Os efeitos da suplementação de creatina na sarcopenia em idosos: uma revisão de literatura

Abstract

Objective: to review the effects of creatine supplementation on sarcopenia in the elderly. Methods: a review of the narrative literature was carried out using only original articles, of the planned clinical trial type that aimed to evaluate the effect of creatine supplementation on the muscle mass of elderly people undergoing or not undergoing strength training, published in Portuguese and English, in the last 10 years. Results: most studies suggest that creatine supplementation was effective for muscle health and promoted an improvement in physical performance with resistance training. However, most studies point out that creatine supplementation alone is not capable of promoting an increase in muscle fibers, however, when there is an association between this supplementation and strength training, better results were obtained. Conclusion: creatine supplementation has beneficial effects on muscle health, promoting its maintenance and consequently, improving the functionality of the elderly. Therefore, creatine supplementation can increase lean mass and muscle strength in the elderly, but when associated with resistance training, its results are more evident.
