Changes in Body Composition When Ingesting a Dairy Compound Enriched With Leucine (LEUCI)

20 mai 2020 mis à jour par: Francisco Javier López Román, Universidad Católica San Antonio de Murcia

Randomized Clinical Trial on Changes in Body Composition When Ingesting a Dairy Compound Enriched With Leucine Daily for 3 Months

Controlled clinical trial, randomized by strata (sex and period of the study), with 6 parallel branches to the study depending on the type of product consumed and the type of physical exercise program performed, double-blind masked for the consumption of the product and single-center.

Aperçu de l'étude

Description détaillée

The subjects that meet the selection criteria will make a total of seven visits to the research laboratory (two of them to collect product) and will carry out the pre-established tests in the protocol. Subsequently, a statistical analysis will be carried out with the variables measured in the study to obtain results.
