Muscle proteins are not degraded by some types of workout, so there is no mechanism of overcompensation that aims to hypertrophy the muscle. Once UM’s innervation is optimized, the body will seek to increase the level of strength of each muscle fiber. The strength potential of a muscle depends on its cross-section, that is, its size: the bigger the muscle, the stronger it is.
This hypertrophy is a response of adaptation of the muscles to the stress that is submitted to them. During intensive resistance training, the muscles ache and suffer from microlesions. To no longer have to suffer this pain in anticipation of future training, the muscle will seek to adapt: it will strengthen and therefore grow. This is the principle of overcompensation.
The potential for muscle hypertrophy is genetic because it is strongly related to muscle composition, with fiber two having the greatest potential for growth. Several components of muscle can get fat after training, and therefore contribute to increase the size of the whole muscle.
The training stimulates the increase of the synthesis of the contractile proteins (actin and myosin filaments), which has the effect of increasing the size of the myofibrils, then of multiplying them. It follows a thickening of the muscle fibers, and therefore of the entire muscle benefits from Culture Starters Australia.
The hypertrophy gives the muscle a greater potential for contraction. It builds muscle tissue itself, and therefore increases the maximum strength. To adapt to this new potential, the connective tissue will also have to strengthen and thicken, which will also help to make the muscle grow.
Resistance training (medium) leads to an increase in glycogen stores in the muscle. The muscle fiber is more filled with glycogen, so it is gaining volume. In addition, 1g of glycogen retains nearly 3g of water, so the volume of the sarcoplasmic fluid will increase, again contributing to volume of the muscle.
The increase in glycogen stores is the main mechanism of sarcoplasmic hypertrophy. It can occur in all types of muscle fibers, but the fibers 2 have larger reserves and therefore greater potential thanks to Culture Starters Australia.
Endurance training (long series) leads to a lower increase in glycogen reserves, but increases the concentration of myoglobin and the number and size of mitochondria, which can also increase the volume of sarcoplasmic fluid, and therefore to the muscle. In the same way, it allows to develop new blood capillaries which will also increase the size of the muscle.
This mechanism occurs mostly in slow fibers that are oxidative. After a session of bodybuilding in long series, the muscles are often inflated because of the blood flow. This phenomenon is a temporary increase in volume, and fades a few hours after training.
