Avaliação goniométrica da amplitude de movimento do ombro de crianças praticantes de beisebol

Introduction: Baseball is a Sport disputed by two teams composed at least by nine players which compete between themselves in a game of six innings in the amateur game, for children up to 10 years old. Objective: The objective is to compare the movement degrees of the shoulder joint between the dominant and the non dominant shoulder. Methods: Eleven male subjects were assessed (8,63 ± 0,67 years old) whom practiced baseball at the Nikkey Club of the city of Marília – SP. All of the subjects were assessed by the same examiner, whom measured the range of motion (ROM) of both glenohumeral joint. The Student t test was used for the comparison of the shoulders, with level of significance of 5% (p≤0,05). Results: The subjects presented significant differences on the external rotation movement (p= 0,014) between the dominant shoulder (63,63 ± 12,92°) and the non dominant shoulder (55,45 ± 16,27°), and in the internal rotation movement (p= 0,001) between the dominant shoulder (32,90 ± 5,68°) and the non dominant shoulder (40,72 ± 5,74°). Conclusion: The results obtained in this study, on the experimental conditions utilized, allow us to conclude that the practice of baseball influence the range of motion of external rotation and internal rotation of the dominant shoulder, with increased external rotation, and a decreased internal rotation, provoking instability of the shoulder joint.

Equilíbrio muscular e pico de torque após jogo de futsal

Indoor soccer is a modality of sport similar to football, which is accompanying an increasing of the number of participants. With the growth of this sport, increased as well the number of injuries, which has been requiring greater attention and care from the health professionals. AIMS: To investigate the functional balance before and after an indoor soccer game and analyze the maximum force before and after the game, in order to verify if there is a great loss of muscle strength of knee flexors and extensors during the game. METHODS: The study included seven amateur soccer players. The isokinetic evaluation was made using the Biodex 3 isokinetic dynamometer at velocities of 60°/s and 180°/s with five repetitions at each velocity for each leg. Further, the study analyzed the peak torque of each leg at each speed of the extensor muscles and flexor concentric and eccentric. RESULTS: Compared to the peak torque before and after the game, there were no significant differences. At 60°/s in the non-dominant leg, peak torque decreased after the game of the extensor concentric and eccentric. In the dominant leg there was a decrease of peak torque in eccentric flexion at 60°/s and concentric flexion to 180°/s. Comparing the peak torque between dominance, there was any significant differences in speed. However, in eccentric flexion at 60°/s before the match there was a significant difference. The peak torque of the dominant leg showed better results than the non-dominant leg. Regarding the functional balance there was no statistically significant differences between the muscles involved. CONCLUSION: From the results achieved, it is possible to conclude that the peak torque of flexor eccentric decreases depending on the length of the exercise. This muscle is stronger in the dominant leg, comparing to the non-dominant leg

Construção de instrumentos técnicos de astronomia para a divulgação científica: telescópio fotométrico de grande abertura e baixo custo

Although the popularization of astronomy in the last decade and the International Year of Astronomy, celebrated in 2009, there's a great lack in respect of quality instruments for astronomical disclosure. Thinking in this research about it, we intend to recuperate and elucidate a technique long forgotten: the metal mirror amateur telescope, once was done in the first reflecting telescopes. However, with the resources available today and given the high purity of the materials, our results were better than that obtained by the pioneers. We developed and built a large aperture telescope (250 mm diameter) and very bright (focal ratio = 4.0), versatile and portable. In our study was described step by step the process to fabricate the telescope. Through its first images captured of the Moon, we can illustrate its versatility both for use in outreach events and for use in amateur astronomy, because it is a primary focus capture system and can run registration of various astronomical events

Estratégias de enfrentamento em jogadores de futebol

The aim of this study was to identify scores of interest related to coping strategies used by professional and amateur football players. Participants were 134 male football players, 71 professionals (age=22,77±3,98 years) and 63 amateurs (age=17,18±0,84) from three teams participating on the First Division State Championship). The players answered individually to the Coping with Problems Scale. Significance level was P<0.05. When coping strategies were compared based on game position and player category (professional or amateur), lateral player amateurs used more wishful thinking /religious practices (P=0.042) than professionals. Coping Focused Problem was the most used strategy used by both the professionals and amateurs, except the amateur laterais, who used more wishful thinking /religious practices.

Aproximações entre as comunidades científica, amadora e escolar: estudando as potencialidades de observatórios astronômicos para a educação em astronomia

This article considers some potential of activities developed in non-formal education in astronomy, like astronomical observatories and other related establishments. This kind of research is less explored in our country. We present, in this text, a model to study possible relations among these kinds of communities: the scientific, the amateur and the professional, applicable in astronomical observatories, in a motion against the local and punctual activities dispersion and pulverization of these establishments, and against the use of common sense to develop their activities, aiming the advancement of the astronomy education and its national research.

Entre os muros da escola: o saber experiencial emergente nas aulas de educação física da periferia

This study aimed to analyze the teachers´ knowledge of a physical education teacher network state of São Paulo. The interviewed reported having problems regarding the use of the court, especially because there is invasion of the community to smoking marijuana and/ou playing football, revealing the predominance of experiential knowledge to work in a new school, whose location and local culture do not seem to prioritize this social space as learning, dissemination and preservation of other bodily manifestations of the process of human civilization. It was found in such a setting an imbalance of the relative strengths of power between teacher and students, from schools, football and drugs in relation to body movement culture, it being understood that the relationships between these individuals are interdependent and dynamic. Finally, it urges an integrated process in educational, family, social and political fields from the perspective of balancing forces in relation to the use of that space, providing conditions for teaching and propagation of content (games, sports, gymnastics, dances and fights) of the body movement culture.

