Supra-Versus Submaximal Cycle Ergometer Verification of VO<sub>2max</sub> in Males and Females
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<sub>2max</sub> test and 4 VP tests at 80, 90, 100, and 105...

Summary: | 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<sub>2max</sub> test and 4 VP tests at 80, 90, 100, and 105% of the maximum wattage achieved during the GXT. GXT and VP VO<sub>2max</sub> values showed a significant test x sex interaction (<i>p</i> = 0.02). The males elicited significantly higher VO<sub>2max</sub> values during the GXT, 80%, and 90% when compared to the 105%, (105 vs. GXT: <i>p</i> = 0.05; 105% vs. 80%: <i>p</i> < 0.01; 105% vs. 90%: <i>p</i> = 0.02). There were no significant differences in VO<sub>2max</sub> across the tests in the females (<i>p</i> > 0.05); 80% of the males achieved their highest VP VO<sub>2max</sub> 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<sub>2max</sub> during cycle ergometer testing. For females, a range of intensities (80-105%) produce similar VO<sub>2max</sub> values. However, the 80% VP yields an unnecessarily high time to exhaustion. |
