A disciplina psicologia do esporte nos cursos de psicologia e educação física / Sports psychology in psychology and physical education courses / La materia psicología del deporte en los cursos de psicología y educación física

Este discute a representatividade da disciplina Psicologia do Esporte nos cursos de Psicologia e Educação Física em instituições de ensino superior reconhecidas pelo MEC e situadas na região Sul do país. Foi realizado um estudo documental, com base nos currículos das Instituições. Os resultados revelaram que no Sul do Brasil 21,02% dos cursos de Psicologia, 41,96% dos cursos de bacharelado em Educação Física e apenas 14,83% dos cursos de licenciatura em Educação Física apresentam a disciplina Psicologia do Esporte em sua grade curricular. Observou-se que a disciplina é ofertada mais frequentemente em regime obrigatório nos cursos de bacharelado em Educação Física. Nos cursos de Psicologia, quando ofertada, costuma ser optativa. Os resultados evidenciam uma maior oferta da disciplina para os estudantes de Educação Física, em relação aos de Psicologia, o que pode estar relacionado ao próprio contexto de surgimento da disciplina e sua popularização no meio acadêmico. Para que esse panorama possa mudar e se possa oferecer uma formação adequada no curso de Psicologia para fomentar essa opção de carreira, há necessidade de se repensar o currículo e o próprio perfil do egresso, de forma a dar mais oportunidade aos estudantes para que conheçam as bases teóricas e os campos de aplicação da Psicologia do Esporte. Tal lacuna pode acarretar a fragilização da disseminação desse conhecimento aos estudantes de graduação e a consequente ocupação do mercado de trabalho.(AU)

This study discusses the representativeness of Sports Psychology in Psychology and Physical Education courses at higher education institutions from Southern Brazil. A documentary study was conducted based on the institutions' curricula. Results show that 21.02% of the Psychology major, 41.96% of the bachelor's in Physical Education, and only 14.83% of the license in Physical Education offer Sports Psychology in their curricula. Sports Psychology is most often offered as a compulsory subject in the bachelor's program in Physical Education, whereas Psychology courses offer it mainly as an elective. Physical Education students have greater contact with the discipline when compared with Psychology students, which may be explained by its context of development and popularization in the academic environment. To change this scenario and offer adequate education in the Psychology programs to foster this career option, institutions must rethink their curriculum and the graduate profile itself. This would give students better opportunity to get to know its theoretical bases and fields of application. Such a gap can hinder the dissemination of this knowledge to undergraduate students and the consequent labor market occupation.(AU)

El objetivo de este estudio es discutir la representatividad de la materia Psicología del Deporte en los cursos de Psicología y Educación Física en instituciones de educación superior de la región Sur de Brasil, reconocidas por el Ministerio de Educación (MEC). Se realizó un estudio documental, basado en los planes de estudio de las instituciones. Los resultados revelaron que, en el Sur de Brasil, el 21,02% de los cursos de Psicología, el 41,96% de los cursos de licenciatura en Educación Física y sólo el 14,83% de los cursos de profesorado en Educación tienen la materia Psicología del Deporte en sus planes de estudio. Se observó que la materia Psicología del Deporte se ofrece con mayor frecuencia como asignatura obligatoria en los cursos de licenciatura en Educación Física. Cuando se ofrece en los cursos de Psicología, es una materia optativa. Los resultados muestran una mayor oferta para los estudiantes de Educación Física en comparación con Psicología, lo que puede estar relacionado con el contexto del surgimiento de la Psicología del Deporte como materia y su popularización en el ámbito académico. Para que este escenario cambie y sea posible ofrecer una formación adecuada en el curso de Psicología con el fin de fomentar esta opción de carrera, es necesario repensar el plan de estudios y el perfil del egresado, así los estudiantes tendrán más oportunidades de conocer sus bases teóricas y sus campos de actuación. Tal brecha puede debilitar la difusión de este conocimiento a los estudiantes de grado y la consecuente ocupación en el mercado laboral.(AU)

Processos de reflexividade dos psicólogos do esporte e coaches: um estudo fenomenológico / Reflexivity processes of sport psychologists and coaches: a phenomenological study / Procesos de reflexividad de psicólogos del deporte y coaches: un estudio fenomenológico

