耐力训练和增加蛋白质摄入量改善了慢性肺病 (CLD) 患者的肌肉力量和身体组成. 对于这个弱势群体来说,低力度干预是可行的.
科学领域:
- 运动生理学 运动生理学
- 临床营养学 临床营养学
- 肺部康复治疗 肺部康复治疗
背景情况:
- 在慢性肺病 (CLD) 中,肌肉衰竭和肌肉衰弱很普遍,会损害身体功能.
- 虽然抵抗训练和蛋白质摄入对健康成年人有好处,但它们对CLD患者的影响还未得到充分研究.
研究的目的:
- 为了研究联合抵抗训练和增加蛋白质摄入量对CLD患者肌肉力量和身体组成的影响.
- 评估低努力,现实生活干预措施的可行性,以改善这一群体的结果.
主要方法:
- 一项前性,非随机对照性研究,涉及16名CLD患者 (51-85岁).
- 三个为期六周的干预阶段:通常的饮食,建议的蛋白质摄入量 (1.2-1.5 g/kg) 和训练后的蛋白质补充.
- 综合力量和耐力训练在整个过程中进行,结果包括最大力量,身体脂肪,身体能力和生活质量 (QoL).
主要成果:
- 蛋白质摄入量显著增加,但仍低于推水平.
- 最大强度显示边际显著增加 (4.6公斤).
- 尽管训练强度低,蛋白质摄入量低于最佳水平,但观察到显著的体脂减少,体重没有变化.
结论:
- 针对性抵抗训练和增加蛋白质摄入量为CLD患者的力量和身体组成带来了可衡量的改善.
- 在这个脆弱群体中,低功耗干预措施是改善强度和蛋白质消耗的实用方法.
