Resumo: |
The objective of this study was to evaluate the effects of NOS3 gene polymorphisms at -786T>C, 894G>T e Íntron 4 on the cardiovascular and biochemical parameters in middle-aged trained adults. Eighty six volunteers (fifty five normotensive [49,6±0,6 years] and third one hypertensive volunteers [52,9±1,2 years]) finished the study. The anthropometric (body mass index – BMI and waist circumference – WC), cardiovascular (office blood pressure - tycos®; ambulatory blood pressure - Dyna MAPA®; VO2 peak – one mile treadmill test; heart rate (HR) - Polar® RS 800CX) and biochemical (lipid profile, glycemia, creatinine - Cobas Mira Plus®, superoxide dismutase, catalase, nitrate/nitrite, malondialdehyde - Cayman Chemical, Ann Arbor, MI, USA). The NOS3 gene polymorphisms were performed by DNA extraction, followed by PCR (Mastercycler® Eppendorf) and genotype sequence (ABI 3500 Applied Biosystems). The aerobic exercise training was performed by 24 sessions (during 8 weeks), 3 times per week, 30-40min, in the maximal lactate steady state intensity. The crossover and double blind study were performed. Follow the main results: 1) Office blood pressure decreased for both normotensive and hypertensive groups in response of exercise training. The hypertensive group showed higher reduction of diastolic blood pressure than normotensive group (table 3 and figure 12). On the other hand, the ambulatory blood pressure did not change for hypertensive group in response of exercise training, whereas the normotensive group decrease both daytime and 24h (table 4 and figures 13,14). The cardiovascular HR (table 2 e figure 10), oxidative stress and NOx- (table 6 and figure 17) parameters did not explain the results. 2) The intron 4b/a polymorphism blunted both office (table 10 and figures 23,24) and ambulatory (table 11 and figures 29,30) blood pressure in response of exercise training. However, the -786T>C and 894G>T polymorphisms did not change both the... |
