Jeanette is planning to take part in a charity bicycle race. Describe what types of muscle fibers she will need to use at the beginning of the race as opposed to several miles into the race and why.
What will be an ideal response?
Jeanette will start out the race by using her slow-twitch fibers as the activity is aerobic. However, once she has started to use up all of the available glucose (due to prolonged activity), her body will begin using her fast-twitch muscle fibers as they can function anaerobically.
