Introduction
In general, the biceps muscle not becoming firm after contraction may be caused by factors such as diet, poor sleep, excessive fatigue, cervical spondylosis, or myasthenia. In most cases, the lack of firmness in the biceps after exertion is normal; however, in a minority of cases, it may indicate an underlying medical condition. If related symptoms are present, timely medical consultation is recommended for proper diagnosis and treatment under a physician's guidance.
Under normal circumstances, the biceps muscle not feeling firm after contraction may be caused by factors such as diet, poor sleep, excessive fatigue, cervical spondylosis, or myasthenia, and targeted treatments should be adopted accordingly. Specific causes are as follows:
1. Dietary factors: An unbalanced diet, particularly insufficient intake of protein and meat, can result in less noticeable muscle growth after exercise. It is recommended to improve dietary habits by consuming more protein-rich foods such as beef, chicken, and eggs.
2. Poor sleep: Inadequate sleep can lead to poor mental condition the following day, which may contribute to the aforementioned issue. It is advised to maintain regular sleep patterns—going to bed early and waking up early—and engage in moderate physical activity.
3. Excessive fatigue: Overexertion in daily life can cause muscle strain, resulting in soreness and weakness when lifting the arm. Symptoms usually subside after a period of rest.
4. Cervical spondylosis: In some patients with cervical spondylosis, damage to the cervical spinal canal or spinal cord may compress the central nerves that control the biceps, leading to the symptoms described. Patients are advised to undergo treatments such as acupuncture or massage under medical supervision.
5. Myasthenia: Muscle weakness caused by trauma or other conditions may manifest as localized muscle weakness; in severe cases, generalized muscle weakness may occur. Patients are advised to receive plasma exchange therapy under a doctor's guidance, along with anticholinesterase medications.
In most cases, the biceps not feeling firm after contraction is a normal phenomenon; only in rare instances is it due to an underlying medical condition. If related symptoms persist, timely medical consultation is recommended for proper diagnosis and treatment under professional guidance.
