The effect of 8 weeks of core stability training with Swiss ball on the balance in 12 -15 year old soccer players

The purpose of this study was to evaluate the effect of 8 weeks of core stability training with Swiss ball on the balance of teenager soccer players. 30 teenager soccer players were selected and divided randomly into two control and experimental groups. The training program of experimental group was included core stability exercises for 8 weeks، 3 times per week. In first four weeks experimental group performed exercises in two sets with 5 repeats and second four weeks of 2 sets with 10 repeats. In this period، the control group only participated in the practice of soccer. The evaluation of the static balance was done by Stork test and the dynamic balance was done by Y test. After normality test of data mean distribution by Kolmogorov-Smirnov test، paired- samples t-test was used for extraction of results and significance level considered if p≤0. 05. Results showed significant differences in poster medial (p=0. 002) and poster lateral (p=0. 04) direction in the experimental group in post-test. There were no significant differences in static balance (p=0. 91) and anterior direction between pre-test and post-test (p=0. 33). According to the results of this research، the core stability exercises can be performed on teenager soccer players and children by coaches and teachers to improve balance and prevent sport injuries.
