ABSTRACT
The aim was to investigate the effects of HMB supplementation on the physical performance and anthropometric parameters of Wistar rats that underwent eight weeks of concurrent training. We used 22 male Wistar rats of approximately 60 days of age, And were divided into four groups: control (C), supplemented control (SC), exercise (E) and supplemented exercise (SE). The training consisted of 30 minutes of swimming with an overload corresponding to 70 % of the anaerobic threshold, a one-minute interval, and four sets of ten jumps in water with a one minute interval between sets and a load of 50 % of body weight. After the tests, the tLIM and tTESTE were obtained and used to evaluate the performance of the animals, and anthropometric indices evaluated. The weight increases during the treatment in the SC animals was significantly higher than the animals in groups C and E. The absolute weight of the muscles, kidney and epididymal fat showed higher values for the SC and SE groups in relation to the others.
Se investigaron los efectos de la suplementación con HMB en el rendimiento físico y los parámetros antropométricos de ratas Wistar sometidas a ocho semanas de entrenamiento concurrente. La muestra consistió en 22 ratas Wistar machos, aproximadamente de 60 días de edad, los que fueron divididos en cuatro grupos: control (C), control suplementado (CS), ejercicio (E) y ejercicio suplementado (ES). El entrenamiento consistió en 30 minutos de natación correspondiente a 70 % de la sobrecarga del umbral anaeróbico, un intervalo de un minuto y cuatro series de diez saltos en el agua con intervalo de un minuto entre series y una carga del 50 % del peso del cuerpo. El tLIM y tTESTE se utilizaron para evaluar el rendimiento de los animales, y los índices antropométricos. El aumento de peso durante el tratamiento CS fue significativamente más alto que las de los grupos C y E. El peso absoluto de los músculos, los riñones y la grasa del epidídimo mostraron valores más altos en los grupos CS y ES en relación con los demás.

O exercício físico fera uma série de alterações fisiológicas ligadas à saúde e ao desempenho físico. Nesse sentido, o objetivo do presente estudo foi analisar os efeitos do treinamento concorrente na musculatura e composição corporal de ratos Wistar. Na presente pesquisa foram analisados 11 ratos machos adultos (90 dias), sendo utilizados seis como grupo de controle e cinco definidos como Treinamento Concorrente. O protocolo de TCc foi definido com 30 minutos de natação e 4 séries de 10 saltos, com sobrecarga de 50% do peso corporal do animal. A intensidade do treino aeróbico foi estabelecida em 70% do limiar anaeróbico, estimado a partir da carga crítica de trabalho, definida com a aplicação de quatro diferentes estímulos com cargas correspondentes a 7, 9, 11 e 13% do peso corporal de cada animal, em dias consecutivos.
Exercise beast a series of physiological changes related to health and physical performance. Accordingly, the aim of this study was to analyze the effects of concurrent training on muscle and body composition in Wistar rats. In this 11 adult male rats (90 days), six being used as a control group and five defined as Competitor Training survey were analyzed. The CBT protocol was set to 30 minutes swimming and 4 series of 10 jumps, loaded with 50% of the body weight of the animal. The aerobic intensity of training was established in 70% of the anaerobic threshold, estimated from the critical load, defined as the application of loads with four different stimuli corresponding to 7, 9, 11 and 13% of the body weight of each animal, on consecutive days.
