Cardiovascular autonomic control in endurance-trained and sedentary young women

Summary This study aimed to investigate whether endurance‐trained (ET) female athletes demonstrate differences in cardiovascular autonomic control compared with sedentary controls. Eighteen healthy eumenorrhoeic subjects, nine trained (22·4 ± 3 years) and nine sedentary (21·0 ± 1 years), volunteered...

Description
Summary:Summary This study aimed to investigate whether endurance‐trained (ET) female athletes demonstrate differences in cardiovascular autonomic control compared with sedentary controls. Eighteen healthy eumenorrhoeic subjects, nine trained (22·4 ± 3 years) and nine sedentary (21·0 ± 1 years), volunteered for the study. Heart rate variability (HRV) and cardiovagal baroreflex sensitivity (BRS) measures were adopted to assess cardiac autonomic control. HRV was recorded for 30 min under both controlled (0·25 Hz) and spontaneous breathing conditions. Cardiovagal BRS was assessed using the Valsalva manoeuvre. Analysis of the HRV showed a longer R‐R interval (1089 ± 114 ms versus 865 ± 100 ms; P
