The purpose of the investigation was to explore the validity of using timed distance runs as predictorr of cardiorespiratory fitness in young untrained children. Maximal oxygen consumption and performance in runs of 549, 1207, and 1609 meters (600 yards, 3/4 mile, and 1 mile) were compared in 38 children eight years of age. Males were found to exceed females on Vo2max and possessed significantly faster times in the 1207 and 1609 meter runs. The females exhibited greater six-site skinfold totals. The 1609 meter run proved to be the best predictor of Vo2max (ml/kg) in males. However, none of the three distances was acceptable for females.
该调查的目的是探讨在未经训练的幼儿中，使用定时长跑作为心肺适能预测指标的有效性。对38名8岁儿童的最大耗氧量以及549米（600码）、1207米（3/4英里）和1609米（1英里）跑步成绩进行了比较。结果发现，男性的最大耗氧量超过女性，且在1207米和1609米跑步中用时显著更快。女性的六个部位皮褶厚度总和更大。1609米跑被证明是男性最大耗氧量（毫升/千克）的最佳预测指标。然而，这三个距离对女性来说都不可接受。
