Why the study?
Does the type of athletic training (explosive vs aerobic vs mixed) or race affect heart rate variability and cardiac autonomic function in athletes?

Cardiac autonomic function, as measured by HRV, is similar across different types of athletic training, though African American athletes may exhibit more favorable resting sympathovagal activity compared to Caucasian athletes.

HRV similarity across training types should not change practice; leaves open ethnic autonomic differences for prospective confirmation.
< 0.05) with respect to four HRV variables: pNN50, HF power, LF power, and LF/HF ratios. Explosive, aerobic and mixed athletes had similar cardiovascular and autonomic HRV results in all eight HRV parameters measured. All athletes reported LF and pNN50 values that were significantly correlated with two CVD risk factors: DBP and BW. Compared with Caucasian teammates, African American athletes demonstrated lower LF/HF and higher pNN50, indicating an even more favorable resting sympathovagal activity and healthy CV function.
