Effects of muscular strength training programs on functional performance: systematic review

Abstract

Introduction: The amount of publications related to muscular strength and functionality calls on for a deep analysis of the results achieved before their professional implementation. Objective: To carry out a systematic review to design physical activity programs focused on muscular strength and functional training in sedentary people aged between 19 and 79 years. Materials and methods: The PRISMA, Chocrane and the University of York parameters were used for designing and conducting the systematic reviews. In addition, from strict specificity and quality criteria, 14 analysis categories were identified, from which general programming guidelines informed in this study arose. Results: 49 studies with evidence level 1+ (24%), 1-(33%), 2 ++ (4%), 2+ (29%) and 2-(10%) met the established selection criteria and allowed feeding the 14 proposed categories to make a summary of the contents. Conclusion: Increasing the effects of physical activity programs on muscular strength and functionality is possible if some basic programming variables (category) are identified and considered based on high-quality scientific evidence.
