본 연구는 해양 폴리페놀 복합 음료(Marine polyphenol mixed drinks, MPMD) 섭취가 역도선수들의 체간 근기능(Trunk muscle function, TMF)에 어떠한 영향을 미치는지 구명하고 경기력 향상을 위한 기초자료로 제공하는데 목적이 있다. 연구의 대상자는 20명의 서울 소재 K 대학교 남자 역도선수들로 진행하였으며, 집단 선정은 무작위 배정방식으로 MPMD 집단 10명, 통제 집단 10명씩 선정하였다. 사전 측정은 체성분 분석과 TMF 측정 순으로 진행하였으며, 1주일간의 휴식 후 동일한 방법으로 사후측정을 진행하였다. 사후 측정 시 MPMD집단의 경우 측정의 오류를 최소화하기 위해 체성분 분석 이후 MPMD를 섭취하고 30분의 휴식 후 TMF 측정을 실시하였다. 섭취 유무에 따른 집단 및 시기 간의 차이를 비교 분석하기 위해 이원변량 반복측정 분산분석을 실시하였으며, 모든 통계의 유의수준은 α=.05로 설정하였다. 30°/sec 체간 굽힘과 폄의 최대 우력에서 MPMD집단에서만 통계적으로 유의하게 증가한 것으로 나타났으며(p<.05; p<.05), 폄의 최대우력에서는 집단 및 시기에 따른 상호작용 효과에서도 통계적으로 유의한 차이가 있는 것으로 나타났다(p<.05). 60°/sec 체간 폄의 최대우력에서 집단 및 시기에 따른 상호작용 효과에서 통계적으로 유의한 차이가 있는 것으로 나타났다(p<.05). The purpose of this study is to provide basic data on how marine polyphenol mixed drinks(MPMD) intake affects the trunk muscle function(TMF) of weightlifting athletes(WA) and to improve performance. The subjects of the study were WA(N=20) from Seoul K University, and the group selection was Randomization by MPMD group(n=10) and control(no intake, CON) group(n=10). Pre-measurement was conducted in the order of body composition analysis and TMF measurement, and post-measurement was carried out in the same way after a 1 week's rest. In the case of MPMD group for post-measurement, MPMD was ingested after body composition analysis and TMF measurement was performed after 30 minutes of rest to minimize measurement error. Two-way repeated measure ANOVA was performed to compare the differences in TMF according to the presence or absence of intake between groups and time, and the significance level of all statistics set was α=.05. There was a statistically significant increase in the peak torque of 30°/sec trunk flexion and extension(p<.05; p<.05) in only the MPMD group, the peak torque of trunk extension also showed statistically significant differences in group×time interaction effects(p<.05). There was also a statistically significant difference in the effects of group×time interaction effects at the peak torque of 60°/sec trunk extension(p<.05).

본 연구는 엘리트 복싱 선수들의 고중량 바벨 준비운동이 근파워, 민첩성 및 협응력에 미치는 영향을 검증하기 위해 실시하였다. 연구 대상은 최근 1년 이내에 신체의 상해나 병력이 없고 선수 경력이 5년 이상이며, 웨이트 트레이닝을 지속적으로 실시해온 대학교 엘리트 복싱 선수중 총 21명을 대상으로 하였다. 실험 전 4분간의 유산소 운동을 공통적으로 실시한 후에 사전 측정을 실시하였고, 일주일 간격으로 2회로 나누어 검사를 실시하였다. 첫째 날에 총 21명을 무처치군(N=10)과 고중량 바벨 준비운동군(N=11)으로 임의 배정하여 진행 후 일주일 후에 반대로 무처치군(N=11)과 고중량 바벨 준비운동군(N=10)으로 진행하였다. 고중량 바벨 준비운동은 1RM의 80% 무게에 세트 사이 휴식시간 3분으로 Barbell Squat와 Barbell Bench Press를 3회 3세트 실시한 후 4분 후에 테스트를 진행하였다. Vertical-Jump test, Long-Jump test, Side-step test, T-run test 및 Sit up & Throw test를 이용하여 근파워, 민첩성 및 협응력을 측정하였다. 고중량 바벨 준비운동 적용에 따른 민첩성(T-run, Side step) 차이를 비교 분석한 결과 통계적으로 유의한 차이가 나타났으며(p<.001), 근파워(Vertical Jump, Long Jump), 협응력(Sit-up & Throw)의 집단 간 차이는 통계적으로 유의한 차이가 없는 것으로 나타났다. 고중량 바벨 준비운동을 통해 민첩성의 단기적 향상에 효과적임이 증명되었다. This study was conducted to verify the impact of heavy-weight barbell warm-up exercise on muscle power, agility and coordination among elite boxers. The study included a total of 21 elite boxers from universities who have no physical injuries or medical history within the past year and have more than five years of experience as a player, and have continued weight training. In the experiment, the warm-up was conducted after a common four-minute aerobic exercise, and the test was conducted in two days. On the first day, a total of 21 people were randomly assigned to the Control group(N=10) and the Heavy-Weight Babell warm-up group(N=11), and a week later, the other way around, the Control group(N=11) and the Heavy-Weight Babell warm-up group(N=10). The heavy weight barbell warm-up was tested four minutes later after three sets of barbell squats and barbell bench presses were performed three times with a three-minute break between sets weighing 80% of the 1RM. Muscle power, agility, and coordination were measured using the Vertical-Jump test, Long-Jump test, Side-step test, Ability T-run test, and Situp & Throw test. Comparative analysis of the differences in agility(T-run, Side step) due to the application of high-weight barbell warm-up showed statistically significant differences(p<.001), and there was no statistically significant difference between groups of muscular power(Vertical Jump, Long Jump) and coordination(Sit-up & Throw). High weight barbell warm-up has proved effective in improving agility in the short term.
