Biology of Running-Sept 7
September 7th, 2008
Fast-twitch muscles are used in proportion to the amount of work that needs to be done. Sprinters need mostly fast-twitch muscles because they need short spurts of muscle contractions than the average person. An increase in adrenaline and in neural stimulation will lead to an athlete's peak performance. This is a result of the mental energy igniting electrical impulses to the muscle. In turn, this means an increase in muscular tension.

I played various sports in high school. I was fast–good at sprints in track–but had little endurance. So do you think this might be explained by types of muscle (i.e., proportions of fast-twitch and slow twitch)? Seems I recall reading an article about this. What do you know?
Of course I could have worked on my endurance more.
You’re just reminding me how much I need to start running again, it has been 15 years now.
Also, in order for this to go into the course blog you need to tag it as biol12108sec2, I see you made a category with this tag, but I actually added the tag. If I’m confusing you, email at jgroom_at_umw.edu and I’ll explain.
Mr Killian-
You probably had more developed fast twitch muscles than slow twitch. There is definitely a proportion issue here. This is why most sprinters are not as great at cross country as they are at the 100m dash.
