[[abstract]]The Effect of Resistance Training on Propulsive Power of Front Crawl Swimming in Children June 1999 Student：Ping-Ping Chang Advisor：Shen-Yu Hsieh ABSTRACT The purposes of this study were to examine the effect of resistance training on propulsive power of arm stroke, leg kick, propulsive power percentage of arm stroke and leg kick, stroke rate, stroke length and performance in front crawl swimming. Subjects were 43 age-group swimmers. They were 11-12 yrs. old, train 5~6 times a week, 1.5~2 hours each time in water. They were tested before and after treatment training. Subjects were rank-ordered and balance-assigned into four groups: arm stroke, leg kick, whole stroke and control groups. Treatment training consisted of 6~10 repeats of 15sec all out tethered swimming, 3 days/wk, for 6 weeks. A two-way ANOVA and Pearson's product-moment correlation were used for data analysis. The results are： 1. The experimental groups (arm, leg and whole) significantly improved (p<.05) propulsive power of arm stroke, power percentage of arm stroke, stroke rate and performance time. 2. No significant differences were observed among the experimental groups using different parts of resistance training (p>.05). 3. The propulsive power of arm stroke, leg kick were correlated with front crawl performance time (r=-.39~-.62). Conclusions： After six weeks of tethered resistance training, no significant differences were observed among the different groups. It's probably because of insufficient training intensity, volume, and duration. It also may due to children's growth and development which blur the training effect. The propulsive power of arm stroke, leg kick and whole stroke swimming were correlated with front crawl swimming time. It confirms that propulsive power is one of the most important parameters that training is trying to develop.
