This study aimed to evaluate the effects of exercise cognitive combined training (ECCT) compared with non-ECCT on physical function in cognitively healthy older adults. Databases were searched for randomized controlled trials from inception to December 2, 2021, and 22 studies (1,091 participants, Mage = 74.90) were included in the meta-review. The Cochrane Risk of Bias and Grading of Recommendations Assessment, Development, and Evaluation tools were used for quality assessments. ECCT improved gait speed (mean difference: 0.06 m/s, 95% CI [confidence interval] [0.02, 0.11]; 446 participants, 11 studies) and balance (standardized mean difference: 0.38, 95% CI [0.14, 0.61]; 292 participants, seven studies). Simultaneous ECCT, but not nonsimultaneous ECCT, improved gait speed (mean difference: 0.11 m/s, 95% CI [0.07, 0.15]), balance (standardized mean difference: 0.40, 95% CI [0.16, 0.64]), and functional mobility (mean difference: -0.85 s, 95% CI [-1.63, -0.07]; 327 participants, nine studies). Future research should focus on the duration and form of ECCT intervention optimal for improving the functional activities of older individuals.
本研究旨在评估与非运动认知联合训练（ECCT）相比，运动认知联合训练（ECCT）对认知健康的老年人身体功能的影响。检索数据库，查找从数据库建立至2021年12月2日的随机对照试验，22项研究（1091名参与者，平均年龄74.90岁）纳入了荟萃综述。采用Cochrane偏倚风险评估工具和推荐意见分级、评估、制定与评价工具进行质量评估。ECCT改善了步速（平均差值：0.06米/秒，95%置信区间[CI][0.02, 0.11]；446名参与者，11项研究）和平衡能力（标准化平均差值：0.38，95%CI[0.14, 0.61]；292名参与者，7项研究）。同步ECCT而非非同步ECCT改善了步速（平均差值：0.11米/秒，95%CI[0.07, 0.15]）、平衡能力（标准化平均差值：0.40，95%CI[0.16, 0.64]）和功能活动能力（平均差值：-0.85秒，95%CI[-1.63, -0.07]；327名参与者，9项研究）。未来的研究应聚焦于对改善老年人功能活动最适宜的ECCT干预的持续时间和形式。
