유산소 운동 중재가 경도인지장애 노인의 인지기능에 미치는 효과: 체계적 문험고찰과 메타분석

Abstract

The objective of this study was to evaluate the specific effects of aerobic exercise on overall cognitive function, memory, and executive function 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 exercise type, frequency, duration, and exercise intensity 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 exercise markedly enhances overall cognitive function, 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, with an exercise intensity of 60-80% HRmax can produce better intervention outcomes. However, due to the unknown optimal mechanisms, further rigorous, large-scale RCTs are imperative to enhance our understanding and refine intervention strategies.
