What causes calf cramps when stretching?

Leg cramps during stretching are usually related to sudden muscle tension or overextension. This may occur because, during a stretch, the calf muscles rapidly extend within a short period of time, causing excessive contraction of muscle fibers and triggering cramps. Additionally, if the body lacks essential nutrients such as calcium and potassium, muscle excitability increases, making cramps more likely during activities like stretching. To prevent this condition, it is recommended to engage in regular physical exercise to improve muscle strength and flexibility, while also ensuring adequate intake of key nutrients like calcium and potassium. If cramping occurs frequently or progressively worsens, prompt medical evaluation is advised to rule out underlying health issues.
