Inactivity and sedentary behavior are major health concerns, exacerbated by the amount of time individuals spend at work. Purpose: To examine if 30-60 minutes of daily under-the-desk bicycle (UDB) use while working for 8 weeks helped sedentary and physically inactive adults reach the U.S. physical activity guidelines (PAG) and improve perceptions of wellness and job satisfaction. Methods: Subjects (n=22, average age=45.3 yrs, average BMI=30.2 kg/m2) cycled for 30-60 minutes on workdays for 8-weeks at a self-selected intensity level of 2 or 3 out of 8 total levels. Participants were advised not to engage in additional physical activity outside the study or modify their diet. Pre- and post-measures included self-reported height and weight, a 3-day food record, and the following questionnaires: Physical Activity Vital Signs, Workforce Sitting Questionnaire, Physical Activity Readiness Questionnaire+, Physical Activity Enjoyment Scale, Multidimensional Outcome Expectations for Exercise Scale, adapted-Health and Work Questionnaire, and behavioral beliefs construct. UDB use was reported weekly via the DeskCycle app. Participants were grouped based on HIGH (n=11) and LOW (n=11) cycling minutes and compliance, determined by the number of weeks cycling >150min. Results: UDB use increased physical activity levels to meet PAG in the HIGH group. Perceptions of overall health improved from baseline to post-intervention in both groups. The HIGH group had significant reductions weight (81.7+5.6 vs 77.9+5.5 kg) and BMI (29.3+1.5 vs 27.9+1.5 kg/m2) compared to the LOW group [(87.5+5.8 vs 88.2+6.2 kg) (31.1+2.0 vs 31.3+2.1 kg/m2)]. Change in aerobic activity was positively associated with compliance percent (p=0.041, r=0.44) and change in BMI with change in daily sedentary time (p=0.045, r=0.56). Conclusion: Our findings suggest that UDB use is an effective workplace intervention strategy to increase physical activity to meet PAG and aid weight loss in sedentary and inactive employees.
