摘要: | 本研究目的在比較不同運動類型(速度型和耐力型)之受試者,在不同模式(120% VO2 max, 90rpm和40N負荷,全力衝刺)下進行2-3分鐘之超最大運動對最大累積缺氧量(maximal accumulated oxygen deficit, MAOD)之影響。受試者為大學體育系田徑隊男生共20名(速度型10名;耐力型10名),每位受試者均需接受一次VO2 max、四次非最大運動測驗 (40%、55%、70%、85% VO2 max, 60rPm,持續運動8分鐘)、二次2-3分鐘之超最大運動測驗(120% VO2 max, 90 rpm和40N負荷,全力衝刺)、400m測驗及人體測量等。所有資料以混合設計雙因子變異數分析之,a=.05。所得結果顯示:(一)不論是以何種全力運動負荷模式(120% VO2 max, 90 rpm或40N,全力衝刺),速度組受試者測得之最大累積缺氧量值均顯著的高於耐力組;此外,耐力組在Medbφ妙傳統法下所測得的MAOD值會顯著的高於在40N新方法下所測得之值,但在速度組貝憮運動負荷模式之差異存在。(二)在從事2-3分鐘超最大運動時,40N方法(40N,全力衝刺)較Medb φ妙傳統法(120% VO2 max, gorpm)更能鑑別出速度組與耐力組之MAOD差異性。
The purpose of this study was to investigate the effects of 2-3 minutes of supramaximal exercise under different modes (120% VO2 max, 90 rpm and 40N load, full strength) on the maximal accumulated oxygen deficit (MAOD) of subjects who compere in different sports (sprint-type endurance-type). The sebjects were 20 male members of a university physical education department track and field team (10 in the sprint-type speed group; 10 in the endurance-type group). Each subject completed a VO2 max, four submaximal exercise tests (8 mm of 40%, 55%, 70% and 85% VO2 max, 60 rpm, all out sprint), two supramaximal exercise tests (2-3 mill of 120% VO2 max, 90 rpm or 40N load, full effort), a 400 M test and anthropometry in measurements. All data were analyzed by two-way ANOVA at the significance level of a = .05. Results showed that (1) No matter what kind of maximal exercise mode (120% VO2max, 90 rpm or 40N load, full strength), the MAOD of the sprint group was significantly higher than that of the endurance group; in addition, the MAOD of the endurance group derived by the Medbφ traditional method was significantly higher than that by the 40N new method. (2) For 2-3 minutes of supramaximal exercise, the 40N method (40N, full effort) was better than the Medbφ traditional method (120% VO2 max, 90 rpm) to identify the difference between the sprint group and the endurance group. |
