Rob ter Horst’s scientific justification to choose the Polar H10 as his reference device is based on the paper:
RR interval signal quality of a heart rate monitor and an ECG Holter at rest and during exercise
https://pubmed.ncbi.nlm.nih.gov/31004219
of the Swiss Federal Institute of Sports in Magglingen:
But according to g.tec medical, they do not know of a manufacturer who has solved the problem of ECG motion artifacts, they can only be reduced. g.tec medical did not mentioned Polar who would have solved the problem of ECG motion artifacts with the Polar H10. And the Polar H10 does not full-fill the requirements for gold standard for heart rate measurments anyway, which include a 3 lead (or channel) ECG device.
The scientists from the Cleveland Clinic in Ohio have chosen another approach. They tested smartwatch accuracy against a 3 channel ECG on a treadmill up to about 15 km/h in the paper:
Accuracy of commercially available heart rate monitors in athletes: a prospective study
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6732081
As can be seen in the example of the ECG stress treadmill CS200 of Schiller medical Switzerland, it is possible to run we estimate to around 15 km/h on an ECG stress treadmill without motion artifacts:
The Schiller CS200 demo video is an indirect confirmation of the paper of the Cleveland Clinic in Ohio, that we can run on a treadmill up to about 15 km/h without ECG motion artifacts.
The CS200 costs around 20 000 USD depending on the equipment and is suitable for medical and research applications.
Can we not expect from a Postdoctoral Researcher at the Research Center for Molecular Medicine of the Austrian Academy of Sciences as Rob ter Horst is :

That he uses reference devices of the highest accuracy which fit to Rob ter Horst s scientific qualification?
Peter Gamma from www.petergamma.org has written a review about this and similar topics:
And the Tages Anzeiger Zurich newspaper recently wrote a critical article about fitness tracker accuracy. Studies show that many wearables are inaccurate and often unvalidated:
