"I support you in everything": a qualitative study on maternal perception about their skating daughters

Abstract Aim: The study aimed to understand the perceptions of mothers about the practice of figure skating by their daughters aged between 8 and 13 years old. Methods: Eight mothers of skaters belonging to a youth competition team were interviewed in a qualitative study, which used narratives as the methodological approach. The interview was structured with open-ended questions and the full transcriptions were analyzed through content analysis. Results: The results of the three categories of analysis - "Skating and competing: the first influences"; "Family models and maternal participation"; and "Behavior of parents in sporting events" - showed that mothers perceived they provide emotional and motivational support during their daughters' sports practice and that they do not exert pressure for results. To not recognize negative behaviors could be negative to the skaters and may be the result of an inconscient mechanism or the need of mothers to have socially accepted behavior. They also stressed anxiety during competitions and reported strategies to cope with it. Thus, it is important to raise awareness of this situation so mothers can have more resources to manage this fragile balance. Conclusions: The way mothers participate in their children's sports life and express their support influences their sports practice; therefore, to understand how mothers perceive their involvement in their daughters' sportive practice is important to develop best practices to guarantee the quality of the interaction between mothers-children and healthy psychological development.

Effects of linear and undulating periodization of strength training in the acceleration of skater children

Aim: This study aimed to compare the effects of linear periodization (LP) and undulating periodization (UP) of strength training on acceleration in skater children. Methods: Twenty-nine girls (9.67±1.29 years-old, 34.47±8.06kg, 1.39±0.13m) were distributed into two groups: linear periodization group (LPG, n=14) and undulating periodization group (UPG, n=15). Six levels of progressive training were designed based on activities such as multi-jumps, plyometrics, sled towing, and facilitated exercises. The training lasted 16 weeks, with a 1-h session on three non-consecutive days per week. The acceleration was recorded by digital videography following the major trochanter of the femur, at four moments and under two conditions: static (SS) and dynamic start (DS) in a rectilinear path. Statistical significance was set at 5%. Results: ANOVA indicated group*moment interaction in SS and DS for velocity (F3,81=7.883; p<0.001; pη2=0.226; F3,81=2.36; p=0.078; pη2=0.08-trend, respectively) and acceleration (F3,81=3.96; p=0.011; pη2=0.128; F3,81=2.92; p=0.039; pη2=0.098, respectively). Both groups increased velocity in SS and DS (UPG/SS: 1st=4.07, 2nd=9.75, 3rd=8.91, 4th=9.25m/s; LPG/SS: 1st=4.27, 2nd=7.13, 3rd=7.61, 4th=7.99m/s; UPG/DS: 1st=8.30, 2nd=8.73, 3rd=8.12, 4th=9.27m/s; LPG/DS: 1st=8.20, 2nd=8.31, 3rd=7.90, 4th=8.96m/s) and acceleration (UPG/SS: 1st=2.00, 2nd=8.69, 3rd=4.71, 4th=5.02m/s2; LPG/SS: 1st=2.37, 2nd=3.39, 3rd=3.68, 4th=4.12m/s2; UPG/DS: 1st=1.78, 2nd=1.97, 3rd=1.65, 4th=2.46m/s2; LPG/DS: 1st=1.67, 2nd=1.70, 3rd=1.48, 4th=1.93m/s2). Conclusion: Both strength training periodization protocols were effective in developing acceleration and velocity in girl skaters over 16 weeks; however, UP was more efficient than LP for improving acceleration.(AU)

Skatistas "correndo pelo certo": normalização e produção de subjetividades na contemporaneidade / Skateboarders "going for the right": normalization and subjectivity production in contemporaneity / Skaters "corriendo por lo bueno": normalización y producción de subjetividades en la contemporaneidad

