Although to improve balance and grasp the proprioception, recommended balance exercises, but there is not clear mechanism for the effectiveness of equilibrium training on healthy subjects. Suitable interaction of varios system of body and environment are necessary to maintain of the balance. Balance exercise is prescribed to improve balance and proprioception. There is not clear mechanism about the effectiveness of these exercise on healthy subjects. So The purpose of this study was to the Effect of 8 weeks of ankle-specific balance training on the balance and knee and ankle proprioception of adolescent volleyball players. the statistical sample of this study was 30 adolescent volleyball players in the league Golestan Which were selected as accessible and were randomly assigned into experimental and control groups. The experimental group performed 8 weeks and 3 sessions per week of ankle-specific balance. The results showed that there was a significant difference in the mean of balance and errors in reconstructing the angles of knee and ankle after exercise in the experimental group, while in the control group it was not significant. Results of this study showed that Balance Training can improve balance and proprioception in the knee and the ankle.

Proprioception is essential for joint function and through which individual can detect body parts movement in space. Aim of present study is to investigate effect of balance training on unstable platform with tilting, translation and combined motion on knee joint position sense in active young males. 39 healthy active male divided in to three training and control (n=9) groups. Training on unstable platform with tilting motion group (n=10), Training on unstable platform with translating motion group (n=10) and combined training group (n=10) performed exercises program for 8 weeks, three times a week. Errors in repositioning of knee joint in 30, 45 and 60⁰ angles (active and passive) was measured by Biodex system 3, before and after training period. Data was analysed by using one-way ANOVA test (P≤0/05). Although after 8 weeks, active and passive errors in repositioning of knee joint in mentioned angles decreased in training groups but this difference was not significant (P≤0/05). Balance training on unstable platform alone cannot have a big effect on knee joint position sense in active young male.
