| 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,... |

| Studies indicate that increasing physical activity and decreasing levels of fat in the liver help to decrease the risk of morbidity from liver conditions. This study aimed to evaluate the effects of an eight week intermittent training program on the liver tissue of rats subjected to a hyperlipidic diet. The study consisted of 30 male Wistar rats, divided into the following groups: Sedentary Control (SC) Exercise Control (EC) (fed on standard feed and water) Sedentary Obese (SO) and Exercise Obese (EO) (fed on bacon, ham, sausage, biscuits, soda and standard feed), which performed intermittent training through electrically stimulated jumps, with three sets of 12 repetitions, three times per week for eight weeks. At the end of the training period, the... |

| 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... |

| The aim of this study was to analyze changes in the skeletal muscle tissue of rats after muscle stretch injury using fractal analysis. Nineteen rats were divided into three groups, Control (n= 5) (C), Lesion two days (n= 7) (L2), and Lesion seven days (n= 7) (L7). Histological slides of the gastrocnemius muscle of the animals were prepared and stained with Hematoxylin and eosin for analysis of the inflammatory process, and picrosirius for the demonstration of collagen. The stained slides were subsequently analyzed using Fractal Dimension (FD). The results showed high FD values of the inflammatory process in the experimental groups L2 and L7 in relation to C (p= 0.000). The analysis of collagen in the picrosirius stained slides showed high FD in the L2... |

| The aim of this study was to analyze the effects of an association of cryotherapy and therapeutic ultrasound on the treatment of muscle injured by impact. Fifty-five Wistar rats were divided into five groups (n = 11), Acute Injury (AI), Injury (I), Cryotherapy (CR), Therapeutic Ultrasound (TU) and Association of Cryotherapy and Therapeutic Ultrasound (CRTU). The CR and CRTU groups received applications of Cryotherapy three times (immediately, 24 and 48 h after injury) of 20 minutes duration. The TU and CRTU groups received applications of Therapeutic Ultrasound for seven days, for five minutes, in pulsed mode, 0.5 w/cm intensity, frequency 1 MHz. Body mass and gastrocnemius mass were analyzed. In addition to histological slides stained with hematoxylin and... |

| The aim of the present study was to observe the changes in the muscle tissue of rats after application of growth hormone (GH) and performing a strength training protocol (ST). In total, 40 male Wistar rats, 60 days old, were used, divided into four groups: control (C), control and application of GH (GHC), strength training (T), and strength training with the application of GH (GHT). The physical training protocol (PT) was composed of four series of 10 jumps in water, 3x/week, with an overload of 50 % of body weight for four weeks. GH was administered intraperitoneally at a dose of 0.2 IU/Kg to the GHC and GHT groups and saline (0.9 % sodium chloride) to the C and T groups. After four weeks of PT, the animals were euthanized and samples taken from the... |
