본 연구는 고등학교 엘리트 태권도선수들의 겨루기 상황에서 혈중젖산 농도의 변화와 심박수 수준, 체력요인 간의 관계를 분석하여 선수들의 훈련프로그램 구성과 훈련 평가자료로 활용하여 선수들의 경기력 향상에기여하는데 연구의 목적이 있다. K지역 체육전문 고등학교 태권도선수 30명(남 18명, 여 12명)을 대상으로체격 요인과 근 기능, 무산소성파워를 평가 후 겨루기 라운드별 혈중젖산의 변화와 심박수 수준을 비교⋅분석하였다. 통계적 유의수준은 p<.05로 하였다. 연구 결과 무산소성파워와 심박수 수준, 혈중젖산농도 변화에서는성별에 따른 차이는 없었고, 겨루기 경기 승⋅패, 근 기능 수준, 무산소성파워 수준에서는 비교그룹 간의차이가 나타나지 않았다. 남자 선수는 체지방률에 따라 혈중젖산 농도의 통계적 유의한 차이가 나타났다(p<.01). 심박수 수준에 따른 혈중젖산과의 상호관계는 남자 선수만 Zone 3에서 운동직후의 혈중젖산 변화와유의한 관계가 나타났다. 태권도선수의 체지방률이 혈중젖산변화와 관련이 있었으며, 또한 근 기능과 무산소성파워가 시합상황에서 혈중젖산에 영향을 미치는 경향이 나타났다. 이러한 연구 결과는 태권도 겨루기선수들의 적절한 체지방률 관리와 함께 근력, 유⋅무산소성체력요인을 위한 훈련프로그램 구성이 요구된다.
Abstract
heart rate, and physical fitness factors in high school elite Taekwondo athletes’ competitive situations, and use them as basic data for evaluating athletes’ training program composition and training. After evaluating the pyhsical fitness factors(muscle function, anaerobic power) for 30 athletes (18 males and 12 females) from High School, the changes in blood lactate and heart rate levels were compared and analyzed for each round of competition. The statistical significance level used was p<.05. As a result of the study, there were no differences between the comparison groups in terms of win/loss, muscle function level, and anaerobic power level in the competition. However, there was a significant difference in blood lactate according to the high and low body fat percentage in male athletes (p<.01). Body fat percentage affects changes in blood lactate in Taekwondo athletes, and muscle function and anaerobic power tend to have a positive effect on blood lactate in competition. results of this study, body fat management and improvement of muscular strength and anaerobic power of athletes is required.
