Regression analyses were conducted between V̇O₂max (uncorrected by body mass) and OUES (uncorrected by body mass), V̇O₂max/kg and OUES/kg, and V̇O₂max/kg and the V̇E/V̇CO₂ slope. Abbreviations: SEE = standard error of estimation, OUES = oxygen uptake efficiency slope; V̇E/V̇CO₂ slope = the regression slope between minute ventilation and carbon dioxide production; V̇O₂ max = maximal oxygen uptake
