After a standardized 6-min bicycle ergometer exercise (89% VO2max) lactic acid removal rates were compared during recovery at rest and exercies at 29.7, 45.3, 61.8, and 80.8% VO2max, and twice while the subjects (N = 7) regulated their own recovery exercise. Blood samples were taken after the standardized exercise and every 5 min during the 30-min recovery periods. During the controlled recovery periods lactic acid removal rates were dependent on the intensity of the recovery (Y' = 0.103 + 0.218chi - 0.464 X 10(-2)chi2 + 0.252 X 10(-4)chi3). Optimal removal was predicted to occur at 32% VO2max. Removal rates during the self-regulated recoveries were not different (P greater than 0.05), but these removal rates were faster than during recovery at rest and exercise at 61.8 and 80.8% VO2max (P less than 0.01). Removal rates during the self-regulated recovery and recovery at 29.7 and 45.3% VO2max were not different (P greater than 0.05). The subjects were therefore able to remove lactic acid effectively when selecting their own recovery exercise.
在进行标准化的6分钟自行车测力计运动（89%最大摄氧量）后，比较了在静息恢复以及在29.7%、45.3%、61.8%和80.8%最大摄氧量运动恢复期间的乳酸清除率，并且在受试者（N = 7）自行调节恢复运动时有两次这样的比较。在标准化运动后以及30分钟恢复期间每5分钟采集血样。在受控恢复期间，乳酸清除率取决于恢复强度（Y' = 0.103 + 0.218χ - 0.464×10⁻²χ² + 0.252×10⁻⁴χ³）。预计在32%最大摄氧量时出现最佳清除。自行调节恢复期间的清除率没有差异（P大于0.05），但这些清除率比静息恢复以及在61.8%和80.8%最大摄氧量运动恢复期间更快（P小于0.01）。自行调节恢复以及在29.7%和45.3%最大摄氧量恢复期间的清除率没有差异（P大于0.05）。因此，受试者在选择自己的恢复运动时能够有效地清除乳酸。
