NCT05745870

Brief Summary

The goal of this clinical trial is to determine the effects of creatine monohydrate and resistance training on lean mass, sleep, muscular strength, and perceived menstrual cycle symptoms in untrained premenopausal females. The main questions it aims to answer are: 1) Does creatine monohydrate supplementation improve body composition, muscular strength, and sleep? 2) Does creatine monohydrate decrease perceived menstrual cycle symptoms compared to a placebo control? Participants will be asked to consume creatine monohydrate daily for 42 consecutive days and well as perform a daily ovulation test. Pre and post testing will include assessments of urine specific gravity to determine hydration status, body composition testing, muscular strength testing and questionnaires. Researchers will compare creatine monohydrate supplementation to a maltodextrin control to see if body composition, sleep, muscular strength, and perceived menstrual cycle symptoms are improved following 6-weeks.
