Purpose: This study aimed to develop a stroke effectiveness test in table tennis based on the temporal game structure to assess the ball speed and ball placement of the players, with a purpose to analyze its reproducibility and validity.Methods: Nineteen male table tennis players participated in this study. The test was performed twice during the first session and once during the second session to assess the intrasession and intersession reproducibility, respectively. Moreover, the test was examined on its ability to discriminate between regional (n = 10) and local performance-level (n = 9) players and on the relationship between the test results and the table tennis performance to assess the discriminant and concurrent validity, respectively. In general, the test consisted of 11 simulated rallies of 2–5 balls with the effort and rest ratio of 0.5, and focused on attack with offensive strokes at defensive balls delivered by a robot randomly between the left and right positions on the table.Results: Ball speed, ball placement, and ball speed-ball placement index showed satisfactory reliability (ICC range 0.78–0.96, P < 0.05) and agreement (CV range 2.7–16.2%) outcomes. Additionally, the Bland–Altman plots show the systematic error of the analyses closer to 0, and that most values were within the limits of agreements. Concerning validity analyses, regional players had higher scores of ball placement (+51.3%; P = 0.01, ES = 1.33) and ball speed-ball placement index (+56.1%; P = 0.0009, ES = 1.87) as well as made fewer errors (-25.4%; P = 0.017, ES = 1.20) than local players. Moreover, ball placement (r = -0.79, P = 0.04), ball speed-ball placement index (r = -0.78, P = 0.04), and percentage error (r = 0.88, P = 0.01) presented a strong and significant correlation with table tennis performance. However, ball speed was slightly different between the regional than local players (+1.7%; P = 0.78, ES = 0.13) and this variable was not related to table tennis performance (r = 0.32, P = 0.49).Conclusion: Our findings show evidences that the test is reproducible. Moreover, discriminant and concurrent validity are confirmed for ball placement and ball speed-ball placement index.
Sport coaching in Brazil is a regulated profession that requires higher education qualifications. A degree in physical education (PE) is mandatory since 1998 for those who aspire to work as coaches in the country, which has led universities and professors to play a key role in developing coaches through formal education. Through a personal narrative approach, we—a professor and a PhD candidate—wrote this paper with the purpose of sharing our pathways and reflections in implementing a learner-centred teaching (LCT) approach in an undergraduate coaching course in Brazil, both acting as coach developers (CDs). From a personal and professional growth perspective, as CDs, we acknowledge the relevance of offering such practical experiences along with reflection and peer sharing as crucial steps for practitioners to improve CD expertise in the higher education setting. By reflecting on the potential of a LCT approach in higher education, we demonstrate how LCT strategies can enhance opportunities for student-coaches to gain exposure to meaningful practical coaching situations as a way to better develop their coaching skills within the university environment.
Após os anos 2000, observamos um cenário desafiador ao desenvolvimento de mulheres atletas de basquetebol no Brasil. Em 2010, a Liga de Basquete Feminino (LBF) foi criada para contribuir com a reestruturação da modalidade no país. O objetivo do estudo foi investigar indicativos esportivos e sociodemográficos ao longo da carreira de atletas da LBF 2018. Os dados foram coletados por um questionário online respondido voluntariamente por 57 atletas (média de idade 25,9 ± 6,6 anos). A escola foi o principal local de primeiro contato com a modalidade. A maioria das atletas (79%) foi convocada para seleções e 30% chegaram à seleção adulta. O Sudeste se destacou como a principal região de prática da modalidade. A carreira no basquetebol proporcionou percepção de melhoria de classe social. Por fim, o grupo de atletas apresentou níveis de escolaridade mais altos do que a média da população brasileira.
O objetivo deste ensaio é discutir a formação inicial de treinadores(as) esportivos no Brasil em cursos de bacharelado em Educação Física e Ciências do Esporte. Apresentamos estudos da Educação Física e Ciências do Esporte sobre a formação inicial, e o projeto político pedagógico de Ciências do Esporte da Universidade Estadual de Campinas – Unicamp, um dos dois únicos no Brasil e fortemente ancorado na Pedagogia do Esporte. O curso de Ciências do Esporte mostra uma ênfase nos conhecimentos específicos do esporte. Os discentes e egressos do curso de Ciências do Esporte da Unicamp apresentam maior interesse no treino esportivo, enquanto estudos com egressos da Educação Física apontam a área da saúde. A estrutura curricular e o interesse de atuação em cada curso, sinalizam que a formação de treinadores(as) é mais valorizada e específica no bacharelado em Ciências do Esporte.
Este trabalho investigou a eficiência dos fundamentos e ações em função do tempo durante os Jogos Olímpicos de 2016. Os dados foram coletados através da observação dos vídeos de cinco jogos (três derrotas e duas vitórias). As médias dos arremessos de 2 pontos e passes certos parecem ser um fator muito determinante nos jogos que o Brasil venceu. Entretanto a média de turnovers, arremessos de 2 e 3 pontos errados, lances livres errados, reposição de bola errada e faltas defensivas foram fatores que podem ter influenciado nas derrotas do Brasil. A análise dos períodos positivos e negativos irá trazer mais informações sobre esses indicadores de rendimento
