Descrição detalhada

non- Alcoholic Fatty Liver disease affects approximately 25% of the global population, with its prevalence increasing due to lifestyle changes such as poor diet and sedentary behavior. non- Alcoholic Fatty Liver disease is often associated with metabolic disorders, including insulin resistance, obesity, and type 2 diabetes. Emerging evidence suggests that alterations in gut microbiota may contribute to the pathophysiology of non- Alcoholic Fatty Liver disease, influencing liver function, inflammation, and metabolic regulation. However, there is limited research exploring the effects of interventions such as exercise and dietary changes on gut microbiota composition in non- Alcoholic Fatty Liver disease patients The findings of this study could have important clinical implications, particularly for developing tailored lifestyle interventions for non- Alcoholic Fatty Liver disease patients. As gut microbiota dysbiosis is increasingly recognized as a key player in the development and progression of non- Alcoholic Fatty Liver disease, interventions targeting microbiota balance could offer novel therapeutic approaches for managing this prevalent and potentially severe condition

Armas e Intervenções

Grupo de Participantes / Braço
Intervenção / Tratamento
Experimental: high intensity interval training and Mediterranean diet
This study will involve 20 patients with Non-alcoholic Fatty Liver disease undergoing individualized High-Intensity Interval Training for 12 weeks. The exercise regimen includes 3 sessions per week, featuring 3 sets of 3 minutes of high-intensity intervals at 70-90% heart rate reserve, with 2 minutes of active recovery between intervals. All exercise will be supervised on a treadmill, complemented by a Mediterranean diet.
Patients will engage in high-intensity interval training using heart rate reserve (HRR) to determine exercise intensity. The program includes three sessions per week for 12 weeks, featuring three 3-minute high-intensity intervals at 70-90% HRR, with 2 minutes of active recovery in between. Each 30-minute session will be treadmill-based under supervision, incorporating warm-up and cool-down periods. Participants will also follow a Mediterranean diet.
the composition of the Mediterranean diet, emphasizing that vegetables and fruits make up the largest portion at 35%, followed by whole grains (20%) and fish and seafood (15%). Legumes and nuts account for 10%, while olive oil and dairy products (cheese and yogurt) each contribute 7%. Smaller portions include poultry and eggs (4%) and red meat and sweets (2%), reflecting the diet's focus on plant-based foods, healthy fats, whole grains, and moderate consumption of animal products, with minimal intake of red meat and sugary foods.
Experimental: moderate intensity continous training and Mediterranean diet
This group will include 20 patients with non-alcoholic Fatty Liver disease they will receive moderate intensity continous training protocol consisted of 3× 3 min of moderate -intensity intervals at 40- 60% heart rate reserve for 30 min, in addition to Mediterranean diet.

Smaller portions include poultry and eggs (4%) and red meat and sweets (2%), reflecting the diet's focus on plant-based foods, healthy fats, whole grains, and moderate consumption of animal products, with minimal intake of red meat and sugary foods.

The program will be in form of:

  • Frequency: 3 sessions/week for 12 weeks.
  • Intensity: Moderate intensity continues training at 40- 60% HRR.
  • Duration: the session will last 30 minutes per session. Patients will be instructed to follow Mediterranean Diet.
Comparador Ativo: Mediterranean Diet
It is characterized by a high consumption of plant-based foods, such as vegetables, fruits, whole grains, seeds, nuts and legumes, and moderate consumption of protein-source foods such as fish and poultry. This diet is rich in monounsaturated fatty acids primarily from olive oil and olives, reduced fat dairy products and low red meat intake.

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
assessment of short chain free fatty acids butyrate and acetate
Prazo: at baseline and after 12 weeks
For short chain free fatty acids analyses, fecal sample will be separated. Applying four analytes, including total Short Chain Fatty Acids, acetate, propionate, and butyrate, will be targeted. Final concentrations will be calculated based on internal standards and are expressed as micromoles per gram of wet feces (μmol/g). Techniques and predictive approaches will be used across. gas chromatography will be used to quantify Short Chain Fatty Acids from fecal samples
at baseline and after 12 weeks
assessment of lipid profile
Prazo: at baseline and after 12 weeks
Fasting blood samples were collected after an overnight fast, and serum lipid levels were analyzed using standard enzymatic methods with an automated biochemical analyzer. The lipid profile included triglycerides, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol to assess lipid metabolism and cardiovascular risk.
at baseline and after 12 weeks

Medida de resultado
Descrição da medida
Prazo
assessment of quality of life
Prazo: at baseline and after 12 weeks
The short form-12 was scored using the standard scoring algorithm, which converts participants' responses into two norm-based summary measures: the Physical Component Summary and the Mental Component Summary. Each score ranges from 0 to 100, with higher scores indicating better health-related quality of life. The scores were calculated according to the official short form -12 scoring guidelines.
