Concurrent validation of estimated activity energy expenditure using a 3-day diary and accelerometry in adolescents
Scandinavian Journal of Medicine & Science in Sports, 04/02/2012
Machado–Rodrigues AM et al. – The 3–day diary was completed without any major problems and provided a reasonably valid alternative for assessing activity energy expenditure (AEE). Concordance between methods was slightly lower for individuals with higher values of AEE.
