Detaljeret beskrivelse
This study examines whether the demonstration of different intensity levels of physical activity by video in the context of a tablet PC (personal computer)-based survey can achieve a higher degree of concordance between self-reported and accelerometer-measured physical activity compared to an assessment without video demonstration. The recruitment of the study participants in the age range between 40 and 75 years takes place in a shopping center in the city Greifswald in Germany.
Informed consent consists of: (i) activity recording over 7 days using an accelerometer, (ii) completion of standardized questionnaires, (iii) participation in a standardized measurement of weight and height as well as waist and hip circumference.
Participants are asked to wear an accelerometer during the day for a period of 7 days. Subsequently, a questionnaire about the frequency, duration and intensity of physical activity in the last 7 days will be answered in the DZHK (Deutsches Zentrum für Herz-Kreislauf-Forschung)- examination center. Prior to the physical activity assessment the study participants are randomly assigned to the study conditions "Video" or "No Video" (ratio 1:1). Optionally, participants may receive feedback on their physical activity measured by accelerometer upon completion of the study.

Deltagergruppe / Arm |
Intervention / Behandling |
|---|---|
|
Eksperimentel: "Video"-group
Video group: Individuals in this group receive the intervention "Video demonstration of physical activity intensity levels".
They watch a 3-minute-video explaining and visualizing light-, moderate-, and vigorous-intensity levels of physical activity before completing a tablet PC-supported physical activity assessment at the DZHK-examination center.The video can not be skipped.
|
In the video demonstration, an approximately 50 year old male explains 1) light-intensity, 2) moderate-intensity, and 3) vigorous-intensity physical activity referring to differences in heart rate, breathing frequency and capability to talk normally.
Simultaneously, on a treadmill he demonstrates the body signs of the three intensity levels.
He gives examples and points out that there are individual differences in the intensity evaluation of comparable activities.

Ingen indgriben: "No video"-group
No video group: Individuals in this group do not receive the intervention "Video demonstration of physical activity intensity levels".
They complete a tablet PC-supported physical activity assessment at the DZHK-examination center without receiving a 3-minute-video explaining and visualizing the different intensity levels of physical activity.
