Short Editorial Farah HRV and Young Arq Bras Cardiol. 2020; 115(1):59-60 That said, the importance of assessing cardiac autonomic modulation is evident, given its association with cardiovascular risk factors even in a healthy sample. The study “Family History of Hypertension Impairs the Autonomic Balance, but not the Endothelial Function, in Young Soccer Players” 8 reinforces this finding. However, being a cross-sectional study with a small sample, it obviously has some limitations. Thus, further studies may consider expanding this investigation by increasing the number of athletes in the sample, including female ones. 1. Malpas SC.
