Background and study aims
The workplace is an important potential setting for physical activity (PA) interventions (i.e. programmes). However, few workplace PA interventions take full advantage of work breaks and result in limited-to-modest success. Booster Breaks are organized work breaks that are designed to improve employees physical and psychological health, increase job satisfaction and improve work productivity. Booster Breaks have been developed to alleviate work-related stress and encourage more PA behavior in employees that may otherwise have sedentary jobs. Examples of Booster Breaks include short exercise or meditation sessions. The aim of this study is to test whether Booster Breaks increase PA among sedentary employees, compared with individualized PA work breaks and typical work breaks.
Who can participate?
Employees with sedentary office jobs from four workplaces in a large, urban southwestern U.S. city.
What does the study involve?
Participants are randomly allocated into one of three groups. Those in group 1 are assigned to the Usual Break (control) group. Those in group 2 are assigned to the Computer Prompt (individualized PA work breaks) group. Those in group 3 are assigned to the Booster Break group. The Usual Break condition includes usual or typical work break practices and behaviors. The two interventions are developed to be consistent with the WHO Healthy Workplace Framework and Model. The individualized Computer Prompt condition is designed to interrupt prolonged sitting time by introducing 3-minute breaks, 5 times per day. The group-based Booster Break condition is a peer-led, once-a-day, 15-minute PA session that guides employees through a series of stretching, strengthening, and aerobic movements followed by a brief meditation. Based on a participation rate threshold of 70%, workplaces were classified either as consistent or inconsistent implementers of the intervention. A number of physiological and behavioral measures are assessed before the study starts and 6 months later.

| Scientific title | Impact of Booster Breaks on physical activity among sedentary employees: a cluster randomized controlled trial |
| Study objectives | It was hypothesized that, compared with non-Booster Break participants, Booster Break participants will have significant improvements in: 1. Physiological measures (i.e., blood pressure, fasting lipids, triglycerides, and anthropometrics) 2. PA (increase) and sedentary behavior (decrease) 3. PA mediators 4. Employee and organizational psychosocial constructs |
| Ethics approval(s) | This study was approved by the appropriate IRBs and the University Committee for the Protection of Human Subjects |
| Health condition(s) or problem(s) studied | Physical inactivity, sedentary behavior, obesity |
| Intervention | Participants were randomized to the Usual Break (control group), Computer Prompt, or Booster Break condition. The Usual Break condition included usual or typical work break practices and behaviors. The two interventions were developed to be consistent with the WHO Healthy Workplace Framework and Model. The individualized Computer Prompt condition was designed to interrupt prolonged sitting time by introducing 3-minute breaks, 5 times per day. The group-based Booster Break condition was a peer-led, once-a-day, 15-minute PA session that guides employees through a series of stretching, strengthening, and aerobic movements followed by a brief meditation. |
| Intervention type | Behavioural |
| Primary outcome measure | 1. Lipid profile 2. Blood pressure 3. Height 4. Weight 5. International Physical Activity Questionnaire (IPAQ) 6. Pedometer readings Measures were taken at baseline and immediately after the intervention (i.e after 6 months) |
| Secondary outcome measures | Physical activity mediators and employee and organizational psychosocial constructs: self-report assessments at baseline and immediately after the intervention (i.e after 6 months) |
