The specificity of three maximal cycling sprint tests as a measure of anaerobic lactacid capacity was determined in nine highly trained male cyclists when they performed 10-, 30-, 40-, and 60-s tests on a modified Repco wind-braked cycle ergometer. Peak power (PP), percent power loss (% PO), total work done (TW), and peak blood lactate (PHLa) were determined for each test. The cyclists also performed a 1000-m time trial under competition conditions during which 200-m split times, total time (TT), and peak post-competition blood lactate (TTPHLa) were recorded. While there was no statistically significant difference between the peak blood lactate of the 30-, 40-, and 60-s tests, peak blood lactate achieved after the 1000-m time trial was significantly greater than those after the cycle ergometer tests. Although there were high intercorrelations (0.88-0.99) between the anaerobic power and capacity indices of the laboratory tests, only the PP and TW achieved during the 60-s test correlated significantly (P less than 0.05) with TT. The data suggest that when assessing the anaerobic power and capacity of elite 1000-m time trial cyclists, a cycle ergometer test duration of at least 60 s should be employed.
在9名训练有素的男性自行车运动员于改良的Repco风阻自行车测力计上进行10秒、30秒、40秒和60秒测试时，确定了三种最大骑行冲刺测试作为无氧乳酸能力测量方法的特异性。测定了每次测试的峰值功率（PP）、功率损失百分比（%PO）、总功（TW）和峰值血乳酸（PHLa）。自行车运动员还在比赛条件下进行了1000米计时赛，记录了200米分段时间、总时间（TT）和赛后峰值血乳酸（TTPHLa）。虽然30秒、40秒和60秒测试的峰值血乳酸之间没有统计学上的显著差异，但1000米计时赛后达到的峰值血乳酸明显高于自行车测力计测试后的峰值血乳酸。尽管实验室测试的无氧功率和能力指标之间存在高度相关性（0.88 - 0.99），但只有60秒测试期间达到的PP和TW与TT有显著相关性（P小于0.05）。数据表明，在评估精英1000米计时赛自行车运动员的无氧功率和能力时，应采用至少60秒的自行车测力计测试持续时间。
