WebAlthough muscle cells can change in size, new cells are not formed when muscles grow. Instead, structural proteins are added to muscle fibers in a process called hypertrophy, so cell diameter increases. The reverse, when structural proteins are lost and muscle mass decreases, is called atrophy. Age-related muscle atrophy is called sarcopenia. WebIdentify the primary changes that occur in skeletal muscle fibers in response to resistance training. Fast-to-slow shift in fiber type from type IIx to IIa (5-11% decrease in type IIx fibers with a corresponding increase in type IIa fibers following 20 weeks of training).
