This study investigates the benefits of two different types of 2 minute activity breaks during sedentary workdays for people who sit for long periods of time in sedentary jobs.
For this study, participants are randomly assigned to one of two physical activity breaks and for 8 weeks are to do 4 per day and track their daily breaks and productivity. There are many measurements including: in-person strength assessments at baseline, 1 month, and 2 months; daily tracking of breaks; pre and post oral glucose tolerance tests; pre and post 10-day diet tracking; pre and post 10-day Continuous Glucose Monitoring with a Dexcom; genome with saliva at pre; and -omics at pre and post.
