일회적 운동에서 기능성 핫슈트 착용이 체중감량과 에너지 소모량 및 운동효율성에 미치는 영향
Effects of wearing functional hot suit on weight loss, energy expenditure, and exercise efficacy at acute exercise
The purpose of this study is to determine effects of functional property of wearing hot suit with reinforced moisture permeability on energy expenditure and exercise fatigue changes. Eleven athletes from Korean wrestling team of Y University in Kyungki-do participated in this study. All experimental procedures were conducted in a laboratory under 50-55% relative humidity and 24-25°C room temperature condition. Prior to this study experiment, VO2max of all participants was calculated for exercise intensity set-up through pre-test followed by ACSM protocol. They conducted exercise under 65% VO2max with 30 mins wearing hot suit and wearing general polyester suit without moisture permeability three times each. Weight loss, energy expenditure, blood lactate level, and subjective exercise intensity were measured and compared. There was significant difference in weight loss for wearing hot suit compared to general polyester suit (p<0.05). There was significantly higher exercise efficacy and total energy expenditure in hot suit compared to general polyester suit (p<0.05). Energy expenditure change at each exercise section was significantly higher in general polyester suit and hot suit compared to non wearing suit. Moreover, there was significantly higher energy expenditure in wearing hot suit compared to general polyester suit. Subjective exercise intensity changes showed that there was no interaction among suits and increased exercise time; however, wearing hot suit showed lower subjective exercise intensity changes at each exercise section compared to general polyester suit. Effects of wearing general polyester suit on blood cholesterol change was higher than wearing hot suit (p<0.01); however, there was no significant difference in wearing hot suit and not wearing suit. In conclusion, it can be expected to have positive effect of wearing hot suit on maximizing diaphoretic effect and decreasing psychological stability and fatigue.

현대사회에 있어서 신체활동 연구의 주요 탐구과제는 ‘신체활동을 통한 교육’으로부터 ‘인간의 기본적인 움직임’을 목표로 하는 스포츠적인 움직임을 중심으로 한 생명 활동의 개념으로 급속히 변화되고 있는 추세이다. 이러한 환경변화에 대응하기 위하여 본학회는 ‘체육’적인 요소에서 ‘스포츠’적인 요소를 중심으로 한 학문적 정체성을 견고히 하고, 정기적인 학술지 발간과 학술활동을 통해 한국스포츠츠 문화의 발전과 학문적인 발전에 기여하는데 그 목적이 있다.
