Effect of High-Intensity Interval Training on Body Composition, Cardiorespiratory Fitness, Blood Pressure, and Substrate Utilization During Exercise Among Prehypertensive and Hypertensive Patients With Excessive Adiposity.

Regular exercise training is a recognized lifestyle strategy to lower resting blood pressure (BP), but little is known about substrate metabolism in population with high BP. Thus, the purpose of this study was to investigate the effects of 16-weeks of HIIT on body composition, BP, cardiorespiratory fitness by O , and substrate utilization during exercise among prehypertensive and hypertensive patients with excessive adiposity. We also aimed to test the potential association between changes in cardiorespiratory fitness, substrate utilization during exercise and BP.

[High intensity interval training increases the utilization of fatty acids in subjects with overweight or obesity. A randomized study].

Introduction: the effect of high intensity interval training (HIIT) on fat utilization during exercise needs to be studied in depth. Objective: to determine the effect of HIIT training program in subjects with overweight or obesity on the use of fat during exercise, body composition and cardiovascular variables. The second objective was to compare the variables according to the duration of the program (i.
