METHODS: 19 participants (ages 40-64) were randomized into a Breaks Group (BG) or a Walking Group (WG) for the 12 week intervention. The BG was asked to take 2-minute breaks every hour of sedentary time and the WG was asked to increase their walking to 10,000 steps per day, including at least 30 minutes of moderate-vigorous physical activity (PA) in chunks of at least 10 minutes. Physical activity, sedentary time, and breaks were measured pre- and post-intervention using minutes of moderate-vigorous PA (Actigraph GT1M accelerometers) and steps were also measured (Yamax SW200 pedometers). Blood glucose and Hemoglobin A1C levels were measured pre- and post-intervention. Researchers maintained minimal contact with participants during the intervention through weekly emails and bi-weekly phone calls. Analysis of Variance with repeated measures was used to make comparisons (p < 0.05). RESULTS: 12 participants completed all measurements. Moderate-vigorous PA increased over time (16.7 minutes per day, p = 0.043), along with a decrease in Hemoglobin A1C (1.6%, p = 0.033). Pedometer steps increased while sedentary time and fasting blood glucose decreased, but not significantly. There were no differences between groups. CONCLUSION: Both interventions resulted in improvement in moderate-vigorous PA and Hemoglobin A1C levels in adults with Type II Diabetes, however, no differences were observed between groups. The small sample size likely contributed to the inability to obtain significant results and future studies should include a larger sample size and incentives to promote compliance.Health and Exercise Science
