The Exercise is Medicine On Campus initiative promotes physical activity (PA) on campus. Although faculty and staff are campus role models, limited research has been performed on the importance of PA promotion in this population. Unique strategies are needed to promote PA in faculty and staff. Social support is an evidence-based behavioral strategy for increasing PA intervention adherence. Technology removes the need for in-person interaction by allowing virtual communication. PURPOSE: (1) Assess the feasibility and acceptability of a virtual social walking group and an in-person social walking group (2) Determine preliminary effects of both walking interventions on faculty and staff fitness. METHODS: This is a sub-study of the Exercise is Medicine initiative on the University of Arkansas campus in an effort to track PA and its association with health, student success, and work satisfaction. Twenty-nine faculty and staff members (47.3 years ± 12.6) walked for 150 minutes per week for 4 weeks. The virtual group (n=16) used a fitness tracker to log PA and virtual messaging for group interaction. Research staff provided little facilitation of virtual group interaction. The in-person group (n=13) met 5 days per week, walked for 30 minutes, and was encouraged to perform walking tasks when unable to attend. A research aide led each walk and facilitated conversation. RESULTS: Three participants were excluded due to missing data. At baseline, BMI for males (n=5) was 28.9± 3.7 and was 31.5± 8.1 for females (n=21). 50% of participants were classified as obese. The average aerobic capacity (VO2 max) of males was 28.5± 6.1 ml/kg/min, and average VO2 max of females was 24.2± 6.9 ml/kg/min. On average, virtual participants walked 177.1± 46.7 (range 101.4 to 267.3) minutes per week. 37.5% of participants met recommendations all 4 weeks. In-person participants attended an average of 82% (range 60 to 100%) of walking sessions. A paired t-test showed VO2 max of participants significantly improved (p=0.035) after intervention. Participants reported high satisfaction with the program. CONCLUSIONS: Both walking groups were feasible and acceptable among university faculty and staff, and aerobic fitness improved. Future research should assess long-term effects of PA interventions on all components of fitness of faculty and staff.
