A cluster randomized controlled trial to test the effectiveness of a theory-based and setting-based intervention in promoting strength training among older adults in Hong Kong

The primary aim is to test feasibility and effectiveness of a theory-based and setting-based intervention in increasing participation in ST (i.e. fulfilling the ASCM recommendation of at least two non-consecutive days each week, each time performing eight to ten exercises that target the major muscle groups, with 10-15 repetitions for each exercise) among Chinese adults aged 60 to 74 in Hong Kong. It is hypothesized that participants in the intervention group, as compared to the control group, will report more participants fulfilling the ACSM guidelines, and showing improvement in the secondary outcomes. Another hypothesis that differences in outcomes between the intervention and control groups would be mediated by changes in variables related to the HBM (i.e. perceived susceptibility and severity of sarcopenia, perceived benefits and barriers of performing ST, cues to action, and self-efficacy) and social support toward ST will also be tested.