Os álbuns fotojornalísticos online e a construção do acontecimento: atribuições de sentido a partir da composição imagética dos protestos de junho

Given that the choices involved in the selection of compositional techniques in photography are mediated by values, this article aims to analyze the compositional techniques of photographs published by photojournalistic online albums during the protests of June 2013 in Brazil. These albums feature professional and amateur photographs considered "the best" of this event and, interestingly, the chosen photographs have several composition techniques in common. We will examine these images from the perspective of significant effects that these techniques engender with the objective of examining the meanings that were attributed to that event in those albums.

Evaluation of the best-designed graded exercise test to assess peak treadmill speed

This study examined the influence of different speed increments during treadmill exercise tests on peak treadmill speed (Vpeak) and its relationship with a 1-h treadmill running performance. 18 male recreational and amateur runners (10-km running pace: 10–15 km·h−1) performed, in an alternate order, 3 continuous incremental exercise tests with different speed increments (0.5, 1.0 and 2.0 km·h−1) on a motorized treadmill to determine Vpeak. Thereafter they undertook a 1-h time trial on a treadmill. Vpeak was determined as either (a) the highest speed that could be maintained for a complete minute (Vpeak-60 s), (b) the speed of the last complete stage (Vpeak-C), or (c) the speed of the last complete stage added to the product of the speed increment and the completed fraction of the incomplete stage (Vpeak-P). The Vpeak values were highly influenced by the different speed-incremented rates and the Vpeak-P determined during the protocol comprising speed increments of 1 km·h−1 presented the highest correlation with 1-h time trial performance (r=0.89). The results suggest that a protocol with speed increments comprising 1 km·h−1 and with a 3-min stage duration should be used as standard for the determination of Vpeak to assess aerobic fitness and predict endurance performance in recreational runners. Furthermore, the Vpeak-P should be used for the determination of Vpeak.

Dominant-non-dominant asymmetry of kicking a stationary and rolling ball in a futsal context

The aim of this study was to analyse the characteristics of the asymmetries in the dominant and non-dominant limbs when kicking stationary and rolling balls. Ten experienced Brazilian amateur futsal players participated in this study. Each participant performed kicks under two conditions (stationary ball vs. rolling ball) with the dominant and non-dominant limbs (five kicks per condition per limb). We analysed the kicking accuracy, ball and foot velocities, angular joint displacement and velocity. The asymmetry between the dominant and non-dominant limbs was analysed by symmetry index and two-way repeated measures ANOVA. The results did not reveal any interaction between the condition and limb for ball velocity, foot velocity and accuracy. However, kicking with the dominant limb in both kicks showed higher ball velocity (stationary ball: dominant - 24.27 ± 2.21 m · s(-1) and non-dominant - 21.62 ± 2.26 m · s(-1); rolling ball: dominant - 23.88 ± 2.71 m · s(-1) and non-dominant - 21.42 ± 2.25 m · s(-1)), foot velocity (stationary ball: dominant - 17.61 ± 1.87 m · s(-1) and non-dominant - 15.58 ± 2.69 m · s(-1); rolling ball: dominant - 17.25 ± 2.26 m · s(-1) and non-dominant - 14.77 ± 2.35 m · s(-1)) and accuracy (stationary ball: dominant - 1.17 ± 0.84 m and non-dominant - 1.56 ± 1.30 m; rolling ball: dominant - 1.31 ± 0.91 m and non-dominant - 1.97 ± 1.44 m). In addition, the angular joint adjustments were dependent on the limb in both kicks (the kicks with non-dominant limb showed lower hip external rotation than the kicks with the dominant limb), indicating that the hip joint is important in kick performance. In conclusion, the kicks with the non-dominant limb showed different angular adjustments in comparison to kicks with the dominant limb. In addition, kicking a rolling ball with the non-dominant limb showed higher asymmetry for accuracy, indicating that complex kicks are more asymmetric.

Doping e suplementação no MMA: um estudo documental de caso

The first records of the use of substances that enhance athletic performance began in antiquity. The objective of this study is to analyze the use of doping methods and supplements by amateur athletes and MMA professionals and what motivates usage. The work consisted of desk research in which use of work carried out at fifteen amateur and professional athletes, which underwent a data collection; these athletes are all over eighteen years old, male and practicing MMA for at least two years. The questionnaire that they were submitted corresponded to ten multiple-choice questions, which are: Age, what type of fight practiced as a basis for MMA, how long practices martial arts, sees the sport of competitive or recreational way, has already made use dietary supplements, have made use of banned substances (steroids) in the sport, it has already made use of steroids which the substance used and to what end was done using, know the side effects of anabolic steroids, know one or more people who have already made use of steroids in order to increase their performance in the fight, he believes it is possible an athlete achieve success in modern MMA without the use of anabolic steroids. The results showed that, of the fifteen athletes interviewed, only two said they never made use of dietary supplements, and four said they have already made use of anabolic steroids. All fifteen athletes claim to know the side effects of steroid use, and 14 of them say they know one or more sport-mates who have already made use of steroids. Given the results, it can be concluded that the use of steroids is common in MMA
