与年龄相关的肌肉质量和功能损失代表了个人和社会经济方面的挑战。本研究的目的是确定与非训练对照组（CON）相比，进行12周高强度阻力训练（3次/周）（HRT）的高龄个体（83岁以上）骨骼肌组织的适应性。两组都补充了相似的蛋白质。我们研究了26名参与者(每个方案86.9±3.2 （SD)（83-94，范围）岁）。股四头肌横截面积（CSA）组间差异显著（P< 0.05），仅HRT组增加1.5±0.7 cm(2) (3.4%) （P< 0.05）。CSA升高与CSA基线水平呈负相关(R-2 = 0.43， P
Age-related loss of muscle mass and function represents personal and socioeconomic challenges. The purpose of this study was to determine the adaptation of skeletal musculature in very old individuals (83 + years) performing 12 weeks of heavy resistance training (3 x/week) (HRT) compared to a non-training control group (CON). Both groups received similar protein supplementations. We studied 26 participants (86.9 +/- 3.2 (SD) (83-94, range) years old) per-protocol. Quadriceps cross-sectional area (CSA) differed between groups at posttest (P< 0.05) and increased 1.5 +/- 0.7 cm(2) (3.4%) (P< 0.05) in HRT only. The increase in CSA is correlated inversely with the baseline level of CSA (R-2 = 0.43, P
