Characterization of Muscle Fiber Types in Humans with Obesity

Obesity is a complex metabolic condition characterized by excessive adipose tissue accumulation, often leading to adverse health outcomes such as insulin resistance, cardiovascular disease, and reduced physical function. This paper delves into the dynamic spectrum of muscle fiber types in obesity, highlighting their continuum nature rather than rigid classifications. We explore how alterations in fiber distribution, particularly an increase in hybrid fibers and glycolytic types, are more prevalent in obese individuals.
