Exploring Intensity of Activity throughout the day among overweight/obese adults participating in a structured physical activity program

Abstract

Implementation of a physical activity program focused on moderate intensity may affect changes in daily steps, time spent sedentary, and/or time spent in light and vigorous intensity amongst overweight/obese adults. Adults classified as overweight/obese were recruited to participate in a 12-week weight-loss program where they were encouraged to work up to 300 min/week of structured exercise. However, this paper only collected data from weeks 1-4. Participants completed the exercise prescription provided by the research team but were also encouraged to participate in any physical activity of their choosing. Participants were provided with a FitBit device to track their steps and intensity levels during exercise sessions. Data was collected on a weekly basis from the FitBit.com dashboard. This study found minimal changes in activity and sedentary time during weeks 1-4. The participants did, however, exceed their goal step count during the 4-week period. Data is still being collected to explore the effects of the implementation of a physical activity program amongst overweight/obese adults.
