13. Efeitos de diferentes intervalos de recuperação entre séries de exercícios isocinéticos nas respostas metabólicas e neuromusculares na performance muscular em crianças e adolescentes
PURPOSE: To compare the effect of two different between set RI of isokinetic knee extension exercise on Peak Torque (PT), Total Work (TW), and Blood Lactate (BLa) between children and adolescents. METHODS: 18 children (11.1 0.52 yrs) and 18 adolescents (15.8 0.49 yrs) performed 3 sets of 10 unilateral isokinetic knee extension repetitions at 60/s. The betwee

15. Toxicological parameters in silver catfish (Rhamdia quelen) exposed to cadmium / Parâmetros toxicológicos em jundiás (Rhamdia quelen) expostos ao cádmio
The aquatic ecosystems may be constantly receiving metals from industrial discharges and agriculture generated by anthropogenic activities. Thus, the organisms in the aquatic environment may be the target of these contaminants. The aim of this study was verify cadmium effects on silver catfish (Rhamdia quelen) metabolism. First was verified the lethal concen

16. Reactive oxygen species as signaling molecules of contraction-mediated metabolic responses in skeletal muscle. / Espécies reativas de oxigênio como sinalizadores das respostas metabólicas mediadas por contração no músculo esquelético.
Contractile activity is a potent stimulus for induce changes in glucose and fatty acid metabolism in skeletal muscle. During muscle contraction, the production of reactive oxygen species (ROS) is increased. The purpose of this study was evaluate the effect of removal of ROS, induced by treatment with the antioxidant N-Acetylcysteine, on glucose uptake, activ

17. Determinação das atividades séricas de creatina quinase, lactato desidrogenase e aspartato aminotransferase em eqüinos de diferentes categorias de atividade
The creatine kinase (CK), lactate dehydrogenase (LDH), and aspartate aminotransferase (AST) seric activities in horses of different activity classes (athlete, traction, and reproduction), were compared. Fifty-eight horses were alloted into three groups - group 1 with 20 athletes, "vaquejada" competitors; group 2 with 20 breeding horses; and group 3 with 18 d

18. The supplementation with fatty poliinsaturated omega-3 acids reduced the plasmatic concentration of pro-inflammatory eicosanoids of the lactate desidrogenase enzyme and muscular lesions in rats submitted to sessions of swimming. / A suplementação com acidos graxos polinsaturados omega-3 reduziu a concentração plasmatica de eicosanoides pro-inflamatorios, da enzima lactato desidrogenase e de lesões musculares em ratos submetidos a sessões de natação.
The use of antiinflammatory drugs is common among athletes in which the prevalence of muscular lesions is elevated in training and competition periods. However, some of those drugs have an immunosuppression action, and when used in high dosages or for long time can provoke a decrease in the immunological responses. The objective of the present Thesis was to

19. Influencia da suplementação de proteinas do soro de leite na composição corporal, desempenho fisico e parametros bioquimicos de atletas juvenis de futebol. / Influence of the supplementation with whey proteins in body composition, physical performance and biochemistry parameters of young soccer players.
The soccer as well as other sporting modalities comes using the knowledge produced for training the athletes. These better training results in large distances covered during the game. So the better preparation of the muscle is need for the soccer players. The physical activity raises the proteins requirements, however, how much is not known accurately. The m

20. Effect of dietary magnesium deficiency on oxidative metabolism in tissues of rats submitted to exercise training / Efeito da deficiência dietética de magnésio no metabolismo oxidativo de tecidos de ratos submetidos a protocolo de treinamento periodizado
This study aimed to verify if the ingestion of a diet poor in magnesium alters the oxidative metabolism in rats submitted to moderate physical activity. Male Wistar rats (initial body mass of 280 g) were divided into 4 groups: control (CON, n=9), exercised control (CONEX, n=9), deficient in Mg (MARG, n=9), and exercised and deficient in Mg (EXMARG, n=9).

21. β - NADH DIMINUI A SENSIBILIDADE DA SUCINATO DESIDROGENASE A INIBIÇÃO POR ÁCIDO METILMALÔNICO / β-NADH REDUCES SUCCINATE DEHYDROGENASE SENSITIVITY TO THE COMPETITIVE INHIBITOR METHYLMALONIC ACID IN CEREBRAL CORTEX OF RATS
Methylmalonic acidemia, one of the most frequent organic acidemias, is caused by deficiency of the methylmalonyl CoA mutase, leading to tissue accumulation of Lmethylmalolonic acid (MMA). Affects individuals present lethargy, coma, vomiting, muscular hypotonia, recurrent episodes of metabolic acidosis and progressive encephalopathy. In this context, it has b

22. Efeito da depleção prévia de glicogênio muscular sobre o tempo de exaustão em exercício de diferentes domínios fisiológicos
O objetivo do presente estudo foi avaliar o efeito da depleção prévia de glicogênio muscular sobre o tempo de exaustão em exercício abaixo e acima de do segundo limiar de lactato. Sete indivíduos foram submetidos a um teste progressivo (20 W.min-1) até a exaustão, com determinação do VO2max, do primeiro (LL1) e do segundo (LL2) limiar de lactato.

Several researchers have been accomplished by the scientific community with the goal of evaluating the swine welfare during the stunning, however, most of these studies doesn t represent the stunning conditions and genetic background of pigs produced and marketed in Brazil. The present study had as main goal, evaluate the influence of genetic background of t

24. Physical training associated to tumor growth and nutritional suplementation in Walker 256 tumor-bearing rats / Atividade fisica associada ao crescimento tumoral e suplementação nutricional : estudo experimental em ratos jovens portadores do carcinossarcoma de Walker 256
The intense nutrients mobilisation of the host carcass tissue, in function of the neoplastic growth, leads to the host cachexia. Present in most of the patients with cancer, the cachexia is the state characterized by the involuntary weight loss that overtakes the protein muscle depletion increasing the degradation and/or decreasing the protein synthesis proc
