2.6. Randomization, Allocation, and Sample Power
Participants were randomized using a random sequence, according to the corresponding numbers received prior to the intervention, using a Microsoft Excel 365 software spreadsheet for distribution between groups. Allocation concealment occurred so that investigators or research participants did not know whether the next eligible participant would receive a treatment or control intervention. This was masked until such time as the intervention was initiated.A power of 94.54% was obtained considering the mean difference in body fat percentage between the groups (effect size = 1.64), bilateral α of 5%, and sample size of the groups. Calculations were performed using the GPower software version 3.1.9.7.
