• The effects of different types of exercise on cognitive function in the older adults: a systematic review and network meta-analysis (2026) · Frontiers in Public Health · doi

  Firstly, the primary outcome measures in this study included MMSE, MoCA, WAIS, and WCST. However, cognitive function is also correlated with exercise dosage and heart rate variability (HRV), in addition to exercise modality. Due to methodological included studies, we were unable to inconsistencies across systematically evaluate the independent effects of different exercise modalities on cognitive function and associated executive functions. Secondly, the substantial heterogeneity observed in some results may be attributed to variations in cognitive assessment protocols and exercise intervention designs. Future researchers should conduct in accordance with standardized guidelines for measuring independent variables (e.g., exercise parameters) and dependent variables (e.g., cognitive outcomes). This standardization will reduce inter-study heterogeneity and enhance the comparability of results. studies Thirdly, exercise intensity, gender, and age-related factors may moderate the effects of different exercise modalities on cognitive function in older adults. Most included studies did not report standardized exercise intensity, which prevented further subgroup analysis based on intensity and may have contributed to statistical heterogeneity. Additionally, the inherent limitations of network Meta-analysis should be noted: some exercise type pairs (e.g., ST vs.

• Rethinking exercise dose for cognitive ageing: a systematic review and meta-analysis of physical dose and cognitive–motor demands (2026) · Frontiers in Psychology · doi

  The field lacks a clear account of what constitutes an effective dose of exercise for cognitive ageing. Current trials quantify physical exposure more consistently than cognitive-motor operations. There is a need for a systematic review and meta-analysis of the effect of exercise on cognitive ageing.

• Breaking Cognitive Barriers: Comparing Neurobic and Aerobic Approaches in Dementia Care (2026) · OBM Neurobiology · doi

  There is a lack of research on the effects of neurobic and aerobic approaches in dementia care. There is a need for studies that investigate the effectiveness of exercise-based interventions for dementia care. There is a gap in the understanding of the mechanisms by which exercise improves cognitive performance in older adults.

  Consequently, further investigation is warranted to determine whether tailored guidelines-such as variations in the frequency and duration of resistance exercise-should be established for patients with varying levels of dementia, in order to optimize the benefits for those experiencing cognitive impairment.

• Effects of exercise on cognitive function in older adults: a systematic review and meta-analysis of the mediating role of sleep (2026) · Frontiers in Human Neuroscience · doi

  The underlying mechanisms of the exercise-cognition relationship in older adults are not well understood. The role of sleep quality in mediating this relationship has not been fully investigated. There is a need for a systematic review and meta-analysis to synthesize the current evidence and provide a comprehensive overview of the relationship between exercise, sleep, and cognitive function in older adults.

• Motor and functional correlates of cognitive performance in older adults (2026) · Romanian Journal of Neurology · doi

  Future studies should investigate the longitudinal relationships between cognitive function and functional status in older adults. Research should explore the development of personalized interventions to promote cognitive health in older adults. Studies should examine the effectiveness of interventions aimed at promoting cognitive health in older adults.
