Muscle Activation during Exercise Reveals Specific Dynamics Profiles for Different Muscle Types

Article title: Universal spectral profile and dynamic evolution of muscle activation: a hallmark of muscle type and physiological state

Authors: Sergi Garcia-Retortillo, Rossella Rizzo, Jilin W. J. L. Wang, Carol Sitges, Plamen Ch. Ivanov

From the authors: “The uncovered universality among subjects in the spectral profile of each muscle at a given physiological state, as well as the robustness in the evolution of these profiles over a range of time scales and states, reveals a previously unrecognized multiscale mechanism underlying the differentiated response of distinct muscle types to exercise-induced fatigue and aging.” 

This study is highlighted as one of September’s “best of the best” as part of the American Physiological Society’s APSselect program.
