The comparison of knee joint position sense in soccer player, volleyball player and non-athlete men

proprioception and balance are two effective factors on improving performance and sport injury prevention, but the effect of participate in different sport activates on this sense has been studied less. So, the aim of this study was to compare the knee joint sense position in soccer player, volleyball player and non-athlete men. 45 subjects including 15 soccer players, 15 volleyball players, 15 non Participated in this study. The Knee joint position sense of the dominant leg of these subjects was assessed through 15, 30, 60 degrees flexion reconstruction with closed eyes and in closed movement chain using electrogoniameter. Data were analyzed using one way ANOVA test and TUKEY POST HOC test. The results showed that the mean of absolute error in 60 degree reconstruction in volleyball players is significantly less than absolute error in soccer players and non-athletes (P<0.05). There was not significant differences between mean absolute error in 15, 30 degrees in the three groups of subjects (P>0.05). Volleyball players have better knee joint position sense in 60 degree reconstruction. Maybe plyometric training specially jump- descend with body weight can help to improving knee joint position sense.
