Abstract

OLIVEIRA, Patrícia Veiga de; BAPTISTA, Luciana; MOREIRA, Fernando  and  LANCHA JUNIOR, Antônio Herbert. Correlation between the protein and carbohydrate supplement and anthropometric and strength variables in individuals submitted to a resistance training program. Rev Bras Med Esporte [online]. 2006, vol.12, n.1, pp.51-55. ISSN 1806-9940.  https://doi.org/10.1590/S1517-86922006000100010.

The majority of individuals following regular resistance exercise trainings have a major esthetic concern that may be summarized through the increase in the strength and muscular mass under the training associated to the supplement. The purpose of this paper was to verify if the intake of a high protein diet (4 g.kg-1.d-1) associated to the training causes a higher increase in the muscular mass and strength compared to the normo protein dietetic pattern. METHODOLOGY: Sixteen volunteers were divided in two groups according to the supplement pattern: a total of 4 g.kg-1.d-1 protein (HP), and carbohydrate (NP) intake following the caloric quantity of the protein supplement (225 g.d-1). Both groups were submitted to the resistance training protocol to the biceps and triceps muscles three times a week for 8 weeks. It was analyzed the strength, the muscular mass, the muscular cross section area, the cortisol and the insulin. RESULTS: The HP group presented higher protein intake, and the NP group presented higher carbohydrate intake. Both groups also presented a difference in the cortisol values. The NP group presented a positive correlation between the higher carbohydrate intake (%) and the increase in the muscle area, and also between the strength to the overhead triceps, and the increase in the muscular mass and the higher carbohydrate intake. CONCLUSION: It is suggested that the correlation between the carbohydrate intake and the increase in the muscular area and strength to the overhead triceps found in the NP group is related to the favorable metabolic situation to the protein synthesis.
