Increases in both the age and the number of older adults in the United States will likely result in more people living with functional limitations and physical disabilities. The impact of this change in demographics will not only significantly impact older adult quality of life but may overwhelm existing health care services for this population. Resistance training with a strengthening component is currently recommended for older adults who wish to increase strength and overall health. However, muscle power has recently been found to contribute more to improvement in physical functioning than muscle strength and is becoming a focus of many resistance training studies in older adults. This review will discuss the current research supporting the implementation of traditional strength-enhancing resistance training, examine the contribution of muscle power to function, explore the rationale for implementing high velocity power training interventions, and review the recent literature on these novel power training interventions in older men and women. Recommendations for future research will be discussed.
在美国，老年人年龄的增长以及数量的增加可能会导致更多人出现功能受限和身体残疾。这种人口结构变化的影响不仅会显著影响老年人的生活质量，还可能使针对这一人群的现有医疗服务不堪重负。目前，对于希望增强力量和整体健康的老年人，建议进行包含强化成分的阻力训练。然而，最近发现肌肉力量对身体功能改善的贡献比肌肉强度更大，并且正成为许多针对老年人的阻力训练研究的重点。本综述将讨论支持实施传统增强力量阻力训练的当前研究，研究肌肉力量对功能的贡献，探讨实施高速力量训练干预措施的基本原理，并回顾最近关于这些针对老年男性和女性的新型力量训练干预措施的文献。还将讨论对未来研究的建议。
