Abstract

Introduction: To estimate the effectiveness of two physical activity programs on NAFLD.Methods: Participants come from a survey conducted in southern Italy. Subjects with moderate or severe NAFLD were invited to participate. After giving informed consent, they completed a questionnaire, underwent ultrasonography and anthropometric measurements. Then they were randomized an Aerobic or a Combined Exercise program and followed up for six months. The first group followed a program of moderate aerobic activity lasting 30 minutes, 5 days per week. The second group did aerobic training with the addition of muscle training involving the large muscle groups, stimulating them to make more intense efforts, for a duration of 60 minutes, at least, 3 days a week. Compliance with the programs was measured. A mixed linear model was applied to the data.Results: Compliance with Aerobic Exercise was homogeneous and increased over time. Combined Program compliance was equal to 100%. There was no significant difference in the NAFLD mean score by treatment at baseline and after six months. However, there was a significant reduction in the NAFLD mean score for treatments after six months. The NAFLD measured score was reduced by 22% in the Aerobic treatment group when confronted with the other program. In the Combined program, after 6 months, results showed to be less effective than the Aerobic Exercise in reducing the NAFLD score.Conclusions:  An aerobic exercise program is a realistic intervention which could be included as a part of primary prevention of several chronic diseases.Introducción: Estimar la eficiencia de dos programas de actividad física sobre la NAFLDMétodos: Sujetos con NAFLD moderada o severa que habían participado a un estudio de pobación en el sur de Italia fueron invitados a participar. Fue completado un cuestionario, se tomaron medidas antropométricas y se realizó una ecografia hepática. Cada participante proveyó el consenso informato. Los participantes fueron aleatorizados a un programa aerobico (actividad aerobica moderada per 30 minutos, 5 veces a la semana) o un programa mixto (aerobico más entrenamiento de la fuerza de los grandes grupos musculares, 60 minutos, tres veces a la semana). Fue medida la adherencia a los programas y se aplicó un modelo linear mixto a los datos.Resultados: El programa aerobico tuvo muy buena adherencia y esta aumentó con el tiempo mientras el programa mixto tuvo 100% de adherencia. No hubo diferencias estadísticamente significativas en el score de NAFLD al enrolamiento, mientras hubo diferencias estadísticamente significativas en el score medio de NAFLD después de 6 meses pero el score en el grupo del programa aerobico tuvo una reducción del 22% más intensa que el programa mixto. Este último programa por lo tanto se ha mostrado menos efectivo que el programa aerobico.Conclusión: Un programa de actividad física aerobica es un tratamiento realístico que podría ser efectuado no solo para la NAFLD sino también como prevención primaria de otras enfermedades crónicas.
