Figure 3

RPE and Dyspnea during incremental running test. Data show RPE [6–20 scale] (upper panel) and dyspnea [1–10 scale] (lower panel). The black circles represent the cloth face masked (CFM) condition. The white circles indicate the unmasked control (CON) condition. There were no significant main effects of the mask factor on either RPE (P = 0.09, ηp2 = 0.25) or dyspnea (P = 0.20, ηp2 = 0.15). RPE and dyspnea tended to be higher in the FM condition than in the Unmask condition, but the differences were not significant (P = 0.14, ηp2 = 0.19, P = 0.06, ηp2 = 0.30).
