背景本研究的目的是确定10周的阻力（RT），功能（FT），或功能加阻力（FRT）训练的老年人谁修改日常生活的任务，并在随后的残疾风险的有效性。32名老年人（75.8 +/- 6.7岁）在控制期和训练后进行了测试。该研究的主要结果是任务修改的数量和日常生活中八项任务的定时性能。次要结果包括膝关节和肘关节力量（伸展和屈曲）、身体成分、自我报告的身体功能、单腿平衡时间、步行速度和吸尘地毯的时间。RT组进行渐进强度训练，FT组每周进行2天任务特定训练。FRT组每种训练类型进行1 d。对照期内无变化。所有三个训练组都减少了修改日常生活任务的需要（RT：21%，FRT：26%和FT：28%），并改善了自我评价的功能和吸尘地毯的时间。每周进行1天或2天FT的个体也降低了他们的时间表现（RT：2.5% [p = 0.48]，FRT：18.5%，FT：23%）。力量增加主要见于每周进行1天或2天RT（RT和FRT）的组。步行速度，单腿平衡，或身体composition.Conclusion：运动的好处是依赖于训练过程中执行的任务没有发生显着变化。对低功能老年人的锻炼建议应反映特定任务的锻炼，以防止残疾的发生。
Background. The purpose of this study was to determine the efficacy of 10 weeks of resistance (RT), functional (FT), or functional plus resistance (FRT) training in older adults who modify tasks of everyday life and are at risk for subsequent disability.Methods. Thirty-two older adults (75.8 +/- 6.7 years) were tested following a control period and training. The primary outcome of the study was the number of task modifications and timed performance on eight tasks of daily life. Secondary outcomes included knee and elbow strength (extension and flexion), body composition, self-reported physical function, single-leg balance time, walking speed, and time to vacuum a carpet. The RT group performed progressive intensity training, and the FT group performed task-specific exercises 2 days per week. The FRT group performed 1 day of each training type.Results. No changes occurred in the control period. All three training groups reduced the need to modify tasks of everyday life (RT: 21%, FRT: 26%, and FT: 28%) and improved self-rated function and time to vacuum a carpet. Individuals who performed FT either 1 or 2 days per week also reduced their timed performance (RT: 2.5% [p = 0.48], FRT: 18.5%, and FT: 23%). Strength gains were primarily found in groups that performed RT either 1 or 2 days per week (RT and FRT). No significant changes occurred in walking speed, single-leg balance, or body composition.Conclusion: The benefits of exercise are dependent on tasks performed during training. Exercise recommendations for low-functioning older adults should reflect task-specific exercise to prevent the onset of disability.
