Abstract

The purpose of this study was to verify whether the exercise modality (i.e., running and cycling) alters the magnitude of ``anaerobic{''} capacity estimated by a single supramaximal effort (AC({[}La]+EPOCfast)). Fourteen healthy men (age: 26 +/- 9 years) underwent a maximum incremental test and a supramaximal effort to exhaustion at 115% of the intensity associated with maximal oxygen uptake to determine the AC({[}La]+EPOCfast) (i.e., the sum of both oxygen equivalents from the glycolytic and phosphagen pathways), performed on both a treadmill and cycle ergometer. The maximal oxygen uptake during running was higher (p = 0.001; large effect size) vs. cycling (48.9 +/- 3.9mL.kg(-1).min(-1) vs. 44.8 +/- 5.5mL.kg(-1).min(-1) respectively). Contrarily, the oxygen equivalent from the glycolytic metabolism was not different between exercise modalities (p = 0.133; small effect size; running = 2.35 +/- 0.48 L and cycling = 2.18 +/- 0.58 L). Furthermore, the ``anaerobic{''} capacity was likely meaning fully (3.65 +/- 0.70 L) and very likely meaningfully (949.1 +/- 5.7 mL.kg(-1)) greater in running than cycling (3.81 +/- 0.71 L and 52.0 +/- 8.1 mL.kg(-1)). Additionally, the contribution of the phosphagen metabolism was higher (p = 0.001; large effect size) for running compared to cycling (1.6 +/- 0.3 L vs. 1.3 +/- 0.3 L respectively). Therefore, the ``anaerobic{''} capacity estimated by the sum of both oxygen equivalents from the glycolytic and phosphagen pathways during a supramaximal effort is influenced by exercise modality and is able to identify the difference in phosphagen metabolic contribution, based on the methodological conditions of this study.
