초록
본 연구에서는 주짓수 대회 성인 부문 참가 경험이 있고, 주짓수 수련경력 1년 이상 흰 띠 남성 8명을 대상자로 선정하여 토너먼트를 가정한 고강도의 스파링을 총 3라운드 실시하였다. 각 라운드 스파링 후 휴식시간 동안 심박수의 회복 경향을 알아보기 위해 각 라운드별 직전, 직후, 30초, 1분, 2분, 3 분, 4분, 5분의 심박수를 측정하였고, 각 라운드 직전 심박수 수준을 100% 하여 휴식시간 증가에 따른심박수 회복률(Heart Rate Recovery: HRR)을 %로 나타내었다. 이원분산분석에 따른 사후비교 결과, 1, 2라운드 스파링 직후 심박수는 하위포지션에서 높게 나타났으며, 30초부터 5분까지 유의하게 낮게나타났다(p<.05*, p<.043*). 그러나 3라운드에서는 스파링 직후에서 5분까지 하위포지션이 낮게 나타나는 경향을 보였으나 유의한 차이는 나타나지 않았다. 1, 2, 3라운드 심박수 회복률은 동일한 휴식시간에서 하위포지션이 빠르게 감소하는 경향을 나타내었다. 따라서 선수들의 안정시 심박수 수준과 유산소 능력은 주짓수 토너먼트 경기에서 경기력을 예측할 수 있는 중요한 요인이라 생각된다.
Abstract
Eight white belt men who participated in the Jujitsu tournament adult division with at least one year of Jiujitsu training were selected as subjects, and they were subjected to a total of three rounds of high-intensity sparring assuming tournaments. To determine the recovery tendency of heart rate during each round of rest after each round sparring, heart rate was measured immediately, immediately after each round, 30 secs, 1 min, 2 min, 3 min, 4 min, and 5 min of heart rate recovery (HRR) was 100% before each round. The post-hoc comparison results of the two-way ANOVA showed that the heart rate was high in the bottom position immediately after the first and second round sparring, and significantly low from 30 seconds to 5 minutes (p<.05*, p<.043*). However, in the third round, the bottom position showed a low tendency from the sparring to the 5 minutes, but there was no significant difference. The recovery rate of heart rate in the first, second and third rounds tended to decrease rapidly in the bottom position at the same break time. Therefore, players’ heart rate levels and aerobic abilities during stability are considered important factors to predict performance in Jiujitsu tournaments.
