“…The time of the sessions was 1 h and all variables are summarized as 1-min means at 1, 15, 30, 45 and 60 min (five stages). To assess the differences between N95 FFR and N95 FFR/EV with, and without, SM as an outer barrier at the two different intensity levels [1,15,30,45, 60 min]) repeated-measures analyses of variance (anovas) were performed for physiological variables (HR, fB, VT, V E , SaO2 and tcPCO2) using the values from the previous study report 12 as the control session for the comparisons. A 4 ¥ 2 ¥ 5 (FFR type ¥ work rate ¥ time) repeated-measures anova was performed to examine VD resp O2 and VD resp CO2 responses to the N95 FFR, N95 FFR/SM, N95 FFR/EV and N95 FFR/ EV/SM at the two different exercise intensities.…”
