The purpose of this study was to compare lactic acid removal rates during three modes of recovery from a standardized exercise bout. Each subject (N = 6) completed a 1 mile run (92.2 +/- 3.7% Vo2max). Thereafter, lactic acid removal rates were compared in the runners at each of three different modes of recovery: a) rest; b) a self-selected, continuous jogging pace (free-jogging); and c) completely uncontrolled recovery (free-intermittent) normally practiced by athletes. Venous blood samples were taken immediately after the mile run and every 5 min thereafter for 20 min. Data were expressed relative to the initial post-exercise blood sample (100%). Lactic acid removal was significantly faster during the free-jogging recovery than during the free-intermittent and the resting recoveries (P less than 0.001). Removal rates during the free-intermittent recovery were significantly faster than during the resting recovery (P less than 0.001). The results indicated that nearly optimal lactic acid removal rates were attained during the free-jogging recovery.
本研究的目的是比较在标准化运动 bout 后的三种恢复模式下乳酸清除率。每位受试者（N = 6）完成了 1 英里跑（92.2 +/- 3.7%最大摄氧量）。此后，比较了跑步者在三种不同恢复模式下的乳酸清除率：a）休息；b）自行选择的持续慢跑速度（自由慢跑）；c）运动员通常采用的完全无控制的恢复（自由间歇）。在跑完 1 英里后立即采集静脉血样，此后每 5 分钟采集一次，共采集 20 分钟。数据以相对于运动后初始血样（100%）表示。自由慢跑恢复期间的乳酸清除明显快于自由间歇和休息恢复期间（P < 0.001）。自由间歇恢复期间的清除率明显快于休息恢复期间（P < 0.001）。结果表明，自由慢跑恢复期间达到了近乎最佳的乳酸清除率。
