Brief Summary

This study was conducted to investigate the effectiveness of ankle muscle strengthening program of 8 weeks on the underwater dolphin kick performance in young swimmers. This study was a randomized controlled trial. Swimmers was divided in two groups; eccentric ankle muscle-strengthening exercises and control group. The outcome measures were strength of plantar flexors, dorsal flexors, internal rotators, external rotators and 5-meter underwater dolphin kick time.

Model Details: In order to examine the effect of strengthening exercises on performance amongst competitive young swimmers, a randomized controlled trial was undertaken. Swimmers were divided into two groups: Exercise (n=13) and the control groups (n=13). Both groups were assessed for 5-metre underwater swim time and ankle muscle strength before and after 8 weeks of normal swimming training. The exercise group received eccentric ankle strengthening exercises with an elastic band, in addition to their regular swimming training. Participants completed 24 exercises over 8 weeks, with 3 non-consecutive training sessions per week. Dynamic (2 minutes) and static stretching (2 minutes) exercises were performed as before the training session.
