Abstract
The objective of this study was to evaluate the specific effects of aerobic exercise on overall cognitive function, memory, executive function, and quality of life among older adults diagnosed with Mild Cognitive Impairment (MCI). Additionally, the study aimed to analyze the impact of exercise interventions on older adults with MCI, taking into account the measurement tools, exercise type, frequency, and duration, while also evaluating recommended interventions from randomized controlled trials(RCTs). We reviewed 22 studies from Web of Science, PubMed, Cochrane Library, and EMBASE. The findings of this study indicate that aerobic dance markedly enhances overall cognitive function, effectively elevates quality of life, and demonstrates a modest improvement in memory and executive function among individuals with MCI. Moreover, Subgroup analyses revealed that square dancing had a notably beneficial intervention effect, given its low-cost, easy-to-learn, and inclusive nature. This suggests its suitability for exercise interventions in MCI patients. Additionally, interventions twice a week, each lasting over 50 minutes, yielded better aerobic exercise outcomes. However, due to the unknown optimal mechanisms, further rigorous, large-scale randomized controlled trials are imperative to enhance our understanding and refine intervention strategies.
