【摘要】 本文比较了各种无氧阈测值:通气阈（VT）,4mmol乳酸阈（LT₄）,血乳酸开始升高(LT_OBLA),个体无氧阈（IAT）,血乳酸最大稳态（maxLass）和心率拐点（HRd）。发现各测值之间高度相关,但是maxLass与其它测值之间存在不同程度的差异,为AT在训练中的应用提供了有价值的生理依据。继而探讨了LT₄百分比强度对控制中长跑训练,改善运动员肌肉氧化代射能力,提高运动成绩的意义。更多还原

【Abstract】 Different testing methods of anaerobic threshold（AT）,including ventilatory threshold（VT）,lactate threshold in 4mmol （LT4）,LT_（OBLA）,individual anaerobic threshold（IAT）,maximal lactate steady state（maxLASS）,and heart rate break point （HR-AT）, were compared in this study with 90 middle-and long-distance runners and 15 cyclists served as objects. The results revealed that there were high correlations between the values of different AT（r=0. 88-0. 96） ,and there exist differences between AT values and maxLASS. From longitudinal study it was found that endurance training with intensity of 85 -90% LT4 （BLa2-4mmol）and total load of 50-60% could significantly improve both AT values and endurance performance of distance runners.更多还原
