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

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 1 day. They will have to take four intakes every hour and a quarter, on the same day.

The study subjects will have to make 2 visits to the laboratory. In the first one, they will have to perform a 10-minute time trial, without consumption. In the second visit, they will perform the same performance test but with acute consumption of the product. Their physical and physiological performance will be evaluated.

The two tests will be separated by 7 days.

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.
