All: Men and women combined; BP: blood pressure; RRI: RR-interval; ln: natural logarithm; statistical analysis was performed using an unpaired student’s t-Test where baseline values were compared between men and women. * P < 0.05 and ***P < 0.005 statistical significant differences between men and women.
