摘要
研究目的:实验着重从运动学角度出发对裸足与穿鞋两种状态下,以不同速度在跑台上跑步时支撑时相肢膝关节角度和踝关节角度变化进行分析。研究方法:6名普通男性大学生在跑台上,分别以7.5km/h、10km/h、12.5km/h3个速度在裸足与穿鞋两种情况下进行实验。使用高速摄像机拍摄其跑步过程,得到下肢环节运动学参数计算关节角度,并探究其变化规律。研究结果和结论:穿鞋时支撑时相时间大于裸足时;不论裸足还是穿鞋,着地角度、膝关节角度和踝关节角度等指标上存在明显变化。
Research objectives： this study analyzes the knee and ankle joint angle on treadmill under the different riding speeds in standing phase emphatically from the kinematics of two kinds of bare feet and running shoes.Research methods： six ordinary male college students running on treadmill, with 7.5 km/h, 10 km/h, 12.5 km/h speed in bare feet and running shoes. In running process using high-speed cameras, receiving the lower limb kinematics parameter and calculation joint angles and their changing regularity. Research conclusion： the standing phase time is running shoes longer than the bare feet; the touchdown, knee and ankle joint angle and so on on are obvious changes on running shoes or not.
