一、肌肉痉挛产生的原因 ①寒冷刺激 如冬天在寒冷的环境中锻炼准备活动不充分;夏天游泳水温较低,都容易引起腿抽筋晚上睡觉没盖好被子,小腿肌肉受寒冷刺激会痉挛得让人疼醒②肌肉连续收缩过快 剧烈运动的时候,全身都处于紧张的状态,腿部肌肉收缩比较的快放松的时间特别的短,代谢产物乳酸增加,肌肉的收缩与放松很难协调好,导致小腿肌肉痉挛的出现③出汗过多 运动时间长运动量大,出汗多,又没有及时补充盐分体内液体和电解质大量丢失代谢废物堆积肌肉局部的血液循环不好,也容易发生痉挛④疲劳过度 当长途旅行、山、登高时,小腿肌肉最容易发生疲劳因为每一次登高人的全部重力都在一只脚上,这条腿的肌肉提起脚需要的力量是人体重的六倍,当它疲劳到一定程度的时候,就会发生腿抽筋
