Introduction: the frailty syndrome is currently described as a clinical state of vulnerability to stress and is related to adverse outcomes such as hospitalizations, falls and death. These changes result in physiological dysfunctions, clinical representations (loss of muscle mass and strength, weight loss, reduced gait velocity and low exercise tolerance), with consequent sedentary pattern. In this sense, some studies suggest exercise as a key in the treatment of this syndrome. Thus, the multicomponent training has gained prominence in this population, since it can improve the functional capacity and physical components, with the most significant results in the pre-frail elderly. In this context, it is important to assess the level of physical activity and sedentary pattern after a multicomponent training protocol, and the response to exercise in pre-frail elderly people. Objective: To evaluate the effects of a multicomponent training protocol in the performance of six-minute walk test (6MWT) and sedentary pattern in pre-frail elderly people. Methods: Will be evaluated 24 pre-frail elderlies, and distributed in two randomized groups: intervention group (IG - it will participate of the multicomponent training protocol for 16 weeks), and control group (CG - it will not participate of intervention activities). The evaluations will be conducted in 2 stages: pre-training and post-training Volunteers participate of anamnesis, resting electrocardiogram, 6MWT and use a triaxial accelerometer during seven days to measure of physical activity level. Will be evaluated walk distance and the number of stops in the 6MWT, as well as the variables of physical activity levels. The Shapiro-Wilk test will be used to verify the normality of the data. For the intragroup and intergroup comparisons, in pre and post-training, the ANOVA two way with repeated measures will be used. The chi-square test will be used for categorical variables. (AU)
