Impact of ACE I/D gene polymorphism on blood pressure, heart rate variability and nitric oxide responses to the aerobic exercise in hypertensive elderly

To analyze the impact of I/D polymorphism of the angiotensin-converting enzyme gene on the responses of 24 h blood pressure, heart rate variability and nitric oxide after moderate aerobic exercise session. Twenty seven hypertensive elderly were genotyped for the I/D polymorphism of the angiotensin-converting enzyme gene (D/D: n = 9; I/D: n = 9; I/I: n = 9) and performed a bout of aerobic exercise at 90% of anaerobic threshold. Measurements of...
