N2 - Abstract 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 Institutes of Health (NIH) Consensus Development Panel physical activity guidelines. Primary outcomes included time and frequency domain indices of HRV. Results: Overall, our analysis demonstrated a significant improvement in parasympathetic tone (rMSSD and high frequency power) for both age strata at 8 KKW and 12 KKW. For rMSSD, the age-stratified responses were: control,
