The effects of the interventions will be analysed in two ways, namely from the data collected and by intention-to-treat analyses, where the last available value in the drop-outs will be carried forward to represent the missing data. Analyses of variance with repeated measures (2x4) will be employed to investigate the mean and interaction effects between the groups (intervention x control) and the time (pre-, post-interventions, and follow ups) for the primary physical activity level and mobility outcomes and the following secondary outcomes: muscular strength, exercise capacity, and SSQOL scores. Group descriptions will be presented as means and SD, and effect sizes at 95% confidence intervals will be reported.
