Resumo: | This study was designed to evaluate the effects of diet protein content on skeletal muscle growth in response to anaerobic training in rats. Young male wistar rats were separated into two groups: Normal (N= 17%) and High (H= 35%) protein diet. Each group was subdivided: Sedentary (S) and Trained (T= jumping into the water, supporting a load of 50% of body weight, 10 30-second sessions interrupted by 1 min rest/day, 5 days/week). After 8 weeks gastsrocnemius cell number (DNA content) and size (protein/DNA), carcass, lipid and protein, and blood lactate after 10 exercise sessions were evaluated. All rats showed blood lactate above 8.0 mmol/l after exercise. Gastrocnemius muscle from HT-rats showed increased cell size (8%) in comparison to HS. No differences were observed among the groups in the other variables. These results indicate that the exercise protocol used is anaerobic and that the ingestion of the high protein diet revealed adaptations to anaerobic training that were not expressed while feeding on a normal protein diet. |

Foram utilizados ratos Wistar machos jovens, separados em dois grupos, de acordo com a dieta: Normoprotéico (N= 17%) e Hiperprotéico (H= 35%). Cada grupo foi subdividido em: Sedentário (S) e Treinado (T= saltos na água, suportando carga de 50% do peso corporal, dez sessões de 30 s intercaladas com um minuto de repouso, por oito semanas). Foram determinados 1. no sangue, lactato após dez sessões de exercício; 2. no fígado; 3. no músculo gastrocnêmio, número (teor de DNA) e tamanho (proteína/DNA) das células e 4. na carcaça, proteína e gordura. O lactato sanguíneo após o exercício foi superior a 8,0 mM em todos os grupos. Os ratos HT apresentaram maior tamanho celular (8%) no músculo em relação aos HS. As demais variáveis não sofreram alterações com os tratamentos. Esses resultados indicam que o protocolo de exercício empregado é anaeróbio e que a ingestão da dieta hiperprotéica evidenciou adaptações ao treinamento que não se manifestaram com a normoprotéica.Universidade Estadual Paulista - Câmpus de Rio Claro2010-12-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionDocumento Avaliado por Paresapplication/pdfhttps://www.periodicos.rc.biblioteca.unesp.br/index.php/motriz/article/view/411410.5016/4114Motriz.
