Competing Interests
The principal investigator on the study (Coombes) received an unrestricted grant from Coca Cola that was used to partially fund this study. The purpose of the financial support was to support research investigating the effects of high intensity exercise on energy balance in participants with the metabolic syndrome. To assess energy expenditure we first wanted to conduct a sub-study to investigate the accuracy of wrist worn devices to collect these data – leading to the submitted manuscript. As an unrestricted grant, Coca Cola had no input or control over any aspect of the study. Our only obligation/communication to Coca Cola regarding this study is to notify them of what we had done. This does not alter the authors’ adherence to PLOS ONE policies on sharing data and materials. Professor Wisløff (co-investigator on the study) is Director of a company (Beatstack) that has developed and patented a smart phone application called the ‘Personal Activity Intelligence, PAI’. Beatstack is now partially owned by Mio Global. This has led to the PAI app only being able to utilise heart rate data from Mio devices. Mio are developing more wrist worn heart rate devices (as would be most similar companies) and Professor Wisløff is working with the company to develop these products as part of his involvement in the Beatstack company and his interests in the PAI app. None of the Beatstack products or the Mio company had any involvement in the study. This does not alter the authors’ adherence to PLOS ONE policies on sharing data and materials.
