RESUMO
BACKGROUND: The exhaustive series of tests undergone by young athletes of Olympic rowing prior to important competitions imply loads of physical stress that can ultimately impact on mood and motivation, with negative consequences for their training and performance. Thus, it is necessary to develop a tool that uses only the performance of short distances but is highly predictive, offering a time expectancy with high reliability. Such a test must use variables that are easy to collect with high practical applicability in the daily routine of coaches. OBJECTIVE: The objective of the present study was to develop a mathematical model capable of predicting 2000 m rowing performance from a maximum effort 100 m indoor rowing ergometer (IRE) test in young rowers. METHODS: The sample consisted of 12 male rowing athletes in the junior category (15.9 ± 1.0 years). A 100 m time trial was performed on the IRE, followed by a 2000 m time trial 24-h later. RESULTS: The 2000 m mathematical model to predict performance in minutes based on the maximum 100 m test demonstrated a high correlation (r = 0.734; p = 0.006), strong reliability index (ICC: 0.978; IC95%: [0.960; 0.980]; p = 0.001) and was within usable agreement limits (Bland -Altman Agreement: -0.60 to 0.60; 95% CI [-0.65; 0.67]). CONCLUSION: The mathematical model developed to predict 2000 m performance is effective and has a statistically significant reliability index while being easy to implement with low cost.
RESUMO
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.

ABSTRACT The scientific evidence on the profile of trampoline gymnastic athletes is scarce. Considering that the individual trampoline is an Olympic sport, it is important to investigate the characteristics of these athletes in Brazil. The aim of this study was to evaluate anthropometric, physical-motor, maturational, socio-environmental indicators and the sporting potential of Brazilian trampoline gymnasts, investigating differences between age categories. There were 147 athletes participating who competed in the State and Brazilian Championship of Trampoline Gymnastics by Age Group in 2017-2018. A multidimensional battery of tests was carried out, comparing the indicators collected between the categories 9 to 10 years, 11 to 12 years, 13 to 14 years, 15 to 16 years and 17 years or older. The coaches (n = 20) assessed the sporting potential of their gymnasts, in relation to the expectation of success in the future. The results showed statistically significant differences in body size and composition, somatotype, handgrip strength, countermovement jump, flexibility and sporting potential among athletes of different age categories, in both sexes. In addition, 30% of gymnasts showed high sporting potential, according to the perspectives of the coaches. It is concluded that the multidimensional indicators related to the sporting potential of Brazilian trampoline gymnasts vary according to the age category. This study is a pioneer in characterizing the profile of the elite Brazilian trampoline gymnast, using a dynamic approach related to the sporting talent.
RESUMO A evidência científica sobre o perfil de atletas de ginástica de trampolim é escassa. Considerando que o trampolim individual é uma modalidade olímpica, torna-se importante investigar as características desses atletas na realidade brasileira. O objetivo deste estudo foi avaliar indicadores antropométricos, físico-motores, maturacionais, socioambientais e o potencial esportivo de ginastas de trampolim brasileiros, investigando diferenças entre as categorias etárias. Participaram 147 atletas que disputaram o Campeonato Estadual e Brasileiro de Ginástica de Trampolim por Idades em 2017-2018. Foi realizada uma bateria de testes multidimensional, comparando os indicadores coletados entre as categorias 9-10 anos, 11-12 anos, 13-14 anos, 15-16 anos e 17 anos ou mais. Os treinadores (n = 20) avaliaram o potencial esportivo dos seus ginastas, em relação a expectativa de sucesso no futuro. Os resultados mostraram diferenças estatisticamente significantes no tamanho e composição corporal, somatotipo, força de preensão manual, salto contramovimento, flexibilidade e no potencial esportivo entre os atletas de diferentes categorias etárias, em ambos os sexos. Além disso, 30% dos ginastas apresentaram elevado potencial esportivo, segundo a opinião dos treinadores. Conclui-se que os indicadores multidimensionais relacionados ao potencial esportivo dos ginastas de trampolim brasileiros variam em função da categoria etária. Este estudo é pioneiro na caracterização do perfil do ginasta de trampolim brasileiro de elite, utilizando uma abordagem dinâmica relacionada ao talento esportivo.

Resumo O objetivo deste estudo foi verificar a associação entre nível de desempenho técnico-tático de jogadores e a classificação competitiva em categorias de formação do voleibol. Participaram 271 atletas finalistas do campeonato estadual catarinense de 2010. As ações técnico-táticas foram analisadas conforme o Instrumento de Avaliação do Desempenho Técnico-Tático (IAD-VB) de Collet et al. (2011). Para análise dos dados, recorreu-se à regressão logística multinomial com p ≤ 0,001. Os resultados evidenciaram que as equipes que apresentaram melhor desempenho técnico-tático geral obtiveram as primeiras classificações no campeonato. O nível de desempenho nos componentes tomada de decisão e eficácia também evidenciou associação positiva com a classificação final do campeonato.
Abstract The aim of this study was to verify the association between technical and tactical performance and the competitive classification of young athletes in volleyball. Participated 271 athletes finalists in the Santa Catarina state championship 2010. The technical-tactical actions were analyzed by Instrument of Performance Assessment Technical-Tactical (IAD-VB) of Collet et al. (2011). For data analysis was used a multinomial logistic regression with p <0.001. The results revealed that teams performed better technical-tactical obtained the first overall ratings in the league. The level of performance in components decision making and effectiveness is associated too with the championship classification.
