Effects of Pre-Sleep Creatine on Anaerobic Power and Muscle Recovery in Recreationally Active Females Aged 18 to 25

What this Trial Is About

Researchers are investigating how taking creatine monohydrate before sleep affects anaerobic performance and muscle damage in recreationally active females aged 18 to 25. This randomized, placebo-controlled trial aims to understand if short-term, time-specific creatine supplementation can improve power output and reduce muscle damage markers during exercise. The focus is on evaluating effects through performance tests and blood markers related to muscle recovery. Participants will be randomly assigned to one of two groups one receiving 5 grams of creatine monohydrate powder dissolved in flavored water, and the other receiving a visually identical placebo powder made of maltodextrin. Both supplements are taken 30 minutes before sleep each night for seven consecutive days. The trial compares the impact of creatine versus placebo on anaerobic power and muscle damage. During the study, participants will undergo the Wingate Anaerobic Test at the start and end of the supplementation period to measure average and peak power output as well as fatigue index. Blood samples will be collected before and after the intervention to assess muscle damage markers such as creatine kinase and lactate dehydrogenase. The study includes careful tracking of diet and training routines, with total participation lasting just over one week.
