Brief summary
This is a pilot study to assess the feasibility of using treadmill desks (Workstations) within a Louisiana office workplace and to determine the effects of walking while working in overweight or obese, sedentary individuals.
Detailed description
Eligible participants will be randomized by chance to the WorkStation Intervention Group or to a Usual Working Condition Group. The WorkStation Intervention Group will be asked to walk for up to 1.5 hours per day during the work week of Monday through Friday on the treadmill. Participants will complete two sessions per day for up to 45 minutes per session, tracking time and speed. Usual Working Condition Group will be asked to continue working in usual environment and accustomed manner. Regardless of which group the participants are assigned to, the participants will be asked to complete baseline and follow up assessment visits. Months 3 and 6 for approximately 1 hour for Body measurements (height, weight and waist circumference), body fat percent, gait speed, questionnaires, and accelerometry.
Interventions
BEHAVIORALWorkStation
Participants will be asked to attend 2 scheduled sessions per day of treadmill walking, which will replace their sitting desk time. Participants will complete 2 sessions per day for 6 months.
BEHAVIORALUsual Working Condition
Participants will be asked to continue working at their desk in their usual manner.
