title: Analysis of competitive behavior in young and adult handball athletes

description: Abstract This study aims to analyze the competitive behavior of young and adult handball athletes. Evaluated 143 young athletes (16.1 ± 0.7 years) of both sexes, participants of the Youth School Games, and 69 athletes (24.0 ± 4.3 years), all male participants of the Pan American club championship in the year 2009. To assess the competitive behavior we used the Sport Orientation Questionnaire instrument with subscales: compete (TQ1), win (TQ2) and set goals (TQ3). For data analysis descriptive statistics and the Mann-Whitney test were used, considering 5% of significance. Both young and adult athletes reported greater importance to the TQ3 domain. Comparing the groups, only the TQ3 domain did not show statistically significant difference with higher values for adult athletes. Thus, we can conclude that school and performance athletes showed similar competitive behavior, that is, there is a high tendency in the perception of victory in the competitive process, regardless differences of age and practice time. However, in both groups it was observed a greater emphasis on setting goals, and the performance athletes reported greater importance to the TQ3 compared to the young ones - 8.0 and 9.0, respectively.

title: Sports talents in judo and swimming

description: Abstract This paper purported to establish the existence of a system for the development of talented Brazilian athletes judo and swimmers, as well as to describe how coaches in both sports see this process occurring in practical terms. An exploratory and descriptive research was conducted by means of interviews with 18 high-performance coaches (11 swimming coaches and 7 judo coaches). The participating coaches answered to 10 semi-structured questions concerning the development of sports talents in Brazil. The polled results were analyzed through the “Discourse of the Collective Subject” (DCS) method. According to 77% of those coaches, there is no established national guidelines for the development of talents in either one of these sports categories, and 66% of the interviewed stated that the development of the athletes falls entirely to each sporting association they belong with. The opinions of the interviewed coaches indicate that the government offi ces in charge of sports administration produce no comprehensible national guidelines for judo and swimming in Brazil, which leaves to institutions such as Sports Clubs, Associations and Municipal Sports Authorities the full responsibility for the development of athletes in both categories.

title: Parental support in sports development of Brazilian gymnasts participants in the Olympic Games (1980-2004)

description: Abstract Sports development involves important aspects that collaborate towards the achievement of a high level sports performance. Parental support is one such fact to be considered in Long Term Athlete Development (LTAD), capable of benefiting or harming athletes if not adequately administered. This study registers and discusses the importance of parental support in female Artistic Gymnastics, from the perspective of Brazilian gymnasts who have participated in the Olympic Games. The method used was Oral History with the technique known as oral testimony. The participants of the study were the ten Brazilian gymnasts who represented Brazil in the Olympic Games from when the country first participated in this championship, in 1980, up to the best Brazilian classification in Athens (2004), totaling ten gymnasts (a sample comprising 100% or the research universe). Testimony analysis was conducted through crossanalysis. The study shows unanimity among the gymnasts in regards to the importance of parental support in the sports development process. In addition to reinforcing the results found in the literature, the testimonies provide details of the relationships between the gymnasts and their families for deeper reflections around the subject, a distinguishing feature of studies with oral testimonies.

title: Do Code of Points in men artistic gymnastics and women artistic gymnastics favor asymmetric elements?

description: Abstract The purpose of research was to determine whether Code of Point (COP) in Men Artistic Gymnastics (MAG) and Women Artistic Gymnastics (WAG) favor asymmetric elements in order to build gymnast’s competition exercise. All elements which are described in MAG (N = 993) and WAG (N = 713) COP were included and defined if they are symmetric at start position, during movement and at final position. Element is symmetric by arms and trunk with legs activity when all left and right body side performs simultaneously same activity. Results show in MAG COP as a whole is significantly more asymmetric elements with asymmetric trunk and legs activity. In WAG COP as a whole is significantly more asymmetric elements with asymmetric activity of arms, trunk and legs. Hypothetical most difficulty exercises on each apparatus revealed that in general for all around gymnast proportion between asymmetric and symmetric elements is close to 70% to 30%, what suggests that difficulty relates to increased asymmetry. COP in MAG and WAG enforces asymmetric movements for achieving high results, however, coaches’ task is to be aware of COP influence on gymnasts’ health and minimize asymmetries in load and to work on symmetric conditioning.

