健康剑道运动员剑道挥击动作中矢状面踝关节和膝关节的协调

BackgroundJointcoordinationpatternsduringsportsmovementsarebelievedtoberelatedtosportsperformanceandinjury�风险。本研究的目的是通过使用改进的矢量编码分析来量化关节协调，并确定健康经验丰富的kendo运动员在kendostrike- thrustemotion中左膝和膝关节的个体协调模式。方法:15名有经验的大学田径运动员(年龄20.4±1.2岁，身高171.5±4.0厘米，体重73.9±9.1公斤，运动经验11.1±3.1岁)自愿参加本研究。�Three-dimensionalkinematicdatawascol——lectedwhileparticipantswereperformingthreesetsofkendomotionsatdistancesof�2�mfromthetarget。对关节纠缠数据进行平均处理，并使用改进的矢量编码分析，以确定在kendox -走向-推力运动的单个支持阶段的段间协调模式。结果:我们在7名参与者中观察到一个“n形”的协作模式，而在其他7名参与者中，我们观察到一个“顶部”的协作模式，在kendostriker -thrustmotion的单一支持阶段。一个��participantpresentedauniqueco-ordinationpatternwhichcouldnotbedefined。�另外,�theratioofeach�jointco-ordinationpatternvariedamongthekendoathletes。结论:我们确定了左膝和踝关节在单支撑阶段的两种不同的关节协调模式，即“n形”和“顶型”模式。�Thestressappliedtothelower�extremitymightbedifferentbetweenthetwojointco-ordinationpatterns。
