887 THE EFFECTS OF CONCURRENT AEROBIC PLUS RESISTANCE EXERCISE ON BLOOD PRESSURE VALUES AND VARIABILITY AND ARE BLUNTED IN HYPERTENSIVE SUBJECTS WITH NONDIPPING NOCTURNAL BLOOD PRESSURE PROFILE

Abstract Background The purpose of this study was to investigate the effects of 12-weeks of concurrent aerobic plus resistance exercise training (CT) on short –term blood pressure variability (BPV) and BP values in hypertensive patients with nondippper BP nocturnal pattern and underlying coronary artery disease. Methods The study included 64 patients who were divided into two groups according to the nocturnal BP pattern: dipping pattern (29 pts) and nondipping (35 pts). Before starting CT and at 12 weeks patients underwent ergometric test, assessment of 1-repetiton mximun (1RM), and 24/h BP monitoring (24-h ABPM). Results after CT Twenty-four/h systolic BPV and daytime systolic BPV decreased significantly in the dipping group (-1.2 mmHg and -1.4 mmHg respectively) while they were unchanged in the nondipping group (-0.2 mmHg and -0.1 mmHg). Twenty-four/h systolic BP and daytime systolic BP decreased significantly in the dipping group (-8.3 mmHg and -8.5 mmHg respectively) while were unchanged in the nondipping group (-1.2 mmHg and -0.7 mmHg). Nighttime systolic BP and BPV was unchanged in both groups. Conclusion the effects of CT on BP and BPV are blunted in hypertensive subjects with nondipping BP pattern. Further studies are needed in order to find out more effectives training modalities for these patients
