Efeitos do treinamento resistido combinado à suplementação de vitamina D sobre a cognição da pessoa idosa: uma revisão sistemática.

Abstract

This study aimed to identify, through a systematic review, what are the effects of Resistance Training (RT) combined with Vitamin D supplementation (VITD) on the cognition of elderly people. The studies were rescued through the search with keywords related to aging, RT, VITD and cognition, and their respective meanings in the databases. Of the retrieved articles, four were included in this review to meet the eligibility criteria in the selection process. The average age of the samples was 75.3 years, with different clinical profiles, being distributed among healthy people, with a report of a recent fall, it was early or with a level of cognitive impairment. Studies have introduced RT using different prescription parameters, as well as the dosage of VITD supplementation. To assess the individuals' cognitive status, the Mini-Mental State Examination was used in two versions: original and Korean, and the Montreal Cognitive Assessment. Only one of the reported studies significantly improved cognition after the intervention period, although it did not show differences between the group that supplemented VITD and the one that did not. The clinical condition and age group of the individuals participating in the studies can influence the lack of experimental results. The lack of information on prescription parameters of RT variables indicates that there is no consensus on what is the appropriate prescription in order to improve the cognition of elderly individuals. The results found in this review do not confirm the benefits of RT and VITD supplementation in the cognition of the elderly, suggesting that further experimental studies are still needed in order to fill a gap on how RT to VITD can benefit the cognitive aspects of elderly people. .
