INTRODUCTION: Young athletes of the same chronological age differ in their physical growth, biological maturation, motor performance, and training history. These differences make it difficult for coaches to select athletes. In this study, we investigate whether training experience, biological maturation, physical performance, and technical skills a...

Judo is currently the most practiced combat sport in the world. There is no doubt of its importance for children, adolescents, adults, and seniors. However, due to its inherent complexity, coaches tend to place greater or lesser emphasis only on one of its multiple domains during the judoka formative years. The present study presents a novel develo...

Fourteen male basketball players aged 16.64±.50 years, divided in control group (n=7) and experimental group (n=7), were assessed on free-throw, two-point and three-point shooting performance and on fo...

Nos jogos desportivos coletivos (JDC) as ações do jogo são o resultado das interações dos jogadores no confronto com a oposição dos adversários, ações estas baseadas de forma adequada no espaço e no tempo disponíveis. Trata-se, assim, dos jogadores pro- curarem distinguir num envolvimento em constante mudança e de forma imprevisível as informações...

Although technical skills are a prerequisite for success in basketball, little is known about how they develop over time. In this study, we model the trajectories of technical skill development in young basketball players and investigate the effects of training experience, training volume, body composition, maturity status, physical performance, an...

BACKGROUND: Validated tests for the quality of movement patterns are important to help teachers to assess and induce positive performance changes. However, few tests are available for handball sport skills. AIM: Therefore, we developed and validated a checklist to assess dribbling with a jumping throw. METHOD: First, three handball experts were inv...

O basquetebol requer dos jogadores elevados níveis de força muscular, contudo o seu desenvolvimento é confundido pelos efeitos do crescimento, sobretudo durante a adolescência. Este estudo investigou o timing, intensidade e sequência dos picos de desenvolvimento da força muscular de jovens basquetebolistas quando alinhados pela idade biológica. No...

In this paper, we outline a systematic testing programme developed to help identify excellence in youth basketball players. We examine the links between biological maturation and training experience with anthropometry, body composition, physical performance, technical and tactical skills from five agecohorts, and characterize, in detail, facets of...

This study aimed to (1) estimate age‐at‐mid‐growth spurt (age‐at‐MGS) in Portuguese boys from two different regions—the Azores islands and Viana do Castelo, and (2) identify spurts in a variety of physical fitness (PF) components aligned by age‐at‐MGS in the two samples. A total of 176 (Azores, n = 91; Viana do Castelo, n = 85) boys aged 6 years ol...
