Study Overview
Brief Summary
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.
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 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.

Outcomes
Primary Outcomes
Power
Time Frame: It will be measured on two different occasions. Day one and seven days later with acute consumption of product.
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. Day one and seven days later with acute consumption of product.
Physical performance is measured by direct variables evaluated by the power roller.
Secondary Outcomes
- Fatigue(Change of baseline rate of perceived exertion at seven days)
- Microcapillary blood(It will be measured on two different occasions. Day one and seven days later.)
- Heart Rate(It will be measured on two different occasions. Day one and seven days later.)
- Paresthesia test(It will be measured on two different occasions. on day 1 (before consumption) and seven days after (after consumption).)
