Heart rate monitoring to assess energy expenditure in children with reduced physical activity

Abstract

The aim of the study was to assess whether heart rate (HR) monitoring is suitable to estimate energy expenditure in spastic cerebral palsied (CP) children, who are known to have very low levels of daily physical activity. Total daily energy expenditure (TEE) predicted from HR recording(TEEHR, measured over 2 or 3 d) was therefore compared with TEE measured by doubly labeled water (TEEDLW, measured over 14 d) in nine children with spastic diplegia/tetraplegia (mean ± SD age 10.7 ± 1.6 yr). At group level, there was no difference in TEEDLW (7.4± 2.1 MJ·d-1) and TEEHR (7.4 ± 2.2 MJ·d-1). Spearman correlation between both methods was 0.88(P
