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

Not Applicable
Completed
Conditions
Beta Alanine Supplementation
Interventions
Dietary Supplement: Beta Alanine low dose
Dietary Supplement: Beta Alanine high dose
Dietary 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
NameTimeMethod
PowerIt 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 coveredIt 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
NameTimeMethod
FatigueChange of baseline rate of perceived exertion at seven days

Rate of perceived exertion, assessed by the 10-point modified Borg Scale.

Microcapillary bloodIt 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 RateIt 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 testIt will be measured on two different occasions. on day 1 (before consumption) and seven days after (after consumption).

Visual analogue scale (1-10)

LactateIt will be measured on two different occasions. Day one and seven days later.

Lactate levels will be measured using the Lactate Pro
