The aims of this study were to compare proprioception in knee rotation in Olympic-level soccer players (N=18) with non-athletes (N=18), to explore between-limb differences in soccer players, and examine correlations between proprioception and years of playing, function, physical measures and skill level. The knee rotatory kinaesthetic device was used to present stimuli of different magnitudes to determine proprioceptive acuity for internal and external active rotation, and to measure active and passive rotation range of motion (ROM). Knee rotation strength was measured using a dynamometer. Proprioceptive acuity of the athletes was significantly (P=0.004) better than that of the non-athletes. Athletes displayed significantly less passive ROM (P=0.001), higher isometric muscle strength (P=0.006) and greater hop for distance (P=0.001) than non-athletes. No significant between-limb differences were found in the athletes in any objective outcome measure. Internal rotation proprioceptive acuity was negatively correlated with coach-rated ball skill (r=-0.52) and positively correlated with internal rotation ROM (r=0.59). Our findings suggest that highly trained athletes possess enhanced proprioceptive acuity and muscle strength that may be inherent, or may develop as a result of long-term athletic training.
本研究的目的是比较奥运水平足球运动员（N = 18）与非运动员（N = 18）在膝关节旋转方面的本体感觉，探讨足球运动员两下肢之间的差异，并检验本体感觉与比赛年限、功能、身体测量指标和技能水平之间的相关性。使用膝关节旋转动觉装置呈现不同强度的刺激，以确定内旋和外旋主动旋转的本体感觉敏锐度，并测量主动和被动旋转活动范围（ROM）。使用测力计测量膝关节旋转力量。运动员的本体感觉敏锐度显著优于非运动员（P = 0.004）。与非运动员相比，运动员的被动活动范围显著更小（P = 0.001），等长肌力更高（P = 0.006），跳远成绩更好（P = 0.001）。在任何客观结果测量中，均未发现运动员两下肢之间存在显著差异。内旋本体感觉敏锐度与教练评定的控球技术呈负相关（r = -0.52），与内旋活动范围呈正相关（r = 0.59）。我们的数据表明，训练有素的运动员具有更高的本体感觉敏锐度和肌肉力量，这可能是天生的，也可能是长期运动训练的结果。
