简要总结
The proposed study will test the preliminary efficacy of a novel 12-week social cognitive theory-based intervention that will target reducing daily sitting time and increasing exercise participation among middle-aged working adults. This is a population highly susceptible to excessive sedentary time and low levels of exercise engagement. This two-arm randomized controlled trial (RCT) will examine the preliminary efficacy of decreasing sedentary time in addition to increasing moderate-vigorous intensity physical activity (MVPA) engagement, compared to a group which only receives MVPA promotion.

研究组 & 干预措施
Decrease Sedentary Time + Increase MVPA
Participants in this group will receive a 12-week, social cognitive theory-based intervention targetting reduction of daily sedentary time. This information will be delivered to them in the form of Zoom workshops, a program workbook, personalized step count goals, and a private social media page. The aim of this component will be to have participants displace their daily sedentary time with light-intensity physical activity, such as casual walking. The second component of this intervention will be increasing participants' weekly MVPA engagement. Participants will participate in 1 live, virtual aerobics-based exercise class per week and complete 2 additional sessions on their own time. Participants will build up to exercising 150 minutes/week (the federal physical activity recommendations).
干预措施: Decrease Sedentary Time + Increase MVPA group (Behavioral)
Increase MVPA only
Participants in this group will only receive the MVPA-promoting component (which will be the same delivery as the intervention group). Participants in this arm will participate in 1 live, virtual aerobics-based exercise class per week (held separately from the intervention group) and will complete 2 additional exercise classes on their own time. Participants will build up to exercising 150 minutes/week (the federal physical activity recommendations).
干预措施: Increase MVPA group (Behavioral)
