项目摘要
This study was aimed at elucidating the biomechanics of the Super-Skating (SS) technique in a cross-country skiing. The experiments were carried out on a treadmill to prescribe a degree of the slope, which was changed a degree from 3% to 11% for every 2% (5 conditions). The subject performed SS technique with roller skis at the speed of 5.5 km/h. The pole-pushing and ski-kicking movements during roller-skiing ware analyzed biomechanically. The poling angle and ski-opening angles were measured by three-dimensional motion capture, and the pole-pushing force and ski-kicking force were acquired from strain gauges and foot sensors, respectively. As a result, the ski-opening angle and the pole-pushing force were significantly (P<0.05) increased at the slope condition of 11% compared with those of 3% and 5%. Neither the poling angle nor ski-kicking force changed on any condition. Collectively these data indicate that dynamic corresponding in the poling was different from that in the skiing. For the increase of a degree of the slope, the skier increases the polling force itself in the polling movement and changes the direction of the ski-kicking force in the skiing.
本研究旨在阐明越野滑雪中超级滑冰(SS)技术的生物力学。实验是在跑步机上进行的,规定了坡度,每2%坡度从3%变化到11%(5种条件)。受试者以 5.5 公里/小时的速度使用滚轴滑雪板进行 SS 技术。对轮滑运动中的推杆和踢滑雪动作进行了生物力学分析。通过三维运动捕捉测量撑杆角度和滑雪板张开角度,并分别从应变计和脚传感器获取撑杆推力和滑雪板踢力。结果表明,与3%和5%坡度条件相比,11%坡度条件下滑雪板张开角度和推杆力显着增加(P<0.05)。在任何条件下,极化角度和滑雪踢力都没有改变。总的来说,这些数据表明撑杆中的动态对应与滑雪中的动态对应不同。对于坡度的增加,滑雪者在轮询运动中增加轮询力本身并改变滑雪时的滑雪踢力的方向。
