Body Electric: a Pragmatic Trial Evaluating Movement Breaks As a Public Health Strategy to Mitigate the Harms of Prolonged Sedentary Behavior
In Brief
A clinical study evaluating Sedentary Breaks for Sedentary Behavior. Completed, enrolled 20,217 participants across 1 site.
Detailed Summary
The purpose of this pragmatic trial is to determine the implementation potential of three movement break doses (every 30, 60, or 90 min) under real-world conditions. The main questions it aims to answer are: * What is the feasibility, acceptability, appropriateness, and compliance to the tested movement break doses under real-world conditions? * What is the effectiveness of the movement break doses on improving mood, fatigue, and work performance? * What are the barriers of and facilitators to taking movement breaks across population subgroups (age group, sex, race/ethnicity, employment status, employment setting, and occupation). Researchers will compare differences in the primary (implementation metrics), secondary (mood, fatigue, and work performance), and exploratory (barriers/facilitators) outcomes across the three trial arms (movement breaks every 30, 60, or 120 minutes). Participants will: * Take movement breaks (5 minutes of walking at a self-selected pace) daily according to their dose condition (every 30, 60, or 90 minutes) for two consecutive weeks. * Complete daily surveys to report compliance, barriers/facilitators, and mood/fatigue/work performance. * Complete a survey battery at the end of the study to report implementation potential, rank/rate barriers and facilitators, and evaluate mood/fatigue/work performance. To address the study aims, the investigator will recruit 50,000 adults and will conduct a dosing study that concurrently tests three movement break doses. Participants will complete a 7-day baseline period to assess normal durations of sedentary behavior and movement, followed by a 2-week period during which they will be select a movement break dose to implement in their everyday life for the duration of the program. The break frequency x duration combination will include 5 minute every 30 minutes, 5 minutes every 60 minutes, and 5 minutes every 120 minutes. Work and leisure behaviors, mood, fatigue, and barriers/facilitators will be assessed via survey at enrollment, as well as via daily surveys during the baseline and intervention monitoring periods.

Timeline
Interventions
Participants recruited through a podcast series (Body Electric) produced by National Public Radio were asked to select one of three movement break conditions (5 minutes of movement for every 30-, 60-, or 120-minutes of sedentary time). Participants are asked to complete movement breaks during all waking hours on weekdays and weekends (i.e. 7 days a week). During movement breaks, participants are instructed to walk for 5 minutes in whichever way was most comfortable and safe (i.e. self-selected pace and location). Participants who use an assistive device such as a wheelchair or walker, were instructed to wheel, walk, or complete other convenient, comfortable, and safe types of movement such as upper body exercises with resistance bands, chair-based exercises, etc. No break reminders were provided, although participants were encouraged to set reminders in their phones or to utilize commercially available apps or wearable devices.
