The exercise-induced collapse (EIC) is a hereditary disease characterized by muscle weakness, impaired locomotion and collapse after intense exercise. This autossomic recessive disorder affects mainly Labrador Retriever presenting the mutation c.767G>T in the dynamin 1 (DNM1) gene. The objective of this study is to report the first case of exercise-induced collapse in Labrador Retriever in Brazil. The molecular test detected the specific genetic mutation and confirmed the clinical diagnosis in a Labrador Retriever with clinical history of weakness and collapse after exercise. It is important to include this disease as part of the differential diagnosis of neuromuscular diseases in Labrador Retriever and use the molecular test to guide matings.

Nowadays the regular practice of sports is known as a way to obtain a better quality of life. On the other hand, the media has been distorting this idea, determining the ideal body as the hypertrophy phenotype. It is well known that the genetic factor does not allow all individuals to have this body shape. Besides the fact that, the anxiety of these people in obtain quick results, as one of the globalization’s consequence, make use of anabolic steroid to achieve this goal. However the bodybuilding or the strength muscle gain, make anabolic steroids users abuse and in major cases the users do not know the side effects. In front of these considerations, the present study evaluated the effects of the treatment with anabolic steroids and/or high intensity physical training on the corporal developing, the reproductive organs, bone parameters (strength and bone deformation) and seminal parameters as well the social behavior (aggressiveness). In other to obtain the experimental group, male Wistar rats were used, with 75 days old. The groups were divided into: Vehicle Non-Training (NV), Anabolic Steroid-Non-Training (NA), Vehicle-Training (TV) and Anabolic Steroid-Training (TA). These rats received i.m. injections, twice a week, of anabolic steroid (5mg/kg per animal of nandrolona decanoate) or vehicle (the same volume of peanut oil per animal) and the group TV and TA were submitted to physical training three times per week, during eight weeks. The body mass, wet weight of reproductive organs, femur and semen of the different groups were measured. The aggressive test was also realized in two steps: the first, within 4 weeks of the treatment and the other step in the end of the treatment, in this period the animal was isolated. It was not observed alterations in body mass of the groups. Though it was observed a benefic effect on the maximum strength of the... (Complete abstract click electronic access below)

Em trabalho anterior, observou-se que diferentes grupamentos musculares submetidos ao teste de exaustão (TE) com pesos respondem semelhantemente com hemoconcentração, acidose e aumento da glicemia, entretanto, com variações grupomuscular dependentes. Nesse estudo, é comparado o efeito do impacto provocado pelo TE envolvendo, conjuntamente, 5, 4 ou 3 exercícios por meio da análise desses marcadores bioquímicos. Foram estudados 21 indivíduos do sexo masculino (20-32 anos) voluntários, familiarizados com treinamento em musculação, estratificados em três grupos de acordo com o número de exercícios: grupo 5 ( n= 6) 5 exercícios (Extensão do cotovelo, desenvolvimento pela frente, supino reto, levantamento terra e agachamento), grupo 4 (n= 7) 4 exercícios (Supino reto, rosca direta com barra, agachamento hack, tríceps no pulley), grupo 3 (n= 8) 3 exercícios (Agachamento hack, supino reto, rosca direta ) . Todos foram submetidos à sobrecarga inicial de 80% de uma repetição máxima (1RM), até a exaustão, em seguida, com auxílio externo e sem interrupção do exercício, a carga foi reduzida em 20% do peso, até a impossibilidade de continuidade de realização do exercício com a carga mínima (20% de 1RM). O sangue coletado em veia cubital antes (At) e imediatamente após (Ap) o TE foi analisado para indicadores hemogasimétricos (pH, pO2, pCO2, HCO- 3), hemoconcentração (Ht) e glicemia. O efeito do TE sobre cada variável (At/Ap) foi avaliado comparando-se os grupos por meio de ANOVA-medidas repetidas para significância de p=0,05. Houve significância (p<0,05) na elevação do Ht, glicose e pO2 e redução do pH, PCO2 e HCO- 3, Entretanto houve diferença significativa entre os grupos apenas em relação ao HCO- 3, no qual este apresentou maior variação no G4 em relação ao demais. Assim, esses marcadores sistêmicos respondem a exaustão muscular de modo semelhante ao envolvimento de 3,4 ou 5 grupamentos musculares

The objective of the present study was to compare in which part (lower limb or upper limb) the repeated bout effect has the greatest magnitude. Twelve males individuals with no recent (6 months) experience with resisted training participated in this study. The subjects were randomly divided into two groups (legs and arms) and came to the laboratory 5 times. 1st) adaptation to the dynamometer. 2nd) to perform one bout of eccentric exercise (EE) and provide markers such as isometric peak torque (IPT), delayed onset muscle soreness (DOMS) (both collected before and after the bout) and concentration of the creatine kinase (CK) enzyme in the blood (only before the bout). 3rd) 48 after the first bout the same markers were collected again. After 14 days, the methodologies used in the 2nd and 3rd visits to the laboratory were repeated respectively to determine the repeated bout effect. A significant decrease of IPT and a significant increase of CK and DOMS were found immediately after and 48 hours after the first bout of EE for the arms group. The legs group showed a significant increase in CK (48 hours after the EE) and DOMS (immediately after the EE) resulting from the first bout. In the arms group, the second bout did not cause significant increase in CK or DOMS on any of the situations, however, it provoked a decrease in force production immediately after the EE. The legs group showed a significant increase of DOMS immediately after the second bout of EE, which caused no significant increase in CK. The only marker in which the repeated bout effect happened for both groups was CK. No significant difference was found between the protections for both groups. Taking into account the results, it’s been discussed whether there is a relation between the susceptibility to muscle damage and the repeated bout effect, and also...(Complete abstract click electronic access below)
