1、不同频率振动训练对膝关节位置觉影响实验探究摘要：目的：通过使用不同频率的振动训练方法，对以下肢为主的篮球专项运动员进行8周分组训练，观察比较振动训练方法对本体感觉的作用效果。方法：受试对象选取相同专项、身高体重年龄相近、训练水平及年限接近的成年男性篮球运动员共27名，分为对照组、次高频（45Hz）振动训练组、中低频（30Hz）振动训练组等三组，测定不同频率振动训练前后实际膝关节（右侧）角度位置与目标位置之间的差值，之后进行组间和组内比较。结果：训练组的本体感觉强化训练方案与正常空白对照组相比较，膝关节位置觉呈显著性差异，且8周后采用次高频振动训练组比中低频振

2、动训练组在本体感觉提髙方面呈显著性差异，尤其在45°角度差异更明显。结论：1）两组不同频率的振动训练都使受试者膝关节本体感觉（关节位置觉）出现增强的效果。2）次高频（45Hz）振动训练比中低频（30Hz）振动训练对膝关节本体感觉提高的效果更显著，尤其在45。差异更为明显。关键词：振动训练；不同频率；膝关节；本体感觉；关节位置觉；低频振动；高频振动；力量训练；运动损伤中图分类号：G804.2文献标志码：A文章编号：1007-3612(2012)11-0040-06ExperimentalResearchonImpactofKneeTopesthesiabyVi
