Pre: baseline; Post: postintervention; Post-Pre: change from baseline to postintervention; : eta-squared; VO2max: maximal oxygen uptake; MBS: the modified back-saver sit-and-reach test. The effect size in ANOVA/ANCOVA is represented by value of partial eta-squared () as very small (<0.01), small (0.01–0.05), medium (0.06–0.13), and large (≥0.14). †Adjusted for BMI at baseline and HRQoL role emotional domain at baseline.
