摘　　要：通过观察与分析耐力训练对跑节省化（RE）和最大摄氧量（WO2max）的影响，探讨RE指标在表达耐力训练效果方面的应用价值。对42名士兵进行10周5km长跑训练，测定训练前后的WO2max和RE，并运用主成分分析方法对耐力训练效果的指标进行相对重要程度的分析。结果显示：5km长跑训练使普通人的R—WO2max增加了4．0％（P〈0．01），RE各指标有非常显著的下降（3．0％～9．0％，P〈0．05），提示RE在评价耐力训练效果方面较之WO2max有更明显的敏感性；在表达耐力训练效果方面，RE的贡献率和因子载荷均高于WO2max。研究结果表明，RE在评价普通人群耐力训练效果方面优于WO2max指标。By observing and analyzing the influence of endurance training on running economy （RE） and maximal oxygen uptake, this research aims to discuss value of RE index in expressing the effect of endurance training. 42 soldiers were given a 10- week endurance training of 5 kilometer nmning and their indexes of WO2max and RE were measured before and after each training. To evaluate the importance of the indexes in endurance training effect by the method of main composition analysis, the 5 kilometer long distance nmning training led to increase of 4% in R - VO2max, and the noticeable decrease in RE（3.0%-9.0%, P 〈 0.05）.The result indicates that RE, compared to WO2max , has more noticeable sensitivity in evaluating the effect of endurance training, that the contribution rate of RE index is in the relative important position in expressing the effect of endurance training, whereas the WO2max, the contribution rate of RE plays most important role in expressing the effect of endurance training. The index of RE is superior to that of WO2max in evaluating the effect of t average people＇s endurance training.
