Can the exceptional abilities of elite high jumpers (power athletes) and marathon runners be explained by having predominantly fast or slow muscle fibre types in key muscles? Which ONE statement reflects the MOST WIDELY accepted explanation? (Lecture: skeletal muscle, Chapter: fibre types)

Question

Can the exceptional abilities of elite high jumpers (power athletes) and marathon runners be explained by having predominantly fast or slow muscle fibre types in key muscles? Which  ONE  statement reflects the  MOST WIDELY  accepted explanation? (Lecture: skeletal muscle, Chapter: fibre types)

Answer

The question cannot be answered because we cannot measure the fibre type ratios in living athletes.

Answer

It is the high density of mitochondria present in both power and endurance athletes which determines their elite performance characteristics.

Answer

There is little individual variation in fibre type proportions.

Answer

Elite power athletes are
born with muscles which are all fast fibres, whereas elite endurance athletes have all slow fibres.

Answer

Elite power athletes like high jumpers are born with a higher
than 50% fast-fibre profile, and marathon runners have a higher than 50% slow fibre
profile in key muscles.
