Family history of hypertension increases the risk of an individual to develop hypertension, whereas moderate-to-high cardiorespiratory fitness has the opposite effect. However, the joint association of each on the development of hypertension is not well understood. We studied fitness and incident hypertension in 6278 participants who were given a preventative medical examination. Thirty-three percent reported a parent with hypertension, and there were 1545 cases of incident hypertension after a mean of 4.7 years. The presence of parental hypertension was associated with a 28% higher risk of developing hypertension after adjustments for age, sex, and examination year. After further adjustments for …

Heart Rate Variability And Exercise In Aging Women, Conrad P. Earnest, Steven N. Blair, Timothy S. Church

Background: Our group has shown a positive dose-response in maximal cardiorespiratory exercise capacity (VO_2max) and heart rate variability (HRV) to 6 months of exercise training but no improvement in VO_2max for women ≥60 years. Here, we examine the HRV response to exercise training in postmenopausal women younger and older than 60 years.

Methods: We examined 365 sedentary, overweight, hypertensive, postmenopausal women randomly assigned to sedentary control or exercise groups exercising at 50% (4 kcal/kg/week, [KKW]), 100% (8 KKW) and 150% (12 KKW) of the National Institute of Health (NIH) Consensus Development Panel physical activity guidelines. Primary outcomes …
