방과 후 수영운동이 초등학생들의 건강관련체력 및 성장관련인자에 미치는 영향

Abstract

The purpose of this study was to examine the effects of a swimming program for 12 weeks on health-related physical fitness and growth hormone in elementary students with age of 11-13. The subjects were elementary students with age of 11-13 who resided in the J area. An exercise program was conducted 60 minutes per day, 3 times per week for 12 weeks. Comparison and analysis were made in RPE(Ratings of Perceived Exertion) 10~14. The following conclusions were drawn.

First, the change of health-related physical fitness was compared and analyzed before and after the swimming program. The exercise group showed a significant difference in muscle strength(p<.001), muscle endurance(p<.001), flexibility(p<.01), and cardiovascular endurance(p<.001). Second, the change of growth hormone was compared and analyzed before and after the swimming program. The exercise group showed a significant difference in growth hormone(p<.001).

This study found that the swimming program had a significant effect on health-related physical fitness and growth hormone in elementary students who did not arrive at puberty. However, although exercise performance may be different according to sex and swimming career, this study did not divide sex and swimming career in the subjects. Therefore, further study should subdivide sex and swimming career to provide a more effective exercise program and measure results more definitely.
