Habitual physical activity and resting heart rate variability in nipo-brazilians practitioners and non practitioners of PARK GOLF
AbstractThe aims of this study were to compare the habitual physical activity (HPA) level by means of steps.day-1 and the resting heart rate variability (HRV) parameters of nipo-brazilians practitioners (GPG) and non-practitioners (GNP) of Park Golf and verify the correlations between HPA and HRV. Thirty three subjects of both genders (68.2±6.3 years) participated of this study, being 20 subjects in GPG (68.3±6.3 years) and 13 in GNP (68.2±6.4 years). The subjects wore the pedometer for one week to measure the HPA. The HRV was analyzed beat-to-beat at rest in the supine position using a heart rate monitor and the respiratory frequency was controlled in 12 respiratory cycles per minute. The HPA level was higher in GPG when compared to GNP. There were no differences in the HRV between groups. Regarding gender, women presented higher mean steps.day-1 and parasympathetic indices of HRV. Men presented higher sympathetic indices. The HPA level was significantly correlated with body mass index (BMI) and with the mean R-R intervals. The greater HPA level reported in GPG was not sufficient to induce a more favorable resting HRV than in GNP.
