To develop a track version of the maximal anaerobic running test, 10 sprint runners and 12 distance runners performed the test on a treadmill and on a track. The treadmill test consisted of incremental 20-s runs with a 100-s recovery between the runs. On the track, 20-s runs were replaced by 150-m runs. To determine the blood lactate versus running velocity curve, fingertip blood samples were taken for analysis of blood lactate concentration at rest and after each run. For both the treadmill and track protocols, maximal running velocity (v max), the velocities associated with blood lactate concentrations of 10 mmol x l-1 (v10 mM) and 5 mmol x l(-1) (v5 mM), and the peak blood lactate concentration were determined. The results of both protocols were compared with the seasonal best 400-m runs for the sprint runners and seasonal best 1000-m time-trials for the distance runners. Maximal running velocity was significantly higher on the track (7.57 +/- 0.79 m x s(-1)) than on the treadmill (7.13 +/- 0.75 m x s(-1)), and sprint runners had significantly higher vmax, v10 mM, and peak blood lactate concentration than distance runners (P < 0.05). The Pearson product--moment correlation coefficients between the variables for the track and treadmill protocols were 0.96 (v max), 0.82 (v10 mM), 0.70 (v5 mM), and 0.78 (peak blood lactate concentration) (P < 0.05). In sprint runners, the velocity of the seasonal best 400-m run correlated positively with vmax in the treadmill (r = 0.90, P < 0.001) and track protocols (r = 0.92, P < 0.001). In distance runners, a positive correlation was observed between the velocity of the 1000-m time-trial and vmax in the treadmill (r = 0.70, P < 0.01) and track protocols (r = 0.63, P < 0.05). It is apparent that the results from the track protocol are related to, and in agreement with, the results of the treadmill protocol. In conclusion, the track version of the maximal anaerobic running test is a valid means of measuring different determinants of sprint running performance.
为开发最大无氧跑测试的跑道版本，10名短跑运动员和12名长跑运动员在跑步机和跑道上进行了该测试。跑步机测试包括每次持续20秒的递增跑，每次跑之间有100秒的恢复时间。在跑道上，20秒的跑被150米的跑所取代。为确定血乳酸与跑步速度曲线，在休息时以及每次跑步后采集指尖血样以分析血乳酸浓度。对于跑步机和跑道测试方案，均测定了最大跑步速度（v max）、与血乳酸浓度为10 mmol·L-1（v10 mM）和5 mmol·L-1（v5 mM）相关的速度以及血乳酸峰值浓度。将两种测试方案的结果与短跑运动员的赛季最佳400米跑成绩以及长跑运动员的赛季最佳1000米计时赛成绩进行比较。跑道上的最大跑步速度（7.57±0.79 m·s-1）显著高于跑步机上的（7.13±0.75 m·s-1），并且短跑运动员的v max、v10 mM和血乳酸峰值浓度显著高于长跑运动员（P<0.05）。跑道和跑步机测试方案各变量之间的Pearson积矩相关系数分别为0.96（v max）、0.82（v10 mM）、0.70（v5 mM）和0.78（血乳酸峰值浓度）（P<0.05）。在短跑运动员中，赛季最佳400米跑的速度与跑步机测试方案中的v max呈正相关（r = 0.90，P<0.001），与跑道测试方案中的v max也呈正相关（r = 0.92，P<0.001）。在长跑运动员中，1000米计时赛的速度与跑步机测试方案中的v max呈正相关（r = 0.70，P<0.01），与跑道测试方案中的v max也呈正相关（r = 0.63，P<0.05）。显然，跑道测试方案的结果与跑步机测试方案的结果相关且一致。总之，最大无氧跑测试的跑道版本是测量短跑成绩不同决定因素的有效方法。
