研究设计：对照实验室研究：cross-sectional.OBJECTIVE:确定通过被动运动检测阈值（Tensor）测量的本体感受是否在定期参加中等强度健身运动的个体与参加高强度熟练运动的个体之间存在差异。背景：以前的研究一直模棱两可，运动训练是否与上级本体感受敏锐度，特别是，包括动态姿势挑战的运动，如切割和旋转。方法：招募了两组25名健康个体（18-32岁）。一组是每周进行5到10小时中等活动水平锻炼的人。另一组的参与者进行高活动水平的锻炼，包括高速切割和旋转活动，每周至少10小时。本体感觉的测定使用Tendon，其中膝关节以0.5度/s或更小的角速度从40度的膝关节屈曲的起始位置缓慢地伸展或屈曲。结果：参与竞争性的、高强度的熟练运动的个体表现出更好的Tendon敏锐度（平均值+/- SD，0.81度+/- 0.38度; P
STUDY DESIGN: Controlled laboratory study: cross-sectional.OBJECTIVE: To determine if proprioception, measured by the threshold to detection of passive motion (TDPM), differed in individuals who regularly participate in moderate-intensity exercise for fitness as compared to individuals involved in high-intensity skilled exercise.BACKGROUND: Previous research has been equivocal as to whether exercise training is associated with superior proprioceptive acuity, in particular, exercise that includes dynamic postural challenges such as cutting and pivoting.METHODS: Two groups of 25 healthy individuals (18-32 years old) were recruited. One group consisted of individuals who performed moderate-activity level exercises for 5 to 10 hours per week. Participants in the other group performed high-activity level exercises, including high-speed cutting and pivoting activities, at least 10 hours per week. Proprioception was determined using TDPM, in which the knee was slowly extended or flexed at an angular velocity of 0.5 degrees/s or less from a starting position of 40 degrees of knee flexion.RESULTS: Individuals participating in competitive, high-intensity skilled exercise demonstrated better acuity (average of both limbs) of TDPM (mean +/- SD, 0.81 degrees +/- 0.38 degrees; P
