身体功能与认知密切相关。目前的研究评估了三种认知训练计划对5年来身体功能客观指标的影响。随机分配到处理速度（n = 702），推理（n = 694），或记忆（n = 703）训练干预的老年人进行了比较，随机分配到无接触控制条件（n = 698）。进行意向治疗（ITT）和接受治疗（随时间变化的培训次数）分析。ITT分析中无转移效应。接受治疗的模型表明，训练课程（即，更高剂量）转移到更好地维持数字符号复制和旋转360性能相对于对照组。更多的推理训练转移到更好的握力。这是第一个研究，以证明差异纵向认知训练转移效果，以三个性能为基础的身体功能的措施。未来的研究应探讨远转移效应的机制。
Physical functioning is closely associated with cognition. The current study assessed the impact of three cognitive training programs on objective measures of physical functioning across 5 years. Older adults randomized to a processing speed (n = 702), reasoning (n = 694), or memory (n = 703) training intervention were compared to those randomized to a no-contact control condition (n = 698). Intention-to-treat (ITT) and treatment-received (time-varying number of training sessions) analyses were conducted. There were no transfer effects in the ITT analyses. Treatment-received models demonstrated that training sessions (i.e., higher dosage) across all intervention arms transferred to better maintained Digit Symbol Copy and Turn 360 performance relative to the control group. More reasoning training transferred to better grip strength. This is the first study to demonstrate differential longitudinal cognitive training transfer effects to three performance-based physical functioning measures. Future research should investigate mechanisms of far-transfer effects.
