目的：研究两种典型运动模型下耗氧动力学特征并分析其特征参数之间关系。方法：34名受试者分别进行一次斜坡式递增负荷力竭测试和3次中等强度下的动力学重复测试，用线性和非线性函数模型拟合耗氧量变化的特征参数。结果：斜坡式递增负荷模式中，耗氧量（VO2）和功率（Waat ）的一次线性函数拟合优度 R2为0．932±0．151（ P＜0．01）；而通气量（VE）和VO2的非线性对数函数拟合优度 R2为0．977±0．012（P＜0．01）；中等强度重复运动中，其痹VO2随时间变化的指数函数拟合优度 R2为0．96±0．02（ P＜0．01）；耗氧动力学参数△效率（Delta Efficiency ）Aslop与最大耗氧量（VO2 max ）绝对值、相对值及通气无氧阈（VT ）相关系数介于0．600～0．757（ P＜0．01）；耗氧效率坡度（Oxygen Uptake Efficiency Slop ，OUES ）AOUES与VO2 max的相关系数为0．756、0．600（ P＜0．01）；而中等强度下的氧动力学参数τ（Tau ）与 Aslop 、AOUES无显著性关系（ P＞0．05）。结论：斜坡式递增负荷测试中，痹VO2和Waat等呈现不同的函数特征；所衍生的特征参数△效率、OUES与VO2 max 及VT 存在不同程度的中高度相关，在耐力评定中具有一定参考价值；而中等强度下的氧动力学参数和上述指标无明显关系。

Objective :The characters and relationship of two typical exercise test models were re‐searched in the study .Method :34 subject were recruited to finish two exercise test :one was incremental ramp exhaustive test ,other was moderate‐ intensity constant test .The data about oxygen uptake was fitted by linear and nonlinear function models .Results :The goodness R2 of fitting oxygen consumption (VO2 ) and power (Waat ) was 0 .932 ± 0 .151 ( P< 0 .01 ) by a linear function in the ramp test .The goodness R2 of fitting ventilation (VE ) with VO2 was 0 .977 ± 0 .012 ( P<0 .01 ) by nonlinear logarithmic function in the ramp test .In the moderate repetitived test ,goodness R2 of fit is 0 .96 ± 0 .02 ( P< 0 .01 ) ,where VO2 changed with time as exponential function .There were significant correlation ( P< 0 .01 ) between Delta Efficien‐cy ,maximal oxygen uptake and VT ,whose correlation coefficient was from 0 .600 to 0 .757 ;There was no significant correlation between OUES ,Delta Efficiency and τ .Conclusion :In ramp test ,VO2 was changed with Waat by typical linear features ,while there was typical loga‐rithmic function features between VE and VO2 ,there are significant differences before and af‐ter VT in the △ efficiency ;and in moderate‐intensity constant test ,VO2 showed a single ex‐ponential increase with time in response to the steady‐state mode ,there were different levels correlation between △ efficiency ,OUES and VT ,VO2 max .
