Differences were observed in PA after 4 months of training (n=49), time by group interaction effect (P=0.045; Table 2). The SE-UBR group increased LPA and the other groups decreased LPA, post hoc comparisons SE-UBR versus ED-UBR (P=0.018) and SE-UBR versus ED-Chair (P=0.019). The change in the time spent in LPA was +20.68±29.30 (95% confidence interval [CI] -2.36, 43.72) minutes/day for SE-UBR; -22.43±47.88 (95% CI -42.38, -2.47) minutes/day for ED-UBR; and -25.73±51.76 (95% CI -49.58, -1.88) minutes/day for ED-Chair. There were no changes in time spent in MVPA or sedentary activity. The effect size (Cohen’s d) for change in the time spent in PA (SE-UBR versus the combined groups of ED-UBR and ED-Chair) was large for LPA (1.14) and very small for MVPA and sedentary activity (0.02 and 0.10, respectively).
