简要总结
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.
详细描述
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.
