摘　　要：通过观察与分析耐力训练对跑节省化(RE)和通气无氧阈(VT)的影响,探讨RE指标在表达耐力训练效果的应用价值。对42名士兵进行10周5km长跑训练,测定训练前后的VT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VT相对值增加了12%(P<0.01),RE各指标(绝对值、相对值和修正值)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VT有明显的敏感性;在表达耐力训练效果方面,RE的贡献率和因子载荷均高于VT。研究结果表明,RE在评价普通人群耐力训练效果方面优于VT指标。By observing and analyzing the influence of endurance training on running economy（RE） and anaerobic threshold,this paper 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 running and their indexes of VT and RE were measured before and after training.The main purpose was to evaluate the importance of the indexes in endurance training effect by the method of main composition analysis.The result showed that the 5 kilometer long distance running training led to increase of 12% in r-VT,and the noticeable decrease in the indexes of RE（3.0%～9.0%,P0.05）.It indicates that RE,compared to VT,has more noticeable sensitivity in evaluating the effect of endurance training.The contribution rate of RE played the most important role in expressing the effect of endurance training.The index of RE was superior to that of VT in evaluating the effect of the average peoples＇ endurance training.