O objetivo desta pesquisa é identificar e compreender fenomenologicamente, por meio de relato de Psicólogos de Esporte (PE) e de Coaches, em sua vivência prática, como ocorrem os processos reflexivos em sua atuação, conforme apreendidos a partir de relatos de experiências. O método de investigação escolhido foi a fenomenologia, pois oferece os recursos necessários para tal mergulho junto à experiência reflexiva. A amostra intencional foi delineada por PE e Coaches (profissionais de Educação Física que recorrem ao Coaching) em atividade em esportes de alto rendimento, que tenham atuado ou estejam atuando em modalidades esportivas coletivas e/ou individuais. Realizaram-se nove entrevistas (cinco com PE, quatro com Coaches). O acesso ao objeto desse estudo se deu por meio de entrevistas em profundidade e semiestruturadas, orientadas pela escuta suspensiva. As questões disparadoras foram formuladas com base no Procedimento Estruturado de Reflexão adaptado. Para análise das entrevistas, realizou-se uma síntese de cada relato, seguindo-se de cruzamento intencional. Como resultados, percebeu-se que PE e Coaches trazem algumas similaridades no que se refere aos modos de refletir sobre sua prática. No entanto, as experiências que eles fazem desses processos reflexivos é que podem tomar rumos distintos. Os(as) PE amparam-se na regulamentação da profissão e resguardam-se em seus apontamentos, trazendo suas experiências e reflexões sobre os processos vividos. Os(as) Coaches trazem em suas explanações um trabalho coerente, organizado e compatível com o método do Coaching. Problematizar os processos reflexivos desses profissionais permite diferenciar qualitativa e eticamente suas atuações, possibilitando o fomento multiprofissional no esporte.(AU)

The aim of this study consists in phenomenologically identifying and understanding, by the report of Sport Psychologists (SP) and coaches, in their practical experience, how would be the reflexive processes that take place in their performance, as learned from reports of their experiences. The research method chosen was phenomenology, since it offers the necessary resources for such a dive along with the reflective experience. The intentional sample was outlined by SP and coaches (Physical Education professionals who use coaching) active in high performance sports, who have or are working in collective and/or individual sports. Nine interviews were conducted (five with SP, four with coaches). Access to the object of this study took place by in-depth and semi-structured interviews, guided by suspensive listening. The triggering questions were formulated based on the adapted Structured Reflection Procedure. For the analysis of the interviews, a synthesis of each report was carried out, followed by the intentional crossing. As results, it was noticed that SP and coaches bring some similarities regarding the ways of reflecting on their practice. However, their experiences of these reflective processes are that they can take different directions. The SP are based on the regulation of the profession and guard themselves in their notes, bringing their experiences and reflections on the processes experienced. Coaches bring in their explanations a coherent, organized, and compatible work with the coaching method. Problematizing the reflective processes of these professionals allows to differentiate their actuation qualitatively and ethically, making the multiprofessional phenomenon in sport possible.(AU)

El objetivo de este estudio consiste en identificar y comprender fenomenológicamente, a partir de la experiencia práctica de psicólogos del deporte (PD) y coaches, cómo serían los procesos reflexivos que se llevan a cabo en su rendimiento, tal y como se desprende de los informes de experiencias. El método de investigación elegido fue la fenomenología, ya que ofrece los recursos necesarios junto con la experiencia. La muestra intencional fue delineada por PD y coaches (profesionales de la educación física que utilizan el coaching) activos en deportes de alto rendimiento, que tienen o están trabajando en deportes colectivos e/o individuales. Se realizaron nueve entrevistas (cinco con PD, cuatro con coaches). El acceso al objeto de este estudio fue entrevistas en profundidad y semiestructuradas, guiadas por escuchas suspensivas. Las preguntas se formularon desde el procedimiento de reflexión estructurado adaptado. Para el análisis de las entrevistas, se hizo una síntesis de cada informe, seguida del cruce intencional. Como resultados, se notó que los PD y coaches tienen algunas similitudes con respecto a las formas de reflexionar sobre su práctica. Sin embargo, las experiencias que hacen de estos procesos pueden tomar diferentes direcciones. Los(las) PD se basan en la regulación de la profesión y se protegen en sus notas, aportando sus experiencias y reflexiones sobre los procesos vividos. Los(las) coaches plantean en sus explicaciones un trabajo coherente, organizado y compatible con el método de Coaching. Problematizar los procesos reflexivos de estos profesionales permite diferenciar sus acciones de manera cualitativa y ética, además de posibilitar la promoción multiprofesional en el deporte.(AU)

Are there lane advantages in track and field?

Shorter distance events in track and field are replete with folk tales about which lane assignments on the track are advantageous. Estimating the causal effect of lane assignments on race times is a difficult task as lane assignments are typically non-random. To estimate these effects I exploit a random assignment rule for the first round of races in short distance events. Using twenty years of data from the IAAF world athletic championships and U20 world championships, there is no evidence of lane advantages in the 100m. Contrary to popular belief, the data suggest that outside lanes in the 200m and 400m produce faster race times. In the 800m, which is unique in having a lane break, there is some weak evidence that outside lanes producer slower race times, possibly reflecting the advantage of inside lanes having an established position on the track at the lane break. Given that these results do not support common convictions on lane advantages, they also serve as an interesting case study on false beliefs.

