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.

Power
Physical performance is measured by direct variables evaluated by the power roller (average power, maximum power, etc.).
Time frame: It will be measured on two different occasions. Day one and seven days later with acute consumption of product.
Distance covered
Physical performance is measured by direct variables evaluated by the power roller.
Time frame: It will be measured on two different occasions. Day one and seven days later with acute consumption of product.
Fatigue
Rate of perceived exertion, assessed by the 10-point modified Borg Scale.
Time frame: Change of baseline rate of perceived exertion at seven days
Paresthesia test
Visual analogue scale (1-10)
Time frame: It will be measured on two different occasions. on day 1 (before consumption) and seven days after (after consumption).
Microcapillary blood
This test provides biochemical variables (ABL90FLEX) with 70 ml of capillary blood (Na, K, Glucose, Lactate, etc). It is used to evaluate the effort made by the cyclist.
Time frame: It will be measured on two different occasions. Day one and seven days later.
Lactate
Lactate levels will be measured using the Lactate Pro
Time frame: It will be measured on two different occasions. Day one and seven days later.
Heart Rate
The heart rate will be evaluated by means of a heart rate strap.
