Validity and Reliability of the Polar M200 Activity Monitor (VAPO)

Validity and Reliability of the Polar M200 Activity Monitor to Measure Sedentary and Active Time

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.

Study Overview

• Status: Completed
• Conditions: Fitness Trackers; Healthy Persons
• Intervention / Treatment: Device: Polar M200

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.

Intervention / Treatment

Experimental: Healthy adult group; Sixty healthy adults, aged 18-65 years, will be included following written informed consent.

Device: Polar 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.
