Creatine supplementation and strength training in young women: a systematic review

Abstract

This study aims to analyze the effects of creatine supplementation combined with strength training on body composition and muscle strength in young women, a less researched population compared to men. A systematic review was conducted following PRISMA guidelines, starting with 195 studies, of which only six met the rigorous inclusion criteria, focusing on randomized controlled trials that investigated these effects in women aged 18 to 30. The results showed that creatine supplementation may increase lean body mass and improve muscle strength in certain exercises, although no significant changes were observed in total body mass or body fat percentage. Additionally, creatine appears to benefit intermittent exercise capacity, particularly in high-intensity, short-duration activities. However, the response to creatine varies among individuals. It is concluded that while creatine may have specific benefits for body composition and muscle strength, further studies are needed to determine optimal doses and long-term effects in this population.
