초록
본 연구의 목적은 자기 페이스 조절에 따른 하프마라톤 시 3가지 다른 환경온도 차이가 체내 면역 반응의 하나인 cytokine 변화에 미치는 영향을 살펴보는데 있다. 피험자는 K대학 체육과 재학생 8명으로 하프마라톤을 달리는데 신체적 문제가 없는 이들로 구성되었으며, 피험자는 각각 28℃, 17℃, 12℃인 환경에서 반복하여 트레드밀 위에서 하프마라톤 거리를 달리게 하였다. cytokine을 분석하기 위한 채혈은 운동 시작 전과 종료 직후, 종료 30분 총 3회에 걸쳐 실시되었고, Interleukin-1β와 Interleukin-6가 검사되었다. 검사 결과를 비교․분석하기 위하여 이원반복측정변량분석을 이용하였으며 통계적 유의수준은 p<.05로 설정하였다. 결과적으로 IL-1β는 환경온도 차이에 따른 통계적 차이가 없었으나(p>.05), IL-6는 환경온도 에 따른 통계적 유의성이 나타났다(p<.05). 특히, 고온에서 중온과 저온에 비하여 상대적으로 급격히 증가하는 것을 알 수 있었다. 그러므로 고온에서 오랜 시간 운동 시에는 주의가 요구된다고 하겠다.
Abstract
The purpose of this study was to examine the effects of three different temperatures on changes of cytokine during half marathon performance according to voluntary pace control. Eight students majoring in physical education who were able to run a half distance of marathon and had no health problems were recruited. They ran 20 km three occasions on a treadmill in each of 28, 17, and 12℃ of air temperature. During the tests, their Blood were collected and analyzed by Two-way ANOVA with repeated measure. A significant level were P<.05. Results were as follows; No differences were found in IL-1 β (P>.05), but statistical differences were found in IL-6 (P<.05). It appeared that this response was typical characteristics of cytokine such as acute appearance and discharge as well as inflammatory responses. Based on the results, IL-6 changes during long-distance endurance running were differently influenced by the temperature. This information was warranted such that it could be applied for physical performance of marathon and be utilized for a reference in diverse physical activities and health.
