What are the different kinds of muscle tissue?
There are three major types of muscle tissue in the body. There is red and white muscle tissue. Red, or slow twitch muscle fibers, are not very quick, but can hold a contracting longer. White fibers are fast twitch, meaning that they go from a relaxed state to a fully contracted state much more quickly than red fibers. There is a fixed amount of white muscle fibers in everyone’s bodies, meaning that the ability to produce speedy movement is largely genetic. Exercise will not alter this number of white muscle fibers. Training can chemically improve the efficiency of the existing fibers, though, therefore improving performance somewhat.