Improved Physiological Markers of Omega-3 Status and Compliance With Omega-3 Supplementation in Division I Track and Field and Cross-Country Athletes: A Randomized Controlled Crossover Trial.

A sufficient omega-3 index may enhance cardiovascular function, enhance performance, and decrease inflammation. However, most collegiate athletes are deficient in omega-3s, requiring supplementation. A new type of omega-3 (N3) supplement, Enhanced Recovery™ (ER), claims to improve N3 index while addressing the current issues with traditional supplementation. The purpose of this study was to determine if ER improves N3 status and enhances compliance compared with the current standard in collegiate Division I Track and Field and cross-country athletes during a competitive season. Twenty-five (male = 15 and female = 10) athletes completed this longitudinal, randomized controlled crossover trial. Measurements of N3 status were collected at baseline prior to supplementation, and every 2 weeks for 6 weeks with a 33- to 36-day washout period before crossing over. Supplement compliance and dietary intake of N3 rich foods were collected throughout. Visual analog scales and an exit survey asked questions regarding each treatment. Results showed that N3 index increases within 6 weeks (p < .001) for ER (+37.5%) and control (CON; +55.1%), with small differences between treatments at Weeks 4 (ER = 7.3 ± 1.0; CON = 7.7 ± 1.1; p = .043) and 6 (ER = 7.4 ± 1.2; CON = 7.9 ± 1.2; p = .043). Dietary intake of N3-rich foods and supplement compliance were significant drivers of improvements in N3 status (p < .050). Compliance was not different between treatments but was affected by sex (males = 90.0 ± 17.0% and females = 76.5 ± 21.0%; p = .040), likability (p = .001; r = .77, p < .001), ease (p = .023; r = .53, p = .006), and supplement preference (p = .004), which appeared to favor ER. We conclude that consumption of N3-rich foods and consistent supplementation should be implemented for improvements in N3 status in collegiate athletes, but taste tests/trial periods with ER or CON may help determine preference and improve compliance.

Effects of Co-Ingestion of ß-Hydroxy-ß-Methylbutyrate and L-Arginine α-Ketoglutarate on Jump Performance in Young Track and Field Athletes.

The aim of the study was to determine the effect of simultaneous supplementation of ß-hydroxy-ß-methylbutyrate and L-Arginine α-ketoglutarate on lower limb power and muscle damage in medium distance runners aged 15.3 (±0.9) years old. METHODS: The study group consisted of 40 volunteers aged 14-17 years practicing medium distance running for at least two years. The study lasted 12 days and followed a randomized, double-blind, placebo-controlled, parallel design. All subjects attended a familiarization session on day 0 before the test. The subjects were randomly divided into two groups: supplements and placebo group. The same training cycle protocol was used in both groups during the 12-day training period. Morning warm-up involved 10 min jogging at 60-75% of maximal heart rate and countermovement jump height measurement. Main training units were carried out for both groups with the same volume. Training load assessment (the daily session Rating of Perceived Exertion (s-RPE) method) method takes into consideration the intensity and the duration of the training session to calculate the "training load" (TL). RESULTS: At the end of the training cycle, a significant (p = 0.002) decrease in the countermovement jump (CMJ) height was found in the placebo group when compared to the baseline. In the supplement group, there was no decrease in the countermovement jump height. Creatine kinase and lactate dehydrogenase concentration increased during the training days similarly in both groups and decreased on rest days. There were no differences between groups in enzymes concentration. The research results indicate that the supplement combination used in the supplements group prevented a reduction in the CMJ values. In contrast to the supplements group, in the placebo group, the CMJ changes were statistically significant: a noticeable (p = 0.002) decrease in CMJ was noted between the baseline measurement and the 6th measurement. The well-being of the subjects from both groups changed significantly during the training period, and the intergroup differences in the mood level were similar and not statistically significant. CONCLUSIONS: The results of this study indicate that the daily co-supplementation with calcium salt of ß-hydroxy-ß-methylbutyrate (7.5 g) and L-Arginine α-ketoglutarate (10 g) during training might help to prevent decline in jump performance. No influence on muscle damage markers or mood was shown.

Elite athletes' experiences of musculoskeletal pain management using neuroanatomical dry needling: A qualitative study in Swedish track and field.

