Brief Summary

This study examines the effect of a video-based intensity level demonstration on self-reported physical activity in individuals aged between 40 and 75 years. Aim of the video demonstration is to achieve a better concordance of physical activity reports with accelerometer-based measurements.

Conditions

Physical Activity

Keywords

Video demonstration; Intensity levels; Physical activity; Self-report; Accelerometer

Outcome Measures

Primary Outcomes (1)

• Difference between physical activity measured by self-report and by accelerometry

  Measures: assessement via tablet PC (International Physical Activity Questionnaire-Short Form, IPAQ-SF) and objective measurement by accelerometry

  The accelerometer is worn for 7 days and then the IPAQ-SF is retrospectively answered for these 7 days.

Study Arms (2)

"Video"-group

EXPERIMENTAL

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.

Other: Video demonstration of physical activity intensity levels

"No video"-group

NO INTERVENTION

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.

Interventions

Video demonstration of physical activity intensity levels OTHER

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.
