Over 9 months, 49 potential participants were screened for eligibility of whom 40 (81.6%) were enrolled. They had a mean age of 66 years [SD 1.36], mean BMI of 32.9 kg/mFlow diagram of participant recruitment and completionBaseline characteristics of participantsStatistics are presented as mean and standard deviation (SD) for continuous variables or The target sample size of 48 participants could not be reached due to budgetary constraints, and the process of simple randomization resulted in a difference in the number of participants randomized to each group. During the study, some changes to the protocol were required. Following the prolonged absence of a participant, availability was added as an exclusion criterion, excluding those who were unable to attend two class times per week or those who had planned absences (e.g., trips away) of > 2 weeks during the 24-week timeframe. Furthermore, at the walking sessions, participants would walk at different pasts making a group size of 10 challenging to supervise. Therefore, trainers requested to reduce group sizes to 6–8. Over the 24-week study period (Table Adherence measures over the first 12 weeks (0–12) and the second 12 weeks (12–24) for those participants in the walking group (Safety was analyzed using adverse event rates which are shown in Table Reported adverse events during the studyAbbreviations:
