Primary purpose: OTHER

Brief summary: Randomized, controlled, double-blind, double-blind clinical trial, with three parallel arms depending on the product consumed (experimental product dose 1 and dose 2 and placebo product) and single-center, to measure the efficacy of a sustained release beta alanine on the aerobic performance efficacy in recreational cyclist

Detailed description: Subjects meeting the selection criteria will be randomly assigned to each of the study groups (investigational product dose 1 or dose 2, or placebo, depending on the group to which they have been assigned).

The product to be consumed is beta alanine. Participants will consume the product for 30 days. They will have to take 4 intakes every three hours, being the first intake two hours after waking up.

The study subjects will have to make 2 visits to the laboratory. At the first and last visit, their aerobic performance will be evaluated by an incremental test to exhaustion with gas analysis.

Eligibility criteria: Inclusion Criteria:

* Male cyclists with more than two years of cycling experience.
* Perform tests without fatigue.
* Road bike training at least twice a week.

Exclusion Criteria:

* Participants with chronic illness.
* Have a long-term injury that prevents you from training in the previous month.
* Inability to understand informed consent.
* Have consumed beta alanine in the three years prior to the start of the study.
* Consumption of other supplements that may alter performance.
