Physiological measures of performance capacity have traditionally centered around the measurement of maximal oxygen uptake (VO2max). This study examined the relationship between maximal and submaximal laboratory measures of performance and running times within a group of trained middle distance runners. Analysis of the data obtained from 10 male and 2 female athletes identified the running velocity corresponding to the Ventilatory Threshold [(VT) (mean +/- SD = 15.3 +/- 2.36 km.h-1. treadmill speed)] as the major correlate with 3000 m (r = -0.984, n = 12) running performance. Treadmill speed corresponding with the heart rate deflection point [(Vd) (mean +/- SD = 16.75 +/- 2.38)] and the VO2max (mean +/- SD = 55 +/- 6 ml.kg-1.min-1) was also highly correlated (r = 0.94 and r = 0.82 respectively, n = 12) with 3000 m running performance. The running velocity corresponding with VT alone explained 96.3% of the variance in 3000 m performance time. The addition of VO2max and Vd using multiple regression analysis did not further improve significantly the predictive value of the physiological measures. The results of this study support the laboratory estimation of physiological measures such as Vd and VT in the assessment of middle distance running performance.
传统上，运动能力的生理测量主要围绕最大摄氧量（VO2max）的测量。本研究调查了一组训练有素的中长跑运动员的最大和次最大实验室运动测量值与跑步时间之间的关系。对10名男性和2名女性运动员的数据进行分析后发现，对应于通气阈值的跑步速度[（VT）（平均值±标准差=15.3±2.36千米/小时，跑步机速度）]与3000米跑成绩（r=-0.984，n=12）高度相关。对应于心率拐点的跑步机速度[（Vd）（平均值±标准差=16.75±2.38）]以及最大摄氧量（平均值±标准差=55±6毫升/千克·分钟）也与3000米跑成绩高度相关（分别为r=0.94和r=0.82，n=12）。仅对应于VT的跑步速度就解释了3000米成绩时间96.3%的方差。使用多元回归分析加入最大摄氧量和心率拐点并没有显著提高生理测量值的预测价值。本研究结果支持在评估中长跑成绩时对诸如心率拐点和通气阈值等生理测量值进行实验室估计。
