[Diet and exercise influence on the proteomic profile of an athlete population]

Nutrition has emerged as a fundamental tool included in the training program of athletes. Body composition seeks different objectives depending on type of sport, position, or time of the season. Furthermore, analysis proteomics allows us to know the structure and function of proteins.

To study, using proteomics, the influence of two different diets on the anthropometric profile in a rugby players group.

It is a prospective and interventionist study. Thirty-two rugby players were included. Two groups were defined, one followed proteic diet (PD) and, the other group subscribed the Mediterranean diet (MD). All participants were evaluated anthropometrically at the beginning and after six months. A blood sample was taken to twenty -two players, half of each group, used for the proteomic analysis.

MD highlight more benefit for these athletes. Two groups were defined based on their anthropometric behavior, G1 and G2. The proteomic analysis related significantly some TGF-family mediators with these groups.

MD improves the muscular mass without increasing the total body weight, so this data could be determinant to define profiles for athletes. Some TGF-members could be implicated in the adipose tissue and muscular mass balance.
