摘要：Purpose: The extent to which exercise-based interventions have spillover effects on the daily sedentary time of individuals is unclear. The objective of this study was to explore whether an integrative exercise-based intervention that had previously shown efficacy in increasing time in moderate-vigorous physical activity (MVPA) impacts the sedentary time of patients engaged in a cardiac rehabilitation (CR) program. Methods: We examined a 12-week randomized controlled trial intervention that featured music playlists enhanced with rhythmic auditory stimulation (RAS) as compared to usual care of CR only on the duration of MVPA time and sedentary time. Accelerometer-derived and self-reported MVPA time and sedentary time were used to examine the duration spent in each. The relationship between MVPA time and sedentary time was determined using Pearson’s Correlation Coefficient. Changes in MVPA time and sedentary time over the 12-weeks were determined using mixed effects repeated measures ANOVA tests. Results: The RAS-enhanced music intervention arm showed the highest duration of weekly MVPA time across groups but irrespective of intervention exposure, all participants were highly sedentary over the 12-weeks No correlation was found between sedentary time and MVPA time of all participants derived by accelerometer (r= -0.08, P=0.812) and self-report (r=-0.24, P= Conclusions: The majority of participants in an integrative intervention were successful at meeting MVPA recommendations but otherwise were highly sedentary. Accordingly, our findings reaffirm the needs for the need for separate strategies that focus on reducing overall daily sedentary time and promote regular MVPA.
