“…There seems to be evidence that when used 3x/week, concurrent training is capable of generating increased physical capacity, in particular, promoting muscle hypertrophy. Published studies using this training methodology demonstrated significant increases in the crosssectional area and smallest diameters of the muscle fibers of rats, both in aquatic environments and soil exercises, with normal and hypercaloric diets (Castoldi et al, 2013;Machado et al;Castoldi et al, 2017).…”

“…However, one of the major controversies regarding CT is the gain or decrease in muscular strength. While the creator of CT points to a decrease in physical capacity (Hickson, 1980), current findings show that, depending on the way it is used, it can be an effective way to increase performance (Castoldi et al, 2013;Machado et al, 2014). Furthermore, the effects of high-calorie diets have not been explored in conjunction with this type of training.…”

To analyze the effects of concurrent training (CT) on the muscle fibers of Wistar rats submitted to standard and hypercaloric diets. In total, 40 rats were used, divided into 4 groups: Sedentary Group (GS); Exercise Group (GE), Obese Sedentary Group (OS) and Obese Exercise Group (OE). The animals performed a CT protocol consisting of: muscle strength training and aerobic training, carried out 3 times a week for 45 days. The smallest diameter of muscle fibers (MDF) was analyzed to evaluate muscle hypertrophy. It was observed that the OE group presented a significant decrease in MDF, compared to the OS group (OE=77.41 µm vs. OS=98.58 µm). In addition, the animals that performed CT demonstrated muscle hypertrophy (GE=74.39 µm vs. GS=72.13 µm). In conclusion, the CT with a standard diet promoted an increase in MDF while CT with a hypercaloric diet resulted in a decrease.

“…The determination of C AER by means of the critical load (CC) was obtained by inducing the exercise in four randomized stimuli and loads corresponding to 7, 9, 11 and 13% of body weight (PC), so that all animals performed four efforts and reached exhaustion between two and ten minutes, as proposed by Hill 5 and used by Machado et al 6 . The exercise performance time was controlled with the use of a specific timer (TIMEX®, model 85103).…”

-The aim of this study was to verify the influence of body composition on the C AER of animals submitted to different types of physical training. Twenty-three Wistar rats were divided into groups according to the training protocol: control (CTLE); aerobic training (TAE); anaerobic training (TAN); and concurrent physical training (TCc). The critical load test (CC) was carried out for determining the anaerobic threshold at the beginning and end of the training period. TAE was composed of swimming exercise with intensity corresponding to 70% of the anaerobic threshold; TAN was composed of water jumps with overload of 50% of the body weight of each animal; and TCc was composed of a combination of aerobic and anaerobic protocols described above. After four weeks of training, the weight of epididymal adipose tissue and soleus, plantar and gastrocnemius muscles was collected and measured. Dispersion analysis was used to draw graphics and analysis of the simple linear regression model was performed to identify the influence of each variable on C AER . Body Fat demonstrated positive influence of 5% on the relationship with the Anaerobic Threshold. Soleus and gastrocnemius muscles showed negative influence of 13.1% and 37.0%, respectively. The plantaris muscle showed no influence on the Anaerobic Threshold. Body composition influenced the C AER of the animals analyzed. Moreover, it was verified that body fat favored floatability, while higher muscle mass impaired it.Key words: Anaerobic threshold; Rats; Adipose tissue. Resumo -Objetivou-se verificar a influência da composição corporal na C AER de animais submetidos a diferentes tipos de treino físico. Foram utilizados 23 ratos Wistar, divididos em grupos de acordo com o protocolo de treino: controle (CTLE); treino aeróbio (TAE); treino anaeróbio (TAN); e treino físico concorrente (TCc). Foi realizado o Teste de carga crítica (CC) para a determinação do limiar anaeróbio no início e no
