摘　　要：目的:探讨跑节省化(RE)指标在表达耐力能力方面的重要程度与应用价值。方法:102名新兵进行18周5000米长跑训练,每周训练3次,以95%和105%个体通气无氧阈(VT)时的心率作为强度控制标准,以Polar心率表作为控制手段。测定其训练前后的VO2max、VT和RE及其相关指标,并运用主成分分析方法对表达有氧能力初始水平和训练效果的不同指标进行重要程度的分析。结果:18周耐力训练使VO2max增加了1.56%,VT-VO2提高了2.59%,而RE各值均显著下降(范围为7.68%～9.43%,P<0.01)。在表达耐力初始水平方面,RE各指标的贡献率较大;在表达耐力训练效果方面,VO2max与RE各指标的贡献率和因子载荷较大。结论:RE在评价普通人群(即训练初期)的耐力及其耐力训练效果方面优于VO2max和VT指标。Objective The aim of this study was to evaluate the importance and the application value of running economy （RE） in expressing the ability of endurance. Methods One hundred and two soldiers underwent an 18-week endurance training （5000m running）, three times a week. Training intensity was set at 95 % to 105 % of individual VT. VO2 max, VT, RE and their relevant variables were measured before and after 18-week endurance training. Main composition analysis was employed to evaluate the importance of the parameters in the expression of the initial level of aerobic endurance and the training effect. Results After 18-week endurance training, VO2max and VT-VO2 increased 1.56% and 2.59%, respectively; RE decreased 7.68%-9.43% （P〈0.01）. The contribution rate of RE was in the relative important position for expressing of the initial level of aerobic endurance, while the VO2 max and the contribution rate of RE and load of factors were in the relative important position for expressing the effect of endurance training. Conclusion RE was superior to VO2 max and VT for evaluating the endurance of general population （in initial period of training） and the effect of their endurance training.
