The Efficacy β-Alanine Supplementation in Performance Outcomes of Road Professional Endurance Cyclists

Universidad Católica San Antonio de Murcia12 enrolled

Overview

A double-blind, placebo-controlled, randomised, with two arms (product and placebo) unicentric clinical trial to analyse the efficacy on physical performance parameters of a product designed for sport during a lapse of two weeks (7 days).

After recruitment, subject will be randomised and allocated to one group of the 2 study arms: treatment group or control group (placebo). A simple randomisation will be performed using software by a random number generator, and assigned to participants.

Outcomes

Primary Outcomes

Fatigue

Rate of perceived exertion

Time frame: Change of baseline rate of perceived exertion at seven days

Secondary Outcomes

Performance outcomes

Physical performance is measured by direct variables: mean power output (MPO) and peak power output by ergometer (Cyclus 2) together with cadence.

Time frame: It will be measured on two different occasions. Day one and seven days later.

Paresthesia test

Visual analogue scale (1-10)

Time frame: It will be measured on three different occasions. Twice on day 1 (before and after consumption) and seven days after.

Microcapillary blood

This test provides biochemical variables (ABL90FLEX).

Time frame: It will be measured on two different occasions. Day one and seven days later.
