Key result
Exercise cognitive combined training improved gait speed (MD 0.06 m/s; 95% CI 0.02-0.11) and balance (SMD 0.38; 95% CI 0.14-0.61) in cognitively healthy older adults.
Why the study?
The study aimed to evaluate the effects of exercise cognitive combined training compared with non-exercise cognitive combined training on physical function in cognitively healthy older adults.

Does exercise cognitive combined training improve physical function in cognitively healthy older adults?
Mean Difference: 0.06 (95% CI 0.02–0.11)
Simultaneous exercise cognitive combined training improves physical function, including gait speed and balance, in cognitively healthy older adults.
Supports combined exercise-cognitive training to improve gait and balance in older adults; reinforces multimodal interventions for healthy aging.
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.

Li et al. (2022) conducted a meta-analysis in cognitively healthy older adults (n=1,091). Exercise cognitive combined training (ECCT) vs. non-ECCT was evaluated on gait speed (MD 0.06, 95% CI 0.02, 0.11). Exercise cognitive combined training improved gait speed (MD 0.06 m/s; 95% CI 0.02-0.11) and balance (SMD 0.38; 95% CI 0.14-0.61) in cognitively healthy older adults.
