Mean differences within group are in mean (95% CI), a negative change indicates a fall in average from baseline to 6 months
P-value: ^*p < 0.01, ^**p < 0.001
^aChanges of body composition variables during intervention or maintenance phase analysed using paired t- test
^bDifference of changes of body composition between intervention and control group measured using ANOVA
