How do muscles become stronger and stronger?

The more developed the muscles, the greater the strength. We all have the impression in our minds that a very strong person does not necessarily have very strong muscle tissue. How to explain this anomaly? This is because the size of a muscle is only one of the factors that determine its strength.

The contraction strength of muscles depends on the following five factors:

1. A

A strong accumulation of a large number of motor neurons has the ability to gather as many muscle fibers as possible in an instant. This gathering ability is carried out by the nervous system as a medium.

All gatherings begin in the cerebral cortex: commands to contract muscles are communicated by the spinal nerve center. Until the motor neuron takes over the muscle fiber, each motor neuron controls a set of muscle contractions determined by the muscle fiber. The greater the number of active motor neurons, the greater the number of contracting muscle fibers. Therefore, training should be carried out with the help of heavy objects. The more weight you control, the more you can learn how to gather motor nerves.

2. The driving force sent by each motor neuron. The

motor neurons can fire to the muscle at some varying frequency. If this frequency is low, the muscle will contract and weak; on the contrary, if the motor neuron fires in a strong burst, it will Strongly stimulate and gather muscle fibers, this is the intensity of training, that is, the ability to train and develop muscles with the help of heavy objects. For the increase of nerve impulse, reinforcement exercises also play an important role.

3. Muscle volume

There is a rigorous relationship between the muscle fiber volume and the force it can generate. The larger the fibrous tissue associated with motor neurons, the greater the force generated by nerve impulses. With the aid of a load that is about 80% of your maximum strength, muscle mass can be developed through repeated exercises.

4. Intramuscular coordination

For people who often sit, when motor neurons emit a very strong driving force, they operate in a messy way between each other. Muscle fibers contract in a chaotic manner and therefore are less efficient. With exercise exercises, muscles can be more adapted to exercise discharge exercises, and then muscle fibers will begin to contract in a coordinated manner, so that the muscles can be developed. The reason for this advantage is due to the use of muscle training with a load close to his maximum strength.

5. It

is rare that only one muscle contracts at the same time. Generally, a group of muscles are activated to promote action. When resistance becomes stronger, the muscles of novice athletes cannot work together effectively. For example: when doing traction on the horizontal bar, it can be seen that novices tend to only pull up on one side, rather than in a non-stop linear manner, swinging back and forth in order to maintain body balance.

With the progress of training, the quality of sports has been improved. This is just because I learned to move the arms and back together, and the muscles on the left and right have become more coordinated.

The efficiency gained is presented in strength. When we want to learn a new movement, the situation is the same in all physical education disciplines. This is the amount of exercise. Therefore, repeated exercises or exercises can improve the coordination of muscles.

Regular muscle training makes the athletes' muscles accustomed to working together in harmony. As a result, athletes can accept and master a new movement quickly because they have done a lot of muscle training before.
