关于锻炼后肌肉酸痛 继续锻炼

  肌肉痛了,是不是在长肌肉?其实对于很多人来说,并不懂得健身的知识,很多人都认为肌肉酸痛是在长肌肉,这是绝对错误的。
  首先了解一下为什么剧烈运动后会肌肉酸痛。
  平时不经常锻炼的人,参加比较剧烈的运动以后,局部肌肉有时产生酸痛现象,产生这种现象的原因,通常认为与肌肉内部的能量代谢有关系。
   我们知道,肌肉的收缩需要能量;而能量是靠肌肉组织中肌糖元的分解来提供的。在氧供应充足的情况下,如肌肉在静息状态时,肌糖元可以经过丙酮酸直接分解 为二氧化碳和水,并释放能量。但是当人进行剧烈运动时,肌糖元分解加快,耗氧量增加,使肌肉暂时处于相对缺氧状态,此时肌糖元可以经过丙酮酸转化为乳酸积 存于肌肉内。乳酸在肌肉内大量堆积,会刺激肌肉中的化学感受器产生兴奋,兴奋传至大脑皮层,使人产生酸痛的感觉。同时,由于乳酸等物质的积聚,使肌肉内的 渗透压增大,促使肌肉组织内吸收较多的水分而产生局部肿胀,也会产生酸胀的感觉。引起肌肉缺氧的另一种解释是运动的肌肉疲劳时,由于局部肌纤维放松不充分 而产生轻微痉挛,使肌肉内的血管受到压迫,血流受阻,引起肌肉缺血缺氧,此时,肌肉发硬并且有酸痛的感觉。
  这个证明你的锻炼起了效果,相反如果你是一个刚踏入健身行列的人,刚锻炼了几天,如果肌肉不酸痛的话就证明你的锻炼是三心二意的,没有认真。
   肌肉疼痛很正常,但是要确保锻炼量适量,如果过量导致肌肉拉伤的话,那就不正常了,呵呵!肌肉酸痛后坚持锻炼,克服疼痛,一般4天左右就会消失,这样你 会发现你的体质有了明显的适应性增强。(如果已有酸痛感觉,也不必终止运动,可以适当减少一些运动量,同时在运动后进行局部热敷或洗热水澡等,以促进血液 循环,使肌肉酸痛得到解除。)肌肉酸痛感消失后,可逐渐增加运动量,要坚持长期参加体育健身锻炼,这样使心肺功能逐步得到提高,氧的供应量充足了,乳酸能 及时处理掉,肌肉酸痛的现象就不易产生了。
  根据我的经验和健身前辈的资料,一般要想生长肌肉,必须保证每个部位一个星期锻炼2次且3个月后肌肉才能增长。要想有强壮的体魄不是一两天就能练就的,如果这样那么这个世界上有不会再有瘦弱的人了。
  请大家记住,贵在坚持!
