초록

본 연구는 남자초등학교 4학년생 중 태권도 유품자($1{\sim}2$품)로서 태권도칼슘섭취군(8명), 태권도군(8명), 대조군(8명) 총 24명을 대상으로 하였다. 태권도와 칼슘 섭취가 남자초등학생의 체격, 성장호르몬 및 IGF-1에 미치는 영향을 규명하기 위하여 운동 강도 RPE ($7{\sim}15$), 운동빈도 주 5회, 1회 50분의 지속시간으로 12주간 실시하였다. 칼슘은 1일 1회 저녁에 750 mg을 섭취시킨 결과 다음과 같은 결론을 얻었다. 신장은 집단 내 세 그룹 모두 유의하게 증가하였지만 집단 간에서는 대조군에 비해 태권도군과 태권도칼슘섭취군이 유의하게 증가하였다. 성장호르몬은 대조군이 유의하게 감소하였으며 태권도군과 태권도칼슘섭취군은 대조군에 비해 유의하게 증가하였다. IGF-1은 집단 내 태권도군과 태권도칼슘섭취군이 유의하게 증가하였으며 집단 간에서는 대조군에 비해 태권도군과 태권도칼슘섭취군이 유의하게 증가하였다. 이상의 결과를 통해 초등학생에게 태권도프로그램과 칼슘섭취는 신장과 체중, 성장호르몬 및 IGF-1에 긍정적인 영향을 미쳤으며, 향후 적절한 태권도프로그램개발과 운동처방 및 영양섭취에 대한 지속적인 연구가 요구된다.

The purpose of this study was to investigate the effect of Taekwondo and calcium intake on physique, growth hormone and IGF-1 in elementary school male students. 24 subjects who the fourth grade and Taekwondo black belt ($1{\sim}2$ poom) were classified into three groups; Taekwodo +calcium intake group (8), Taekwondo group (8) and control group (8). The period of Taekwondo was 12 weeks, 5 times a week and each time 50 minutes with RPE ($7{\sim}15$) for intensity were treated and subjects were given calcium at 750 mg of pill after dinner a day during the 12 weeks. The conclusions of this study are as follows; In the comparison within each group, three groups all significantly increased in body height but in the comparison between groups, A and B groups were more significantly increased in body height than C. C significantly decreased in growth hormone and in the comparison between groups, A and B groups were more significantly increased in growth hormone than C. In the comparison within each group, A and B significantly increased in IGF-1 and in the comparison between groups, A and B groups were more significantly increased in IGF-1 than C. It is considered that Taekwondo and calcium intake give effects to body height by increasing growth hormone and IGF-1. It is necessary to continue the study, because the study results of growth hormone and IGF-1 are various by training method, intensity, nutrition.
