Currently the world is under an energy revolution, every day more technologies are developed in order to better use the energy for having better energy efficiency of equipment and processes with minimal environmental degradation. Taking into account that thousands of people live in built environments in the context of cities and that the energy flow to this location is significant, it is important to study the built environment as a potential source of savings, energy recovery and regeneration, because cities are the major bottlenecks energetic. Therefore, this study aimed to examine and to list the most important and promising technologies to be used in the built environment to collect or save energy that would be wasted, such as clothes that generate energy through movement or solar incidence, facades of buildings that generate energy due to solar radiation, fitness centers that produce electricity due to the rotation used in fitness equipment for athletes, elevators that take advantage of the potential energy or use it more rationally, generators that take advantage of energy vibrational, and finally more sustainable vehicles with higher performance and less degrading the environment. The information and results obtained from this study show that the technologies used to harness energy before lost are increasingly evident and also is increased the progress relative to the energy use in a urban context. In the closure, a comparison of energy expenditure between a city that uses some of these sustainable technologies and another of the same size with conventional habits is presented

In the competitive judo, the form as a trainer organizes the process of his/her athlete's training is a very important task for a good acting and a better use of the technical procedures. There is great importance in determining the exercise intensity for the judocas training due to the interest for the high income in several competitions, and few studies returned for this research area, involving those athletes' different physiologic conditions. Therefore, it is necessary to improve protocols of physical evaluation for this modality, increasing his/her applicability. The present study aimed at to verify the validity of a protocol of specific aerobic test of the judo (technique ipon-seoi-nague), no exhausting, adapted of the method of CHASSAIN (1986), using deltas of variations of the lactacidemia and of the Scale of Perception of Effort of Borg, in athletes well. The test adapted to the judo constituted of four exercise series with two efforts similar (double) of 180 seconds with one interval of 90 seconds among them. The series of exercises were accomplished in consecutive days. The intensities of the double tests were of 85%, 95%, 105% and 115% of the minimum lactato for each participant. This work used the technique ipon-seoi-nague, obeying the reasons effort-pause individualized for each athlete, that you/they correspond to the intensities of exercises proposed by the protocol of CHASSAIN (1986). In that way, the athletes applied a blow (maximum speed) and they rested some seconds, depending on the regime effort-pause of the session. At the end of each collection collection of blood (25NL) of each participant's earlobe was accomplished, seeking to measure the concentration of sanguine lactato. The collections were accomplished at the end of the first and of the second efforts, in each one of the series. For the analysis of the Perception of the athletes' Effort, the Scale of Perception...

This descriptive study aimed to investigate what changes of emotional states more sensitive to internal and external influences and to investigate the motivating factors and stressors in basketball players of a Regional Championship of the Interior . Study subjects were 56 (fifty - six) athletes, members of 05 (five) highest ranked teams in the competition. As a measuring tool used the Frester ‟sP sychicLoad Test (1972, apud SAMULSKI, CHAGAS, 1992) . Data analys used descriptive statistics. The findings showed that the facts considered as motivators during the competition were: the audience, the fact of constantly thinking on achieving the desirable aims, and the establishment of very high aims; the stressful factors were: disagreements and conflicts with the coach, partners or family, bad sleeping the night before the competition, excessive nervousness and to be prejudiced by the referees . Therefore, we can conclude: the facts that influence the interest can be of motivating or stressful order , depending on the personal and situational perception; most athletes characterized the competiti ve sport as more stressful than motivating, and this assessment influenced by constant pressure of intrinsic and extrinsic factors that athletes suffers during the competitive environment

Currently in the sports world, one of the prerequisites imposed by the organizers of sports sieves (selection of athletes) is the height, it becomes increasingly essential to play in clubs and teams worldwide. We noticed that teams base categories also suffer greatly from this height limitation. The objective of this research is to investigate the opinion of coaches, former coaches, players and former players and basketball players and volleyball on that possibility, or what to think about creating sub 1.80 m championships in men's tournaments. . This is a study of the qualitative and descriptive conducted with athletes and coaches volleyball and basketball courts, 6 volleyball players, six basketball players, volleyball players and a coach second technical basketball. We had the result of this work three main parameters: If athletes and coaches are in favor or not the creation of leagues, if there is any form of prejudice with the low in basketball and volleyball and opinions about the players lower in basketball and volleyball. Small players adhered to the idea of creating the league, high players were divided in high response and the coaches agreed saying that it grows with the Sports. Next step is the implementation, planning for these championships to assess the real possibilities of success of this initiative.

