The difference between muscle strength and muscle tone

For friends who do physical exercise, what they are most concerned about is their muscle strength, because the purpose of exercise is to strengthen the body, and good muscle strength is the best evidence to prove the effect of their own exercise. In terms of muscle strength and muscle tension, many friends are still not able to distinguish well. In order to help everyone understand the difference between the two and establish a better understanding, the following article we are going to talk about the difference between muscle strength and muscle tension!

Muscle strength

Muscle strength refers to the force of muscle contraction, which is the ability of the human body or a part of the body's muscles to overcome internal and external resistance when working (contracting or stretching).

Paralysis of different parts or combinations can be named as follows: ① Monoplegia: paralysis of a single limb, more common in poliomyelitis; ② Hemiplegia: paralysis of one limb (upper or lower limb paralysis) often accompanied by unilateral cranial nerve damage, more common in intracranial damage or stroke; ③ Crossed hemiplegia: paralysis of one limb and contralateral cranial nerve damage, more common in brainstem lesions; ④ Paraplegia: paralysis of both lower limbs, the result of transverse spinal cord injury, more common in spinal cord trauma and inflammation.

Muscle tone

The tension of a muscle when it is at rest and relaxed is called muscle tone. Muscle tone is the basis for maintaining various postures and normal movements of the body, and manifests itself in many forms. To put it simply, when muscle tension is high, the limbs become stiff and tight, and even like a stick. When muscle tone is low, the limbs are loose and you may feel no resistance during the examination.

The generation and maintenance of muscle tone is a complex reflex activity, and its reflex arc is called the "r-loop", which includes the afferent part of the r-loop (the receptors of the muscle tone reflex are the muscle spindles and tendon spindles) and the efferent part of the r-loop (the a motor neurons in the anterior horn cells of the spinal cord and the motor nuclei of the brainstem control the extrafusal muscles, and the r motor neurons send out Ar fibers to reach and control the intrafusal muscles). Lesions in any part of the reflex arc can cause changes in muscle tone.

I believe that after reading this article, everyone has a basic understanding of muscle strength and muscle tension. The key to disease treatment is to treat it as early as possible, so once you find that there is a problem with your health, you must go to the hospital for examination and treatment as soon as possible!
