흡기근육 훈련이 아마추어 축구선수들의 최대 유산소 운동능력에 미치는 영향

초록

The aim of this investigation was to determine the effects ofn sipiratory muscle training(IMT) on maxima l aerobic exercise performance in amateur soccer players. 14 male soccer players were randomly assigned to Inspiratory muscle training group(IMTG, n=7) or Control group(CG, n=7). Both group performed incremental treadmill test using Bruce protocol to examine maximal aerobice xercise performance before and following 8 weeks of intervention. IMTG were given inspiratory pressrue threshold device(POWERbreathe) for IMT . All subjects also completed the winter training programme during the 8 weeks intervention. After intervention,there was significant change in VO2/kg between groups(p=0.006). IMTG showed significant changes in VO2/kg(22.15%, p=0.046), METS(21.53%, p=0.048), VT(22.36%, p=0.035) in measured AT values. There was significant change in treadmill exercise time between groups(p=0.001) and IMTG had significant change in treadmill exercise time(19.26%, p=0.001) after 8 weeks intervention. These results support evidence that inspiratory muscle training(IMT) has beneficial effects on VO2/kg, METS, VT and treadmill exercise time and might be a factor that improve soccer players’ exercise performance.