OBJECTIVES: To investigate how elite track and field athletes with a history of musculoskeletal pain (MSKP) describe their perceptions of clinical treatments based on dry needling guided by a neurological map (neuroanatomical dry needling (naDN)). DESIGN: Qualitative study. METHODS: In-depth interviews were conducted with eight elite Swedish track and field athletes (6 males, 2 females, median age 28.5) treated at a clinic specialised in MSKP management. All interviews were audio recorded and transcribed verbatim. The data were structured and analysed using a thematic method. RESULTS: The athletes approached clinical MSKP treatment from a performance-orientated perspective. They explained that they inevitably suffered MSKP episodes due to the intense physical demands of their sport. The use of naDN was considered an integral part of their sports practice and the study clinic's services were readily utilised when MSKP caused minor reductions in physical capacity. The athletes appreciated an unambiguous anatomical diagnosis, preferably supported by imaging scans, as this increased their confidence in clinical services. They valued the naDN treatment as it was perceived to provide fast-acting analgesia that enabled rapid return-to-play. These factors combined to reduce performance-related stress. CONCLUSIONS: Elite track and field athletes with a history of MSKP sought and appreciated clinical treatment with naDN largely because it provided fast-acting analgesia that enabled rapid return-to-play at a high-performance level. These athletes' expectations of MSKP diagnosis and management appear incongruent with current research indicating that MSKP sensitivity within the nervous system does not accurately reflect musculoskeletal tissue state or recovery following tissue damage.

Impact of the talent development environment on the wellbeing and burnout of Caribbean youth track and field athletes.

This study examined the perceived talent development environment (TDE) of youth track and field athletes within the Caribbean region and explores the relationship with their subjective wellbeing and burnout levels. A sample of 400 Caribbean youth track and field athletes (male = 198, and female = 202; age 13-20 years) participated in this cross-sectional study. Athletes responded to a survey which included the Talent Development Environment Questionnaire (TDEQ-5), the World Health Organization Wellbeing Index (WHO-5) and the Athlete Burnout Questionnaire (ABQ). Structural equation modelling showed that a positive and supportive TDE was associated with better athlete wellbeing and lower athlete burnout. Moreover, gender and hours of training moderated relationships of athletes' perceptions of their development environment with wellbeing and burnout levels respectively. Furthermore, there was a positive association between the support network and athlete wellbeing, while holistic quality preparation was negatively associated with athlete burnout. Development environments perceived as supportive and geared towards a holistic athlete-centred approach were associated with better athlete wellbeing and lower burnout.

Categorizing 10 Sports According to Bone and Soft Tissue Profiles in Adolescents.

PURPOSE: Considering the different loading and training characteristics of the sports practiced during growth, it is important to specify and categorize the bone and soft tissue adaptations in adolescent athletes. This study aimed to categorize 10 different loading sports and a nonsport group and identify the differences in bone density and soft tissues. METHODS: The sample included 625 adolescents (10 to 17 yr of age) of 10 sports (soccer, basketball, volleyball, track and field, judo, karate, kung fu, gymnastics, baseball, and swimming) and a nonsport group. Dual-energy x-ray absorptiometry assessed areal bone mineral density (aBMD), bone mineral apparent density (BMAD), and soft tissues (lean soft tissue and fat mass). The results were adjusted for sex, peak height velocity status, lean soft tissue, fat mass, and weekly training volume. RESULTS: The comparisons among groups showed that soccer had the highest whole-body aBMD (mean ± SEM: 1.082 ± 0.007 g·cm) and lower limb aBMD (1.302 ± 0.010 g·cm). Gymnastics presented the highest upper limb aBMD (0.868 ± 0.012 g·cm) and whole-body BMAD (0.094 ± 0.001 g·cm). Swimming presented the lowest aBMD values in all skeletal sites (except at the upper limbs) and whole-body BMAD. The soft tissue comparisons showed that soccer players had the highest lean soft tissue (43.8 ± 0.7 kg). The lowest fat mass was found in gymnasts (8.04 ± 1.0 kg). CONCLUSION: The present study investigated and categorized for the first time 10 different sports according to bone density and soft tissue profiles. Soccer and gymnastics sport groups were found to have the highest bone density in most body segments, and both sports were among the groups with the lowest fat mass.

Use of nutritional supplements by elite Japanese track and field athletes.

