摘要

摘要目的采用不同系列的线性混合模型，研究老年人阻力训练(RT)后肌力增强对功能能力(FC)改善的影响。方法:11名健康老年人进行了为期12周的非线性分期腿部按压RT计划。在大鼠运动前后测量单次最大腿推(1-RM)、股四头肌和腘绳肌同心(Qcon和Hcon)和偏心峰值扭矩(PT)，以及FC测试(30-s，计时和go [TUG]，楼梯上升和下降)。1-RM每变化1个单位，30-s变化3.38个单位，TUG变化- 0.67个单位，楼梯上升变化- 0.93个单位，楼梯下降变化- 0.75个单位，Qcon和Hcon PT每变化1个单位，楼梯上升变化- 0.46个单位，- 0.84个单位(p < 0.005)。结论:我们的详细分析提供了证据，证明力量特异性增益对老年人RT后运动特异性FC改善有积极影响。

Influence of Muscle Strength Gains on Functional Capacity Improvements following Resistance Training in Older Adults: A Linear Mixed Model Approach

Abstract Aims By using different series of linear mixed models we investigated the influence of muscle strength gains on functional capacity (FC) improvements in older adults following resistance training (RT). Methods: Eleven healthy older adults performed a 12-week non-linear periodization leg press RT program. Leg press one-repetition maximum (1-RM), quadriceps and hamstrings concentric (Qcon and Hcon) and eccentric peak torque (PT), and FC tests (30-s, timed-up and go [TUG], stair ascent and descent) were measured before and after RT. Results: Every one-unit change in 1-RM led to 3.38 unit change in 30-s, −0.67 unit change in TUG, −0.93 unit change in stair ascent and −0.75 unit change in stair descent, and every one-unit change in Qcon and Hcon PT led to −0.46 and −0.84 unit changes in stair ascent (p < 0.005). Conclusions: Our detailed analyses provide evidence that strength-specific gains positively influence movement-specific FC improvements in older adults following RT.

期刊介绍： This comprehensive journal is recognized for its useful balance of research and clinical practice articles. For more than twenty five years Physical & Occupational Therapy in Geriatrics has functioned as a forum for allied health professionals as well as others with a focus on rehabilitation of the geriatric client to share information, clinical experience, research, and therapeutic practice. Each issue focuses on current practice and emerging issues in the care of the older client, including rehabilitation and long-term care in institutional and community settings, and innovative programming; the entire range of problems experienced by the elderly; and the current skills needed for working with older clients.
