| 摘 要： | 目的: 观察健康志愿者不同功率递增速率完成症状限制性极限心肺运动试验（CPET）对CPET峰值运动相关核心指标的影响,及运动中呼吸交换率（RER）的变化。以探讨不同功率递增速率对CPET峰值运动相关指标的影响。方法: 选择12名健康志愿者在一周内不同工作天随机完成中等适度程度（30 W/min)及比较低（10 W/min）和比较高（60 W/min）3种不同功率递增速率CPET。按标准方法比较CPET数据主要峰值运动核心指标：峰值运动时的摄氧量、二氧化碳排出量、负荷功率、呼吸频率、潮气量、分钟通气量、心率、血压和氧脉搏,运动持续时间和CPET各时段的RER。对三组不同功率递增速率下各个指标的差异进行组间两两比较。结果: 与中等适度功率递增速率组比较,比较低和比较高功率递增速率组的峰值功率分别显著地降低和升高（（162.04±41.59）W/min vs （132.92±34.55） W/min vs （197.42±46.14） W/min, P<0.01）;运动时间显著延长和缩短（（5.69±1.33） min vs （13.49±3.43） min vs （3.56±0.76） min,P<0.01）;峰值RER（1.27±0.07 vs 1.18±0.06 vs 1.33±0.08,P<0.01~P<0.05）与恢复期RER最大值（1.72±0.16 vs 1.61±0.11 vs 1.81±0.14,P<0.01~P<0.05）均显著降低和升高。结论: 不同功率递增速率CPET显著改变峰值运动时的功率、运动持续时间、峰值RER和恢复期最大RER。CPET规范化操作要选择个体化适合受试者的中等适度功率递增速率,而且也不能以某一固定的RER值作为保证安全、受试者达到极限运动和提前终止运动的依据。

| Abstract: | Objective: To observe the effect of healthy volunteers different work rate increasing rate cardiopulmonary exercise test (CPET) on the peak exercise core indicators and the changes of respiratory exchange rate (RER) during exercise, to explore the effect of different work rate increasing rate on CPET peak exercise related indicators. Methods: Twelve healthy volunteers were randomly assigned to a moderate (30 W/min), a relatively low (10 W/min) and relatively high (60 W/min) three different work rate increasing rate CPET on different working days in a week. The main peak exercise core indicators of CPET data: VO2, VCO2, work rate (WR), breathe frequency(Bf), tidal volume (VT), ventilation (VE), heart rate (HR), blood pressure (BP), Oxygen pulse(O2P), exercise time and RER for each period of CPET were analyzed using standard methods. The ANOVA test and paired two-two comparison was performed on the difference of each index in the three groups of different work rate increasing rate. Results: Compared with the moderate work rate group, the peak work rate of the lower and higher work rate groups were relatively lower and higher, respectively ((162.04±41.59) W/min vs (132.92±34.55) W/min vs (197.42±46.14) W/min, P<0.01); exercise time was significantly prolonged and shortened ((5.69 ± 1.33) min vs (13.49 ± 3.43) min vs (3.56 ± 0.76) min, P<0.01); peak RER (1.27 ± 0.07 vs 1.18 ± 0.06 vs 1.33 ± 0.08, P<0.01~P<0.05) and the recovery RER maximum (1.72±0.16 vs 1.61±0.11 vs 1.81±0.14, P<0.01~P<0.05) were significantly decreased and increased. Conclusion: Different work rate increasing rate of CPET significantly change the Peak Work Rate, exercise time, Peak RER, and maximum RER during recovery. The CPET operator should choose an individualized work rate increasing rate that is appropriate for the subject, and also does not use a fixed RER value as a basis for ensuring safety, the subject's extreme exercise, and early termination of exercise. |
