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
Experimental: Step Group
This group receives feedback about the daily amount of steps by means of a 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 Name: 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 Name: 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
- 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.
- 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.
- Percent of Participants Losing Fat Percentage [ Time Frame: One Year ]The amount of body fat is measured by bioelectrical impedance analysis (BIA).
- 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.
- Step Count [ Time Frame: One Year ]Daily number of steps
