Sixty men living with obesity will be recruited and randomly assigned to either a standard care group (N = 30) or an intervention group (N = 30). Eligible participants will be age 19 years or older, living with obesity (BF ≥ 28%), able to perform exercises, but not currently engaged in regular physical activities (150 min of moderate to vigorous aerobic activities + two sessions of RT per week). Participants will be asked to maintain their current dietary habits within the duration of the project.~Sample size calculations was done based on the anticipated change in the proportion of obese men to achieve the PA guidelines (minimum of 150 minutes spent at MVPA in a week in addition to two sessions of RT). It is predicted that the proportion of men living with obesity who meet physical activity guidelines (both aerobic MVPA and RT) in the RT+ group will increase to 26.2% (similar to lean counterparts) at follow-up compared with 0% increased for the control group. The alpha level and power of analysis were set at 0.05 and 80% respectively, considering a drop-out rate of 30% in each group. A total of 23 people per group were required, so investigators will recruit 30 per group.
Emerging evidences suggest that alternative obesity management strategies need to address gender preferences to adopt healthier lifestyles such as resistance training. It is hypothesized that more men living with obesity who will be exposed to a novel resistance circuit training program (RT+) for 12 weeks will more physically active, 48 weeks after the intervention compare with people who will not exposed to RT+ program.
