The expression of strength is given by several factors:
must primarily think that the cross-sectional area of a muscle (what generally understand how the magnitude of the same muscle) to only port 30 % of performance.
This means that we can see individuals muscularly lower, deficit but with a far superior level of strength. This is because the strength exclusively depends not only the size but especially by metabolic neural factors.
Addentrandoci in particular the muscle fiber we analyze the functional characteristic that this mainly to be able to contract and shorten, giving visually the idea of movement.
The workout against resistance causes some real structural changes at both the myofibrils but also sarcoplasmic level.
L 'myofibrillar hypertrophy is done through training with high loads and low reps who go to better stimulate protein synthesis. A hormonal level, the main hormone 'testosterone that is stimulated more with this level of intensity.
regarding the sarcoplasmic hypertrophy is due to the increase of the sarcoplasmic and structures that compose it: water, non-contractile proteins, organelles and energy reserves such as glycogen and lipids. The fiber is adapted from a structural point of view of energy and adapting to the increased muscle work request
, this comes with the mean workouts with high repetitions and low to medium loads. In this type of training, there are mechanical-dependent growth factors and growth hormone to influence muscle hypertrophy.
To conclude, we can say that in reality the aforementioned subdivision belongs to the world of theory because in practice it is difficult to obtain compartmentalized or l 'one and the other hypertrophy. A workout can foster more of a kind of hypertrophy But in any case, always include both, however in different percentages.
In any case a methodological point of view it is useful to develop both types of hypertrophy and then specialize mainly in their discipline; for example for a bodybuilder obviously play more than sarcoplasmic but also that myofibrillar. The latter will be worth much more to others atletidi strength and power.
