Heritability of HR and BP Response To Exercise Training in the HERITAGE Family Study.

Assessed the heritability of response to exercise training in resting blood pressure (BP) and heart rate (HR) among sedentary Caucasians comprising 98 families who completed an exercise training program. Results indicated that the trainability of systolic BP and HR in families with elevated BP was partially determined by genetic factors. Diastolic BP trainability was more a function of environmental effects. (SM)
