The primary purpose of this study was to develop a submaximal field test for the estimation of maximal oxygen uptake (VO2max) using a 1-mile track jog. A second purpose was to determine the accuracy of the 1.5-mile run in estimating VO2max for both male and female subjects. VO2max was measured in 149 relatively fit college students (males = 88, females = 61) 18-29 yr using a treadmill protocol (mean +/- SD; VO2max = 47.7 +/- 6.3 ml.kg-1 x min-1). Multiple regression analysis (N = 54) to estimate VO2max from the submaximal, steady-state 1-mile track jog yielded the following validation (V) model (r(adi) = 0.87, SEE = 3.0 ml.kg-1 x min-1): VO2max = 100.5 + 8.344* GENDER (0 = female; 1 = male) - 0.1636* BODY MASS (kg) - 1.438* JOG TIME (min.mile-1) - 0.1928* HEART RATE (bpm). To help ensure that a submaximal level of exertion was realized for the 1-mile track jog, elapsed jog time was restricted to > or = 8.0 min for males and > or = 9.0 min for females and exercise HR to < or = 180 bpm. Cross-validation (CV) of the 1-mile track jog comparing observed and estimated VO2max (N = 52) resulted in radj = 0.84, SEE = 3.1 ml.kg-1 x min-1. Multiple regression analysis (N = 50) to estimate VO2max from the 1.5-mile run (V:N = 49, radj = 0.90, SEE = 2.8 ml.kg-1 x min-1; CV: N = 47, radj = 0.82, SEE = 3.9 ml.kg-1 x min-1), used elapsed run time, body mass, and gender as independent variables.(ABSTRACT TRUNCATED AT 250 WORDS)
本研究的主要目的是开发一种次极量现场测试方法，通过1英里跑道慢跑估计最大摄氧量（VO2max）。第二个目的是确定1.5英里跑在估计男性和女性受试者VO2max方面的准确性。使用跑步机方案对149名年龄在18 - 29岁、身体相对健康的大学生（男性88名，女性61名）进行VO2max测量（均值±标准差；VO2max = 47.7±6.3 ml·kg⁻¹·min⁻¹）。通过次极量、稳态1英里跑道慢跑估计VO2max的多元回归分析（N = 54）得出以下验证（V）模型（调整后r = 0.87，标准误 = 3.0 ml·kg⁻¹·min⁻¹）：VO2max = 100.5 + 8.344×性别（0 = 女性；1 = 男性） - 0.1636×体重（kg） - 1.438×慢跑时间（min·mile⁻¹） - 0.1928×心率（bpm）。为确保1英里跑道慢跑达到次极量运动水平，男性慢跑时间限制为≥8.0分钟，女性为≥9.0分钟，运动心率限制为≤180 bpm。1英里跑道慢跑的交叉验证（CV）（比较观察到的和估计的VO2max，N = 52）得出调整后r = 0.84，标准误 = 3.1 ml·kg⁻¹·min⁻¹。通过1.5英里跑估计VO2max的多元回归分析（N = 50）（V：N = 49，调整后r = 0.90，标准误 = 2.8 ml·kg⁻¹·min⁻¹；CV：N = 47，调整后r = 0.82，标准误 = 3.9 ml·kg⁻¹·min⁻¹），使用跑步时间、体重和性别作为自变量。（摘要截断于250字）
