Kinetics of oxygen consumption (VO₂) during the constant load test at the intensity of the first ventilatory threshold (VT₁). (A) In patients with SARS-CoV-2. (B) Control group. The orange line (circles) corresponds to the data collected by the patients with SARS-CoV-2. The blue line (circles) corresponds to the data collected by the control group. The solid blue line corresponds to the assumed steady state of expected VO₂ at an intensity of VT1 in the patients with SARS-CoV-2. The solid orange line corresponds to the assumed steady state of expected VO₂ at an intensity of VT1 in control group. Data for VO₂ kinetics are provided as the mean of all participants. ★ Patients with SARS-CoV-2 significantly increased the slow component of VO₂ (VO_2SC) compared to the control group (p < 0.001). ∆VO_2FP increase in oxygen uptake in the fundamental phase, VO_2B baseline oxygen consumption.