Este estudo visou analisar parte dos processos de produção das subjetividades skatistas nas suas relações com determinadas normas sociais em jogo na contemporaneidade, especificamente, através de uma vontade de inclusão de indivíduos e grupos sociais posicionados como anormais. A cartografia social foi usada como referencial teórico-metodológico e o material empírico baseou-se em falas de entrevistas ao rádio e à TV, conversas informais, cartazes de eventos, fotos retiradas de redes sociais no modo público e registros de Diário de Rua. Analisamos vetores de normalização sobre os skatistas articulados a determinadas normas sociais, através de ações e falas moralmente reconhecidas como "do bem", com vistas a atribuir traços de legitimidade e normalidade estratégicos no jogo incessante das relações de poder e da condução de si mesmos(AU)

This study aimed to analyze part of the processes of production of skateboarder's subjectivities in their relations with certain social rules that are in place in contemporaneity, specifically through a wish for inclusion by individuals and social groups positioned as abnormal. Social cartography was used as a theoretical-methodological framework and the empirical material included radio and TV interviews, informal conversations, posters of events, pictures taken from social media sites open to the public and street diary notes. We analyzed vectors of normalization related to skateboarders by connecting them with certain social norms through actions and speeches morally recognized as being "for the good", in order to ascribe traits of legitimacy and normalcy that are strategic to the permanent game of power relations and conduction of oneself(AU)

Jovens praticantes de skate e seu cotidiano / Young skateboarders their everyday / Jóvenes praticantes del skate y su vida cotidiana

Nessa pesquisa, focamos os jovens e seu cotidiano, trazendo elementos que discutem o lazer, família, educação e trabalho. Pesquisa realizada com um grupo de jovens skatistas, numa pista pública de skate na cidade de Porto Alegre - RS. Foram ao todo nove meses de observação direta, cada qual relatada em Diários de Campo. Procuramos compreender como o lazer dos jovens que se dava pela prática do skate, se relacionava como outros aspectos de seu cotidiano. Após concluir o trabalho, consideramos que - para se manter na prática do skate - os jovens necessitam conciliar as cobranças de suas famílias, além das rotulações e estereótipos impostas de fora do universo de praticantes desse esporte. Percebemos, ainda, que os jovens passam por tudo isso com o propósito de manter seus "projetos" no skate.

In this research, we focus on young people and their daily lives, bringing elements discussing leisure, family, education and work. Research conducted with a group of young skaters in a public track skating in the city of Porto Alegre - RS. In a total nine months of direct observation, each reported in Field Diaries. We seek to understand how the leisure of young people who gave the practice of skateboarding, was related to other aspects of their daily lives. After completing the work, we consider that - to remain in practice the skateboard - young people needed to reconcile the charges of their families, in addition to labels and stereotypes imposed from "outside" the universe of practitioners of this sport. We noticed also that young people go through all this in order to keep their "projects" on the skateboard.

En esta investigación, nos centramos en los jóvenes y su vida diaria, con lo que los elementos en discusiones sobre ocio, la familia, la educación y el trabajo. Investigaciones llevadas a cabo con un grupo de jóvenes praticantes del skate en una pista de patinaje pública en la ciudad de Porto Alegre - RS. En un total de nueve meses de la observación directa, cada informó en Diarios de Campo. Buscamos entender cómo el ocio de los jóvenes que dieron a la práctica de skate, estaba relacionada con otros aspectos de su vida cotidiana. Después de completar el trabajo, consideramos que - permanezca en la práctica el consejo - los jóvenes necesitan para conciliar los cargos de sus familias, además de etiquetas y estereotipos impuestos desde "fuera" del universo de los practicantes de este deporte. Notamos también que los jóvenes pasar por todo esto con el fin de mantener sus "proyectos" en el skate.

