The purpose of the present investigation was to examine the concurrent and construct validity of the three-mile (4.83 km) run as a field test of aerobic capacity. Subjects included 109 college-aged males whose three-mile run time (M = 1310.31 +/- 184.48 s) was measured. Fifty of the subjects were given a maximal treadmill stress test, and their peak oxygen consumption (VO2peak) (M = 54.23 +/- 7.08 ml.kg-1.min-1) was measured. The three-mile run was conducted on an outdoor 0.25 mile (0.425 km) track, and split times were recorded each 110 yds (100.32 m) for the first and last laps and total time was recorded for laps 2 through 11. The correlation coefficient between the run time and VO2peak was -.58, indicating only moderate concurrent validity for the run as a field test for aerobic capacity. A factor analysis conducted on the split time data revealed a three-factor structure of a stable pace phase, an initial sprint, and a final sprint with the stable pace factor accounting for most of the common factor variance (69%). The three-mile run time was used to discriminate successfully between two known groups of subjects in aerobic capacity. These data provide a degree of support for the construct validity of the three-mile run as a field test of aerobic capacity.
本研究的目的是检验三英里(4.83千米)跑作为有氧能力现场测试的同时效度和结构效度。研究对象包括109名大学年龄段的男性,测量了他们的三英里跑时间(M = 1310.31 +/- 184.48秒)。其中50名受试者进行了最大运动强度的跑步机压力测试,并测量了他们的最大摄氧量(VO2peak)(M = 54.23 +/- 7.08毫升·千克-1·分钟-1)。三英里跑在一条0.25英里(0.425千米)的室外跑道上进行,记录了第一圈和最后一圈每110码(100.32米)的分段时间以及第2圈到第11圈的总时间。跑时间与VO2peak之间的相关系数为-.58,表明该跑作为有氧能力现场测试的同时效度仅为中等。对分段时间数据进行的因素分析揭示了一个三因素结构,即稳定配速阶段、初始冲刺阶段和最终冲刺阶段,其中稳定配速因素占共同因素方差的大部分(69%)。三英里跑时间成功地区分了两组已知有氧能力的受试者。这些数据为三英里跑作为有氧能力现场测试的结构效度提供了一定程度的支持。
