 Hemodynamic and Autonomic Evaluation All participants were instructed to maintain their daily eating routine on the day of the hemodynamic and autonomic evaluation. A Meditech Ambulatory Blood Pressure Monitoring-04, properly validated, was used for the hemodynamic assessment of systolic blood pressure and diastolic blood pressure in the pre- and post-intervention periods. A Polar RS800CX frequency meter Electo Oy, Kempele, Finland, also with demonstrated validity and reproducibility, was used for the cardiac autonomic assessment during the same period. The autonomic indicators examined were 1 linear methods in the time domain from absolute mean records of the R-R interval; and 2 methods in the frequency domain by spectral analysis through Fast Fourier Transform, including low frequency power 0.040.15 Hz in normalized units as a marker of sympathetic activity, high frequency power 0.150.40 Hz in normalized units as a marker of vagal activity, and the low frequency:high frequency ratio as a marker of the sympathetic-vagal balance. All indicators are described by the European Society of Cardiology, and all analyses were performed using the software Kubios Heart Rate Variability Analysis version 2.0 Biosignal Laboratory, University of Kuopio, Finland.