Antropometría, composición corporal y somatotipo de las patinadoras de elite en patinaje artístico sobre ruedas: análisis por disciplinas / Anthropometry, body composition and somatotype characteristics of world class female roller skaters by discipline

El objetivo de este estudio fue describir y comparar las características antropométricas, composición corporal y somatotipo de patinadoras de patinaje artístico sobre ruedas por categorías (junior y senior) y por disciplinas (individual, parejas y danza). Fueron evaluadas 62 patinadoras profesionales (36 en la disciplina de libre, 13 en danza y 13 en parejas). El análisis estadístico utilizado fue una ANOVA para muestras independientes entre disciplinas, y una T de Student para las categorías (junior y senior). Entre la categoría junior y senior no se han encontrado diferencias estadísticas significativas. Las patinadoras junior presentaron un somatotipo endo-mesomorfo, y las patinadoras senior presentaron un somatotipo mesomorfo balanceado. El somatotipo de las patinadoras de parejas y danza fue el mesomórfico balanceado, y el de las patinadoras de libre fue endo-mesomórfico. Este estudio aporta datos biotipológicos de referencia para la población de elite de patinadoras sobre ruedas.

The aim of the study was to describe and compare anthropometric characteristics, body composition and somatotype of female roller skaters by levels (Junior and Senior) and by disciplines (freestyle, pairs and dance). Sixty-two world class female roller skaters were assessed (36 freestyle roller skaters, 13 dance roller skaters and 13 pair roller skaters). A one-way analysis of variance (ANOVA) was used to determine if significant differences existed in the anthropometric profile among skating discipline and a student t test in order to assess differences between junior and senior levels. There are no significant differences between junior and senior roller skaters. Junior female roller skaters show an endo-mesomorphic somatotype and senior female roller skaters show a balanced mesomorphic somatotype. Roller dance skaters and roller pair skaters show a balanced mesomorphic somatotype and roller freestyle skaters show an endo-mesomorphic somatotype. This paper, reports specific reference data for world class female roller skaters.

Voga esportiva e artimanhas do corpo / Sportive vogue and body's tricks

Ao longo da história, inumeráveis formas de intervenção sobre os corpos foram sendo colocadas em prática em diferentes dimensões da vida. Elas expressam maneiras de educar os corpos que se constituíram em processos de inclusão ou exclusão de indivíduos e grupos. Dentre essas dimensões, certamente o esporte possui grande relevância. Assim, neste artigo, temos como objetivo analisá-lo como modelo universal de organização das práticas corporais contemporâneas e forma especifica de educação do corpo. Para tanto, tomaremos como eixo de nossa discussão uma das práticas contemporâneas de maior visibilidade entre os jovens brasileiros: o skate, ou, como preferem alguns, o skatismo.

Throughout history, countless forms of intervention on the bodies were put into practice in different aspects of life. They express ways of educating the bodies that formed in processes of inclusion or exclusion of individuals and groups. Among these dimensions, the sport certainly has great relevance. So in this article, we aim to analyze it as a universal model of organization of the contemporary body practices and specific forms of education of the body. For this, we will take as a point of our discussion of the contemporary practices of visibility among young brazilians: skateboarding, or, as some prefer, the skatismo.

A lo largo de la historia, innumerables formas de intervención sobre los cuerpos se pusieron en práctica en diferentes aspectos de la vida. Ellas expresan maneras de educar a los cuerpos que se formaron en los procesos de inclusión o exclusión de individuos y grupos. Entre estas dimensiones, sin duda el deporte tiene una gran relevancia. Es por ello que en este artículo, nuestro objetivo es analizarlo como un modelo universal de organización de las prácticas corporales contemporáneas y formas específicas de la educación del cuerpo. Para ello, tomaremos como punto de nuestra discusión una de las prácticas contemporáneas de más visibilidad entre los jóvenes brasileños: el skate, o, como prefieren algunos, ló skatismo.

Lazer e cidade: em foco a praça do gaúcho em Curitiba / Leisure and city: a focus on the square gaúcho in Curitiba

Esta pesquisa buscou analisar, na perspectiva dos frequentadores, o perfil dos usuários, as formas de usos e a ação das políticas públicas na Praça do Gaúcho localizada na cidade de Curitiba-PR. A análise foi feita com base em questionários respondidos por 53 frequentadores da Praça, aplicação de protocolos de investigação sobre a infraestrutura do espaço e equipamentos, e, por fim, observações. Percebeu-se que a Praça apresenta diferentes formas de uso. A principal é a prática do skate, combinada com outras experiências no âmbito do lazer. Além disso, a falta de policiamento, a iluminação deficitária e o sentimento de insegurança são fatores interrelacionados e, segundo os usuários questionados, estão vinculados à falta de políticas públicas mais atuantes. Conclui-se também que por meio dos usos combinados a Praça do Gaúcho apresenta-se como um espaço público que se transforma em um lugar dotado de significado, fortalecendo os laços sociais.

