Genes Influence Ability To Build Muscle
Who can measure his genetical potential for building muscle is
more realistic about his training and can be saved from big disappointments that often
let people quit their workouts soon. But genetics should not be misused to explain poor
results that came from poor will...

Hormones
Women basically don't have the possibility of building as much muscle
mass as men, primarily because of their different hormone situation. Even for men there are
individual and age related differences in testosterone production. These hormones
play a central role in the anabolic (building) metabolism. There are ways to influence
hormones naturally, but most amateur and pro bodybuilders prefer the easy way of drug misuse.
If you feel attracted by steroids, please first read about natural and unnatural bodybuilding
before doing the wrong thing.
Muscle length
The length of a muscle bulge in relation to it's tendons is determined and limits directly
the extend of a muscle's possible thickness. Why is this so?
Untrained muscles only have their
deepest (innermost) fibers thickened respectively in an active state, since they have the
best efficiency: their force vector affects direct, even way. The remaining fibers can be
called reserve fibers and are mostly inactive. When you start your workouts, you and your body
soon realize that you are too weak to handle a weight and you try to go further than
your muscles actually can. Thats where your brain sends out strong nervous stimuli to
the muscle and thus activates unused, outer fibers. Through this activation they get
thickened in the workout's following regeneration process and are ready to help in the next
workout.
The outermost fibers have the worst physical efficiency. A part of their tension
only increases pressure and thus friction in the muscle inside - in extreme cases
these fibers would harm more than help. That is the reason why a certain relation
of muscle length to muscle height cannot be exceeded.
Fiber count
The number of fibers a muscle has is genetically determined and unchangeable like
the number of nerve cells in the body. The more fibers, the better your bodybuilding
potential
Type of fiber
There are two types of fibers in the muscle, which proportion is genetically
determined, following the current state of research. This proportion can vary
from muscle to muscle in the body and from person to person.
Slow twitch
Slow twitch fibers develop less tension and contract slower, but are persistent
in performance say for aerobic activity. Slow twitch dominant people are good
long distance runners, however they never are good sprinters
(there is no transformation from slow twitch to fast twitch fibers). They normally
have fewer back problems and the like. The ability to build huge muscle mass is limited
- higher repetition numbers are recommended (longer set duration respectively).
Fast twitch
Fast twitch fibers have more strength and contract faster, but are faster exhausted.
Slow twitch dominant people rather are good sprinters, but can also be good endurence
athletes, since these fibers can change themselves temporarily to slow twitch fibers.
The ability to train for muscle mass is good - deeper repetition numbers are
recommended.
Bone structure
Bone structure surely doesn't have an influence on your muscle's training abilities,
but it substantially influences the appearance and can bring crucial advantages to a
bodybuilder standing on stage.
