The hypothesized moderation model. Intervention effect (mean difference in change between low-to-moderate intensity (LMI) and high intensity (HI) training) on peakimal oxygen uptake (VO₂peak) post-intervention. The potential moderator variables investigated were baseline age, body mass index (BMI), cardiorespiratory fitness (CRF), hours in moderate-to-vigorous physical activity (MVPA), physical fatigue, chemotherapy treatment (yes/no), and adherence to the endurance training. Each of the potential moderator variables was included in the regression model one at a time, resulting in a total of seven models.
