Acute Effects of Reduced-Exertion High-Intensity Interval Training (REHIT) on Arterial Stiffness in Normal-Weight and Overweight/Obese Individuals

Background: Increased arterial stiffness (AS) following exercise may be associated with acute cardiovascular events. High-intensity play an important role in increase AS after exercise. Objectives: This study aimed to examine the effect of reduced-exertion high-intensity interval training (REHIT) on among individuals insufficient physical activity compared that normal-weight and overweight/obese individuals. Methods: Twenty-four young adults low were divided into group (n = 12, age 21.92 ± 0.79 years, body mass index (BMI) 20.97 1.21 kg/m2) 22.00 0.00 BMI 27.06 5.24 kg/m2). All participants performed REHIT (20 s × 2 all-out sprints a cycle ergometer for 10 min). Brachial-ankle pulse wave velocity (baPWV), heart rate (HR), blood pressure (BP), rating perceived exertion (RPE), affect responses assessed before 1, 30, 60 min. Results: Following REHIT, HR increased, baPWV decreased, which then returned baseline at min both groups. However, there was no significant difference between groups (P > 0.05). The RPE increased significantly < There change 0.05) Conclusions: Our main finding did not either or suggests can safely done physically inactive individuals, groups, adverse stiffness.
