The purpose of the investigation was to explore the validity of using timed distance runs as predictors of cardiorespiratory fitness in first, second and third grade children. Maximal oxygen uptake (Vo2 max), determined via the open-circut method during treadmill running, and performance on runs of 800, 1200 and 1600 meters were compared for 83 children. Males were found to exceed females on Vo2 max and possessed significantly faster times on all the distances run. The 1600-meter run proved to be the best predictor of Vo2 max (ml/kg) in both sexes. Test-retest reliability of the 1600-meter run was checked with 120 students and found to range from +.824 for first grade females to + .918 for third grade males. Normative values for first, second, and third grade students were calculated from data collected on 1440 elementary students. All subjects studied had previously received instruction and practice on the phenomenon of paced distance running.
该调查的目的是探讨将定时长跑作为一、二、三年级儿童心肺适能预测指标的有效性。对83名儿童进行了比较，通过跑步机跑步时的开路法测定其最大摄氧量（Vo2 max），并比较他们在800米、1200米和1600米跑步中的表现。结果发现，男性的Vo2 max超过女性，且在所有跑步距离上的用时都明显更快。1600米跑被证明是男女Vo2 max（毫升/千克）的最佳预测指标。对120名学生进行了1600米跑的重测信度检查，发现信度范围从一年级女生的 +.824到三年级男生的 +.918。根据从1440名小学生收集的数据计算出一、二、三年级学生的标准值。所有参与研究的受试者此前都接受过关于定速长跑现象的指导和练习。
