Is there any correlation between quick reflexes and fast twitch muscle fibers?
In: Biology
Short answer: no, there isn’t.
Long answer: they have nothing to do with each other. Reflexes are by definition responses to a stimulus performed without conscious thought. Typically they shortcut the brain. Think of your nerves as a two way street with the only place for a car to make a u turn being in the spine or brain. A stimulus would be a car, traveling from say your knee up towards your spine and brain. It will turn around in the spine and be sent back down as an order to stretch out your leg.
Fast twitch muscle fibers are the type of muscle fibers used in short but powerful movements. Sprinting vs running a marathon. They exert more easily so your body will usually favor using slow twitch fibers until they become tired and then switches to the fast twitch.
