초록
본 연구는 Wingate 무산소성 운동능력 검사를 위해 이용되고 있는 기계식과 전자기식 자전거 에르고미터 이용의 타당성을 검증하는데 그 목적이 있다. 본 연구의 대상자는 한국경륜공단소속 선수 13명을 대상으로 각 기기 당 1주일 씩 2회 반복 총 2주간 검사를 하였고 측정 시 부하는 체중×0.8Nm로 30초간 측정하였다. 반복 측정의 차이와 기기 간의 차이를 검증하기 위해 two way RM(2×2)ANOVA를 이용하였고 타당성을 검증하기 위해 LOA%를 분석하였다. Wingate 검사결과 두 기기내의 반복된 검사와 기기간 피크파워 비교결과는 1차에 비해 2차가 평균값이 높았고 상호작용 효과가 있었다(p<.05). 그러나 기계식에서 평균파워와 피크타임도달시간, 피로지수결과는 2차에 비해 1차가 평균적으로 높았고, 두 기기 간에 유의한 차이는 없었다. 두 기기내의 반복측정의 LOA% 결과는 피크파워(기계:8.1, 전자기:8.1), 체중당 피크파워(기계:5.1%, 전자기:3.3%), 평균파워(기계:8.5%, 전자기:5.6%), 체중당 평균파워(기계: 3.7%, 전자기:4.7%), 피크파워도달시간(기계:4.1%, 전자기:6.01), 피로지수(기계:10.65%, 전자기:11.77%)가 LOA 95%의 신뢰구간인 3-29%신뢰구간에 속해있어 반복측정 내에서 차이가 없는 것을 알 수 있었다. 두 기기간의 LOA% 결과는 피크파워(4.6%), 체중당 피크파워(2.7%), 평균파워(5.5%), 체중당 평균파워(3.2%), 피크파워도달시간(2.7%), 피로지수(7.76%) 모두 LOA 95% 신뢰구간인 3-29%에 속해있어 두 기기 간에 차이가 없었다. 이러한 결과로 볼 때, wingate 무산소성 운동능력 측정을 하기위해 사용되고 있는 기계식과 전자기식 에르고메터 결과는 LOA% 신뢰오차범위 3-29%내에 모두 속해있어 wingate 무산소성 운동능력측정에 타당성이 있는 것을 알 수 있었다.
Abstract
The purpose of the study was to compare measured errors of two different types of ergometers (mechanically and electro-magnetically braked cycle ergometer) to measure anaerobic exercise abilities of thirteen professional cyclists who has registered with the Cycle Racing Corporation. All the cyclists participated in four tests for two weeks to measure WAnT(two test days for each ergometer for a week). On each day, the test lasted for 30 seconds with a workload of 0.8Nm/kg. The first value of Peak Power(PP) was lower than from the second. When two ergometers were compared, the PP of the mechanically braked ergometer showed higher than those of the electro-magnetically braked. Mean Power(MP), Time To Peak Power(PPAT) and Fatigue Index(FI) of the second test on the mechanically braked ergometer showed higher values than those of the first test, but no significant difference between the two tests was observed. When two ergometers were compared, the values of MP, TTPP and FI of the mechanically braked ergometer showed higher than those of the other ergometer, but no significant difference was found. Systemic errors of repeated measurements of PP, PP per kg, MP, MP per kg, TTPP and FI on the mechanically braked ergometer were 8.1%, 5.1%, 5.7%, 4.7%, 6.0% and 11.8% respectively. Systemic errors measured from the electro-magnetically braked ergometer resulted in PP (8.1%), PP per kg(3.3%), MP(8.6%), MP per kg(3.6%), TTPP(4.1%) and FI (10.7). From these results, it can be concluded that there was no different within two tests of each ergometer. The systemic errors between the two ergometers also showed no difference: PP(4.6%), PP per kg(2.7%), MP(5.5%), MP per kg(3.2%), PPAT(2.7%) and PI(7.76%). Therefore, it may be recommended that, for more accurate measurement of anaerobic exercise ability, the electronically-braked cycle ergometer be used although the validity between these two ergometers showed no difference.
