本研究的目的在探討激烈運動後，靜態恢復與馬達驅動式恢復對恢復心跳率、換氣量、耗氧量及乳酸排除率的影響。受試者為15名體育系所男學生，平均年齡為22.0± 2.5歲，身高173.3 ± 5.5公分，體重71.5 ± 6.4公斤。所有 受試者須先測量個人的最大攝氧量並求出衰竭運動強度(110%V02m缸) ，爾後依平衡次序，在衰竭運動後分別接受一次馬達驅動式恢復及一次靜態恢復。實驗過程中以Sensormedics2900型能量代謝系統採氣分析，並由無線電心電 圖計紀錄心跳率。同時在安靜時、衰竭運動後第5、15分鐘各抽血一次以分析血中乳酸。所得資料以單因子共變數分析處理。結果發現:一、馬達驅動式動態恢復在恢復期第5、10分鐘時恢復心跳率顯著的高於靜態恢復。二、馬達驅動式動態恢復在恢復期第5、10和15分鐘時換氣量與耗氧量皆顯著的高於靜態恢復。三、激烈運動後以馬達驅動式恢復15分鐘，使血中乳酸濃度顯著低於靜態恢復。本研究結果顯示，激烈運動後抹馬達驅動式恢復，在短時間內仍維持生理尤進，較高的恢復期心跳率、換氣量和耗氧量，加速代謝產物乳酸的排除，縮短恢復的時間。

The purpose of this study was to investigate the effects of motor-driven exercise on recovery heart rate ，ventilation，oxygen uptake and blood lactate removal rate following a maximal exercise. Subjects were fifteen male students with average age ，height and weight of 22.0土2.5 yrs， 173.3士5.5 cm and 71.5土6.4 kg respectively. For attaining V02max， each subject performed a maximal cycling test with progressively increased workloads. Immediately following maximal exercise of 110% V02max on the bicycle ergometer， all subjects randomly performed one of the recoverytreatments， a static rest or a motor driven exercise. Expired air was determined by Sensormedics 2900 metabolic system. Bloodsamples for determination of lactate concentration were taken at rest ，5thand 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. Bloodlactate removal rate following 15 minutes of motor- driven exercise was significantly faster than that of static recovery. Theresults revealed that motor driven re∞Ivery 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.
