The Effect of core stability exercises with Swiss ball on the performance of sub-elite adolescent swimmers

Researches has identified the importance of core training in injury prevention. However, there are limited information about relationship between core stability and swimmer performance. Therefor the purpose of this study was to determine the effect of core stability training on performance of sub elite adolescent swimmers. Thirty male swimmers were randomly allocated in the control (n=15) and intervention (n=15) groups. The intervention group completed the core stability training, three times per week for 8 weeks. Analysis covariance were used for determine the effect of core stability exercise on 50-m front and back crawl, butterfly, and breast- stroke race. The results showed that there was significant difference in time of 50-m front crawl and breast- stroke race, back crawl and butterfly race. According to the results, core muscle strengthening enhanced the performance in young swimmers projected as significant improvements in 50-m front crawl and breast- stroke sprint time.
