Os efeitos da creatina no desempenho de praticantes de modalidades aeróbicas: uma revisão de literatura

Abstract

Objective: To analyze, through a literature review, the effects of creatine supplementation on physical performance and muscle strengthening in practitioners of aerobic modalities. Methods: This is an integrative review using the PubMed database. The search strategy was structured according to the PICO model, considering as the population resistance exercise practitioners, the intervention as creatine supplementation, the comparison with the placebo effect in resistance exercise practitioners, and the outcomes related to speed, power, muscle recovery, and strength gain. Randomized clinical trials published between 2010 and 2025 were selected, including healthy individuals aged 18 to 64 years. Results: Nine studies met the eligibility criteria. Most showed high methodological quality according to the Jadad Scale. It was observed that creatine monohydrate promoted consistent improvements in criteria such as maximal strength, anaerobic power, and muscle recovery, especially in intermittent or high-intensity training sessions. In endurance sports, the effects of supplementation were heterogeneous, with punctual improvements in final sprints and work capacity above critical power, without significant impact on classical aerobic endurance parameters. Conclusion: Creatine supplementation proved to be effective and safe for increasing muscle strength and power, showing ergogenic potential in repeated high-intensity efforts. Its benefits in predominantly aerobic modalities remain inconclusive, requiring further investigations with greater methodological control and longer duration.