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.

there is evidence that sport can trigger the onset of postural patterns specific to each modality, regardless of the geopolitical aspects, social, cultural habits of everyday life and ethnicity. Since changes in flexibility are cited as possible precursors of decreased range of motion, thereby harming the mechanics of the lower limbs and gait. Objetcive: The objective of this study was to analyze changes in posture and flexibility in young soccer players. Methods: were assessed 51 youngsters, aged between 14 and 18 years, soccer players registered in the Municipal Presidente Prudente SP and categories of the base of Gremio of Presidente Prudente. Data were collected from the assessment by the postural software assessment, and flexibility tests the Bench, to jail and later by tests of muscle length to jail earlier proposed by Kendall et al , was also collected anthropometric data were later confronted with the results statistically. The results were organized into spreadsheets for computing, which later could be performed the statistical analysis. Values are expressed by means of central tendency and variability as well as medians and 95% confidence intervals. The comparison for each profile height and BMI was made by means of analysis of variance complemented by Tukey test. Were considered the statistical differences when P <0.05. Results: In the sample studied 64% of the subjects classified as normal posture, the same happened with 70.59% of the athletes for flexibility in relation to the center of gravity of the sample had 100% anterior displacement of the trunk and 86.28% with a deviation of center of gravity to the left, showing a tendency to some postural deviations for the group assessed. Conclusion: from the results we can conclude that there was significant relationship between the postural angle of the right leg and left angle of the pelvis with BMI and also ankle angle...

The objective of this study is verify the occurrence of bullying in soccer and if this phenomenon can be considered a possible cause of the abandonment of this sport. The sample consisted of 143 male athletes, aged between 15 and 18 years old, all of whom competed in the Copa São Paulo de Futebol Júnior in 2011. The results show that most athletes have practiced, suffered and observed bullying in soccer, but the minority has fear of being assaulted on the team and few thought to stop playing because of this social phenomenon. It is suggested that more studies be conducted in this area and that the sport psychologist and coach provide to the team a better living and training structure, and the athletes should be united, avoid jokes that exceeding the limits offending another member of the group and make everyone feel comfortable in that place, not influencing the individual or collective performance

It is possible in many countries, perhaps all, there is business groups of pharmaceuticals industry, cosmetics together with the universities that use animals in scientific research and testing for the creation of new products and medicines. Currently is growing discussion about standards and criteria for the use of these animals (guinea pigs) and also increases the number of debates on ethical issues in research with animal models. This research seeks to portray the reality of the use of animals in scientific research academic at the University, specifically to research in physical education, as it has used animals in the areas of Physiology of Sport and Physical Activity, Nutrition for Athletes, among others. Initially is shown the pre-reflection, exposing the laws governing the subject, treating the animal experimentation with regard to its history and the issues of speciesism and the methodological mistake. It reveals what it is and as is the use of animals in education and the inability of the student to change that reality, to refuse to participate in the cruel activity, and even they are aware of their rights as in the case of the withdrawal of consciousness. Presents researchers and universities not use animals and ends the pre-debate showing Who is really the most animal research at the university by providing alternatives for them. We conducted a literature survey on animal experimentation, research universities, and alternative methods. The following is the phenomenon in understanding and awareness of the researchers who use animals in their research, conducting a phenomenological analysis of his speeches, revealing the meanings of their animal research. The focus of this study is, therefore, the analysis of discourses of researchers who carried out research using animal experiments (guinea pigs). The phenomenon of understanding of the researchers about their research is made clear... (Complete abstract click ectronic access below)

Voleyball is a sport that has gained an important contingent of public, achieving a growing visibility especially in recent years. Despite being a very democratic sport, as it is practiced by both men and women, it can be observed that there are differences when the analysis refers to who is in charge of the teams. So the purpose of this study was to analyze the presence of women in the country volleyball (coaches) from base categories to the professional adult, through a documental research. Data were collected from electronic documents, official websites and websites of federations teams. The results indicated that the number of women coaching volleyball athletes is minimal, revealing the difference between the professional treatment given to male and female genders. Therefore, it became clear that certain discrepancies are caused not only by lack of professionalism, but also by the cultural characteristics that still consider the place of women as domestic and not in the command of field sports

