Wearables using exercise-based algorithms provide higher accuracy in the estimation of maximal oxygen consumption (VO2max) than those based on resting conditions.
Wearables using exercise-based estimation seem to be optimal for measuring VO2max at the population level, yet the estimation error at the individual level still needs further improvement.
In this article, the Towards Intelligent Health and Well-Being Network of Physical Activity Assessment (INTERLIVE) network provides best-practice recommendations to be used in future protocols to move towards a more accurate, transparent and comparable validation of VO2max derived from wearables.
