Aspectos reprodutivos e sociais e resistência óssea em ratos machos submetidos ao exercício físico e/ou a um anabolizante esteróide

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)

Efeito da suplementação de erva mate (Ilex paraguariensis) sobre a capacidade antioxidante total em atletas futebolistas em teste exaustivo em esteira

Introduction: Physical exercise are related to high oxygen consumption, leading to increase on reactive oxygen species (ROS) generation and subsequent oxidative stress. Concomitantly, physical training can improve the antioxidant defense systems, reducing the deleterious activity of ROS. The yerba mate (Ilex paraguariensis) has several bioactive compounds in its composition, providing important antioxidant activity in improving defense systems and reducing the damage caused by ROS. Few studies related to yerba mate with antioxidant effects during exercise. Objective: Evaluate whether the consumption-based drink yerba mate (Ilex paraguariensis) is able to increase the total antioxidant performance (TAP) after an exhaustive test on a treadmill. Methods: The sample counted with 15 female soccers players from Botucatu-SP female soccer team with a mean age of 22.1 ± 4.2 years. For laboratory tests , it was evaluated: triglycerides (TG), total cholesterol (TC) and fractions, glucose and gamma-GT were dosed by dry chemistry (Vitros® System, Johnson & Johnson). LDL-cholesterol was obtained by Friedwald formula. Total antioxidant performance (TAP) was obtained by the method of fluorescence assay for the measurement of plasma. Weight, height and body mass index (IMC) were measured, percentage of body fat was obtained by bioeletrical impedance analysis (Biodinâmics, modelo 450, USA). Arterial blood pressure was checked by auscultatory method and cardiorespiratory fitness was determined by ergoespirometric test (Ramp Protocol). Maltodextrin was supplemented (30 g in 400 ml) 30 minutes after M0 with placebo (400 ml) or mate (5 g in 400 ml of water). Statistical analysis: ANOVA for repeated measures followed by Tukey's test set, p<0.05. Results: There was a decrease in the pH after exhaustive testing for water and tea (p<0.0001), the same was observed for bicarbonate (p<0.0001). In both groups pO₂ increased for ...

Influência dos estados emocionais em jogadoras de handebol

Questions of psychological interference have been white of the researchers, that identify in the emotional states, a key precious and important in the fight to get a significant result in the esportivo context. The present study it raised questions of interest of sciences of the sport, objectifying to check the influences of the emotional states of players of handebol and its possible interferences in the esportivo income. We work with a qualitative research, leading given next to the athletes and commission technique of the team of handebol of Sorocaba; using questionnaires structuralized and halfstructuralized for the collection of data. All the gotten results had been represented graphically and analyzed front to the theoretical referencial of the area. These results in had shown them that inside of the searched universe, consequentemente exist some factors that intervene with the esportivo income of the majority of the athletes , affecting in a generalized manner the income of the team. In this way we have that it is not only enough to give attention to the physical training, technician and tacticians. It is necessary to give a special attention to the psychological factors of the athletes, so that in a competition they can relieve everything that that has condition to relieve. Finally, we more suggest deepened research inside of this area so that let us can better understand and take attitudes with regard to subjects as the Daily paymenstrual Tension and the question of the leadership, in the form of case studies. We also suggest an intervention of work of a psychologist of the sport acting next to team since the phase of definition of objectives until the ends of the championship.

Efeitos preventivos do exercício físico sobre as proteínas ciclooxigenase-2 (COX-2) e fator de crescimento de vasos derivado do endotélio (VEGF) no músculo cardíaco em ratos tratados com dexametasona

Dexamethasone (DEXA) is a synthetic glucocorticoid widely used in the handling of several drugs, for its proven benefits in fighting inflammation and allergies. Despite their benefits, their chronic use leads to several side effects that include changes in the body in the metabolism of carbohydrates, lipids and proteins. Moreover, being an anti-inflammatory, acts on the arachidonic acid pathway, reducing the expression of the enzyme cyclooxygenase (COX-2) and growth factor derived from the endothelium of blood vessels (VEGF) in various tissues. However, its effects on the myocardium are still uncertain. The physical training (PT), in turn, promotes effects contrary to those caused by chronic use of DEXA, however, little is known about the preventive effects of TF in the side effects of Dexa in the myocardium. Therefore, the aim of this study was to determine if the TF has the ability to prevent and/or mitigate the effects of Dexa in protein expression of COX-2 and VEGF in the myocardium. Forty animals were divided into 4 groups: sedentary control (SC), sedentary treated with Dexa (SD), trained control (TC) and Trained treated with Dexa (TD) and submitted to a protocol of physical training on the treadmill for 70 days (1 h/day-5 days per week, 60% of physical capacity) or kept sedentary. Over the past 10 days, rats were treated with Dexa (Decadron, 0.5 mg/kg per day, ip) or saline. During training the animals were weighed weekly and during treatment daily. At the end of treatment was made to measure fasting glucose levels of animals. The rats were killed with excess anesthesia and cardiac muscle was removed, weighed, homogenized, centrifuged and stored at -20° C for analysis of protein expression of VEGF and COX-2 by Western blotting technique. Treatment with dexamethasone caused a weight loss of 18% in sedentary animals and 13% in trained as well as elevated levels of fasting glucose in sedentary (88%). The TF was unable to mitigate the loss in...
