twitch muscle fibers

muscles consist of slow -
twitch (Type I)
muscle fibers and can sustain force and contraction
for an extended period of time.

For example, if your main goal is to get bigger, doing some speed and maximal strength work can help to increase the size of your fast -
twitch muscle fibers and, therefore, help you to gain overall
muscle size!
Training at this intensity primarily uses slow -
twitch muscle fibers, since these
fibers provide more most of the mobility
for events lasting 2 minutes or longer, workouts at this intensity should comprise most of your training.Training above this intensity will not significantly overload your slow -
twitch fibers, which you are attempting to train to become more efficient at using fat and oxygen to produce energy while conserving carbohydrate stores.
As
for your
muscle physiology, the relative proportion of fast
twitch and slow
