이 연구는 Weight training(WT) 실시방법에 따른 1-RM과 신체조성 및 젖산탈수소효소에 미치는 영향을 비교ㆍ분석하였다. 남자고등학생 16명을 대상으로 2그룹(A type ; 3 sets를 연속적으로 한 종목에 실시, B type ; 한 종목 운동 1 set 한 후 다음 종목 1set 실시)으로 구분하였으며, 운동처방은 8주간, 주 3회, 1일 60-70분, 70-80%RM(8-12 reps×3 set)으로 설정하였다. 모든 통계처리는 SPSS 11.0 package를 이용하여 기술통계는 평균값과 표준편차로 나타냈고, 독립변인들에 대한 처치효과는 two-way ANOVA를 사용하여 분석하였고, paired t-test는 집단내 사전ㆍ사후의 평균값 차이 검정을 위해 실시하였다. 분석한 결과 다음과 같은 결론을 얻었다. 1-RM은 A type은 bench press, dead lift, squat, arm curl에서, B type은 bench press, dead lift, squat, shoulder press, arm curl에서 향상되었다. 신체조성은 %fat, FFM에서 집단 내ㆍ집단 간 차이가 없었다. Lactate dehydrogenase(LDH)는 1) 사전 운동직전ㆍ직후에는 차이가 없었으며, 사후 운동직전보다 직후에 증가가 나타났다. 2) 사전ㆍ사후 집단 간에는 차이가 없었다. 3) 사전ㆍ사후 운동직전에서는 긍정적으로 감소하였다.

The purpose of this study was to examine the effects of WT on 1-RM, body composition and LDH according to method of WT in male high school students. Sixteen subjects participated in this study from G high school in B metropolitan city. Participants were randomly selected among third grade students and divided into two groups, A type exercise group{(1 exercise×8-12 rep.×3 sets)×5 exercises, n=8}, B type exercise group{(1 exercise×8-12 rep.)×5 exercises×3 sets, n=8}. The group conducted WT programs consisting of 70-80%RM(8-12 reps×3 sets), 60-70 minutes a day, 3 days per week for 8 weeks. The conclusions obtained from the above were as follow: 1. 1-RM : A within group comparison revealed that A type significantly improved bench press, dead lift, squat and arm curl. And B type significantly improved bench press, dead lift, squat, shoulder press, arm curl. 2. Body Composition : A within and between group comparison were not significant % body fat, FFM. 3. LDH : 1) A between group comparison were not significant before and after exercise of pre test, but It significantly increased after exercise more than before exercise of post test. 2) A between group comparison were not significant pre and post test. 3) A within group comparison revealed a positive reduction before exercise of pre and post test.
