Athletes with higher proportion of red fibres in their muscles are better equipped for which one of the following ?

Muscle fibers are classified into slow-twitch (Type I) and fast-twitch (Type II) categories. Red fibers, or Type I fibers, derive their color from high concentrations of myoglobin, which facilitates oxygen transport [t2][t6]. These fibers are rich in mitochondria and capillaries, enabling efficient aerobic respiration to produce ATP over long periods [t1][t7]. Consequently, red fibers are highly fatigue-resistant and ideally suited for endurance activities [t1][t2]. Among the given options, swimming is an endurance-based sport that requires prolonged exertion, making it the activity where athletes with a higher proportion of red fibers excel [t2][t9]. In contrast, sprinting, shot put, and short activities rely on white, fast-twitch (Type II) fibers, which generate rapid, powerful contractions through anaerobic metabolism but fatigue quickly [t1][t8].
