Notes: Hourly performance ratios calculated on the basis of the physical activity (PA) parameters and the sedentary behavior (SB) parameters. Data of waking hours (6:00 a.m. – 11:00 p.m.), and leisure time (04:00–11:00 p.m.) were investigated by analyses of covariance (factor couple and couple-specific Δ BMI as covariate (1x2 ANCOVA)). All PA parameters showed significant differences between the investigated groups for waking hours and leisure time (*). In contrast, only one significant difference could be found for the SB parameter total time in bouts (*) for waking hours.
