Methods: The Angiotensin converting enzyme (ACE) gene I/D, angiotensin II type1 receptor (AT1R) gene A/C and aldosterone synthase gene (CYP11B2) T/C polymorphisms of seventy-eight men with essential hypertension were tested by polymerase chain reaction (PCR). All patients performed three 40 min tests including a moderate-intensity aerobic exercise test with 60%VO2max (MAET), a low-intensity aerobic exercise test with 40%VO2max (LAET) and a resting control test (RCT). Ambulary blood pressure (ABP) including systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured before and after each trial. Results: The distribution frequency of all genotypes was coincident with Hardy-Weinberg equilibrium (P > 0.05). Compare with pre-test, blood pressure of all genotype groups was reduced (P < 0.05) after MAET and LAET, and no change after RCT (P > 0.05); after LAET, SBP of ACE-DD genotype group was lower than that of ACE-II/ID group (P < 0.05). After LAET, SBP and DBP in subjects with ≥3 variant RAAS polymorphisms were lower than those with ≤2 variant alleles; after MAET and RCT, there was no significant difference between two groups (P > 0.05). Conclusions: RAAS polymorphisms may interact with acute aerobic exercise induced blood pressure reduction. The effect of low intensity aerobic exercise reduced blood pressure in ACE-DD genotype carriers is better than that in ACE-I allele (II/ID); the effect of low intensity aerobic exercise reduced blood pressure in subjects with multiple (≥3) variant RAAS polymorphisms is better than that with
