Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are females aged 18 to 25 who are recreationally active and engage in structured resistance training.
✕Probably not a fit
Patients with recent musculoskeletal injuries or those using performance-enhancing substances may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study examines the effects of taking creatine monohydrate before sleep on anaerobic performance and muscle recovery in recreationally active females. Participants will be randomly assigned to receive either creatine or a placebo for seven days, with performance assessed through the Wingate Anaerobic Test. Blood samples will be collected to analyze muscle damage markers before and after the supplementation period. The goal is to determine if pre-sleep creatine can enhance performance and recovery in this population.
Why it matters
Potential benefit: If successful, this could lead to improved exercise performance and recovery strategies for recreationally active women.
How similar studies have gone: While there have been studies on creatine supplementation, this specific approach of pre-sleep administration in recreationally active females is relatively novel.
