Análise da cinética de remoção de lactato em atletas de canoagem slalom

The aim of this study was to verify the kinetics of lactate production and removal in slalom kayak athletes, K1 category, during official competition. Eight male athletes (22,6 ± 4,3 years) participated of the study. For the analysis of lactate, 25µL of capillary blood were collected. The kinetics of lactate removal was performed before the warm-up (Pre), just after the competitors exit from the river (Post 0'), 5 (Post 5'), and 20 (Post 20') minutes. The results demonstrated a significant increase in lactate concentrations (9.8 mmol/l, 9.4 mmol/l and 6.6 mmol/l) at 0', 5' and 20' post respectively, with values of P<0.01. The findings indicate that after 20 minutes the values of lactate reduced significantly (P<0.05) compared to Pre exercise, suggesting that the athletes would indicate good metabolic conditions for the second turn of the race.

Componente lento da cinética do VO2: determinantes fisiológicos e implicações para o desempenho em exercícios aeróbios

A cinética do consumo de oxigênio (VO2) e a resposta do lactato sanguíneo durante o exercício de carga constante em diferentes intensidades permitem caracterizar os domínios moderado, pesado e severo do exercício. Em exercício de intensidade constante, o perfil da resposta do VO2, analisada por ajustes exponenciais, apresenta as fases cardiodinâmica, fundamental e lenta. A ocorrência do componente lento (CL) tem sido associada a fatores como recrutamento de fibras do tipo II e acúmulo de metabólitos, como lactato, íons H+, fosfato inorgânico e ADP. O CL expressa uma redução da eficiência muscular e tem sido associado à menor tolerância de exercícios aeróbios de intensidade alta. O presente estudo teve por objetivo detalhar a fundamentação teórica sobre sua ocorrência, a influência na tolerância ao exercício, bem como prover os diferentes procedimentos adotados em sua quantificação.

Differential effects of variation in athletes training on myocardial morphophysiological adaptation in men: Focus on I-123-MIBG assessed myocardial sympathetic activity

High intensity systematic physical training leads to myocardial morphophysiological adaptations. The goal of this study was to investigate if differences in training were correlated with differences in cardiac sympathetic activity.58 males (19-47 years), were divided into three groups: strength group (SG), (20 bodybuilders), endurance group (EG), (20 endurance athletes), and a control group (CG) comprising 18 healthy non-athletes. Cardiac sympathetic innervation was assessed by planar myocardial I-123-metaiodobenzylguanidine scintigraphy using the early and late heart to mediastinal (H/M) ratio, and washout rate (WR).Left ventricular mass index was significantly higher both in SG (P < .001) and EG (P = .001) compared to CG without a statistical significant difference between SG and EG (P = .417). The relative wall thickness was significantly higher in SG compared to CG (P < .001). Both left ventricular ejection fraction and the peak filling rate showed no significant difference between the groups. Resting heart rate was significantly lower in EG compared to CG (P = .006) and SG (P = .002). The late H/M ratio in CG was significantly higher compared to the late H/M for SG (P = .003) and EG (P = .004). However, WR showed no difference between the groups. There was no significant correlation between the parameters of myocardial sympathetic innervation and parameters of left ventricular function.Strength training resulted in a significant increase in cardiac dimensions. Both strength and endurance training seem to cause a reduction in myocardial sympathetic drive. However, myocardial morphological and functional adaptations to training were not correlated with myocardial sympathetic activity.

Correlações entre parâmetros aeróbios e desempenho em esforços intermitentes de alta intensidade

The purpose of the study was to examine the relationships between intermittent high-intensity efforts (RAST) parameters and variables related to aerobic metabolism (anaerobic threshold; LAN, maximal oxygen uptake; VO2MAX and velocity correspondent to VO2MAX; iVO(2MAX)). Eight under-17 (U17) soccer players (16 +/- 1 years) participated in the study. The participants were submitted to a graded exercise test and six maximal sprints of 35m with 10 seconds of passive recovery between each effort (RAST). The RAST parameters were not significant correlated with VO2MAX and LAN. However absolute and relative mean power were significantly correlated with iVO(2MAX) (r=0.79 e r=0.85, respectively). Furthermore, the fatigue index and the relative peak power were significantly correlated with the iVO(2MAX) (r=-0,57 e r=0,73, respectively). In conclusion, the only aerobic variable correlated with performance in consecutive efforts with brief recovery periods, such as RAST, is iVO(2MAX).

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)

Iluminação de exteriores utilizando tecnologia LED: estudo de caso

This Graduate Work aims to exhibit the analyze of the applicability of LED technology in a real outdoor lighting situation, and this project’s illumination solution is compared with the initial proposal, the sodium vapor lamps. What is studied is an outdoor area, like the roads and parking lots of a plant. A light planning software is used for this comparison, and the results are displayed instantly, allowing rapid analysis of the project through a simulation. The medium illuminance is the same in both solutions for this case study and minimum rates set as standard were observed then the analysis are appropriate in this project. Various aspects are considered in order to obtain a comprehensive analysis of this project, such as economic, environmental and quality of lighting. LED technology in outdoor lighting is presented in its infancy, but promising. Solid state lamps show great advantages when compared with other technologies, such as discharge lamps, however there are some disadvantages tied to new products that are expected to be overcome with technological development and increased production
