Outline

Text

Objective: Young normotensive women offspring of hypertensive parents (FH+) have early several metabolic, hemodynamic and neuro-hormonal abnormalities [1]. High-intensity aerobic interval exercise (AIE) has shown to be more effective than continuous moderate exercise (CME) for reversing these abnormalities [2]. However, the acute and chronic effects of both AIE and CME on the blood pressure (BP) of FH+ have not been studied. The purpose of present study was to compare the acute and chronic effects of AIE and CME on 24-hour ambulatorial BP (24-h ABP) of young FH+ women.

Material/Methods: Thirty-two healthy sedentary FH+ women (25.0±4.4 years) randomized to a three times per week equal-volume AIE (80-90% of VO2MAX) or CME (50-60% of VO2MAX) regimen had their 24-h ABP analyzed at three different moments: 1) after a nonexercise control period (baseline), after the first session of AIE or CME (acute) and after 16 weeks of AIE or CME training (chronic). The baseline and acute 24-h ABP were performed in a random order.

Results: Baseline 24-h ABP was not significant different between groups (AIE: daytime systolic (S) BP=118.8±7.6, daytime diastolic (D) BP=75.8±3.8, nighttime SBP=104.9±6.1, nighttime DBP=61.4±4.8; CME: daytime SBP=116.8±6.6, daytime DBP=73.9±5.5, nighttime SBP=102.8±5.7, nighttime DBP=59.5±5.1), and an acute session of AIE or CME did not change 24-h ABP significantly (AIE: daytime SBP=116.1±6.3, daytime DBP=74.3±5.8, nighttime SBP=102.0±6.0, nighttime DBP=59.6±5.1; CME: daytime SBP=115.8±7.2, daytime DBP=74.8±4.7, nighttime SBP=101.4±8.1, nighttime DBP=59.7±6.3). However, both AIE and CME were effective to improve (P<0.01) nighttime (but not daytime) 24-h ABP after 16 weeks of training (AIE: daytime SBP=116.5±6.4, daytime DBP=73.9±4.8, nighttime SBP=99.7±6.5, nighttime DBP=57.3±4.8; CME: daytime SBP=114.9±8.3, daytime DBP=72.9±4.0, nighttime SBP=99.3±8.1, nighttime DBP=56.5±3.4).

Conclusion: An acute session of AIE or CME did not change 24-h ABP of FH+ women. However, 16 weeks of both AIE and CME were effective to improve 24-h ABP of these young normotensive women at high familial risk for hypertension. These findings may have important implications for the prevention of inherited hypertensive disorder.