title: Promotion of physical activity, healthy eating and family health in municipalities with health gym

description: Abstract The present study aimed at: 1) describing the prevalence of actions to promote physical activity and healthy eating and describing the characteristics of family health strategies in Brazilian municipalities funded to implement the “Health Gym Program”; and 2) verifying the prevalence of these actions according to the presence of Family Health Support Centers (FHSC) and the presence of physical education professionals and nutritionists in the health family teams. We conducted telephone interviews with public health managers in 2012 in all cities funded to implement the “Health Gym Program”. We described the frequencies (%) of the family health teams’ characteristics and of the physical activity and healthy eating actions, and we calculated the prevalence in municipalities with and without FHSC, and in municipalities with and without physical education professionals and nutritionists in the teams. We used the chi-square test to evaluate the associations. Out of a total of 5,570 municipalities in Brazil in 2012, 2,074 (37.2%) were funded to implement the program, and amongst them, 44.1% (n = 914 public health managers) participated in the survey. Most of the municipalities did not have FHSC teams (61.5%), though reported developing physical activity (84.1%) or healthy eating actions (83.9%). The education sector was referred to as a public partner in most actions. The prevalence of physical activity (91.5%, p &lt; 0.001) and healthy eating (88.2%, p = 0.006) actions was higher in cities with FHSC than in their counterparts. The prevalence of primary care actions was higher in municipalities that had physical education professionals and nutritionists in teams. Having FHSC with physical education professionals and nutritionists is an important factor for promoting physical activity and healthy eating.

title: How do gender and education interact in physical inactivity patterns in different domains among adults?

description: Abstract The aim of the study was to identify interactions between gender and education on the prevalence of physical inactivity in different domains (commuting, household, leisure and work) among adults of Florianopolis, Brazil. Data were collected from September/2009 to January/2010 with individuals 20-59 years old. This was a cross-sectional population-based study, and physical inactivity in each domain was defined as non-participation in specific physical activities, using a validated Brazilian questionnaire administered by face to face interviews. We interviewed 1720 adults. In men, the prevalence of physical inactivity was higher than among women in commuting (56.9% versus 44.5%; p &lt; 0.001, respectively) and at home (79.0% versus 40.4%; p &lt; 0.001, respectively). In leisure, physical inactivity was higher among women (58.1% versus 45.5%; p &lt; 0.001). Interactions between gender and education were statistically significant in commuting (p = 0.004), household (p &lt; 0.001) and leisure (p = 0.04). Men were more inactive than women from five to eight years of schooling. Household physical inactivity was higher among men at all levels of education, with a reduction in the magnitude of the percentage differences between the genders, with increasing of education. In leisure, women were more inactive than men since nine years of study. Different interactions between gender and schooling were observed according to the patterns of physical inactivity in different domains.

title: Analysis of sport organization and structure of swimming in São Paulo State

description: Abstract The aim of this research is to analyze the organizational structure for high level swimming in the State of Sao Paulo. To achieve this goal a semi-structured interview was performed with eleven elite swimming coaches of the State of São Paulo, and two officials of the Paulista Aquatic Federation. The results were analyzed through Group Character Speech Method (GCS). It was verified that the clubs and Municipal Entities of Sports Practices are responsible for sports training for grassroots and elite athletes. The action's and policies administration for the development of high level swimming in the State of São Paulo does not happen in a centralized way through national organizations such as the COB or the Ministry of Sports, as well as any specific organization, such as FAP or CBDA. The actions and policies management for the development of elite athletes in swimming are responsibility of clubs and Municipal Sports Practices Entities on an individual form, like the definition of guidelines, application of financial resources, accountability, audits and relationships with sponsors.

title: Replication data for: Markups and Firm-Level Export Status

description: In this paper, we develop a method to estimate markups using plant-level production data. Our approach relies on cost-minimizing producers and the existence of at least one variable input of production. The suggested empirical framework relies on the estimation of a production function and provides estimates of plant-level markups without specifying how firms compete in the product market. We rely on our method to explore the relationship between markups and export behavior. We find that markups are estimated significantly higher when controlling for unobserved productivity; that exporters charge, on average, higher markups and that markups increase upon export entry.

title: The representation of Physical Education in the 18th season of a TV series called "Malhação"

description: This research focuses on the professional image of physical education on TV series considering the reputation it has acquired over the past few years. The study aims at investigating some meanings given for Physical Education classes in the eighteenth season of "Malhação". The method used was Discourse Analysis. The results showed that the classes were built based on different sports for boys and girls, focusing on technical execution of the movements. Also, the difficulty of the teacher to deal with issues beyond technical approaches was noticed. The casting of an old man to play the role of a physical education teacher could be considered an interesting and original matter; however, it did not remain in the following seasons.

