年龄渐增,而肌肉渐衰,这是人体老化的显著表现之一,在医学上被称为“少肌症”。一般来讲,50岁后,肌肉力量每年约下降1.5%,60岁后每年下降3%。国外研究发现,在60~70岁的年龄段中,少肌症的发病率占15%,70~80岁占20%~30%,而80岁以上高达50%。北京、上海等地进行的研究也发现,我国的情况与国外的数据基本相似。老人常会感觉没劲,皮肤干燥瘙痒、皱褶增多。其实,这些都是肌肉减少的表现。因此,肌肉锻炼是必不可少的锻炼项目。通过一些锻炼延缓肌肉衰退,力量型运动就是极为重要 Increasing age, and muscle decline, which is a significant manifestation of human aging, medically known as “sphincter ”.

Foreign study found that in the age group of 60 to 70 years, the incidence of sarcopenia accounted for 15%, 70 to 80 years accounted for 20% to 30%, while 80 years of age up to 50%. Research conducted in Beijing, Shanghai and other places also found that the situation in our country is basically similar to that of foreign countries.
