To assess the relative biological and technological variability of anaerobic testing, 27 male subjects performed either 30- or 60-s sprint bouts on a hydraulically braked Fitron ergometer or timed rides to exhaustion at 125% VO2max on an electrically braked Collins ergometer. Each subject performed four trials within a 4-week period, with blood drawn 10 min post-exercise for lactate determination. Total variability was estimated from the mean coefficient of variation (CV = SD/means X 100%) for each variable. There were no significant differences across the four trials of each test for any of the variables measured (mean power or ride time, peak torque, fatiguability, or blood lactate). There were also no significant differences in test variabilities. The mean CV of performance were 5.4%, 5.4%, and 5.3% for the 30-s Fitron, 60-s Fitron, and exhaustive tests, respectively. The magnitude of this variability is nearly identical to that reported for tests of aerobic fitness. Only 10%-30% of the variability was of technological origin. This variability must be considered in the interpretation of experiments utilizing anaerobic performance tests.
为评估无氧测试的相对生物学和技术变异性，27名男性受试者在液压制动的Fitron测力计上进行了30秒或60秒的冲刺运动，或在电动制动的Collins测力计上以125%的最大摄氧量进行定时骑行直至力竭。每位受试者在4周内进行了4次试验，运动后10分钟采血测定乳酸。通过计算每个变量的平均变异系数（CV = SD/均值×100%）来估计总变异性。对于所测量的任何变量（平均功率或骑行时间、峰值扭矩、疲劳性或血乳酸），每个测试的4次试验之间均无显著差异。测试变异性也无显著差异。30秒Fitron测试、60秒Fitron测试和力竭测试的性能平均变异系数分别为5.4%、5.4%和5.3%。这种变异性的大小与有氧适能测试报告的几乎相同。只有10%-30%的变异性源于技术因素。在解释利用无氧性能测试的实验结果时，必须考虑这种变异性。
