Key result
Short-term high-intensity interval training (HIIT) induced superior improvements in cardiac autonomic nervous system activity compared to moderate-intensity continuous training (p<0.0001).
Why the study?
Does short-term high-intensity interval training improve cardiac autonomic function compared to moderate-intensity continuous training in children?
Population
109 children aged 10–13 years (mean 11.07 ± 0.81), 39% boys and 61% girls.
Comparison

Design

Short-term HIIT may enhance autonomic function more than MICT in children; leaves open confirmation in RCTs and clinical outcome data.

Short-term high-intensity interval training induces superior improvements in cardiac autonomic nervous system activity compared to moderate-intensity continuous training in children.
Biljon et al. (2018) conducted an observational in Children (n=109). High-intensity interval training (HIIT) vs. Moderate-intensity continuous training (MICT), combined HIIT/MICT (ALT), and control was evaluated on Heart rate variability (HRV) parameters including lnSDNN, lnRMSSD, and lnSD1 (ES 2.22, 2.69, and 2.69, p=<0.0001). Short-term high-intensity interval training (HIIT) induced superior improvements in cardiac autonomic nervous system activity compared to moderate-intensity continuous training (p<0.0001).
