The purpose of this study was to investigate the effect of 12 weeks water training in shallow and deep part of pool on balance and lower limb muscles strength in elderly. Thirty-six healthy male elder selected as statically sample in three groups. Two experimental groups performed 12 weeks water training in shallow and deep part of pool for three sessions in per week. Balance and lower limb muscles strength tests performed before and after the training protocol. Single leg stance time and Y test were used for measuring static and dynamic balance respectively. MMT system was used for measuring lower limb muscles strength. Findings of this study indicated there is significant improvement on static balance after performing training protocol in shallow and deep part of the pool (p=0.03) .in contrast, dynamic balance of dominance leg has significant improvement in 3 directions of Y test while dynamic balance of non-dominance leg has significant improvement in anterior direction only (p=0.01). On the other hand, there is only significant improvement in hamstring muscles strength after training protocol in shallow part of the pool while all muscles strength except internal and external rotators have significant improvement after training protocol in deep part of the pool (p<0.05). It seems 12 weeks water training in shallow and deep part of pool has significant improvement on balance but performing training in deep part of pool has more significant improvement on lower limb muscles strength in elderly.
