Ingestion of Beta-alanine Effects in Well-trained Tennis Players (BETA_TENNIS)

June 16, 2022 updated by: Universidad Francisco de Vitoria

Ingestion of Beta-alanine Improves Neuromuscular Performance in Well-trained Tennis. A Randomized Controlled Trial.

Beta-alanine is considered as ergogenic aids with good to strong evidence for improving sports performance in specific sports context scenarios. However, most of the studies has been realized in endurance, with limited evidence in intermittent sports, especially in racket sports. Thus, the aim of this study was to explore the effects of 4-weeks ingestion of beta-alanine on neuromuscular performance in well-trained tennis players.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Fourteen tennis players (23.3 ±3.7 years) between 50-250 national tennis ranking participated in this study. Participants were randomly divided into two groups that realized a neuromuscular battery after beta-alanine (4.8 gr/daily during 4-weeks) or placebo (i.e., fructose) (4.8 grams/daily during 4-weeks). Before and after the supplementation period tennis performed a neuromuscular test battery in a tennis court consisted in different test such as; serve velocity, countermovement jump, isometric handgrip strength, 10-m sprint, modified 5-0-5 agility test and repeated sprint ability. After 48 h of the realization of neuromuscular test battery, tennis players performed VO2max consumption test (i.e., treadmill).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
