目的:研究踺子转体180°前手翻接直体前空翻类跳马动作,揭示这类跳马的运动学规律和技术特点.方法:对程菲和洪淑贞完成的"踺子转体180°前手翻接直体前空翻转体180"(简称"R180"),以及程菲完成的"踺子转体180°前手翻接直体前空翻转体540°"("程菲跳")进行三维运动学分析,对三组跳马动作身体重心的水平速度和垂直速度、主要关节的位移、关节角度、身体翻转角速度等运动学参数进行对比分析.结果:三组动作踏板时重心水平速度基本相同,踏板及推手阶段关键位置的关节角度相近,但"程菲跳"推离马重心垂直速度和第二腾空时间明显高于"R180",第二腾空转体角速度略大于"R180"的3倍,而翻腾角速度略小.结论:踺子转体180°前手翻接直体前空翻类跳马动作触马前的技术动作基本相同,难度较高的技术动作需要更高的推离马垂直速度和更快的第二腾空转体角速度. 相似文献

采用三维高速摄影和影片解析的方法,对我国优秀男子体操运动员黄力平、黄华东等人完成跳马“踺子转体180°前手翻”类动作纵转180°技术时的空间及时空特征等,进行比较分析。结果显示,完成纵转180°技术时,应避免在踏板阶段过早转体;应充分利用手臂的非对称性运动,做到“快转体,早摆腿”;推手阶段要尽可能利用腕、肘、肩的弯屈度,充分推伸、拉展等。 相似文献

This study aimed to investigate the effects of forward trunk lean on hamstring muscle kinematics during sprinting. Eight male sprinters performed maximal-effort sprints in two trunk positions: forward lean and upright. A three-dimensional musculoskeletal model was used to compute the musculotendon lengths and velocity of the biceps femoris long head, semitendinosus, and semimembranosus muscles during the sprinting gait cycle. The musculotendon lengths of all the three hamstring muscles at foot strike and toe-off were significantly greater during the forward trunk lean sprint than during the upright trunk sprint. In addition, a positive peak musculotendon lengthening velocity was observed in the biceps femoris long head and semimembranosus muscles during the late stance phase, and musculotendon lengths at that instant were significantly greater during the forward trunk lean sprint than during the upright trunk sprint. The present study provides significant evidence that a potential for hamstring muscle strain injury involving forward trunk lean sprinting would exist during the stance phase. The results also indicate that the biceps femoris long head and semimembranosus muscles are stretched during forward trunk lean sprinting while contracting eccentrically in the late stance phase; thus, the elongation load on these muscles could be increased. 相似文献

Scapulohumeral kinematic assessment of the forward kayak stroke in experienced whitewater kayakers 总被引：1，自引：0，他引：1

By understanding the normal humeral and scapular kinematics during the kayak stroke, inferences about the relationship of kayaking technique and shoulder injury may be established. The purpose of this study was to describe scapular and humeral kinematics and to compare dominant versus nondominant symmetry in healthy whitewater kayakers performing the forward stroke. Twenty-five competent whitewater kayakers (mean age: 34.1 +/- 9.4 years, mean height: 1.768 +/- 0.093m, mean mass: 78.2 +/- 13.0 kg) underwent humeral and scapular kinematic assessment, using an electromagnetic tracking device, while kayaking on a kayak ergometer. Paired t-tests were used to determine symmetry. Scapular and humeral kinematic means and standard deviations at six time points during the kayak stroke were described. Scapular and humeral kinematics were shown to be similar upon bilateral comparison. The greatest potential for injury during the forward stroke may be at thrust paddle shaft vertical when the humerus is maximally elevated in internal rotation and adduction as subacromial structures may be mechanically impinged. The relationship between scapulohumeral kinematics related to injury at other time points are also described. 相似文献
