The objective of this study was to compare the time to exhaustion (Tlim) at maximal aerobic speed (v.VO2max) in middle- and long-distance runners. Five middle-distance (MDR) and 5 long-distance (LDR) male runners, ages 28 +/- 7 years, were tested running on a treadmill, with the Université de Montréal Track Test (UMTT), on maximal velocity and on time-to-exhaustion track tests. During the laboratory test, cardiorespiratory variables (e.g., HR, .VO2max, .VCO2, .VE) were assessed. Second, running velocity at .VO2max (v.VO2max) during the UMTT was determined and HR values were recorded; also, maximal velocity on a 30-m sprint (V30) and maximal heart rate (HR max) and time to exhaustion were determined on the track. No significant difference was observed between groups during the multistage treadmill test. Significant differences were found between groups for V30 and Tlim, with MDR showing a 23% longer running time than LDR. The results of the present study demonstrated that the training profile of middle-distance and long-distance runners plays a significant role in Tlim performance when v.VO2max is obtained during a test with short-duration stages.
本研究的目的是比较中长跑运动员在最大有氧速度（v.VO2max）下的力竭时间（Tlim）。选取了5名年龄在28±7岁的男性中长跑运动员（MDR）和5名男性长跑运动员（LDR），在跑步机上进行测试，采用蒙特利尔大学跑道测试（UMTT），进行最大速度和力竭时间跑道测试。在实验室测试期间，评估心肺变量（如心率、VO2max、VCO2、VE）。其次，确定UMTT期间VO2max时的跑步速度（v.VO2max）并记录心率值；此外，在跑道上测定30米冲刺的最大速度（V30）、最大心率（HR max）和力竭时间。在多级跑步机测试中，两组之间未观察到显著差异。在V30和Tlim方面，两组之间存在显著差异，中长跑运动员的跑步时间比长跑运动员长23%。本研究结果表明，当中长跑运动员在短时间阶段测试中达到v.VO2max时，其训练模式在Tlim表现中起着重要作用。
