The Impact of Real-time Feedback on Physical Activity Patterns in Flemish Employees

The Impact of Real-time Feedback on Physical Activity Patterns in Flemish Employees: an Intervention Study

The aim of the study is to assess an increase of daily physical activity from electronic self-monitoring, to compare these values to the 10.000 step program, and to compare with real-time feedback with and without guidance from a Personal Coach.

Detailed Description

The purpose of this intervention study is to determine the effectiveness of continuous self-monitoring and real-time feedback from the SenseWear Armband (BodyMedia) alone and in combination with Personal Coaching to enhance physical activity and influence consciousness about its own physical activity patterns over a 12-month period in sedentary Flemish employees. The investigators hypothesize that the use of the feedback will increase awareness and subsequent physical activity levels of inactive office workers. Another hypothesizes is that the weekly meeting with a Personal Coach will add a controlling element and therefore employees of the 'coaching group' will have a higher physical activity level at the end of the intervention period compared to the other groups.

  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Placebo Comparator: Control group
This group receives no kind of feedback during the intervention period. The participants wear the SenseWear Armband for 4 weeks and results of the intervention are discussed after the 4 week intervention period.
Device: SenseWear Armband
Participants wear the SenseWear Armband for 4 weeks
Other Names:
  • SenseWear Pro3 Armband
  • BodyMedia, Inc. Pittsburgh, PA
Experimental: Step Group
This group receives feedback about the daily amount of steps by means of a pedometer.
Device: Pedometer
Participants receive a pedometer to determine their daily amount of steps. Every day they write down their amount of steps in a step diary.
Other Names:
  • Yamax Digi-Walker SW-200
Experimental: Display Group
Participants receive real time feedback on their energy expenditure, minutes of physical activity and step count by means of the SenseWear Display
Device: SenseWear display

Participants use the self-monitoring device (display) to aid behavior change via real-time lifestyle feedback targeting physical activity.

The display has a versatile design that allows it to be clipped to a shirt, bag or belt loop. The Display can help participants stay in sync with their daily goals.

Other Names:
  • BodyMedia® Display (Model DD100)
Experimental: Coaching Group
Participants receive real-time feedback on their energy expenditure, step count and minutes of physical activity by means of the SenseWear Display and weekly meet with a Personal Coach to discuss their progress
Behavioral: Personal Coaching
A weekly meeting with a Personal Coach to evaluate the physical activity patterns in daily life

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Physical Activity Level
Time Frame: One year
To account for differences in body size and composition, the 24-hour energy requirement (kcal/day) is expressed as a multiple of the basal metabolic rate per 24 hours by using the PAL value (PAL = total energy expenditure/basal metabolic rate). A desirable PAL includes the regular practice of physical activity at work or in spare time with an intensity and duration that will reduce the risk of becoming overweight and developing a variety of non-communicable chronic diseases usually associated as co-morbidities with obesity. This corresponds to PAL values of 1.75 and higher.
One year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Daily Energy Expenditure in Physical Activity
Time Frame: One year
Minutes of physical activity. Activities can be classified as moderate-intensity, vigorous-intensity or very vigorous-intensity activities based upon the amount of energy used by the body while doing the activity.
One year
Percent of Participants Losing Fat Percentage
Time Frame: One Year
The amount of body fat is measured by bioelectrical impedance analysis (BIA).
One Year
Stages of Motivational Readiness for Physical Activity
Time Frame: One Year
According to The Stages of Motivational Readiness for Change Model (SOC), individuals move through a series of stages as they adopt and maintain a new habit(Prochaska & DiClemente, 1983). Specifically, the stages include Precontemplation, Contemplation, Preparation, Action, and Maintenance.The relevant variables were assessed in a self-administered questionnaire.
