Twitching is the performance of involuntary movement, twitching after exercise may be a local muscle spasm, but also may be the whole body muscle twitching, and not warmed up before exercise, excessive exercise and cold stimulation, calcium deficiency, etc. 1, not warmed up before exercise: if not fully warmed up before exercise, sudden strenuous exercise will lead to local muscle spasm, so pay attention to good stretching and other warm-up exercises before doing exercise; 2. Excessive exercise: when strenuous exercise, the body will sweat a lot, when the body’s electrolyte balance is affected, it will lead to increased muscle excitability and local muscle twitching; strenuous exercise, easily lead to the accumulation of lactic acid in the body, the secretion of inflammatory substances, will also lead to muscle soreness and twitching. Therefore, daily should try to avoid strenuous exercise, exercise should pay attention to replenish electrolyte solution, after exercise should pay attention to stretching and relaxation; 3, cold stimulation: when the weather temperature is relatively low, vascular contraction easily induced muscle twitching, general winter sports out recommend good warmth measures to prevent cramps; 4, calcium deficiency: calcium deficiency will make the nerve, muscle excitability increased, thus causing muscle spasm twitching phenomenon. Usually pay attention to calcium intake, eat more calcium-rich food, such as milk, tofu, shrimp, etc., or you can directly use calcium tablets for calcium; 5, epilepsy: if there is a generalized convulsion, you need to be alert to the possibility of seizures, then you need to immediately consult a doctor, do an electroencephalogram examination to clarify the diagnosis, and if there is indeed epilepsy, you need to use drugs to control epilepsy under the guidance of a doctor.
