Question

if gene therapy in the future would allow one to artificially alter the expression of muscle fibers for athletic success, which increase in fiber type would make the most sense for the following activities? labels ① drop zones dunking a basketball slow - twitch fibers (1/2) fast - twitch fibers (2/2) baseball pitching throwing standing broad jump marathon running competitive diving

Explanation:

Slow - twitch fibers are used for endurance activities, while fast - twitch fibers are for quick, powerful movements. Dunking a basketball, baseball pitching, throwing, standing broad jump, and competitive diving require quick and powerful muscle contractions, so fast - twitch fibers are ideal. Marathon running is an endurance activity, so slow - twitch fibers are more suitable.

Answer:

Dunking a basketball: Fast - Twitch Fibers
Baseball pitching: Fast - Twitch Fibers
Throwing: Fast - Twitch Fibers
Standing broad jump: Fast - Twitch Fibers
Marathon running: Slow - Twitch Fibers
Competitive diving: Fast - Twitch Fibers
