What muscles are for primary sprinting?

Question

i need to know what, i can work them during the off season for track. i would like to be explosive for the up coming year. if you have any other ideas please fell free to suggest them to, thank you for your time

Answer 1

all of them

Answer 2

Type IIa Fibers

These fast twitch muscle fibers are also known as intermediate fast-twitch fibers. They can use both aerobic and anaerobic metabolism almost equally to create energy. In this way, they are a combination of Type I and Type II muscle fibers.

Type IIb Fibers

These fast twitch fibers use anaerobic metabolism to create energy and are the "classic" fast twitch muscle fibers that excel at producing quick, powerful bursts of speed. This muscle fiber has the highest rate of contraction (rapid firing) of all the muscle fiber types, but it also has a much faster rate of fatigue and can't last as long before it needs rest.

Answer 3

thats a hard question its most likely to be the leg muscles but i could be wrong because the pro sprinters have muscle every where

Answer 4

I suggest you read up on "fast twitch" and "low twich" muscle fibres.  Fast twitch fibres fall into 2 categories:

Type IIa Fibers

These fast twitch muscle fibers are also known as intermediate fast-twitch fibers. They can use both aerobic and anaerobic metabolism almost equally to create energy. In this way, they are a combination of Type I and Type II muscle fibers.

Type IIb Fibers

These fast twitch fibers use anaerobic metabolism to create energy and are the "classic" fast twitch muscle fibers that excel at producing quick, powerful bursts of speed. This muscle fiber has the highest rate of contraction (rapid firing) of all the muscle fiber types, but it also has a much faster rate of fatigue and can't last as long before it needs rest.

There is some evidence showing that human skeletal muscle may switch fiber types from "fast" to "slow" due to training.

However, most of it is genetically pre-determined, i.e. people are born either sprinters or marathon runners....

Have you done any work on your actual sprint technique??  Look here:  http://www.brianmac.co.uk/sprints/

It also includes a weights program which as you would expect is primarily working your hamstrings, quads and glutes but way of squats, lunges clean and presses etc.

Good luck.
