Eleven male subjects were studied during graded leg exercise from 60 to 270 W. Arterial and venous lactate concentrations were measured from the resting forearm during the exercise and recovery periods. Lactate concentration rose regularly during the work and declined slowly to basal levels after the exercise. The arteriovenous difference rapidly became positive during the exercise, indicating a net uptake of lactate by the nonexercising muscles. The uptake of lactate by the muscle correlated directly with the arterial concentration. After the 5th min of recovery, there was no longer any significant difference between arterial and venous lactate concentrations. It is concluded that 1) nonexercising muscles play a small role in the removal of lactate during exercise and 2) significant removal of lactate from the blood by nonexercising muscles stops soon after the cessation of exercise.
对11名男性受试者进行了从60瓦到270瓦的分级腿部运动研究。在运动和恢复期间，测量了静息前臂的动脉血和静脉血乳酸浓度。运动期间乳酸浓度有规律地上升，运动后缓慢下降至基础水平。运动期间动静脉差值迅速变为正值，表明非运动肌肉对乳酸有净摄取。肌肉对乳酸的摄取与动脉血浓度直接相关。恢复5分钟后，动脉血和静脉血乳酸浓度不再有任何显著差异。研究得出结论：1）非运动肌肉在运动期间对乳酸清除所起的作用较小；2）运动停止后不久，非运动肌肉从血液中显著清除乳酸的过程就停止了。
