The purpose of this study was to determine the value of the peak oxygen deficit (POD) as a predictor of sprint and middle-distance track performance. POD, peak blood lactate, VO2peak, lactate threshold, and running economy at 3.6 m.s-1 were measured during horizontal treadmill running in 22 male and 19 female competitive runners of different event specialties. Subjects also completed running performance trials at 100, 200, 400, 800, 1500, and 5000 m. Correlations of track performances with POD (ml.kg-1) (-0.66, -0.71, -0.71, -0.62, -0.52, and -0.40) were moderately strong at the sprint and middle distances, accounting for 44-50% of the performance variance at the three shortest distances. Correlations of track performances with peak blood lactate concentration were lower than with POD and accounted for approximately one-half as much of the performance variance (21-26%) at the three shortest distances. Multiple regression analyses indicated that the POD was the strongest metabolic predictor of 100-, 200- and 400-m performance, and that VO2peak was the strongest metabolic predictor of 800-, 1500-, and 5000-m performance. We conclude that the POD is a moderately strong predictor of sprint and middle-distance track performance.
本研究的目的是确定峰值氧亏（POD）作为短跑和中距离径赛成绩预测指标的价值。在水平跑步机上对22名男性和19名女性不同项目专长的竞技跑步者进行测试，测量其POD、血乳酸峰值、最大摄氧量（VO₂peak）、乳酸阈值以及3.6米/秒速度下的跑步经济性。受试者还完成了100米、200米、400米、800米、1500米和5000米的跑步成绩测试。在短跑和中距离项目中，径赛成绩与POD（毫升/千克）的相关性（-0.66、-0.71、-0.71、-0.62、-0.52和-0.40）较强，在三个最短距离项目中占成绩方差的44%-50%。径赛成绩与血乳酸峰值浓度的相关性低于与POD的相关性，在三个最短距离项目中占成绩方差的比例约为一半（21%-26%）。多元回归分析表明，POD是100米、200米和400米成绩最强的代谢预测指标，而VO₂peak是800米、1500米和5000米成绩最强的代谢预测指标。我们得出结论，POD是短跑和中距离径赛成绩的一个较强预测指标。
