About this study

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.

Treatment and study plan

Sitting breaks

Behavioral

Participants will take 2 minute physical movement breaks throughout a sedentary work day.

Primary outcomes

  1. Change in average area under the curve for glucose from a 10 day continuous glucose monitors

    Time frame: from baseline to post (8 weeks)

    Change from pre to post in average area under the curve for glucose from a 10 day continuous glucose monitors

Secondary outcomes

  1. Change in strength from pre to post

    Time frame: from baseline to 8 weeks

    As many reps as possible of squats wearing a weighted vest with 20% of their bodyweight

  2. Change in endurance from pre to post

    Time frame: from baseline to 8 weeks

    As long as possible in as low as possible wall sit (matching pre and post joint angles for participant)

  3. Change in one legged strength from pre to post

    Time frame: from baseline to 8 weeks

    As many reps as possible standing up from a seated position on one leg and sitting back down
