Brief summary
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.
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Fatigue in jumping | Change in initial jump fatigue at 30 days | Measured with a contact platform |
| Aerobic and anaerobic thresholds - VO2max | Change in initial maximal oxygen consumption at 30 days | Measured with a gas analyzer |
| Anaerobic capacity | Change in baseline anaerobic capacity at 30 days | Measured with a Monark cycloergometer |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Microcapillary blood | It will be measured on two different occasions. Day one and 30 days later. | This test provides biochemical variables (ABL90FLEX) with 70 ml of capillary blood. |
| Lactate | 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 | Lactate levels will be measured using the Lactate Pro |
| Safety variables | It will be measured on two different occasions. Day one and 30 days later. | 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. |
