Supports HR+ACC for more accurate PAEE estimation in children; extends validation data but leaves open clinical adoption.
Does accelerometry combined with heart rate monitoring improve the accuracy of physical activity energy expenditure prediction compared to accelerometry alone in children?
In children, physical activity energy expenditure prediction models using both heart rate and accelerometry are more accurate and have less systematic error than those using accelerometry alone.
Corder et al. (2007) studied this question.
