Abstract
This study aimed to study the effects of a dry-land training program on muscle strength, freestyle 100m, and IGF-I concentration in young swimmers. The participants consisted of 11 male students of the Assumption College Sriracha swimming club, aged 9-15 years old, with 1-5 year swimming experience, divided into a control group and an experimental group with Match Pair and random assignment. The experimental group conducted with a dry-land training program for 12 weeks, 2 days a week (Tuesday and Thursday) while participants in the control group practiced with the regular training of Assumption College Sriracha swimming club. Muscle strength and freestyle 100 m were measured after dry-land training weeks 4, 8 and 12 and IGF-I concentration was tested after dry-land training week 12. The data were analyzed using the Mann-Whitney U test, Friedman test and Wilcoxon Signed Ranks Test.
The results were found that muscle strength and freestyle 100m of the experimental group after training week 12 were statistically increased at the significance level of .05 while no significance difference was found in IGF-I concentration after training week 12 and before training. No significant differences of muscle strength, freestyle 100m, and IGF-I concentration were found between the control group and the experimental group after training week 4, 8 and 12 at the level of .05. However, the change of muscle strength, freestyle 100 m, and IGF-I concentration in young swimmers were not clear. Thus, future study is needed.