title: Reasons for dropout of the practice of artistic gymnastics in the extracurricular context

description: Abstract Sport is the main option for physical activity among children and youth. Despite the great interest of this group with regard to sports practices, the literature indicates a high dropout rate. Motivated by this conjuncture, the objective of this study was to verify the reason for dropout, more specifically, in Women Artistic Gymnastics (WAG) within the context of extracurricular activities. We interviewed practitioners of WAG who have a record regarding withdraw of this sport for a certain period of time. For the data treatment, the content analysis proposed by BARDIN was chosen. We found that intrinsic and extrinsic factors are linked to the process of dropout of this sport. However, the extrinsic factors overlapped those intrinsic, evidencing that the environment and situational and interpersonal conditions exert greater influence on the withdrawing of the gymnasts. Thus, we emphasize the importance of the coaches’ attention to these aspects in order to ensure that activities meet the needs and desires of gymnasts.

title: Effects of the alternance between aerobic and resistance exercise in different concurrent exercise sessions on blood pressure responses of healthy adults: a controlled and randomized study

description: Abstract Aerobic exercise (AE) and resistance exercise (RE) have shown benefits in preventing and / or controlling blood pressure (BP), although the influences of these two models (concurrent exercise) in a single session of exercise on BP are still unknown to the individual. Therefore, the aim of the present study was to verify the effects of the alternating between AE and RE in different concurrent exercise sessions on BP responses. In order to do so, ten young male athletes (22.6 ± 3.78 years, 70.3 ± 5.89 kg, 175.96 ± 5.83 cm, 6.8 ± 2.38 % body fat) participated in the study. The tests consisted of four randomized protocols, the sessions consisted of AE followed by RE (AR), RE followed by AE (RA), circuit (CC) (ER and EA alternating intermittently) and control session (CO) (without exercise). AE was performed on a treadmill at 90% of indirect minimum lactate and RE was performed on a circuit at 90% of 12 RM, alternating muscle segments in six exercises. BP was measured in all protocols and post-exercise recovery period (PERP) every 15 minutes during one hour. Results showed a significant decrease in systolic blood pressure (SBP) at the 45th minute of recovery (R45) and one-hour mean values of the PERP in the RA protocol when compared to its value at rest. Diastolic and mean BP showed no significant differences. Thus, the RA session promoted a more accentuated decrease in SBP when compared to the other sessions.

title: Multilevel modeling and mixed longitudinal design in the research in Physical Education and Sport Medicine

description: The main aim of this study was to introduce the use of multilevel modeling in the data from a mixed longitudinal study concerning growth, development and health of Portuguese adolescents. The sample comprises 5155 subjects from 4 age cohorts: 10 to 12, 12 to 14, 14 to 16 and 16 to 18 years. Variables chosen for analysis were handgrip strength and percentage of total body fat. Multilevel modeling analysis showed a quadratic trajectory of adolescents' handgrip strength performance, with higher annual increasing in boys. The percentage of total body fat was positively associated with the static strength and there were marked interindividual differences. The use of a mixed longitudinal design allowed a faster data collection process; in addition, multilevel modeling analysis was sufficiently flexible and robust to accommodate, in a single model, aspects of individual and interindividual changes in static strength development over the time.

title: Agreement and correlation among three different methods for the quantification of the vertical jump height

description: The purpose of the present study was to analyze the association and the agreement among three different methods to quantify of the vertical jump height: abalakov belt (AB), contact mat (TC) and videogrammetry (VG). Thirteen female volleyball players performed three maximal countermovement jumps, without the help of upper limbs. The three methods were used simultaneously to quantify the jump height. The lowest correlation (r = 0.77; p &lt; 0.01) was found between VG and AB, while the strongest correlation (r = 0.92; p &lt; 0.01) was found between VG and TC methods. In addition, Bland and Altman plots revealed no satisfactory agreement between the methods. These findings suggest precaution to compare the results of vertical jump height from different methods.

title: Attitudes towards physical exercise and body image dissatisfaction of individuals who frequently go to gyms

description: AbstractThe aim of this study is to evaluate the body image dissatisfaction, and negative attitudes towards physical exercise, and the correlation among these two factors in individuals who frequently go to gyms. A sample of 100 sportspeople (67 women and 33 men) has answered electronically the Body Shape Questionnaire (BSQ) and Commitment Exercise Scale (CES). Participants also informed weight, height, time spent at the gym and their objectives in exercising. Pearson´s correlation analysis between BSQ and CES were evaluated, and CES scores were compared to BSQ classifications using Student's t-test. Differences between genders were evaluated using generalized linear model. Linear regression model tested predictors for body satisfaction and attitudes towards exercise. It was found that women have a higher level of body image dissatisfaction (p &lt; 0,001). Moreover, there was not any difference between sex in relation to physical exercises. There was not found any correlation between body image dissatisfaction and the attitudes towards physical exercises, however, there was a positive correlation between Body Mass Index (BMI) and body image dissatisfaction (p = 0,001 to men; p = 0,002 to women). The time spent at the gym was predictor to negative attitudes towards physical exercises (R2 = 0,580), and the BMI and a smaller importance of leisure in the practice of physical exercise were predictors of body insatisfaction (R2 = 0,368). Similar studies evaluating other body image aspects, such as drive for muscularity are needed.

