Question

Quizplus · Accepted Answer

Muscle dysmorphia is a subtype of body dysmorphic disorder, characterized by an obsession with building muscle mass and having a muscular physique. The individual is likely to engage in high-intensity, short-duration exercises targeting fast glycolytic (FG) muscle fibers, which are responsible for generating quick bursts of energy. Hypertrophy or enlargement of these muscles is expected as a result of the training. Therefore, option C (Hypertrophy of fast glycolytic (FG) muscle fibers) is the correct answer.
