  1. Key: SD indicates standard deviation; 95 % CI, 95 % confidence interval; ES, effect size (Cohen’s d; effect estimate/pooled baseline SD)
  2. Baseline means (SD) are based on 80 participants (intervention = 40; usual care = 40); post-interventions and within-group change at follow-up means (SD) are based on 70 participants (intervention = 37; control = 33)
  3. Except for the anthropometric measures, positive ES indicate effects in favour of the exercise intervention group
  4. Between-group effects were assessed using linear mixed model analysis, adjusted for the value of the outcome variable at baseline
