摘　　要：目的:比较2类递增负荷力竭测试模式中共计3类12种数据处理方法对峰值摄氧量(VO_(2peak))的影响。方法:20名体力活动活跃的、身高为(178.2±7.0)cm、年龄为(21.4±1.4)岁的男性受试者分别进行3次不同负荷模式的力竭测试。3种负荷模式分别为连续分级递增负荷模式(graded exercise text,GXT)、连续斜坡式递增负荷模式(Ramp)和105%Wmax大负荷持续运动(105%CT)。结果:GXT和Ramp这2个递增负荷力竭测试之间虽然Wmax、运动时长(T)、血乳酸(La)、呼吸交换率(RER)均存在显著差异(P<0.05或P<0.01),但同一种数据处理方法所取得的VO_(2peak)差异不显著(P>0.05);GXT和Ramp这2个递增负荷模式对VO_(2peak)取值影响不显著(F=0.186,P=0.669),但数据处理方法对其影响显著(F=38.06,P<0.00);同一类数据处理间所取得的VO_(2peak)仅有7 M(7点移动平滑法)和9 M(9点移动平滑法)这2个方法无显著差异(P>0.05)。4种时间间隔平均法所取得的VO_(2peak)之间高度相关(r>0.9,P<0.01),差异显著(P<0.01)。结论:同一类功率仪、同一数据处理方法对VO_(2peak)的判定不受力竭测试中负荷模式的影响;而不同数据处理模式对VO_(2peak)判断既受到负荷模式的影响,也受到数据处理本身的影响。Purpose： The purpose of this study was to compare two types of incremental exercise testes and 12 data processing methods（ three types） on peak oxygen uptake（ VO2peak）. Methods： Twenty male 21. 4 ± 1. 4 years old people with 178. 2 ± 7. 0 cm height and good physical activity level were recruited,and finished three exhausted exercise tests including GXT,Ramp and constant exercise test（ 105% CT）. Results： There were differences of Wmax,the movement time（ T）,blood lactate（ La）,respiratory exchange rate（ RER） between GXT and Ramp（ Ps 〈0. 05）,but there was no difference of VO2peakbetween two tests when using the same data processing method（ P〉 0. 05）. GXT and Ramp didn＇t affect VO2peaksignificantly（ F = 0. 186,P = 0. 669）,but data processing methods influenced it（ F = 38. 06,P〈 0. 00）. The VO2peakwas different by using the same type of data processing methods except 7M and 9M（ P〉 0. 05）. The four values of VO2peakevaluated by time-interval averaging method showed high correlation（ r〉 0. 9,P〈 0. 01）. Conclusion： The VO2peakevaluated by the same data processing method and the same kind of power meter is not affected by load model of exhausted exercise test; VO2peakobtained by different data processing methods is influenced by load model and the data processing.