title: Ball velocity on the kick in futsal: comparison between youth with different performance levels and correlation of the predictive variables of performance

description: AbstractThe aim of this study was to compare and verify the possible correlations between ball velocity with foot velocity, knee angle and length of last stride between practitioners and non-practitioners of futsal game. Fourteen young males with aged between 13 and 15 years old divided into two groups: practitioners (G1) and non-practitioners (G2), according with the time of futsal structured practice. For the kinematic analysis we had used two cameras at a sampling frequency of 120 Hz, fixed laterally to the movement performed in order to focus the markers in the limb of kick. Each participant has performed ten kicks simulating a kick of ten meters in futsal. Three-dimensional data of the lower limb of kick were obtained in DVIDEOW software and treated in Matlab environment in order to obtain the variables of interest: ball velocity (VELBALL), foot velocity (VELFOOT), knee angle (ANGKNEE) and length of last stride (LLS). Statistically all data displayed higher levels in G1 compared to G2. In addition, no significant differences were found between trials in each group (p &lt; 0.05). In G1 a multiple regression analysis revealed only influence on VELBALL 17% caused by LLS. Moreover, in G2 any variable have influenced VELBALL. However, we conclude that the variables are different between practitioners and non-practitioners of futsal game with aged between 13 and 15 years old, and the variable VELBALL could be little influenced by the LLS in this age band. Thus, we suggested that coaches maintain focus on development and monitoring this characteristic of movement, especially in novices, in order to identify players with different levels of performance of kicking in a futsal context.

title: Network design of a social sports project: actors, representations and meanings

description: This study is offered with the aim of exploring the meanings assigned by a network of actors who develops a social sports project. The Boxing Project Vidigal (PBV) has its activities in the Vidigal slum, located in the south of the city of Rio de Janeiro, next to the neighborhood of Leblon. The methodology used in this study was based on the procedures of network analysis and also the construction of categories, based on the definition of the core and the periphery of representations. We conclude that there is great centralization of the person who conceived the project, for this reason there is low density and high centrality in the network. The perceptions of the actors roam the ideas that the project "changes people's lives," that young people "become less aggressive," that there are "social contribution in the formation of children, youth and families" and promotes "social inclusion of people living in poor.

title: Analysis of the offensive patterns of the Spanish National Soccer Team in the 2010 FIFA® World Cup, in relation to match status

description: This paper aimed to analyze the tactical behavior of Spain National Football Team during the FIFA(r) World Cup, in four different match statuses: Draw, Win+1, Win+2, and Loss-1. The sample comprised 894 offensive sequences performed over Spain's seven matches during the tournament. Data analysis was performed through observations of video footage recorded from a TV station. Following variables were analyzed of play: Achievement time of the attack, Number of contacts with the ball, Number of balls received/Number of passes, Ball transmission speed, Location of acquisition and recovery of ball possession and Form of acquisition and recovery of ball possession. Descriptive statistics were conducted, and so were Chi-Square and Kruskal-Wallis tests. The significance level was set to p &lt; 0.05. Significant differences were found for the following variables: "ball transmission speed", "location and form of acquisition and recovery of ball possession". In conclusion, it was possible to infer that the tactical behavior of the Spanish team underwent few modifications during the tournament regarding match status.

title: Effect of β-alanine supplementation on 20 km cycling time trial performance

description: The effects of β-alanine supplementation on high-intensity cycling performance and capacity have been evaluated, although the effects on longer duration cycling performance are unclear. Nineteen UK category 1 male cyclists completed four 20 km cycling time trials, two before and two after supplementation with either 6.4 g•d-1 β-alanine (n = 10; BA) or a matched placebo (n = 9; P). Performance time for the 20 km time trial and 1 km split times were recorded. There was no significant effect of β-alanine supplementation on 20 km time trial performance (BA-pre 1943 ± 129 s; BA-post 1950 ± 147 s; P-pre 1989 ± 106 s; P-post 1986 ± 115 s) or on the performance of each 1 km split. The effect of β-alanine on 20 km time trial performance was deemed unclear as determined by magnitude based inferences. Supplementation with 6.4 g•d-1 of β-alanine for 4 weeks did not affect 20 km cycling time trial performance in well trained male cyclists.
