Objective: To evaluate the effect of a multicomponent physical activity program, compared with the usual medical practice, to reverse prefrailty by Fried in people over 70 years, one year after the end of the intervention.~Location: primary care setting (Madrid Region).~Population: non-dependent and pre-frailty patients ≥ 70 years old, who attend the health centers included in the study.~Design: Randomized parallel group multicenter clinical trial. Randomization unit and Unit of analysis: Patient.~Intervention: multicomponent physical activity program (MEFAP) with 12 weekly sessions of an hour and a half which includes 1) briefing 2) exercises for improving aerobic resistance, muscle strength, proprioception -balance and flexibility and 3) delivery of exercise chart to do at home (two times per week).~Main measures: Main variable: pre-frailty according to Fried phenotype. Secondary variables: sociodemographic, clinical and function variables; adherence, user satisfaction, quality of life.~Analysis: It will be carried out an analysis by intention to treat comparing the retrogression from pre-frailty (1 or 2 Fried criteria) to robust (0 Fried criteria) at the end of the intervention, 6 months after the intervention and one year after the intervention. Cumulative incidence, Relative Risk and Number Needed to Treat with a 95% Confidence Interval. A Generalized Estimating Equation logit model will be adjusted to analyze the associated factors.
