中文摘要:
      利用三维红外运动捕捉系统对运动员王丽的跨栏动作进行影像捕捉、分析,揭示其现有技术动作的特点。研究发现王丽跨栏技术的特点:(1)跨栏步幅大,主要体现在起跨步步幅大,这可能对其腾空时间有影响;着地距离较短,比较合理。(2)起跨腿支撑时间和摆动腿支撑时间较短,说明其下肢肌肉较为有力,能够快速支撑其身体质量。(3)腾空时间较长。
英文摘要:
      3D infrared motion capture system was used to capture and analyze the image of Wang Li’s hurdling action so as to reveal the characteristics of her technical movements. The study has discovered her technical characteristics as follows,(1)Her hurdling start stride is big. This may affect her air time. Her short landing distance is reasonable. (2)Both the supporting time of her hurdling start leg and swinging leg is short. This means she has strong lower limb muscles which is able to support her weight quickly.(3)The time in the air is relatively long.
