Abstract
The World Health Organization estimates that the world population over 60 years of age will increase from the current 841 million to two billion by 2050, making chronic diseases and the welfare of the elderly the new global public health challenge. A great scientific question unanswered in exercise science, which has a strong relation with this context, is the type of training that can generate greater benefits in each individual; although companies already sell genetic tests for this purpose, they fail to satisfy key criteria for scientific validity. The studies in the literature used only aerobic physical exercise, did not compare different types of stimuli, and did not associate data from global genetic variants to DNA methylation profile. The main purpose of this study is to evaluate anthropometric measures, blood pressure, bone mineral mass, muscle mass, body composition (DXA), maximal oxygen consumption, tests of muscular strength, functional performance, quality of life, and blood variables in women of 50 to 70 years and analyze: a. the effects of combined versus multicomponent physical exercise acutely and chronically on the global blood DNA methylation profile through Illumina's 850k Infinium MethylationEPIC BeadChip; and b. global genetic variants (Infinium Global Screening Array-24 v1.0 BeadChip of the Illumina platform) and methylation profile of blood DNA following a single session of physical exercise as predictors of magnitude of response in each of the two training protocols. This study will allow the achievement of subsidies for a paradigm shift associated with the prescription of personalized physical training. (AU)
