About this study

Official title: Effects of Creatine Supplementation and Resistance Training on Lean Mass, Sleep, Muscular Strength, and Perceived Menstrual Cycle Symptoms in Premenopausal Females

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.

Read the detailed description

This study will be a 6 week creatine monohydrate and resistance training intervention with performance familiarization and pre and post testing. Participants will report to the Human Performance Laboratory (HPL), having fasted from alcohol, caffeine, and exercise for a minimum of 12-hours, for pre testing and to sign an informed consent explaining the procedures and potential risks and benefits of participation. Participants will then provide one urine sample to determine proper hydration status for body composition assessment. Next, participants will complete a physical activity readiness questionnaire (PARQ+) prior to performing any physical tasks. Participants will complete a daily menstrual cycle log, fatigue questionnaire, and health history survey. Prior to body composition testing, participants will complete a dual-energy x-ray apsorptiometry (DXA) scan consent for to ensure absence of pregnancy. Then, a full-body DXA scan will be completed along with an InBody bioelectrical impedance analysis. Following body composition testing, participants will be fitted for an Oura ring to track their sleep. Lastly, muscular strength will be assessed using the Tonal. Following a 5-minute full-body warm up, 1-repetition maximum will be determined using two upper body and two lower body exercises at maximal effort. Upon conclusion of pre-testing, participants will be randomized into two groups: 1) creatine monohydrate (5g/d creatine monohydrate + 5g/d maltodextrin) or 2) placebo (10 g/d maltodextrin) for 42 consecutive days. Participants will visit the HPL daily to consume their respective supplement as well as provide a urine sample for ovulation status determination. Additionally, participants will complete two resistance training sessions on non-consecutive days using the Tonal per week for 6-weeks. Following 6-weeks, post-testing will occur and includes the same procedures as pre-testing.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Body Composition

    Change in lean mass (kg, %) using a DXA scan from baseline after 42 days

    Measured: 42 days

  2. Sleep

    Change in sleep (hours, minutes, REM) using the Oura Ring application tracking from baseline after 42 days

    Measured: 42 days

  3. Muscular Strength

    Change in muscular strength (1-repetition maximum) using the Tonal from baseline after 42 days

    Measured: 42 days

  4. Perceived Menstrual Cycle Symptoms

    Change in perceived menstrual cycle symptoms (fatigue, cramping, bloating) using menstrual cycle questionnaires from baseline after 42 days

    Measured: 42 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Creatine Monohydrate Supplementation in people with Health Behavior, run by University of Idaho at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Body Composition (time frame: 42 days). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Sep 2023.
