Subjects were fifteen male students with average age, height and weight of 22.0For attaining VO2max, each subject performed a maximal cycling test with progressively increased workloads. Immediately following maximal exercise of 110% VO2max on the bicycle ergometer, all subjects randomly performed one of the recovery treatments, a static rest or a motor driven exercise. Expired air was determined by Sensormedics 2900 metabolic system. 　　Blood samples for determination of lactate concentration were taken at rest, 5th and 15th minute after maximal exercise from an indwelling venous catheter. Data were analyzed by repeated measure analysis of covariance, the results included: 　　1. Recovery heart rates 5th, 10th minute following motor-driven exercise were significantly higher than those of static recovery. 　　2. Ventilation and oxygen uptake 5th, 10th and 15th minute following motor-driven exercise were significantly higher than those of static recovery. 　　3. Blood lactate removal rate following 15minutes of motor-driven exercise was significantly faster than that of static recovery. 　　The results revealed that motor driven recovery maintained higher levels of recovery ventilation, oxygen uptake and heart rate, and thus increase the blood lactate removal rate. Such an elevation in physiological responses may shorten recovery period and improve recovery efficiency following severe physical exercise.
