Speed Report: Fast Twitch for Football Speed - Can it be Produced?

Muscle fibers are made up of two different types of fiber composition, slow twitch fibers and fast twitch fibers. Skeletal muscles are made up of numerous individual muscle fibers called myocytes. Each myocyte contains many myofibrils, which are strands of proteins that can grab on to each other and pull. This shortens the muscle and causes muscle contraction. Of course, contraction can be very fast and dynamic or slower with endurance capabilities. When we think about football speed we natur...Login to Read More
