Abstract

Objective: To evaluate the effects of creatine supplementation on the strength and musculature of the elderly. Method: Review of randomized clinical trials found in SciELO and Pubmed electronic databases according to the search terms: “creatine” AND “dietary supplementation” OR “elderly” OR “muscle strength” OR “sarcopenia”. For inclusion of the article in the selection, the following criteria were used: randomized clinical trials controlled by placebo carried out with people aged over 64 years, published in the last 10 years, in Portuguese and English. Review articles, meta-analyses, opinion and technical publications on the subject were discarded. Results: The analyzed studies analyzed a total of 452 participants (142 men and 310 women) lasting from eight weeks to one year. Five grams of administered supplementation or 0.1 mg/kg of body weight were adopted as dosing protocols. The main findings of this analysis demonstrated that creatine supplementation promotes an increase in lean mass and strength during physical exercise. Conclusion: The use of creatine had positive effects for the development of muscle tissue in the elderly, when combined with the practice of resistance training.
