概括

抵抗训练改善了老年人的肌肉力量和回声强度 (EI),但不是肌肉质地. 传统的EI测量比纹理分析更好地跟踪训练后的肌肉质量变化.

科学领域:

老年学是一门学科.
运动生理学运动生理学
生物医学成像技术生物医学成像技术

背景情况:

骨肌肉回声强度 (EI) 与老年人的功能结果相关.
抵抗训练干预措施在改善肌肉质量方面产生了不一致的结果.
纹理分析通过分析像素关系为肌肉质量评估提供了一种新的方法.

研究的目的:

评估肌肉质量的第一阶段 (EI) 和第二阶段 (质地) 特征的变化.
评估下肢力量训练对老年人肌肉质量的影响.

主要方法:

12名老年人 (平均年龄70岁) 接受了为期6周的力量训练.
进行了大腿直肠 (RF) 和大腿横筋 (VL) 肌肉的超声波成像.
评估了肌肉强度 (5RM腿部延伸,MVIC) 和超声图像纹理 (GLCM分析).

主要成果:

观察到5RM腿部伸展强度和MVIC力显著改善.
长腿直肠回声强度 (EI) 在训练后显著改善.
没有检测到肌肉大小,巨大的横向EI或任何纹理特征的显著变化.

结论:

短期抵抗训练可以增强老年人的肌肉力量和直骨肌肌肉损伤.
纹理分析特征没有显示对训练引起的变化的敏感性.
传统的EI测量似乎比纹理分析更适合监测这种人群的肌肉质量适应.

Exercise and Muscle Performance

Exercise and Muscle Performance

Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
