Question

reduction in blood flow to a muscle fiber would have the greatest effect on

slow oxidative fibers

both slow and fast oxidative

fast glycolytic

fast oxidative fibers

Explanation:

Slow oxidative fibers rely on aerobic respiration (which requires a good blood supply for oxygen and nutrient delivery). Fast glycolytic fibers mainly use anaerobic glycolysis (less dependent on continuous blood - flow for oxygen). Fast oxidative fibers have some aerobic capacity but not as much as slow oxidative fibers. Since slow oxidative fibers are highly dependent on a continuous blood supply for their energy - generating aerobic processes, a reduction in blood flow would most severely impact them.

Answer:

slow oxidative fibers