BACKGROUND: While scientific evidence supports the efficacy of only limited nutritional supplements (NS) on sports performance, the use of NS is widespread in athletes. Given the serious issues of health damage or unintended Anti-Doping Rule Violations due to ingestion of contaminated NS in sports, accurately understanding NS practices by athletes is crucial. This study therefore elucidated the use of NS by elite Japanese track and field (TF) athletes. METHODS: The subjects were 574 Japanese TF athletes, including 275 junior athletes (under 20 years) and 299 senior athletes, who participated in international competitions from 2013 to 2018. Data on NS use were collected through pre-participation medical forms obtained from all entrants before their participation in competitions. NS users were requested to report the product names and primary components of all NS they were taking. RESULTS: The overall prevalence of NS use was 63.9%. The mean number of NS products used per athlete was 1.4. The prevalence was significantly higher in women (69.2%) than in men (59.6%) (p = 0.018) and significantly higher in senior athletes (68.9%) than in junior athletes (58.9%) (p = 0.012). The prevalence of NS use was higher in long-distance runners (75.8%) and lower in jumpers (52.3%) and throwers (49.2%) than other disciplines (p < 0.001). The most prevalent components were amino acids (49.3%), followed by vitamins (48.3%), minerals (22.8%), and protein (17.8%). CONCLUSIONS: Approximately two-thirds of elite Japanese TF athletes reported the use of NS, and NS practices varied by gender, age, and discipline.

Vários métodos de aquecimento têm sido empregados no campo do treinamento esportivo . O foam rolling (FR) é uma das técnicas mais populares. No entanto, permanece o esclarecimento so bre o s períodos ótimos de FR para melhorar ou manter o desempenho. Portanto, o objetivo do presente estudo foi explorar o efeito agudo de diferentes períodos do FR no desempenho do salto vertical contramov iment o (SV). Doze indivíduos recreacionalmente ativos (23,92 ± 4,08 anos, 7 0 ± 1 2 k g, 1 71 ± 8 cm ) fo ram voluntários para o estudo. Todos os participantes completaram todos os protocolos ex perim en tais co m entrada randomizada. Os participantes realizaram seis visitas separadas por 48 horas. A primeira sessão incluiu a coleta de dados antropométricos, familiarização com o FR e a técnica do SV. Em seguida, cin co protocolos experimentais foram executados em ordem aleatória: Protocolo controle (PC) - salto v ertical sem FR; P30 ­ uma série de 30 segundos de FR antes do salto vertical; P60 - duas séries de 30 segun do s de FR; P90: três séries de 30 segundos de FR; P120 ­ quatro séries de 30 segundos de FR. O FR foi implementado para quadríceps, isquiotibiais, glúteo e gastrocnêmio. Diferenças significativas no desempenho do salto vertical (p <0,012) foram observadas no P30 (47,4 ± 11,7 cm), P60 (48,9 ± 11,9 cm), P90 (48,5 ± 12,1cm), P120 (48,6 ± 11,3 cm) em relação à PC (46,8 ± 11,3 cm). Além disso , P 60, P9 0, P120 apresentaram maior desempenho de salto vertical em relação ao p rotocolo P3 0. Po rtanto , o s praticantes e treinadores devem considerar a utilização de 60-120 segundos de FR durante o aquecimento, com o objetivo de melhorar o desempenho do SV...(AU)

Several warm-up methods have been employed in the field of athletic training. Th e foam rolling (FR) is one of the most popular techniques; however, there is still a lack o f ev idence abo ut t he optimal FR periods to enhance strength performance. Therefore, the purpose of the present study was t o explore the acute effect of different periods of the FR on vertical countermovement jump. Twelve recreationally active individuals (23.92 ± 4.08 years, 70 ± 12 kg, 171 ± 8cm) volunteered for t he st udy . Treatment conditions were participants using a random assignment. Participan ts p erform ed six v isit s separated by 48 hours. The first session included the collection of anthropometric data and familiarizatio n with a foam roller and the vertical countermovement jump technique. Then, five experimental p rotocols were employed in a randomized order: control protocol (CP) - the vertical countermovement without FR; P30 - one set of 30 seconds of FR before the vertical jump; P60 - two sets of 30 seconds of FR; P90: three sets of 30 seconds of FR; P120 - four sets of 30 seconds of FR. The FR was implemented for quadriceps, hamstrings, gluteus, and gastrocnemius. Significant differences in vertical countermovement jump performance (p < 0.012) were observed under the P30 (47.4 ± 11.7 cm), P60 (48.9 ± 11.9 cm), P90 (48.5 ± 12.1), P120 (48.6 ± 11.3 cm) compared to CP (46.8 ± 11.3 cm). In addit io n, P60 , P 90 , P 12 0 sh o wed greater vertical jump performance compared to the P30 protocol. Therefore, t he p ractition ers sh o uld consider utilizing 60-120 seconds of FR during the warm-up with the goal of acutely improving the vertical countermovement jump performance...(AU)

The Jumper's Knee - a New Look at Non-surgical Treatment. Pilot Study.

