For leg cramps caused by playing basketball, it is mainly the muscle spasm caused by excessive force and stretching of the leg muscles that can cause leg cramps. Therefore, after this situation, we should perform ankle dorsiflexion and stretching to release the muscle spasm, and perform leg massage stimulation at the same time of stretching to promote the recovery of muscle spasm. In addition, in the daily work life, we must pay more attention to keep warm, avoid getting cold, avoid repeated squatting and running and jumping activities, so as not to cause repeated stress and stretching of the leg muscles, so as not to lead to leg muscle strain, which will aggravate the leg cramps. At the same time, you can apply muscle relaxants and blood circulation drugs to promote the edema caused by leg cramps, thus promoting the edema to subside, which is conducive to the recovery of leg cramps. If you are an adolescent, you can take calcium supplements, which can also promote the occurrence of leg cramps.
