Study Question Eleven

• An average human has approximately a 50:50 mis slow twitch and fast twitch muscle fibers. Do you think this is true for each muscle in the body? Explain your answer.

  No, I do not think it is true for each muscle in the body. People who are more active in certain activities, may have a different slow twitch to fast twitch muscle ratio.

  For example, take a sprinter and a marathon run, both train for their respective activities and have done it for years. The sprinter must be able to run quickly and in a short time so they are more likely to have more fast-twitch muscle fibers. On the other hand, a marathon runner must be able to run at a steady pace over a long period of time so they are more likely to have more slow-twitch muscle fibers.
