The purpose of this study was to verify resistance training’s compatibility to bone mineral density, osteocalcin and alkaline phosphatase through comparisons and analyses of difference by groups and grades of N-male’s high school students located in B metropolitan city. The subjects participated in the experiment consisted of male exercise group(n=30) and control group(n=30), who were sampled by each 10 persons from each grade among grade 1, 2 and 3 and who were intentionally selected participants born within±1month(from May to July) of normalized June as the same date of birth in order to keep consistency between groups and grades. The application of resistance training program to the subject was performed according to experimental protocol of 50~60 minute in 3times/week during 8 weeks.The conclusions obtained from the above were as follows;Bone mineral densityThe 3rd grade in the increase of bone mineral density in lumbar total of exercise groups was superior to the 1st, 2nd grade, but there was no significant difference among all grade’s mineral density in femoral neck, trochanter, and Ward’s triangle. However, in main effects among grades and terms, the 3rd grade got better results than the 1st grade at left trochanter and the 1st grade’s got better ones that the 3rd grade’s at left Ward’s triangle. Osteocalcin and Alkaline phosphatase There was no significant difference in the increment among grades of osteocalcin and alkaline phosphatase in exercise group, but the main effects among grades and terms of osteocalcin were large in terms, and there were larger effects of alkaline phosphatase in the 1st grade than those in the 2nd and 3rd grade. Therefore, it is concluded that it was shown to take a positive change in all exercise group. It was shown that the most optimal term of resistance training in bone mass increase of lumbar total of bone mineral density is the 3rd grade and so is the 1st grade in alkaline phosphatase of bone metabolism.

본 연구는 중학생의 전신 지구력과 혈중지질의 관계를 분석하기 위하여 중학교 1학년 남녀 학생 400명을 대상으로 오래달리기(남자 중학 1,OOOm 달리기, 여자 중학 800m 달리기)를 실시하여 기록이 상(1∼10%) · 중(45∼55%) · 하(91∼100%)의 각각 10%에 해당하는 학생 총 120명을 연구대상으로 분석한 결과, 전신 지구력과 혈중 지질의 관계에서 TC, TG, LDL-C, AI는 남녀 모두 유의한 정적 상관, HDL-C는 유의한 부적 상관이 있는 것으로 나타났다. 또한, 전신 지구력에 영향을 미치는 요인은 남녀 모두 TG인 것으로 나타났다. The purpose of this study was to analyse the relationships between endurance and blood lipid of 1st grade in middle school, and to produce the correlation between endurance and blood lipid. For that purpose, we carried out the long distance runnings(the 1,000m running for the 1st grade boys in middle school, and the 800m running for the 1st grade girls in middle school) and arranged their records in ordinal scale. After that, we selected upper 10 percent(1∼10%), middle 10 percent(45∼55%), and lower 10 percent(91∼100%) as subjects of this study(n=120). The results obtained by this study were as follow : 1. Correlation between Endurance and Blood Lipid. There was positive correlation between endurance and TC, TG, LDL-C, and AI, but negative correlation in HDL-C on 1st grade in middle school. 2. Factors That Influence Endurance In blood lipid, TG was the factor on 1st grade girls in middle school.
