Exercise for a long time. Large amount of exercise, sweating, and no timely salt supplement. A large amount of liquid and electrolyte are lost in the body. Accumulation of metabolic waste. The blood circulation of muscle is not good, and it is easy to have spasm.

During strenuous exercise. The whole body is tense and the leg muscles contract too fast. The relaxation time is too short, the local metabolism product lactic acid increases, the muscle contraction and the relaxation are difficult to coordinate, thus causes the crus muscle spasm.
Why is the cramp? 5. Poor sleeping posture
For example, if you lie on your back for a long time, make the quilt press on the foot, or lie on your face for a long time, make the foot rest on the bed, force some muscles of the calf to be in an absolute state of relaxation for a long time, and cause 'passive contracture' of muscles.