This research sought to examine the perspective of the regulars, the profile of users, forms of action and uses of public policy in "Gaúcho" Square in the city of Curitiba-PR. The analysis was based on questionnaires answered by 53 patrons of the Plaza, implementation of research protocols on the infrastructure space and equipment, and finally observations. It was felt that the square has different ways of use. The key is the practice of skateboarding, combined with other experiences within the leisure. Moreover, the lack of policing, lighting and deficient sense of insecurity factors are interrelated and, according to users questioned, are linked to lack of public policies more active. We also conclude that through the combined use of Gaucho Square presents itself as a public space that becomes a place endowed with meaning, strengthening social ties.

Exploración ecográfica al pie de patinadores / Echographic screening in the skater's foot

INTRODUCCIËN: La confluencia de factores que provocan la fricción del patín sobre ciertas áreas de los pies de patinadores durante sus entrenamientos ocasiona lesiones nodulares. OBJETIVO: Explorar y describir características imagenológicas de estas excrecencias circunscritas que se presentan en los pies de patinadores como consecuencia del sobreuso deportivo. MÉTODOS: Se realizó estudio transversal y descriptivo en 100 jóvenes masculinos no deportistas (controles) y en los 15 integrantes de la Preselección Cubana de Patinaje de carrera en abril de 2009 (10 varones y 5 hembras), todos con más de diez años de práctica deportiva sistemática. Se les realizó examen ecográfico diagnóstico en el Instituto de Medicina Deportiva para evaluar el estado de las estructuras articulares y periarticulares de esta región y los datos se procesaron mediante estadística descriptiva. RESULTADOS: Se verificaron distorsiones ecográficas en el 100 por ciento de los deportistas evaluados caracterizadas fundamentalmente por: engrosamiento dérmico circunscrito (100 por ciento), tendinitis (33,3 por ciento) y exostosis bursata (20 por ciento); manifestaciones todas incluidas en una afección que los autores identificaron como el pie del patinador cuya expresión clínica externa lo constituye la presencia de nódulos de localización retrocalcánea, región dorsal y/o medial del pie. CONCLUSIONES: El pie del patinador puede constituir una entidad nosológica que tiene sustento imagenológico y que se relaciona con la fricción directa y sistemática del patín, propia de este deporte y que no solo afecta la piel de los pies de los patinadores sino que puede interferir con el entrenamiento o competencia por la asociación con otras lesiones

INTRODUCTION: The convergence of factors leading to skate friction on some areas of skater's feet during trainings provoke nodular injuries. OBJECTIVES: To explore and to describe the imaging features of these circumscribed excrecences present in the skater's feet as consequence of sports overuse. METHODS: A cross-sectional and descriptive study was conducted in 100 young no-sportsmen (controls) and in the 15 members of the Cuban Pre-Selection of speed Skating in April, 2009 (10 boys and 5 girls), all of them with more than 10 years of systematic sports practice. Then underwent a diagnostic echographic examination in the Institute of Sports Medicine to assess the condition of articular and periarticular structures of this area and data were processed by descriptive statistics. RESULTS: There were demonstrated echographic distortions in 100 percent of assessed sportsmen, mainly due to: circumscribed dermic thickening (100 percent), tendonitis (33,3 percent) and exostosis bursata (20 percent), manifestations included in an affection identified by authors as skater foot whose external clinical expression is the presence of retrocalcaneal nodules, dorsal and/or foot medial region. CONCLUSIONS: The skater's foot may be a disease entity with an imaging support and is related to direct and systematic friction of skate, characteristic of this sport and that not only involve the teeth's skin but it may to interfere with treatment or competence due to its association with other injuries