BACKGROUND: There are many opinions and views regarding the methods of treatment of patellar ligament enthesopathy. No gold standard of treatment exists. This paper presents our approach involving conservative treatment and an appropriate rehabilitation regime. Our aim was to assess the effectiveness of a combination of various conservative treatment techniques and the time needed to return to sport. MATERIAL AND METHODS: The study enrolled 14 patients treated in 2019 and 2020. Knee joint evaluation was based on clinical and radiological examination (sonography and MR). All patients were treated conservatively according to a specially prepared treatment protocol. Patients were evaluated at two-week intervals until the symptoms subsided completely. The KOOS, Kujala and SF36 questionnaires were used to evaluate the results. RESULTS: All of the patients returned to painless physical activity within 3-4 weeks from the start of treatment. In the group of professional athletes, 100% returned to sport. The return to sport took slightly longer for pa-tients with bilateral (5-6 weeks) in comparison to unilateral jumper's knee (3-4 weeks). The longest period of return to sport, in a patient who had severe pain at rest before starting treatment, was 7 weeks. Statistically significant improvement was noted in all of the questionnaires used and in all subdomains at 6 months after the beginning of the treatment. CONCLUSIONS: 1. The conservative approach proposed by us generated promising results in the treatment of the jumper's knee. 2. A 100% rate of return to sport was recorded among our patients.

Dupla carreira: dilemas entre esporte e escola / Dual career: dilemmas between sport and school

RESUMO Este artigo analisa os modelos de conciliação das rotinas na dupla carreira, esportiva e escolar, no Programa Bolsa Atleta do Governo Federal, com estudantes-atletas contemplados pelos resultados obtidos no ano de 2011. Caracteriza-se como uma pesquisa quantitativa realizada por meio de uma entrevista estruturada aplicada a 131 atletas das modalidades de atletismo, judô e natação, sendo 64 do sexo feminino e 67 do masculino. Os resultados evidenciam que: 1) as diferentes modalidades esportivas exigem dos seus atletas tempo e dedicação distintos; 2) processo de iniciação nas três modalidades exigem diferentes formas de investimentos; 3) menor escolaridade dos pais e atletas do atletismo, assim como, classe social mais baixa. Diante dos obstáculos da dupla carreira, atletas, clube, escola e famílias passam adotar táticas de conciliação e mesmo burla dos programas de suporte à formação esportiva.

Characterization as a quantitative research carried out by means of a structured interview invested in 131 athletes of the modalities of athletics, judo and swimming, being 64 female and 67 male. They show the following results: 1) as different sports modalities; 2) initiation process in the temporary variables of the forms of investment; 3) lower schooling of parents and athletes in athletics, as well as lower social class. In the face of the obstacles of the dual career, athletes, clubs, schools and families are adopting tactics of conciliation and even mockery of programs to support sports training.

Jogos escolares da rede pública do estado da bahia: análise das edições 2009 a 2017 / Bahia state public schools championship: analysis of editions from 2009 to 2017

RESUMO A partir da análise documental de 210 relatórios dos Jogos Escolares da Rede Pública da Bahia (JERP), este estudo teve por objetivo descrever a evolução histórica do JERP de 2009 a 2017, considerando as modalidades comuns e inovadoras ofertadas, número de escolares, número de escolas, número de professores e recursos financeiros descentralizados. Verificamos que as modalidades inovadoras foram numericamente superiores às modalidades comuns e apresentaram maior diversificação das práticas esportivas; o número de escolares, escolas e professores na primeira etapa dos jogos (dentro das escolas) foi superior a terceira etapa (regional), além de aumentar ao longo dos anos em ambas as etapas; e que o valor financeiro descentralizado tendeu a crescer no período histórico analisado. Concluímos que o JERP se apresenta como uma oportunidade dos alunos vivenciarem diferentes modalidades esportivas, entretanto esta oportunidade é ressaltada apenas na primeira etapa. Em relação aos recursos financeiros descentralizados para o JERP, parece não haver planejamento prévio com relação a proporção destes recursos e a proporção de escolares participantes deste programa. Sugerimos maior concentração de recursos em competições locais do que estaduais, uma vez que atendem mais crianças e jovens e favorecem a valorização da diversificação de modalidades e respeito à cultura esportiva local.

