The purpose of this study was to assess the validity of v(amax) as an indicator of middle-distance running performance in sub-elite young runners, v(amax) being defined as the quotient maximal oxygen uptake (VO2max) divided by the net energy cost of running (Cr) on a treadmill at a submaximal running velocity (280 m x min[-1]). The VO2max, ventilatory threshold, v(amax), and Cr were assessed in 39 young male sub-elite runners having only small variations in performance level. The relationship between each variable and running performance (at 1500 m, 3000 m, and 5000 m) was evaluated. A trend toward a negative correlation existed between Cr and performance although this was not significant. The VO2max and v(amax) were significantly related to performance. The v(amax) accounted for around 50% of the variability in performance whereas other physiological variables selected in this study were responsible, at best, for approximately 39%. The results presented in this study suggested that v(amax) was a useful indicator of middle-distance running performance in sub-elite young runners with similar performance levels as well as in top elite athletes.
本研究的目的是评估最大速度（v(amax)）作为次精英年轻跑步运动员中长跑成绩指标的有效性，v(amax)定义为在次最大跑步速度（280米/分钟）下跑步机上最大摄氧量（VO2max）除以跑步净能量消耗（Cr）的商。对39名成绩水平差异较小的年轻男性次精英跑步运动员进行了VO2max、通气阈、v(amax)和Cr的评估。评估了每个变量与跑步成绩（1500米、3000米和5000米）之间的关系。Cr与成绩之间存在负相关趋势，尽管不显著。VO2max和v(amax)与成绩显著相关。v(amax)约占成绩变异性的50%，而本研究中选择的其他生理变量最多约占39%。本研究结果表明，v(amax)是次精英年轻跑步运动员以及顶级精英运动员中长跑成绩的有用指标，这些运动员的成绩水平相似。
