This study was designed to determine the optimal intensity for verification phase testing (VP) in healthy, young adults. Thirty one young, active participants (16 females) completed a cycle ergometer graded exercise test (GXT) VO_2max test and 4 VP tests at 80, 90, 100, and 105% of the maximum wattage achieved during the GXT. GXT and VP VO_2max values showed a significant test x sex interaction (p = 0.02). The males elicited significantly higher VO_2max values during the GXT, 80%, and 90% when compared to the 105%, (105 vs. GXT: p = 0.05; 105% vs. 80%: p < 0.01; 105% vs. 90%: p = 0.02). There were no significant differences in VO_2max across the tests in the females (p > 0.05); 80% of the males achieved their highest VP VO_2max during a submaximal VP test compared to only 37.5% of the females. A secondary study conducted showed excellent reliability (ICCs > 0.90) and low variation (CVs < 3%) for the 90% VP. Our findings show that a submaximal verification phase intensity is ideal for young healthy males to elicit the highest VO_2max during cycle ergometer testing. For females, a range of intensities (80–105%) produce similar VO_2max values. However, the 80% VP yields an unnecessarily high time to exhaustion.

超对亚最大循环测功机验证男女最大摄氧量

本研究旨在确定健康的年轻人中验证阶段测试（VP）的最佳强度。31名活跃的年轻参与者（16名女性）在GXT期间达到的最大功率的80％，90％，100％和105％处完成了自行车测功计分级运动测试（GXT）VO _2max测试和4 VP测试。GXT和VP VO _2max值显示出显着的x性别相互作用测试（p = 0.02）。与105％相比，男性在GXT期间诱发的VO _2max值显着更高，分别为80％和90％（105 vs. GXT：p = 0.05； 105％vs. 80％：p <0.01； 105％vs. 90％：p = 0.02）。VO _2max无明显差异女性的所有测试（p > 0.05）；在次最大VP测试中，有80％的男性达到了最高的VP VO _2max，而女性中只有37.5％。进行的二次研究显示，对于90％的VP，其可靠性极佳（ICC> 0.90），变异性低（CV <3％）。我们的发现表明，次最大验证阶段强度非常适合年轻健康的男性在循环测功机测试期间引发最高VO _2max。对于女性，一系列强度（80–105％）会产生相似的VO _2max值。但是，80％VP会产生不必要的疲劳时间。
