To begin with, exercises that move your body rather than the weight (such as the push - up) have been shown to
fire more muscle fibers than exercises that move the weight rather than your body (such as the bench press).
Also, since your body is moving through space rather than the weight moving, you actually
fire more muscle fibers.
This is because your body compensates for the instability by
firing more muscle fibers in order to stabilize the resistance.
Not exact matches
So, the most powerful
muscle fibers fire first instead of the ones
more useful for endurance.
Also we have lot dormant
muscle fiber which starts
firing if you go for
more repetition.
... but when it comes to optimizing your brain and nervous system, recruiting
muscle fibers, enhancing nerve
firing speed, and optimizing brain - body coordination, it is far
more important to instead focus on fast, explosive movements — whether you're a weekend warrior or a professional athlete.
Through overspeed training, not only do your neurons literally learn how to
fire faster and control your
muscles more efficiently at higher speeds, but you also develop
more powerful and quick
muscle fiber contractions, which, as you've already learned, is crucial for performance, function and longevity.
Speed training teaches your brain to
fire faster and control your
muscles more efficiently at higher speeds and also develops quicker and
more powerful
muscle -
fiber contractions.
Your body adapts by activating
more fibers in the
muscles involved in a certain movement (meaning your nervous system adapted by
firing signals to
more muscle cells).
The kind of explosive movements you can do with a medicine ball
fire up your central nervous system, prepping it to recruit
more muscle fibers when you perform subsequent exercises.
All this intense stabilizing work
fires many
more muscle fibers than are normally required for a push - up, resulting in a tremendously effective exercise for the chest.