ABSTRACT Based on the documentary analysis of 210 reports of the Scholars Games of the Bahia State Public System (JERP), this study aimed to describe the historical evolution of the JERP from 2009 to 2017 considering the common and innovative modalities offered, number of school children, number of schools , number of teachers and decentralized financial resources. It was verified that the innovative modalities were numerically superior to the common modalities and presented a greater diversification of the sports practices; the number of students, schools, and teachers in the games' first stage (inside of the schools) was superior to the third stage (regional), besides increase over the years in both stages; and that the decentralized financial value tended to grow in the historical period analyzed. It is concluded that the JERP presents itself as an opportunity for students to experience different sports modalities, however this opportunity is highlighted only in the first stage. Regarding the decentralized financial resources for the JERP, there seems to be no prior planning regarding the proportion of these resources and the proportion of students participating in this program. We suggest a higher concentration of resources in local rather than state competitions, since the local competitions serve more children and young people and support the modalities diversification and respect to the local sports culture.

Nutrition for the Prevention and Treatment of Injuries in Track and Field Athletes.

Injuries are an inevitable consequence of athletic performance with most athletes sustaining one or more during their athletic careers. As many as one in 12 athletes incur an injury during international competitions, many of which result in time lost from training and competition. Injuries to skeletal muscle account for over 40% of all injuries, with the lower leg being the predominant site of injury. Other common injuries include fractures, especially stress fractures in athletes with low energy availability, and injuries to tendons and ligaments, especially those involved in high-impact sports, such as jumping. Given the high prevalence of injury, it is not surprising that there has been a great deal of interest in factors that may reduce the risk of injury, or decrease the recovery time if an injury should occur: One of the main variables explored is nutrition. This review investigates the evidence around various nutrition strategies, including macro- and micronutrients, as well as total energy intake, to reduce the risk of injury and improve recovery time, focusing upon injuries to skeletal muscle, bone, tendons, and ligaments.

Dietary Protein for Training Adaptation and Body Composition Manipulation in Track and Field Athletes.

Track and field athletes engage in vigorous training that places stress on physiological systems requiring nutritional support for optimal recovery. Of paramount importance when optimizing recovery nutrition are rehydration and refueling which are covered in other papers in this volume. Here, we highlight the benefits for dietary protein intake over and above requirements set out in various countries at ∼0.8-1.0 g·kg body mass (BM)-1·day-1 for training adaptation, manipulating body composition, and optimizing performance in track and field athletes. To facilitate the remodeling of protein-containing structures, which are turning over rapidly due to their training volumes, track and field athletes with the goal of weight maintenance or weight gain should aim for protein intakes of ∼1.6 g·kg BM-1·day-1. Protein intakes at this level would not necessarily require an overemphasis on protein-containing foods and, beyond convenience, does not suggest a need to use protein or amino acid-based supplements. This review also highlights that optimal protein intakes may exceed 1.6 g·kg BM-1·day-1 for athletes who are restricting energy intake and attempting to minimize loss of lean BM. We discuss the underpinning rationale for weight loss in track and field athletes, explaining changes in metabolic pathways that occur in response to energy restriction when manipulating protein intake and training. Finally, this review offers practical advice on protein intakes that warrant consideration in allowing an optimal adaptive response for track and field athletes seeking to train effectively and to lose fat mass while energy restricted with minimal (or no) loss of lean BM.

Sports Foods and Dietary Supplements for Optimal Function and Performance Enhancement in Track-and-Field Athletes.

Athletes are exposed to numerous nutritional products, attractively marketed with claims of optimizing health, function, and performance. However, there is limited evidence to support many of these claims, and the efficacy and safety of many products is questionable. The variety of nutritional aids considered for use by track-and-field athletes includes sports foods, performance supplements, and therapeutic nutritional aids. Support for sports foods and five evidence-based performance supplements (caffeine, creatine, nitrate/beetroot juice, ß-alanine, and bicarbonate) varies according to the event, the specific scenario of use, and the individual athlete's goals and responsiveness. Specific challenges include developing protocols to manage repeated use of performance supplements in multievent or heat-final competitions or the interaction between several products which are used concurrently. Potential disadvantages of supplement use include expense, false expectancy, and the risk of ingesting banned substances sometimes present as contaminants. However, a pragmatic approach to the decision-making process for supplement use is recommended. The authors conclude that it is pertinent for sports foods and nutritional supplements to be considered only where a strong evidence base supports their use as safe, legal, and effective and that such supplements are trialed thoroughly by the individual before committing to use in a competition setting.

