May caution against single HRV measures in children; leaves open need for repeated assessments and age-matched controls in research.
What is the moderate-term reproducibility of heart rate variability during rest and light to moderate exercise in healthy children?
Heart rate variability measures in children demonstrate moderate to poor reproducibility over an 8-week period, especially during exercise, necessitating age-matched controls in future studies.
Leicht et al. (2008) studied this question.
