Fig. 2

Heart rate (HR) and SaO2 changes during a series of four static handgrip exercise challenges, averaged for female and male groups. HR is from all 63 subjects, and SaO2 is from 58 subjects with artifact-free mean saturation data. a HR % change relative to baseline and c SaO2, averaged over four challenges (mean ± SE). Time points of significant within-group responses are indicated by blue xs (males) and red circles (females), and significant between-group differences in red-yellow asterisks, based on P < 0.05 with repeated measures ANOVA (RMANOVA). b Absolute heart rate and d SaO2 over series of four static handgrip exercise challenges, averaged separately over females and males with SE shaded
