Leg cramps caused by excessive exercise are mainly caused by excessive stretching of the leg muscles, tendons, and fascia during exercise, causing edema of the above cells, which will then lead to having significant leg soreness, pain, and cramps, especially when resting after exercise. This condition is mainly caused by excessive contraction of the muscles, tendons and fascia that are overstretched when resting. After this happens, you must pay more attention to keep warm and avoid getting cold. You can perform leg massage after exercise to relax the muscles, fascia and tendons of the legs, so that the blood circulation of the muscle cells of the above-mentioned tissues will increase, which will help the edema subside and the recovery of leg cramps.
