中文摘要 |
Purpose: this study investigated the effects on the antioxidant defense system during acute bouts of high-intensity interval training and tried to quantify this kind exercise. Method: Seventeen healthy males (21.5±1.5 yr.; 65.4±8.9 kg; 18.0±5.2% body fat) were given an interval training exercise. The exercise protocol included three different distances: 200 M, 150 M, 120 M. Subjects must finish three sprints in each distance and maintain 85-90% HRmax reserve. The runners had fifteen minutes rest between different distances and three minutes rest after each sprint. Venous samples were obtained prior to exercise and within fifteen minutes after. Blood from all groups was analyzed for SOD, GSH-Px, t-GSH, TAA, MDA. The t-test repeated measurement was used for data analysis. Results: For subjects who performed the above training exercise results were 5.85 m/sec, 180 beat/min, RPE 7.9, blood lactate 12.6 (mM/L), all significant increases compared to pre-exercise levels (p<.05). The difference was from -26.1% to +32.4% in all, and MDA was increased 0.12 (32.4%) mmol/ml, which was significantly different after exercise (p<.05). Conclusions: Evidence indicated that acute bouts of interval-training induced oxidative stress. We also succeeded in quantifying this exercise pattern, including exercise intensity, distance, frequency and rest time. |
