[cramps]
many people feel that leg cramps are because of calcium deficiency, calcium can be treated. In fact, cramps are caused by various causes during sleep, not just because of calcium deficiency.
(1) sleeping under cold
exercise in a cold environment. Not enough preparation activities, or low temperature in summer swimming water, can easily cause leg cramps. Sleeping at night did not cover the quilt. The muscles of the calf were stimulated by cold.
(2) muscle contraction too fast
intense exercise. The whole body is in tension, the leg muscles shrink too fast, the relaxation time is too short, the local metabolic product lactic acid increases, the muscle contraction and relaxation are difficult to coordinate, thus causing the calf muscle spasm.
(3) the metabolic problem
when the exercise time is long, and the amount of sweat is large, and the salt is not supplemented in time, the liquid and electrolyte in the body are lost in a large amount, resulting in the accumulation of metabolic waste. The blood circulation of the muscle is not good, so it is easy to have spasm.
excessive fatigue
climbing and climbing, the calf muscles are most prone to fatigue. Because it is a foot that supports the weight of the body, the leg muscles need six times the weight of the foot, and when it is tired to a certain extent, spasms will occur.
calcium deficiency
calcium plays an important role in muscle contraction. When the concentration of calcium in the blood is too low, the muscles are easily excited and spasmodic. The growth of young people is rapid and easy to calcium deficiency, so leg cramps often occur.
poor sleep position is not good
if long supine, make the quilt pressed on the foot, or long prone, make the foot face in the bed, force the leg some muscle for a long time in the absolute relaxation state, cause the muscle "passive contracture".
