In fact, this is because our muscles get a little tired. Because usually when you suddenly carry a weight The muscles don’t tremble, they tremble after a while.

Agree Why do our muscles tremble when they are stressed?
muscle movements, This happens thanks to nerve signals coming from the spinal cord. Nerve cells connected to many muscle cells are known as motor units.
Size of motor units, It is proportional to the force required to move the muscle. For example, motor units in the arms and legs; It allows each nerve to control about 1500-2000 muscle cells.
Some As motor units expand Some are also narrow. This irregular movement actually ensures that the muscles work properly and in a coordinated manner. However, when muscle fatigue occurs, some motor units must rest. This situation causes the remaining units to be more heavily loaded, which causes imbalances. This imbalance manifests as tremors when the motor units start working again.
muscle fatigue There are generally two reasons: nutrition and neural factors. Nerves must work at the frequency and force required to transmit signals to the muscles. In order for the nerves to meet these high demands during exercise, regular training is necessary. If this is not enough, the nerves may not be able to transmit high-frequency signals; this can cause the motor units to become unbalanced.
Water and electrolytes are used extensively during muscle movements. If these are not quickly restored, this will have a negative effect on signal transmission. motor units not working can also be the result. This situation manifests itself again as vibrations.
These situations your muscle capacity has reached its limit Although it is visible, it is usually temporary. In simple terms, tremors are a signal that your muscles actually need rest.
