Baseline and 16-week follow-up with unadjusted means±SD and mean outcomes of the Intervention Group compared to mean outcomes in Control Group, beyond the difference already present at baseline, adjusted for clustering within training groups and centers, RER: respiratory exchange ratio, HRmax: maximal heart rate.
