2015-05-24 MedSci MedSci原创

目的:该实验的目的是向肌无力的老年人发出号召和建议,鼓励他们采用渐进抗阻练习法,从而增加他们的瘦体重、肌纤维尺寸、肌力和身体功能。方式:该研究为回顾性研究,将年龄大于65岁的老年人分为两组,一组人数为110人,采用渐进抗阻训练法训练时间为12周;另一组有85人,采用渐进抗阻练习法训练时间为24周。我们在训练前、训练12周后、训练24周后分别检测参与人员的瘦体重(采用DXA即骨密度仪)、I型和II型

目的:


该实验的目的是向肌无力的老年人发出号召和建议,鼓励他们采用渐进抗阻练习法,从而增加他们的瘦体重、肌纤维尺寸、肌力和身体功能。

方式:

该研究为回顾性研究,将年龄大于65岁的老年人分为两组,一组人数为110人,采用渐进抗阻训练法训练时间为12周;另一组有85人,采用渐进抗阻练习法训练时间为24周。我们在训练前、训练12周后、训练24周后分别检测参与人员的瘦体重(采用DXA即骨密度仪)、I型和II型肌纤维尺寸(采用活组织切片检查)、腿部力量(1-RM的腿部推举和背伸)、身体功能(利用参与人员把椅子举到某一高度所用时间)。

结果:

实验表明,经过12周渐进抗阻训练的老人,瘦体重增加0.9±0.1 kg(范围为−3.3到+5.4 kg; P <0.001);I型和II型肌纤维尺寸分别增加324±137μm2 (范围为−4458 到+3386μm2; P= 0.021)和701±137μm2(范围为−4041到+3904μm2; P<0.001);1-RM的腿部推举和背伸力量分别增加33±2 kg(范围为−36 到+87 kg; P<0.001)和 20±1 kg (范围为: −22 到 +56 kg; P <0.001);举椅时间减少1.3 ± 0.4秒(范围为: +21.6到−12.5 s; P=0.003)。

经过24周渐进抗阻训练的老人,瘦体重增加 1.1±0.2 kg(范围为−1.8到+9.2 kg; P<0.001);I型和II型肌纤维尺寸分别增加360 ± 157μm2 和779±161μm2 (范围为−3531到+3426μm2; P=0.026和−2728到+3815μm2; P<0.001).)和 −4041到+3904μm2; P<0.001);1-RM的腿部推举和背伸力量分别增加50±3 kg (范围为:−28到+145 kg; P <0 .001) 和29±2 kg (范围为:−19到+60 kg; P<0.001);举椅时间减少2.3±0.4秒(范围为: +10.5 到−23.0 s; P<0.001)。参与人员肌无力的表现并不明显,经过一次渐进抗阻练习法都会使肌肉收缩表现明显。

结论:

老人经过渐进抗阻练习法后,他们的瘦体重、肌纤维尺寸、肌力和身体功能出现适应性的变化有很大的个体差异。且肌力和反应性与渐进抗阻训练法的持续时间有关,持续时间越长,肌力和肌肉反应性越好。

通过渐进抗阻训练法,可以增加老人的瘦体重、肌纤维尺寸、肌力和身体功能,提高肌肉反应性。因此,渐进抗阻训练法适用于老年人,应在老人身上得以普及,以提高老人的机体功能。
