Manipulação das variáveis metodológicas do treinamento de força com base nos diferentes tipos de fibras musculoesqueléticas

Abstract

The study aims to present the main characteristics of the different types of musculoskeletal fibers, the main mechanisms associated with recruitment and its correlation with the methodological variables of prescription of strength training. Exploratory bibliographic research based on books and scientific articles. The search was carried out on Google academic and physical libraries. It was found that, although the variables that preferentially manipulate the training volume (weekly frequency, number of exercises and series) do not establish a clear correlation with the priority hypertrophy of a certain type of fiber, they determine the magnitude of the increases in strength and hypertrophy. Among the variables that guarantee the emphasis on priority recruitment of the fiber type, the load intensity is the main one. Stimuli with an emphasis on the development of strength resistance and increased time under tension seem to favor priority hypertrophy of type I fibers, stimuli with an emphasis on the development of hypertrophic strength and increased metabolic stress primarily hypertrophy of type IIA fibers, and stimuli with an emphasis on the development of maximum strength, muscle power and increased mechanical stress generate priority hypertrophy of type IIB or IIX fibers.
