Brief Summary

The purpose of this study is to:

1. 1.Evaluate the relative efficacy of a treadmill desk intervention on light physical activity and sitting behaviors at work over four weeks;
2. 2.Evaluate the relative efficacy of a treadmill desk intervention on the cardiovascular risk profiles (blood pressure, body weight, body fat percentage) over a four-week period.

Conditions

Sedentary Lifestyle; Risk Factor, Cardiovascular

Study Arms (2)

Usual Desk

NO INTERVENTION

participants will work at their usual desk for four weeks.

Treadmill desk

EXPERIMENTAL

Participants will be asked to use a treadmill desk for a minimum of 30 minutes per day for four weeks (Participants will sign up for a total of 30 minutes each day). Additional time may be spent on the treadmill, time permitting (two treadmills will be available to up to 10 people over the four week period).

Other: Treadmill desk

Interventions

Treadmill desk OTHER

A standing height desk with a treadmill attached.

Also known as: ActiveStation Treadmill desks

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: NONE
• Purpose: TREATMENT
• Intervention Model: CROSSOVER
• Sponsor Type: OTHER
• Responsible Party: SPONSOR

Model Details: A within-person, cross-over design will be used. Fifteen participants will take part in two conditions: 1) the treadmill desk: this intervention will ask participants to use a treadmill desk for a minimum of 30min per day for four weeks; and 2) the usual desk condition: participants will use their current workstation, as is, for four weeks. Participants will be randomly assigned to their initial intervention condition after baseline measures have been collected. In addition to the two condition months, there will be a one-week baseline period (to collected information on habitual activity level at work).
