The purpose of this investigation was to assess the validity of a 500-yard shallow water run test to determine peak aerobic power (VO2peak) and to compare it with the commonly used 1.5-mile run test. Subjects included 15 men and 28 women who completed two trials each of a 500-yard shallow water run test and a 1.5-mile run and then completed a graded exercise test on a treadmill to determine VO2peak. Correlation coefficients with measured VO2peak were -0.89 and -0.80 for the 1.5-mile and 500-yard water runs, respectively. Multiple regression analyses revealed that prediction of VO2peak from 1.5-mile run time was significantly improved by including the 1.5-mile run peak HR (R2 = 0.82, SEE = 3.52 ml.kg-1.min-1). Similarly, for the 500-yard water run test, percent body fat and height were significant additional predictors of VO2peak (R2 = 0.86, SEE = 3.19 ml.kg-1.min-1). We conclude that the 500-yard shallow water run test, especially when used with the descriptive measures of percent body fat and height, can provide a reasonable estimate of an individuals' cardiorespiratory fitness classification. However, caution is advised when administering these tests in older populations or in those with multiple coronary risk factors.
本研究的目的是评估500码浅水跑测试用于确定最大有氧功率（VO2峰值）的有效性，并将其与常用的1.5英里跑测试进行比较。受试者包括15名男性和28名女性，他们分别完成了500码浅水跑测试和1.5英里跑的两次试验，然后在跑步机上完成了分级运动测试以确定VO2峰值。1.5英里跑和500码水跑与测量的VO2峰值的相关系数分别为-0.89和-0.80。多元回归分析显示，通过纳入1.5英里跑的峰值心率，从1.5英里跑时间预测VO2峰值有显著改善（R2 = 0.82，标准误 = 3.52毫升·千克-1·分钟-1）。同样，对于500码水跑测试，体脂百分比和身高是VO2峰值的显著额外预测因素（R2 = 0.86，标准误 = 3.19毫升·千克-1·分钟-1）。我们得出结论，500码浅水跑测试，特别是与体脂百分比和身高的描述性测量一起使用时，可以为个体的心肺适能分类提供合理估计。然而，在老年人群或有多种冠心病危险因素的人群中进行这些测试时，建议谨慎行事。
