Wrist movements have been identified as an important factor in producing a successful golf swing, with their complex motion influencing both club head velocity and orientation. However, a detailed analysis of wrist angles is lacking in the literature. The purpose of this study was to determine kinematics across wrists and club head characteristics during the golf swing under weak, neutral and strong grip conditions. Twelve professional male golfers executed 24 shots using a driver under three grip conditions. A six degrees of freedom analysis of the hand with respect to the distal forearm was performed using a 10-camera three-dimensional motion capture system. Differences in joint angles were explored using repeated measures ANOVAs at key swing events (onset, top of backswing and impact), in addition club head velocity and clubface angle at impact were also explored. Main findings revealed significant differences in flexion/extension and internal/external rotation for both wrists at all swing events, whereas fewer significant interactions were found in ulnar/radial deviation across grips for both wrists at all events. Clubface angle only differed significantly between the weak and the strong and neural grips, presenting a more ‘open’ clubface to the intended hitting direction. This study is the first to explore tri-planar wrist movement and the effect of different grips, such analysis has implications for coaching knowledge and practice and should inform future research into different aspects of skill, technique analysis and may inform injury mechanisms/prevention. 相似文献

摘要：在网球的基本技术中,正手被视为发球后最重要的一项技术,本研究主要运用文献资料、测量等研究方法针对国内12名男子网球选手正手击球技术的特征展开研究,重点了解与击球技术动作相关的关节角度,线速度和角速度等运动学特征,旨在揭示不同水平选手技术动作的差异,并进一步认识影响正手击球速度的核心要素。结果表明与一般水平选手相比,优秀选手在正手击球瞬间表现出更快的拍头水平速度和更快的肩部水平速度,但在躯干转动的角速度上却不存在显著性差异。在不考虑组别的情况下,击球时过程中选手的肩、髋、球拍的转动角差异很大,说明考虑标准化的技术动作并没有实际意义。 相似文献
