Abstract
Background. Highlights High-Intensity Long Interval Training (HILIT) and Sprint Interval Training (SIT) to morpho functional improvement and reduce effects of Metabolic Associated Fatty Liver Disease (MAFLD) and the Metabolic Syndrome (MS). Objective. This study aims to verify the effects of HILIT and SIT on physiological and pathological markers of MS and liver health in adults submitted to 12 weeks of training. Methods. A randomized clinical trial was carried out with a design for two groups, HILIT and SIT Groups. The sample consisted of 38 physical activity practitioners male adults aged between 30 and 55 years (42.75 ± 8.26). Body composition assessments, cardiac stress tests, measurements of blood pressure (BP), and blood samples were analyzed: triglycerides (TRIG), high-density lipoprotein (HDL-C) and glucose (GLU) and liver damage: Albumin (ALB), Bilirubin (BIL), Aspartate Aminotransferase (AST), Alamine Aminotransferase (ALT), Gamma Glutamyl Transferase (GGT). Results. For HILIT there was a significant intragroup improvement in the parameters of fat mass, lean mass, body mass index (BMI), visceral adipose fat (VAT), GLU, ALB, Direct Bilirubin (DB), distance run, and oxygen consumption (VO2). For SIT there was a significant intragroup improvement in the parameters of VAT, GLU, ALB, DB, GGT, and distance run. There was a significant difference in the intergroup comparison only for BP in favor of the SIT group. Conclusions. We conclude that 12 weeks of HILIT and SIT interval training were able to produce positive effects on body composition variables, aerobic capacity, Metabolic Syndrome, and Liver Health in physical activity practitioners adult men, with better results for HILIT in this population.
