About this study

Official title: Effects of Lepidium Meyenii (Maca) Extract Supplementation on Immune Function, Inflammatory Responses, Oxidative Stress After Strenuous Endurance Exercise

The aim of this study is to investigate Lepidium meyenii (Maca) extract supplementation on exercise-induced responses of the biochemical, and physiological parameters.

Read the detailed description

Thirty healthy male participants were divided into Maca group (2.25 g of Maca extract, twice per day for 12 weeks) and placebo group (n = 15). All participants conducted a graded exercise test on treadmill to determine the maximal oxygen consumption (VO2max) before and after supplementation, and the speed equivalent to 70% VO2max was conducted for an exhaustive endurance exercise test by treadmill for 1 hours, followed by 90% VO2max until exhaustion.The time to exhaustion, peak oxygen consumption, maximal heart rate and average heart rate will be recorded during the exercise period. Venous blood samples will be drawn before, immediately after, 2-hour after, 4-hour after, and 24-hour after the exhaustive endurance exercise test. Data was analyzed by Two-way mixed design ANOVA.

Questions about this trial

What is this clinical trial studying?

A study testing maca in people with Healthy, run by Taipei Medical University at 1 site in Taiwan.

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 7 inclusion and 7 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: status not confirmed, as of the sponsor's last update on 22 Mar 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 Taiwan. 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.

Are results available for this study?

Results are not available in the source record.

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?

Concentration of leukocyte (time frame: before exercise). The study lists 175 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05779488.

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 22 Mar 2023; AzTrials last refreshed its copy on 31 Oct 2026.
