  1. Peak power, mean values maximum wattage; SCoV, group with SARS-CoV-2; noSCoV, group without SARS-CoV-2; SBP, systolic blood pressure (3-min interval); DBP, diastolic blood pressure; RPE, rating of perceived exertion; HR, heart rate; SV, stroke volume; SW, stroke work; VE, ventilation; V̇O2, oxygen uptake; LAC, blood lactate concentration; n2p, partial eta-squared
  2. *Significant differences, the values are given as the means and standard deviations for comparison at the 125 W stage and maximum output (post-test)
