Efeito da oferta dietética de proteína sobre o ganho muscular, balanço nitrogenado e cinética da 15N-glicina de atletas em treinamento de musculação

Abstract: RESUMOO efeito da oferta crescente de proteína sobre o ganho muscular, balanço nitrogenado e cinética da 15 N-glicina de atletas de musculação foi estudado em seis jovens saudáveis, praticantes de treinamento com pesos (> 2 anos), sem uso de anabolizantes e concordes com os princípios éticos da pesquisa. Todos receberam adequações dietéticas (0,88g de proteína/kg/dia) pré-experimento de 2 semanas (D1) após o que se ofereceu, por idêntico período, dieta contendo 1,5g de proteína/kg de peso corporal/dia com 30kc… Show more

“…Increase in protein offer (2.5g/kg de weight/day) was not different concerning muscle gain 16 . Cyrinoet al 17 , in a similar study with six male bodybuilders suggest that protein ingestion between 1.5 and 2.5g of protein/kg body weight/day, associated with weight training, can significantly contribute to the strength and muscle mass increase In the present study, similar results were found in which the three classifications of LWA ingestion were statistically significant, current lean mass was higher than the initial lean mass in all groups; however, concerning the LWA ingestion within the recommended range and above recommendation, greater significant result was observed.…”

“…[22] Proteins are organic compounds most common in an organism, are present in all cellular structures composing intercellular substances, hormones and antibodies, stand out for their diversity of functions in the body, as main actions are evidenced, as enzyme catalysts, carriers of hemoglobin and myoglobin, protective of antibodies, fibrinogen and cytokines. [23] Because it is an essential macronutrient, the consumption of the protein is necessary for the human being to remain healthy, since they are part of the biological structure, so that the construction and maintenance of the human organism depend on the supply of this macronutrient, among its various functions proteins , also act to prevent and combat major infections and infectious diseases. [23] Protein-caloric malnutrition depresses the humoral and cellular immune function, reducing fractions of the complement system, number, proliferation and function of the circulating T lymphocytes (consequently the production of cytokines), and altering the recognition of antigens.…”

“…Os aminoácidos essenciais são igualmente eficientes à mistura completa dos 20 aminoácidos que constituem nosso corpo na promoção da síntese proteica. Da mesma forma, uma mistura de aminoácidos de cadeia ramificada é tão eficiente quando todos os aminoácidos essenciais reunidos [8]. Segundo Vianna e colaboradores [4], o estímulo da síntese proteica pela leucina isolada tem a mesma eficácia que o estímulo dado pelo BCAA.…”
