Abstract

The purpose of this study was to examine the effect of 16 weeks of resistance training on the fatigue factor, muscle soreness, oxidative stress, and myokine in elite weightlifters. A total of 10 subjects (six male, four female) participated in this study. The results were compared according to baseline, 8 weeks, and 16 weeks. Ammonia and Pi were increased through 16 weeks of resistance training, but this result was not significant. CK was significantly (p<0.05) increased at 8 weeks and 16 weeks compared to baseline, while LDH was significantly (p<0.05) increased at 8 weeks compared to baseline. The MDA of the oxidative stress factor was significantly (p<0.05) increased at 8 weeks compared to baseline and 16 weeks, and TAS of the antioxidant factor was significantly (p<0.05) increased at 8 weeks compared to baseline. The IL-15 of the myokine was significantly (p<0.05) increased at baseline compared to 8 weeks and 16 weeks. In conclusion, 16 weeks of high-intensity resistance training may have a positive effect on peripheral fatigue factors, muscle soreness, oxidative stress, and myokine in elite weightlifters.

본 연구의 목적은 16주 근력 트레이닝을 동반한 TRX, 코어 훈련이 엘리트 역도 선수의 피로물질과 근 손상, 산화적손상, myokine에 미치는 영향을 규명하기 위함이다. 본 연구 대상자들은 총 10명(남 6명, 여 4명)으로 구성되어 있으며 16주 근력 운동과 더불어 코어 및 TRX 트레이닝을 실시하여 다음과 같은 결과를 얻었다. Ammonia와 Pi는 트레이닝 전에 비해 점차적으로 증가함을 나타냈으나 통계적으로 유의한 차이는 나타나지 않았다. 근 손상 물질인 CK는 트레이닝 전에 비해 8주에 유의한(p<0.05) 증가를 나타냈으며, LDH는 트레이닝 전에 비해 8주에 유의한(p<0.05) 증가를 나타냈지만 16주에는 감소하는 경향을 나타냈다. 산화적 손상 지표인 MDA는 트레이닝전과 16주에 비해 트레이닝 8주에서 유의한(p<0.05) 증가를 나타냈으며, 항산화 지표인 TAS 또한 트레이닝 전에 비해 트레이닝 8주에서 통계적으로 유의한(p<0.05) 증가를 나타냈다. Myokine인 IL-15는 트레이닝 전에 비하여 트레이닝 8주와 16주에 통계적으로 유의한(p<0.05) 증가를 나타냈다. 결과적으로 16주 고강도 근력 트레이닝은 엘리트 중학교 역도선수의 피로물질과 근 손상, 산화적 손상, myokine에는 긍정적이 영향을 미친 것으로 나타났다.