O segredo do sucesso: apontamentos sobre a trajetória social de skatistas profissionais / El secreto del succeso: apuntes sobre la trayectoria social de skatistas profesionales / The secret of success: notes on the social trajectory of professional skaterboarders

Este artigo aponta, a partir de casos concretos, para elementos acerca da trajetória social de skatistas que lograram estar no subuniverso dos patrocínios. Em se tratando de skate, isso significa praticamente a única possibilidade de profissionalização. São considerados detalhes da constituição e do funcionamento do campo do skate em sua totalidade e da vida dos informantes, de seu caminho para incorporar disposições e capitais válidos no contexto do skate. Os dados utilizados são provenientes de técnicas de pesquisa como a entrevista semiestruturada, a observação participante e a coleta de documentos.

The aim of this article is to look at specific real life cases of the social trajectory of skateboarders, who managed their skateboarding career whilst not being in the mainstream of sponsorship. In skateboarding sponsorship is almost the only viable means to be professionally and thus financially stable.

Intertrochanteric Fractures from In-line Skating

Although the risk of incurring factures of the upper extremity that are associated with in-line skating is well known, the incidence of low extremity injuries was reported to be low and so this has not yet been highlighted so far. We have experienced two cases of intertrochanteric fractures that occurred to active, middle-aged adults during in-line skating and we report on these cases along with a review of the relevant literatures.

Pattern of In-line Skate Injury and The Effect of Protective Gear in School Children / 대한정형외과학회잡지

PURPOSE: Despite the rapid increase in the number of in-line skaters, there are few epidemiological studies reported on in-line skate injuries in Korea. This study investigated the pattern of in-line skate injuries in a population of school children, with a particular attention being paid to the effect of protective gear in its prevention. MATERIALS AND METHODS: A questionnaire was given to all school children from 8 elementary schools in an urban area. A total of 13, 482 children and/or their parents were enrolled in this study. The number of in-line skaters, the habit of wearing protective gear, the history of any injury including fractures, and the pattern and etiology of fractures in these children were examined during 2003. RESULTS: Of the responders, 84.6% enjoyed in-line skating. The yearly incidence of in-line skate injuries in 2003 was 39.0% with 1.3% involving fracture.Only 17.0% of in-line skaters wore protective gear, which decreased the incidence of fracture by 72.7%. As they grow older, fewer children were wearing protective gears with a corresponding increase in the incidence of fractures. CONCLUSION: In-line skate injuries are a significant health problem in school children. The use of the protective gear should be encouraged, particularly in older age group.

In-line Skating Injuries and Rehabilitation

In-line skating is one of the fastest growing recreational sport activities all over the world, particularly in Korea. Fractures, dislocations, sprains and avulsions account for 60~70% of all acute injuries from in-line skating. The wrist area, including the wrist and the lower arm, is the most commonly injured site. To decrease the incidence and severity of acute injuries, the use of safety gears is critical. Also, overuse injuries can occur in the shoulder area, low back, knee, foot and ankle. Avoidance of overwork, rest, stretching and strengthening exercise, well-fit boots, and the proper skating posture can prevent or minimize the overuse injuries.

Most common injuries associated to scooters seen in the emergency department

The foot propelled scooter is a popular toy preferred by girls and boys, but at the same time, these put the children at risk of some kind of injury. The literature had reported that the fractures at the upper extremities are the most frequent injury observed related to the use of a scooter. The purpose of our study was to describe the injuries related to the scooters use in a sample of injuries handled at the UPR Hospital at Carolina, Puerto Rico. A total of 62 patients who arrived to the ED and were evaluated for some kind of injury related to the use of scooters were included in our study. Fractures (32.3) constituted the most frequent injury observed in the sample, followed by the lacerations (29.0), and the abrasions (11.3). The parents, doctors and the healthcare workers should be made aware of the causes and prevention of injuries caused by the foot propelled scooters, because this situation is potentially preventable
