Abstract

INTRODUCTION: Sarcopenic obesity is characterized by a progressive decline in muscle mass and an increase in body fat, a condition especially present in the elderly. A significant improvement in metabolic parameters has been observed with the completion of taurine supplementation and also with the practice of physical exercise, but there are no studies associating the interventions mentioned above with the aim of analyzing the metabolic profile of elderly people with sarcopenic obesity. The metabolomics approach allows the study of a whole set of metabolites involved in a biological system. It is believed that taurine supplementation associated with physical exercise is capable of promoting positive contributions to the metabolic profile, investigated through a metabolomics approach. METHODS: The study will involve 60 elderly women with sarcopenic obesity who will be randomly distributed into 4 groups: 1) GPL, submitted to placebo supplementation (n=15); 2) GTAU, submitted to taurine supplementation (n=15); 3) GPL+EX, submitted to placebo supplementation associated with physical exercise (n=15) and 4) GTAU+EX, submitted to taurine supplementation associated with physical exercise (n=15). The interventions will take place for 16 weeks, collections and evaluations will be carried out pre and pos-intervention of functional capacity testing, resting energy expenditure, biopsy of white adipose tissue for analysis of gene expression and blood collection for analysis of the plasma concentration of taurine and of the metabolomic profile. Body composition, anthropometry and food consumption will be evaluated pre, during and pos-intervention. OUTCOMES: The synergistic effects of the proposed intervention are expected to improve the metabolic parameters, regarding the profile anti-inflammatory, antioxidant, lipid metabolism, body composition, and functional physical capacity in elderly women with sarcopenic obesity.
