The role of regular physical exercise for enhancement of long-term memory in the elderly: a review of recent evidences
Aims: We performed a systematic review of recent literature to discuss the role of physical exercise on cognition of the elderly, especially long-term memory (LTM). Source of data: The articles were sought in scientific journals indexed in Medline through PubMe and PubMed Central websites. In the final yield a total of 8 articles was selected. They show that Exercise programs improving LTM in the elderly involved aerobic activities performed 2-3 times per week. LTM improvements were correlated with brain-specific regions changing volume and depend on intensity, performed at least moderately for a minimum of 2.5 to 3 months. Exercise programs to improve LTM require strict control of exercise intensity, while different training duration and weekly sessions seem effective. Conclusions: Training focusing only in walking sessions requires further investigations to ensure its potential in improving LTM in the elderly.
