Study to Analyze the Efficacy of Acute Intake With a β-alanine Supplement in Recreational Cyclists
- Conditions
- Beta Alanine Supplementation
- Interventions
- Dietary Supplement: Beta Alanine low doseDietary Supplement: Beta Alanine high doseDietary Supplement: Control group
- Registration Number
- NCT06180512
- Lead Sponsor
- Universidad Católica San Antonio de Murcia
- 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.

- Primary Outcome Measures
Name Time Method Power 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 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 Outcome Measures
Name Time Method Fatigue Change of baseline rate of perceived exertion at seven days Rate of perceived exertion, assessed by the 10-point modified Borg Scale.
Microcapillary blood It will be measured on two different occasions. Day one and seven days later. 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.
Heart Rate It will be measured on two different occasions. Day one and seven days later. The heart rate will be evaluated by means of a heart rate strap.
Paresthesia test It will be measured on two different occasions. on day 1 (before consumption) and seven days after (after consumption). Visual analogue scale (1-10)
Lactate It will be measured on two different occasions. Day one and seven days later. Lactate levels will be measured using the Lactate Pro
