Effect of physical practice intensity on heart rate variability in post menopausal women

Abstract:

Aim. - Study was to asses the heart rate variability related to the physical practice intensity in post menopausal women. Method. - Time domain measurement of heart rate variability has been realised from the electrocardiogram at rest and during exercice in 3 groups of 6 women: untrained, active and trained. At rest, no significant difference betwen groups appears. But, in the standing position, RR interval and the dispersion around RR interval decrease in trained group only. During submaximal exercise, this dispersion is more elevated in active and trained groups. Conclusion. - Physical practice induces a higher response of sinus node to vagal modulation during standing position and submaximal exercise. © 2003 Éditions scientifiques et médicales Elsevier SAS.
