Study to Analyze the Aerobic Performance Efficacy of Chronic Intake With a β-alanine Supplement in Recreational Cyclists

Not Applicable

Completed

• Conditions: Beta Alanine Supplementation

• Registration Number: NCT06167395
• Lead Sponsor: Universidad Católica San Antonio de Murcia

Brief Summary

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

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 30 days. They will have to take 4 intakes every three hours, being the first intake two hours after waking up.

The study subjects will have to make 2 visits to the laboratory. At the first and last visit, their aerobic performance will be evaluated by an incremental test to exhaustion with gas analysis.

Primary Outcome Measures

Name	Time	Method
Power	Change in performance after 30 days of product consumption	Measured using a cyclus 2 roller.
Distance	Change in performance after 30 days of product consumption	Measured using a cyclus 2 roller.

Secondary Outcome Measures

Name	Time	Method
Anaerobic treshold	It will be measured twice, once at baseline or at the end of the study after 30 days.	Through a stress test with gas analysis
Maximum oxygen consumption	It will be measured twice, once at baseline or at the end of the study after 30 days.	Through a stress test with gas analysis
Microcapillary blood	It will be measured twice, once at baseline or at the end of the study after 30 days.	This test provides biochemical variables (ABL90FLEX) with 70 ml of capillary blood.
Lactate	It will be measured twice, once at baseline or at the end of the study after 30 days.	Lactate levels will be measured using the Lactate Pro 2
Aerobic threshold	It will be measured twice, once at baseline or at the end of the study after 30 days.	Through a stress test with gas analysis
Heart Rate	It will be measured twice, once at baseline or at the end of the study after 30 days.	The heart rate will be evaluated by means of a heart rate strap.
Fatigue	It will be measured twice, once at baseline or at the end of the study after 30 days.	Rate of perceived exertion
