3. RESULTS
1. INTRODUCTION
Amount of steps
Smartwatches are increasingly popular with both consumers and researchers
Function to track physical activity and sedentary behavior using various variables such as amount of steps, minutes of physical activity, energy expenditure, heartbeat,…
Consumers attach great importance to what is stated about their activity level by these devices
Are these devices accurate?
r = 0,885
p < 0,001
r = 0,847
r = 0,892

AIM
Investigate the criterion validity of these devices in free living conditions for measuring:
Time of moderate-to-vigorous physical activity (MVPA)
Amount of steps
Sample
Measures
Criterion (concurrent) validity:
Huawei Polar Asus Fitbit Criterium = Actigraph GT3x+ VS
Participants wear 2 watches at the same time (on the wrist of the non-dominant hand) in combination with an Actigraph (on the right hip)
For 2 consecutive days during wake time (no water-based activities)
All participants wear all 4 watches (2 times 2 days)
All possible combinations of watches are made
2. METHODS
r = 0,757
p < 0,001
36 healthy participants
(20-65 years)
18 male
Physically active (n=9)
Physically inactive (n=9)
18 female
Time of moderate-to-vigorous physical activity

Fitbit
r = 0,615
p < 0,001
r = 0,547
r = 0,477
r = 0,385

4. CONCLUSION
All four watches show high validity for measuring steps.
For measuring MVPA validity is less high: Asus Zenwatch 3 shows low validity. Polar M600 and Huawei Watch show moderate validity and Fitbit Charge is the only one showing rather high validity for measuring MVPA.
