If you were running a marathon, which type of muscle fibers would be most useful to you?
A.
slow-twitch
B.
fast-twitch, type I A
C.
intermediate-twitch, type II B
D.
slow-intermediate twitch, type I B
Please select the best answer from the choices provided.
I think A, because it is very long distance. Fast twitch would be good for short sprints, intermediate for medium distance, slow intermediate for runs about a mile long, and slow for the longest distances.
