What causes leg weakness and trembling after exercise?
Generally, after exercise or other strenuous activities, weakness and trembling in the legs may result from muscle fatigue, hypoxia (oxygen deficiency), muscle strain, and other causes. A detailed analysis is as follows:
1. Muscle Fatigue
After prolonged or intense physical activity, muscles can become fatigued, leading to feelings of weakness and trembling in the legs. It is important to rest appropriately after exercise to allow the body sufficient time to recover.
2. Hypoxia (Oxygen Deficiency)
During exercise, the body requires increased oxygen supply. If oxygen delivery is insufficient, muscles may become hypoxic, resulting in weakness and tremors. Symptoms usually gradually improve with rest. Since dehydration is common during physical activity, it is important to replenish fluids promptly.
3. Muscle Strain
Incorrect posture during exercise or inadequate warm-up beforehand may lead to muscle strain, causing leg weakness and shaking. Gentle massage may help relieve discomfort associated with muscle strain.
In addition, low blood sugar (hypoglycemia) can also cause these symptoms. It is recommended to seek medical evaluation at a hospital to determine the underlying cause and receive appropriate treatment. Getting adequate rest in daily life can also help alleviate symptoms.
