The 3,000 m run is a frequently used field test for evaluating aerobic fitness. The test has previously been validated using smaller sample sizes and with focus restricted to the correlation between run performance and maximal oxygen uptake (V̇O). The aim of the present study was to generate equations for converting 3,000 m performance into predicted V̇O , and present corresponding validity statistics. In total 259 (30 female) military cadets and recruits (18-39 years) participated in the study. The subjects carried out a 3,000 m run and a direct treadmill V̇O test. The Pearson between V̇O and average 3,000 m run speed were 0.74 and 0.79 in men and women, respectively. Two V̇O prediction equations were generated: (1) Men: Ŷ = 17.5 + 2.57X and (2) Women: Ŷ = 14.6 + 2.48X (X = 3,000 m average run speed in km·h). The equations produced a standard error of estimate of 3.3 and 2.6 mL·kg·min, and limits of agreement of 6.4 and 5.0 mL·kg·min in men and women, respectively. The validity of the 3,000 m test is comparable to other indirect maximal running tests and is a time-effective alternative aerobic fitness test in healthy and motivated subjects.
3000 米跑是评估有氧适能的常用现场测试。此前，该测试已经过较小样本量的验证，并且重点仅限于跑步表现与最大摄氧量（V̇O）之间的相关性。本研究的目的是生成将 3000 米表现转换为预测 V̇O的方程，并提出相应的有效性统计数据。共有 259 名（30 名女性）军事学员和新兵（18-39 岁）参加了这项研究。受试者进行了 3000 米跑和直接跑步机 V̇O 测试。男性和女性的 V̇O 与平均 3000 米跑速度之间的 Pearson 相关系数分别为 0.74 和 0.79。生成了两个 V̇O 预测方程：（1）男性：Ŷ=17.5+2.57X；（2）女性：Ŷ=14.6+2.48X（X=3000 米平均跑速，km·h）。该方程在男性和女性中的估计标准误差分别为 3.3 和 2.6 mL·kg·min，一致性界限分别为 6.4 和 5.0 mL·kg·min。3000 米测试的有效性与其他间接最大跑步测试相当，是健康且积极主动的受试者进行有氧适能测试的有效替代方法。
