Background: The metabolic associated fatty liver disease (MAFLD) recognized as a component of the Metabolic Syndrome (MS) aggregate together risk factors with a multiplier effect for cardiovascular diseases (CVD), type 2 diabetes mellitus (T2DM) and It is characterized by criteria of central obesity, dyslipidemia, hyperglycemia, and hypertension, proving to be one of the greatest challenges for global public health. Among the most used training methods, safely planned to gain physical conditioning and improve body composition, High-Intensity Interval Training (HIIT) presents itself as a popular and adherent physical training method that save time. Objectives: This document refers to research through the application of different methodological actions. The first action refers to conducting a systematic review with meta-analysis according to the PRISMA methodology to analyze the effects of physical exercise on hepatic inflammatory biomarkers in adults: a systematic review and meta-analysis. The second action will investigate the effects of High-Intensity Long Interval Training (HILIT) and Sprint Interval Training (SIT) on physiological and pathological markers of metabolic syndrome and liver health in adults undergoing 12 weeks of training. Methods: This is an experimental study designed for two groups that will be evaluated pre and post-intervention periods. The sample will be composed of non-sedentary male military musicians from the Brazilian Army, residents in the Rio de Janeiro city, and Resende city, belonging to the age group between 30 and 55 years. Body composition assessments, anthropometric assessments, aerobic capacity assessment, systolic (SBP) and diastolic (DBP) blood pressure measurements, blood samples for analysis of physiological markers of MS: high-density lipoprotein (HDL-C), triglycerides (TRIG), and glucose (GLIC) and liver damage: Albumin (ALB), Bilirubin (BIL), Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), Gamma Glutamyl Transferase (GGT). Then the participants performed 12 weeks of intervention with a frequency of 2 to 3 times a week with the training equalization through the calculation of the Training Impulse (TRIMP) and after the intervention a new data were collected of all the study variables. Results: The HILIT improved (p<0.05) liver health, body composition, and aerobic capacity in the parameters of fat mass, lean mass, body mass index (BMI), visceral adipose tissue (VAT), GLIC, ALB, Direct BIL, distance run, and VO2, also promoting an important result of body recomposition reflecting on applicability for changing lifestyle for society. The SIT improved (p<0.05) the parameters of VAT, GLIC, ALB, Direct BIL, GGT, distance run, and DBP. Conclusions: The HILIT and SIT interventions provided positive responses on body composition, on the physiological and pathological markers of the MS and liver health in adults, with the HILIT observed to be more efficient than the SIT
