FIGURE 2.

Cardiopulmonary parameters of male and female COVID-19 survivors in the ICU, hospitalized, and non-hospitalized groups. Note: data are expressed as the mean and standard deviation; Panel (A) = HR (heart rate); Panel (B) = VO₂ peak (peak oxygen consumption); Panel (C) = VE (ventilation); Panel (D) = VO₂/HR (relationship between oxygen consumption and heart rate); Panel (E) = distance; Panel (F) = VCO₂/VO₂ (ratio between respiratory exchanges); Panel (G) = RPE (rating of perceived exertion); * = significant difference between the non-hospitalized group and the ICU group; † = significant difference between the non-hospitalized and hospitalized groups. One-way ANOVA with Bonferroni post hoc test. Level of significance established = p < 0.05.
