摘要/Abstract

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亚极限运动相关核心指标的影响。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12名志愿者CPET亚极限运动相关核心指标：无氧阈（AT）、单位功率摄氧量（ΔVO₂/ΔWR）、摄氧通气有效性峰值平台（OUEP）、二氧化碳通气当量平均90 s最低值（Lowest VE/ VCO₂）、二氧化碳通气当量斜率（VE/ VCO₂ Slope）及截距（intercept）和无氧阈时的摄氧通气效率值（VO₂/ VE@AT）和无氧阈时的二氧化碳通气当量值（VE/ VCO₂@AT）。对三组不同功率递增速率下各个指标的差异组间两两比较。结果: 中等适度功率递增速率组与比较低和比较高功率递增速率组相比摄氧通气有效性峰值平台（42.22±4.76 vs 39.54±3.30 vs 39.29±4.29）和二氧化碳通气当量平均90 s最小值（24.13±2.88 vs 25.60±2.08 vs 26.06±3.05）明显好,差异有统计学意义（P<0.05）;比较低、比较高功率递增速率组与中等适度功率递增速率组相比,单位功率摄氧量显著升高和降低（（8.45±0.66 vs 10.04±0.58 vs 7.16±0.60）ml/（min·kg））,差异有统计学意义（P<0.05）;无氧阈值没有发生明显改变（（0.87±0.19 vs 0.87±0.19 vs 0.89±0.19）L/min）,差异无统计学意义（P>0.05）;结论: 比较低、比较高功率递增速率可以明显改变摄氧通气有效性、二氧化碳排出通气有效性、单位功率摄氧量等CPET亚极限运动相关指标;选择比较低和比较高的功率递增速率和适度功率递增速率CPET相比明显降低了健康个体的摄氧通气有效性和二氧化碳排出通气有效性。CPET规范化操作要求选择适合受试者的功率递增速率,这样得到的CPET亚极限相关指标才最能反应受试者的真实功能状态。

Abstract: Objective: To observe the effect of healthy volunteers different work rate increasing rate cardiopulmonary exercise testing (CPET) on the sub-peak parameters . 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 core indicators related to CPET sub-peak exercise of 12 volunteers were compared according to standard Methods: anaerobic threshold (AT), oxygen uptake per unit power (ΔVO₂/ΔWR), oxygen uptake eficiency plateau,（OUEP), the lowest average of 90 s of carbon dioxide ventilation equivalent (Lowest VE/ VCO₂), the slope of carbon dioxide ventilation equivalent (VE/ VCO₂ Slope) and intercept and anaerobic threshold oxygen uptake ventilation efficiency value (VO₂/ VE@AT) and the anaerobic threshold carbon dioxide ventilation equivalent value (VE/ VCO₂@AT). Paired t test was performed on the difference of each parameter in the three groups of different work rate increasing rate. Results: Compared with the relatively low and relatively high work rate increasing rate group, the moderate work rate increasing rate group uptake eficiency plateau, (42.22±4.76 vs 39.54±3.30 vs 39.29±4.29) and the lowest average of 90 s of carbon dioxide ventilation equivalent (24.13±2.88 vs 25.60±2.08 vs 26.06±3.05) was significantly better, and the difference was statistically significant (P<0.05); Compared with the moderate work rate increasing rate group, the oxygen uptake per unit work rate of the relatively low and relatively high work rate increasing rate group increased and decreased significantly ((8.45±0.66 vs 10.04±0.58 vs 7.16±0.60) ml/(min·kg)), difference of which was statistically significant (P<0.05); the anaerobic threshold did not change significantly ((0.87±0.19 vs 0.87±0.19 vs 0.89±0.19) L/min), the difference was not statistically significant (P>0.05). Conclusion: Relatively low and relatively high power increase rate can significantly change the CPET sub-peak sports related indicators such as the effectiveness of oxygen uptake ventilation, the effectiveness of carbon dioxide exhaust ventilation, and the oxygen uptake per unit work rate. Compared with the moderate work rate increasing rate CPET, the lower and higher work rate increasing rate significantly reduces the effectiveness of oxygen uptake ventilation and the effectiveness of carbon dioxide exhaust ventilation in healthy individuals. The standardized operation of CPET requires the selection of a work rate increasing rate suitable for the subject, so that the CPET sub-peak related indicators can best reflect the true functional state of the subject.
