RESUMEN
This study aimed to investigate the impact of 12âweeks of high-intensity interval training (HIIT) on hemodynamic variables at rest and during exercise in patients with obstructive sleep apnoea. Twenty-six obese adults with moderate-to-severe OSA (AHIâ=â42â±â22.9âe/h) were randomly assigned to HIIT or a control group. Sleep parameters, ambulatorial, aortic, and during-exercise SBP and DBP were assessed at baseline and after 12âweeks. Generalized estimated equations assessed differences between groups over time. When compared with control group, HIIT reduced AHI (17.1â±â6.2; e/h, P â<â0.01), SBP nighttime (10.2â±â5.0âmmHg; P â=â0.034), DBP nighttime (7.9â±â4.0âmmHg; P â=â0.038), DBP aortic (5.5â±â2.9âmmHg; P â=â0.048), and SBP max (29.6â±â11.8âmmHg; P â=â0.045). In patients with OSA, 12âweeks of HIIT decreases sleep apnoea severity and blood pressure in rest and during exercise.
