About this study

Official title: Experimental Study to Evaluate the Effects of Effects of a Sports Supplement Based on Nitrates and Citrulline Malate on Performance in Professional Soccer Players

Randomized, single-center, parallel, team-stratified, stratified experimental study to evaluate the efficacy of a high sports supplement in improving high-intensity intermittent exercise performance in professional female soccer players.

Read the detailed description

Subjects who meet the selection criteria will be randomly assigned to each of the study groups (investigational product or placebo, depending on the group to which they have been assigned).

The product to be consumed will be Nitrates and Citrulline Malate. Participants will consume the product for 30 days. The intake should be done two hours before each training session and the same dose will be consumed.

The women's soccer players will perform a stress test with gas analysis to measure performance, as well as a Wingate test without consumption of the products. Five days later, the players will perform the Yo-Yo IR1 test in the field and will repeat the same tests performed at the beginning of the test after product consumption.

What is being measured

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

  1. Aerobic and anaerobic thresholds - VO2max

    Measured with a gas analyzer

    Measured: Change in initial maximal oxygen consumption at 30 days

  2. Fatigue in jumping

    Measured with a contact platform

    Measured: Change in initial jump fatigue at 30 days

  3. Anaerobic capacity

    Measured with a Monark cycloergometer

    Measured: Change in baseline anaerobic capacity at 30 days

Secondary outcomes (3)
  1. Microcapillary blood

    This test provides biochemical variables (ABL90FLEX) with 70 ml of capillary blood.

    Measured: It will be measured on two different occasions. Day one and 30 days later.

  2. Lactate

    Lactate levels will be measured using the Lactate Pro

    Measured: It will be measured on two different occasions. One on the first day (without intake of product ) and 30 days later, the same measurements but after having consumed the product

  3. Safety variables

    It is a blood test that measures the presence of some enzymes, proteins and bilirubin in the blood, with the aim of determining if there is any alteration in the liver.

    Measured: It will be measured on two different occasions. Day one and 30 days later.

What is this clinical trial studying?

A study testing Nitrates and Citrulline Malate in people with Supplementation, run by Universidad Católica San Antonio de Murcia at 1 site in Spain.

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 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

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?

Aerobic and anaerobic thresholds - VO2max (time frame: Change in initial maximal oxygen consumption at 30 days). The study lists 3 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.
