Brief summary

The aim of this study will be to investigate the validity of a consumer available activity tracker (Polar M200) in free-living conditions to measure sedentary time.

Detailed description

The aim of the present study is to evaluate the validity from a commercially available wearable Polar device. Consumer-based activity trackers are generally cheaper, designed for long-term wear and are less intrusive. Potentially, consumer-based activity trackers can be used for research purposes, but high-quality validation studies are needed. The aims of this study will be to assess validity of sedentary outcome measures of a Polar device during free-living conditions in comparison with the ActivPAL3TM activity monitor (AP; PAL Technologies Ltd, Glasgow, UK), which is considered the gold standard to measure sedentary time in free-living conditions.

Interventions

DEVICEPolar M200

Participants will have to wear the activity monitors (AP and Polar M200) for at least 7 days. Minutes spent in each activity type will be summed to a total day score. Participants will be instructed to do their regular daily life activities without limitation, but to note their main activity categories in an activity diary, with a main focus on cycling and participation in structured exercise.
