Workstation Pilot Study

Study Overview
=================
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Placebo Comparator: Usual Working Condition Group<br>Participants assigned to the usual working condition control group will continue to work in their usual environment and accustomed manner. The control group participants will have access to the Workstations at the completion of study. | Behavioral: Usual Working Condition<br>* Participants will be asked to continue working at their desk in their usual manner.<br>|
| Active Comparator: WorkStation Intervention Group<br>Participants will be asked to walk for up to 1.5 hours per day on the treadmill. This will be split into two 45 minute sessions per day. Behavioral support will focus on adherence to frequency (attending scheduled sessions). Participants self-select speed of walking and time (they have up to 45 minutes allotted, but may choose less as they like). | Behavioral: WorkStation<br>* 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.<br>|
