摘要
为了调查短期高强度训练对篮球运动员有氧耐力的影响 ,对 2 0名 (男、女各 10名 )优秀篮球运动员 ,进行跑台渐增负荷运动直到力竭为止。同时测定气体代谢最大吸氧量 (VO2max)、通气量 (VE)、血乳酸(BLa)、心率 (HR)、血睾酮 (T)、皮质醇 (Cor)及血红蛋白 (Hb)。结果为 :1)短期高强度训练期后男、女两组无氧阈 (AT)值与训练前相比较均有显著性差异 (P <0 .0 5 ) ,但VO2max却未有显著性差异 ;2 )短期高强度训练期后男、女两组Hb值与训练前相比较均有显著性差异 (P <0 .0 5 ) ,而T、Cor在训练期前后却未有显著性差异。其结果表明 ,短期高强度训练并不能提高VO2max,而AT却明显提高。提示可采用AT值作为反映篮球运动员有氧耐力的指标。
To observe the effects of intense exercise on aerobic endurance after intense exercise, 20 basketball players were divided into two groups as follows: 10 male basketball players athletes, 10 female basketball players athletes. Oxygen consumption (VO 2), pulmonary (VE), blood lactate (BLa), heart rate (HR), T(testosterone),Cor (cortisol) and Hb (hemoglobin) were obtained during an incremental exercise test to exhaustion on a treadmill for 20 subjects. The results were as follows: 1) The ATs (anaerobic thresholds) were increased significantly after exercise in two groups than that in before exercise, but not their VO 2.2) The Hbs were increased significantly after exercise in all groups than that in before exercise, whereas T and Cor were not significant different between before and after exercise. It is concluded that the level of VO 2max can be kept by this intense exercise. The AT (anaerobic threshold) may play an important role in aerobic endurance exercise.
