Research examining the proximal-to-distal sequencing of segments of the body involved in overarm throwing has been equivocal: some studies have found support for the concept while others have not. The aim of the present study, therefore, was to determine if there is a proximal-to-distal sequence in the timing of the movements of joints and the distal endpoints of segments in overarm throwing. The three-dimensional kinematics of a penalty throw in experienced team handball players (n = 11) were recorded and analysed with regard to the timing of events. We analysed the timing of the maximal velocity of the distal endpoints of six segments and the maximal angular velocity in 11 joints, as well as the initiation of these joint movements. A temporal proximal-to-distal sequence was observed only for the initiation of the joint movements. No such sequence was found for maximal velocity of the joints and distal endpoints of segments.
一些研究支持这一概念,而另一些则不然。因此,本研究的目的是确定在过肩投掷中关节运动和节段远端端点运动的时间上是否存在从近端到远端的顺序。记录并分析了经验丰富的团队手球运动员(n = 11)罚球时的三维运动学,以研究事件发生的时间。我们分析了六个节段远端端点的最大速度、11个关节的最大角速度以及这些关节运动的起始时间。仅在关节运动的起始阶段观察到了从近端到远端的时间顺序。在关节和节段远端端点的最大速度方面未发现此类顺序。
