Incidentally, as well as being a useful survival tool, sprinting helps improve your muscle tone, increases anabolic hormone concentrations, lower your body fat levels, improve your aerobic and anaerobic fitness and targets your type 2b fast -
twitch muscle fibers so as well being a life skill, you'll look and feel better too.
Not exact matches
Consider that 80 % of the
muscle fibers in the soleus are slow -
twitch and have a slow contraction velocity and low tension capacity
so it's not the brightest idea to go heavy when training them.
When you exercise with heavy weight and low reps, you are working on all of your
muscle fibers, both the quick and the slow
twitch fibers,
so use really heavy weight that you can only lift a low number of times.
So what does all of this fast
twitch, slow
twitch muscle fibers have to do with improving your strength?
Lifting weights quickly utilizes the fast -
twitch muscle fibers,
so if you want to build more
muscle and get stronger, lifting faster is the way to go.
Unfortunately, slow
twitch muscle fibers are limited in their potential for growth
so even if a
muscle group is primarily slow
twitch, you should definitely include some lower rep training to maximize the fast
twitch fibers you've got in that
muscle.
One of two surefire ways to increase the recruitment of fast -
twitch muscle fiber is fatigue,
so consider it your friend.
This system will be another way to overload your
muscles, as you will be firing those
muscle fibers so fast, you are going to recruit the fast
twitch fibers and evidently you're going to cause
muscle damage (a good thing).
