The most important reason for this phenomenon is the fact that the brachialis
muscle has
more slow - twitch
fibers than the biceps, and therefore, has
more of a stabilizing role compared to the biceps brachii which is
meant for faster,
more explosive work.
The majority of studies seem to support the claim that the dumbbell bench press is a better option for anyone looking to increase his chest size, mainly because of the greater range of motion involved — a greater range of motion on pressing movements
means more horizontal flexion and adduction and a greater recruitment of chest
muscle fibers.
Research shows that dumbbell military press activates
more muscle fibers than its barbell counterpart, but that doesn't
mean it's necessarily superior.
With proper use, you can not only activate
more muscle fibers, you may even be able to SPLIT your
muscle fibers, making
more of them - that
means faster gains,
more easily!
Meaning that if you express more fast twitch muscle fibers, you know, like I personally do, I'm what is called a power responder, meaning that my body responds very well to strength and power - based sets to short heavy sets with high weight rather than longer sets of 12 - 20, 25 repetitions with lighter w

More fibers in the muscle means more overall potential gro
More fibers in the
muscle means more overall potential gro
more overall potential growth!
Some people have
more slow - twitch
muscle fibers,
meaning they are
more comfortable with strength and long endurance activities.
This
means that force production is greater (and
more efficient) in the eccentric phase than the concentric phase, because passive elements resist lengthening of the
muscle fibers in the eccentric phase, but not in the concentric phase.
So this is related to the heart rate in the sense that a higher intensity
means both a higher heart rate and
more activation of the aerobic (Type I)
muscle fibers.
More muscle fibers means more po
More muscle fibers means more po
more power.
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 reason Reclining on the Sun Exercise works so well is because you are incorporating the stability
muscles in your triceps which
means essentially that you are incorporating
more muscle fibers.
This
means that when you need to kick it into high gear, your body will be able to call upon
more muscle fibers to contribute to power production to get you up that hill or to that finish line, and can do so with less wasted energy.

Muscle Building Target # 2: Heavy Lifting Cycles The reason it works: muscle damage, activation of the high threshold muscle fibers (growth fibers), potentiation of the nervous system; which means when you get back to your normal bodybuilding routine you will be able to recruit more muscle fibers for the same exe

As mentioned in the previous installment, this is indeed a method by which the body can improve the relative efficiency of these
muscle fibers, as a decrease in overall area with an increase in the capillary network
means proportionately
more blood flow to each
muscle fiber.
1Some
muscle fibers drop out when they fatigue, and other
muscle fibers are recruited so force output doesn't drop off, which
means total
muscle activation over the course of a set may be the same with heavy and light loads, even if activation at any given time point is higher with heavier loads 2 It's a little
more complicated than that, if you care to dig deeper.
The reason
more mitochondria don't always
mean that you run faster (instead of longer) is because (1) you may have far
more mitochondria than necessary to process the maximum amount of oxygen your lungs can take in and your red blood cells transport at any given time, (2) regardless of how many mitochondria you have, the motor neurons connected to your aerobic
muscle fibers are smaller than those connected to your anaerobic
muscle fibers.
All of this
means that when you challenge your body to do
more WORK — for instance, by going very slowly on the eccentric portion of the movement — you get
more of your important type 2 (fast twitch)
muscle fibers involved... which
means you become
more metabolically active to burn fat... AND build greater strength.
