卷腹

卷腹(英語:curl-up[1]又称屈腹[註 1][2](crunch)[3],是受欢迎的腹部运动之一。如果操作得当,它能调动所有的腹部肌肉,但它主要鍛鍊腹直肌斜方肌。它既可以塑造腹肌,又可以收紧腹部。卷腹利用锻炼者自身的体重来锻炼肌肉,被推荐为一种可以在家里进行的低成本运动。

形式

在卷腹时,腰部没有抬离地面

纽约时报健康博客引用生物力学教授Stuart McGill的话说:

认可的卷腹开始时,你要躺下,单膝弯曲,双手置于下背部下方以提供支撑。麦吉尔说:"不要凹陷你的腹部或将你的背部压在地板上"。轻轻地抬起你的头和肩膀,短暂地保持,然后放松下来。[4]

在卷腹时,与仰卧起坐不同,下背部保持在地板上。据说这可以消除臀部屈肌的任何参与,并使卷腹动作成为腹部的有效隔离练习。[5]

變種

卷腹的動作有數個變化:

  • 平地卷腹,平躺於地上,雙膝彎曲,腳平放在地面上。
  • 抬腿卷腹,平躺於地上,雙腿彎曲抬起懸空,小腿與地面平行。
  • 低抬腿卷腹,與抬腿卷腹動作一樣,但腿部向下放,仍保持騰空,離地面幾寸距離。[6]

备注

  1. ^ “屈”作动词,意为使弯曲,与“伸”相对。同类用词有:低头屈膝、屈指一算等。