Influencia de la música y la compañía sobre la percepción del esfuerzo y el estado de ánimo en corredores amateur / Influence of music and company on perception of effort and mood in amateur runners / Influência da música e da acompanhamento na percepção de esforço e estado de ânimo em corredores amadores

El objetivo del estudio fue analizar la influencia de la música y la presencia de compañía sobre el estado de ánimo y la percepción subjetiva de esfuerzo en corredores amateur. Para la evaluación de los aspectos psicológicos se utilizó el Cuestionario POMS en su versión reducida de 29 ítems y el Test Borg en su versión CR-10. La muestra estuvo compuesta por 12 participantes adultos (6 hombres y 6 mujeres). Los sujetos realizaron tres pruebas de carrera en cinta: en solitario, con música y acompañado, con una velocidad y tiempo controlados. Cada prueba duró 21 minutos. Se midió el estado de ánimo previo y posterior a la tarea así como la percepción de esfuerzo cada siete minutos y la frecuencia cardíaca cada minuto. Esta información permite utilizar las condiciones de práctica de ejercicio físico para asegurar la calidad durante el ejercicio

The aim of the study was to analyze the influence of music and company on mood and rate of perceived exertion in amateur runners. POMS questionnaire in short version (29 items) and Borg test in CR-10 version were employed to measure psychological variables. The sample was composed by 12 participants (6 men and 6 women). Each participant performed three tests: run alone, run with music or run accompanied, with a speed and time controlled. Each test lasted 21 minutes. Mood state was measured before and after each test. The perceived exertion was measured each seven minutes and the heart rate during each minute. Various changes over mood state and rate of perceived exertion were mainly found because of contextual influences (music or company). This information allows the use of practical conditions in order to ensure the efficacy in the exercise and the adherence to the activity program

The effect of massage on acceleration and sprint performance in track & field athletes.

PURPOSE: To examine the acute effects of pre-competition massage on acceleration and sprint performance in collegiate track and field athletes. METHODS: Seventeen collegiate male (n = 9) and female (N = 8) track and field athletes participated in the study. Athletes were assigned to a counterbalanced, repeated measures designed experiment testing four treatment conditions of a pre-competition massage, dynamic warm-up, combination of a massage and warm-up, and a placebo ultrasound. RESULTS: The reliability between treatments was very high (ICC range: 0.94-0.98) and displayed a high internal consistency (Cronbach α = 0.96). Inter-item correlations for treatments were strong at all time intervals (20-m r = 0.74-0.90; 30-m r = 0.87-0.95; 60-m r = 0.88-0.95). There were no significant differences between the four treatments and performance (p = 0.70). Massage decreased 60-meter sprint performance in comparison to the traditional warm-up, although the combination of the massage and warm-up appeared to have no greater difference than the warm-up alone. CONCLUSIONS: Massage prior to competition remains questionable due to a lack of effectiveness in improving sprint performance. Further, pre-competition massage may not be more effective as a pre-event modality, over a traditional warm-up.

Injuries in youth track and field are perceived to have multiple-level causes that call for ecological (holistic-developmental) interventions: A national sporting community perceptions and experiences.

Engaging in competitive sports as a youth can have many health benefits, but recent studies also report a high risk for injury. The long-term purpose of this Swedish research program is to develop a framework for safe track and field training for young athletes (aged 12-15 years). The aim of this study was to establish what is perceived to contribute and cause injuries in youth track and field by compiling the best available experiential knowledge about the underlying factors and use this knowledge to identify appropriate areas to handle these in practical ways. Nine focus group interviews with in total 74 participants and confirming interviews with five individuals were performed in seven Swedish regions. Qualitative research methods were used for data analysis. Injuries in youth athletes were not considered to be strictly the result of individual factors but rather the result of the interactions between factors at different levels. Three major factors emerged as follows: Insufficient knowledge for athletic development in daily practice; shortsighted communities of practice and sports policies not adjusted to youth; and societal health behaviors. The experiential knowledge in the national sporting community suggests that if effective and sustainable injury prevention processes are to be implemented for youth track and field, an ecological (holistic-developmental) approach to injury prevention is needed. Such an approach allows a longitudinal development-focused strategy for prevention that spans an athlete's entire career.

Physical fitness characteristics of adolescent wushu athletes.

BACKGROUND: The purpose of this study was to examine the physical fitness of wushu athletes in junior high schools and to compare their fitness with that of track-and-field and basketball athletes, as well as general junior high school students. METHODS: A total of 120 participants aged 12-15 years were recruited for this study (wushu N.=30; track-and-field N.=30; basketball N.=30; general students N.=30). Participants' height, weight, flexibility, muscle endurance, cardiorespiratory endurance, agility, power, and static and dynamic balance were assessed and compared among sports groups and general students. RESULTS: The results revealed that athletes in the track-and-field, basketball, and wushu groups had significantly better physical fitness than general students. Additionally, the wushu group had significantly better flexibility and static balance than the other three groups. The track-and-field group had better cardiorespiratory endurance than the other groups. The basketball group had the best agility performance. CONCLUSIONS: These findings suggest that flexibility and balance may be most impacted by the practice of wushu in adolescents. Moreover, adolescents who engage in school sports had better physical fitness than that of general students.
