김강훈(KangHunKim),양점홍(JumHongYang),최재현(JaeHyunChoi) 한국체육학회 2006 한국체육학회지 Vol.45 No.4

이 연구는 weight training시 보다 효율적인 1RM 재설정 시기를 제시하는데 목적이 있다. 남자고등학교 2학년 학생을 1RM 재설정 시기를 기준으로 A(1주), B(2주), C(3주), D(4주) 그룹, 각 10명씩 총 40명을 유의 추출하여 12주간, 주 3회 55~70분간 70~80%RM의 weight training을 실시하여 각 그룹내·간의 시기별 변화율을 비교한 결과, bench press, squat, dead lift는 모두 그룹 내 운동 전·후 향상되었으며, 그룹 간 비교에서는 2주, 3주, 4주마다 1RM 재설정 그룹이 1주마다 1RM 재설정 그룹보다 향상되었다. testosterone은 그룹 내·간, 운동 전·후 차이가 없었다. CPK는 그룹 내 운동 전·6주 후 2주, 4주마다 1RM 재설정 그룹에서 감소하였으며, 그룹 간에는 차이가 없었다. 따라서 남자고교생의 WT 프로그램에서 1RM 재설정 시기가 testosterone, CPK에는 영향을 미치지 않았으며, 최대근력 향상 면에서는 2~4주의 1RM 재설정 시기가 효과적인 것으로 본다. The purpose of this study was to investigate more effective 1RM resetting time in WT program after comparative analysis of 1RM, testosterone, and CPK variations in male high school students. Forty subjects participated in this study from P high school in B metropolitan city. The subjects were grouped according to A(1week), B(2weeks), C(3weeks), and D(4weeks) on 1RM resetting time respectively in weight training period. The application of WT program for 12weeks was performed according to 55~70minutes per day, 3times a week, 70~80%RM, 8~12 repetitions, and 3sets. The detailed results of this study were as follows; 1) 1RM of bench press, squat, and dead lift between pre-exercise and post-exercise were all significantly improved in intragroup. 1RM resetting group of 2weeks, 3weeks, and 4weeks each in intergroup comparison were significantly improved better than 1RM resetting group of each week. 2) There was no significant difference in testosterone between intragroup, and intergroup, pre-exercise, and post-exercise. 3) The group was controlled 1RM resetting in pre-exercise and 2weeks, 4weeks each after 6weeks was significantly decreased in CPK, and there was no significant difference among each group. In conclusion, these results indicated that 1RM resetting time in WT doesn't lead to testosterone and CPK variations in male high school students, but 1RM resetting time from 2 to 4 weeks is effective on improvement of maximal strength.
