Sprinters Diet – Important Considerations

There are 2 types of muscle fibers – slow-twitch and fast-twitch. Slow-twitch muscles have a high blood supply and plenty of mitochondria (energy providing structures in cells that convert food into an energy source the cells can utilize) and myoglobin (oxygen and iron binding muscle protein that provides cells with oxygen). Therefore they are very fatigue resistant. Slow-twitch muscles are important for endurance athletes for example.
