Creatine and Physical Performance
Study Design: Meta-analysis of controlled trials examining creatine supplementation alongside resistance training.
Findings: Creatine supplementation combined with resistance training was associated with greater improvements in weightlifting performance and muscle strength compared with resistance training alone. (1)
Creatine and High-Intensity Exercise
Study Design: Research examining the effects of creatine supplementation on high-intensity and repeated-effort exercise performance.
Findings: Creatine supports the energy systems involved in short-duration, high-intensity exercise and may improve performance during repeated high-intensity efforts. (3)
Creatine and Cognitive Function
Study Design: Systematic review and meta-analysis of randomised controlled trials evaluating creatine supplementation and cognitive outcomes.
Findings: Research suggests that creatine supplementation may improve aspects of cognitive function, particularly memory, although the strength of evidence varies across different cognitive outcomes. (5)
