Abstract Funding Acknowledgements Type of funding sources: None. The purpose of this study was to investigate the effects of 12-weeks concurrent aerobic plus resistance exercise training (CT) on short –term blood pressure variability (BPV) and BP values in hypertensive patients with non-dippper BP nocturnal pattern and underlying coronary artery disease. The study included 72 consecutive patients who were divided into two groups according to the nocturnal BP pattern: dipping pattern (33 pts) and non-dipping (39 pts). Before starting CT and at 12 weeks patients underwent six minute walk test, ergometric test, assessment of 1-repetiton mximun (1RM), and 24/h BP monitoring (24-h ABPM). After CT exercise capacity increased in both groups in a similar fashion. Twenty-four/h systolic BPV and daytime systolic BPV decreased significantly in the dipping group while they were unchanged in the nondipping group (between groups changes: -1.0 mmHg and -1.3 mmHg; p 0.02 and p 0.006 respectively). Twenty-four/h systolic BP and daytime systolic BP decreased significantly in the dipping group while were unchanged in the non-dipping group (between groups changes: -7.1 mmHg and -7.8 mmHg; p 0.004 and p 0.0002 respectively). Nighttime systolic BP and BPV was unchanged in both groups. Twenty-four/h diastolic BP presented small not significant changes in both groups. In conclusion: the effects of CT on BPV and BP were blunted in hypertensive subjects with non.dipping BP pattern