Muscle fatigue is described as a cause of injuries among the many related to the running practice. Therefore, the purpose of this study was to analyze the behavior of the amplitude (RMS) and median frequency (MF) of EMG signal of the iliocostalis (CI), rectus femoris (RF), vastus lateralis (VL), vastus medialis (VM) biceps femoris (long head) (BFCL), tibialis anterior (TA) and gastrocnemius (lateral) (LNG) from the right lower limb, and the behavior of the parameters of amplitude (AP) and frequency (PF) spent in different percentages of the maximum speed during incremental protocol of treadmill running. 10 volunteers participated in this study, athletes, male, aged between 18 and 30 years with no history of injury in lower limbs and similar anthropometry. The protocol consisted of a treadmill test with initial velocity of 10 km.h-¹ and increments of 1 km.h-¹ each three minutes until volitional exhaustion, without rest interval. Synchronized collections were made of electromyographic and kinematic data. The signals were obtained through an acquisition module of biological signals (Telemyo 900 - Noraxon - USA) and software (Myoresearch - Noraxon - USA) calibrated with a sampling frequency of 1000 Hz, gain 2000 times. The raw data were filtered with a 60Hz notch filter, high pass and low pass 20Hz to 500Hz. To capture the image was used a digital video recorder (model NV-GS320, PANASONIC brand), and for image scanning and kinematic data collection was used the software Peak Motus 9.0 (ViconPeak). To obtain the values of RMS and FM analyzed the last ten passes of each speed through a specific routine (Matlab). To obtain these variables AP (m) and FP (stride I min) were analyzed for the last ten past each speed, using specific software (Peak Motus 9.0). After verification of data normality (Shapiro-Wilk) and homogeneity of the data (Levene), the comparison ...(Complete abstract click electronic access below)

One of the main causes of incapacity in athletes, be they human or equines, is the occurrence of intra-articular lesions. The equines are each time more required in his athletic performance, resulting in intense stress to the structures that composes the locomotor device. The leading cause of human and equine athlete’s functional incapacity is the intra-articular disorders. One of the greatest advances in sports medicine was the development of arthroscopy as a minimal invasive intra-articular surgery. The defining characteristic of diagnostic or surgical arthroscopy is featured by minimal tissue damage and broad inspection of internal structures inside the joint associated with low morbidity and complications. The advantages of surgical arthroscopy over traditional surgery are well known: limited hospitalization, early return to competition, lower risks of post-operative joint rigidity, magnification of inspected structures, joint lavage associated or not with removal of potentially dangerous substances. Arthroscopy cannot replace conventional methods and must not do so; however, the intrinsic limitations of conventional diagnostic techniques, such as radiology and synovial fluid analysis, must be kept in mind, particularly in evaluating damage to cartilage and the synovial membrane. Arthroscopy has now become the accepted method of performing all joint surgery, however it is mainly used for radical surgery, such as osteochondral fragment removal, surgical curettage and arthroplasty

Volleyball is a sport in which the laterality dominant limb shows superior strength and coordination because of its preferential use. Asymmetrical tendencies during the landing after the jump when striking or blocking actions are predominant for most part of game (ARRUDA; EDUARDO, 2008). Adaptations include imbalance of forces in static and dynamic motions at the knee joint, which increases risk for injury. Also, asymmetries in balance control during jumping and landing associate with a general postural instability that can be observed during static balance tasks. The purpose of this study was to investigate relationship between unequal lower limb strength (muscle imbalance) and postural stability levels in volleyball athletes and non-athletes. Nine female volleyball athletes and 10 active non-athletes participated in this study. Four encouters with participants were scheduled: three encounters in the bodybuilding gymnasium to collect anthropometric measures (weight, height for BMI, thigh circumference, which provided an initial diagnosis about asymmetry), and to perform the isometric strength test (i.e., leg press using a load cell and a force transducer to calculate uni an bilateral strength). The last encounter was in the laboratory where a balance test on a force platform was administered under five test conditions, with three repetitions each: baseline (natural standing position), one-leg standing, right side, with full vision (D_CV), and blindfolded (D_SV), one-leg standing, left side, with full vision (E_CV), and blindfolded (E_SV). The stability levels were evaluated using the path length parameters which was based on the total displacement of the center of pressure (DTCP). . Both groups shows asymmetric strength levels between legs, with better performance for the right leg. An ANOVA three way using the DTCP for the CV condition, legs (D x E), trials (3) with repeated measures for the first two factors and with a between (three)...

Examine the phenomenon of bullying behavior that makes people teased, laughter, sarcasm, irony, among other types of attacks. This is not only physically, but with moral violence, emotional or psychological. When there is an effective intervention against bullying, all individuals in the group start to suffer with this situation, which can lead to psychological disorders, hampering the progress of relations as well as team sports, over a period of training and competition. This article analyzed a sample of athletes in order to find behaviors that characterize the extent of bullying and can see the consequences of it, as early drop out. Through the results it was concluded that the actions that characterize bullying are present in very high performance football and may even lead to drop out the sport. We also evaluate the environments frequented by teams can become enhancers of this phenomenon, they are times when athletes have a living space and one that may become amenable to the events, plus the fact that many athletes have already thought about leaving the sport because to bullying
