Why the study?
Does higher aerobic fitness improve heart rate variability and recovery in young-adult Black men?
Does higher aerobic fitness improve heart rate variability and recovery in young-adult Black men?
In young-adult Black men, heart rate variability and recovery are independently related to body composition rather than aerobic fitness.
Body composition may warrant priority over aerobic fitness for autonomic markers in young Black men; hypothesis-generating and requires prospective trials before practice change.
