Abstract

This study proposes an efficient weight training strategy to reduce body fat, by identifying the effects of weight training on body fat reductions based on individual characteristics and changes in skinfold thickness. We analyzed the effects of 12-weeks weight training on changes in skinfold thickness and the resulting body fat reductions by considering individual traits of the subject. Our results indicate that individual characteristics have no statistically significant effects on changes in skinfold thickness, but were statistically significant for changes in the amount of body fat. Second, changes in skinfold thickness showed statistically significant effects on changes in body fat. Third, weight training induced changes in skinfold thickness were more significant in men than in women. Men also exhibited greater changes in body fat than women after weight training. Taken together, these findings confirm that changes in skinfold thickness and body fat observed through the 12-week weight training had variations depending on individual characteristics, and changes in skinfold thickness significantly affect the changes in body fat. The weight training program proposed by this study considers incorporation of individual characteristics, rather than accomplishing the same outcome with uniform methods and amounts of training. Furthermore, this program induces changes in skinfold thickness before implementing random efforts for reducing body fat.

본 연구는 12주간 웨이트트레이닝에 의한 체지방 감소가 개인적인 특성과 피부두겹의 변화 등에 어떠한 영향을 미치고 있는지를 분석하여 보다 효과적인 웨이트트레이닝 전략을 제안한 연구이다. 분석결과 첫째 개인특성이 피부두겹의 변화에 유의한 영향을 미치지 않았으나 체지방 변화에는 높은 수준의 영향을 미치는 것으로 나타났다. 둘째, 피부두겹의 변화는 체지방 변화에 통계적으로 유의한 영향을 주었다. 셋째, 웨이트트레이닝에 의한 피부두겹의 변화는 남성이 여성에 비해 상대적으로 높은 변화수준을 보였다. 체지방 변화에 있어서도 남성이 여성에 비해 높은 변화를 보이는 것으로 나타났다. 본 결과를 종합하면 12주간의 웨이트트레이닝을 통해 나타난 피부두겹과 체지방의 변화는 개인특성에 의해 수준의 차이가 존재하고 있으며, 피부두겹의 변화는 체지방 변화에 높은 수준의 영향을 미치고 있음을 확인할 수 있다. 이는 본 연구의 웨이트트레이닝 프로그램은 획일적인 방법과 양으로 같은 성과를 나타내려는 노력보다는 개인특성에 맞는 웨이트트레이닝의 시간, 양, 수준을 고려한 규칙적인 웨이트트레이닝 프로그램을 실시한다면 현대인의 비만 문제를 해결하고, 건강관련 체력을 향상시키는데 보다 긍정적인 영향을 미칠 것으로 생각된다.
