140度？

Taking the moments of hip and knee joint as its controlled variables, the simulation of the motion equation shows that: After increasing the joint moment at the cushioning phase, the vertical velocity of the body center of mass distinctively speedup while horizontal velocity fall to some degree. Thus, the resultant velocity remains basically constant, but the result distance of long jump can be increased due to the enlargement of the angle of take-off.

以髋、膝关节肌力矩作为运动方程的控制变量，对其修改后的模拟结果表明：增大缓冲阶段的关节肌力矩后，人体重心的垂直速度得到明显提高，而水平速度则有所下降，在腾起合速度变化不大的情况下，由于腾起角的增大提高了跳远成绩。

After comparing with previously report, conclusion was as follow: when players use take-off spike movement by single-foot, the strides should increase progressively after observing the ball's direction, and raise the height of jump by getting faster horizontal and vertical velocity of body gravity. In order to avoid increasing the time of take-off, the body gravity is inadvisable to drop so much. In air motion period, player's movement of arm swing will influences the time of spike, if we emphasize the quick offensive, it should reduce the movement of arm swing to decrease the time of spike. When spiking, the joint of elbow should flex by a little range to make forearm powerful.

经由本实验结果与过去研究比较后得到以下结论：选手在执行单脚起跳扣球动作时，助跑的步幅宜在观察球的动向后，采取递增的方式助跑，并加快身体重心水平速度及垂直速度，以提高起跳高度；起跳期起跳脚踏入瞬间身体重心不宜大幅度的下降，以避免增加起跳所花费的时间，影响扣球的节奏及战术的执行；空中动作期时，选手的挥臂动作会影响击球时间，若要强调快速的进攻节奏，宜减少扣球的挥臂动作，以降低完成扣球所需的时间；而击球瞬间肘关节宜保持小幅度的弯曲，以发挥前臂的力量和速度。
