Why the study?
Does aerobic training improve resting heart period variability and vagal tone in postmenopausal women?
Does aerobic training improve resting heart period variability and vagal tone in postmenopausal women?
Aerobic training in postmenopausal women is associated with elevated resting vagal influence on the heart, as evidenced by increased heart period variability and lower resting heart rate.

Supports aerobic training association with higher vagal tone in postmenopausal women; leaves open prospective effects on heart period variability.
