Overview
Brief Summary
Randomized, controlled, double-blind, single-center, controlled 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 28-day consumption of a sustained-release beta alanine on the physiological efficacy of physical performance in recreational cyclists.
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 28 days. They will have to take 4 intakes every three hours, the first intake being two hours after waking up. The study subjects will have to make 2 visits to the laboratory. Physical performance and physiological changes will be evaluated with a 10-minute time trial. The first test will be performed without product consumption and the second after 28 days of consumption.

Outcomes
Primary Outcomes
Power
Time Frame: It will be measured on two different occasions. The first day and twenty-eight days later.
Physical performance is measured by direct variables evaluated by the power roller (average power, maximum power, etc.).
Distance covered
Time Frame: It will be measured on two different occasions. The first day and twenty-eight days later.
Physical performance is measured by direct variables evaluated by the power roller.
Secondary Outcomes
- Fatigue(Change of baseline rate of perceived exertion at twenty-eight days)
- Microcapillary blood(It will be measured on two different occasions. Day one and twenty-eight days later.)
- Body weight(The test will be measured at baseline and after 28 days of consumption.)
- Muscle mass(The test will be measured at baseline and after 28 days of consumption.)
- Fat mass(The test will be measured at baseline and after 28 days of consumption.)
- Paresthesia test(It will be measured on two different occasions. on day 1 (before consumption) and twenty-eight days after (after consumption).)
- Lactate(It will be measured on two different occasions. Day one and twenty-eight days later.)
- Heart Rate(It will be measured on two different occasions. Day one and twenty-eight days later.)
- Liver safety variables(It will be measured twice, once at baseline or at the end of the study after 28 days.)
