We examined whether participation and individual performance in the under-18 Euroleague Next Generation Tournament (NGT) predicted a future contract with an NBA, Euroleague, or Eurocup squad. Data from 1446 players between 2002–2003 and 2011–2012 seasons were considered. We considered information about each player, including country, the number of games played, and performance index rating (PIR). We tracked the players’ highest club level attained in their adult careers. We used a multilevel ordinal regression with a cumulative model in a fully Bayesian framework to examine the probability of the players playing in the NGT attaining the NBA, Euroleague, or Eurocup. Furthermore, we explored in the model if PIR in the NGT was a relevant predictor of achieving the highest club level in adult careers. From the total sample, only a very small percentage attain the NBA (20 in 1446, 1.4%), Euroleague (103 in 1446, 7.2%), and Eurocup (60 in 1446, 4.2%). The results highlight that a very sma...

The purpose of this study was to investigate the hematological and inflammatory responses to 4 maximal high-intensity protocols, considering energy expenditure in each test. 9 healthy volunteers performed 4 high-intensity exercise tests of short [Wingate (WANT); Repeated-sprints (RSA)] and long durations [Continuous VO2 test (VCONT); intermittent VO2 test (VINT)] in a cycle-ergometer, until exhaustion. Hematological parameters and IL-6, IL-10 and creatine kinase (CK) levels were determined before (PRE), POST, 30 min, 1, 2, 12 and 24 h after the end of the protocols. Additionally, energy expenditure was determined. Leucocytes, erythrocytes and lymphocytes increased at POST and returned to PRE values at 30 min for all protocols. Lymphocytes had a second decreased at 2 h and granulocytes increased at 2 h when compared to PRE. Both variables returned to PRE values between 12-24 h into recovery. The magnitude of response for IL-6 was greater in VINT and for IL-10 in VCONT. There was no a...

There is a need for educational support structures to empower parents in sustaining talented athletes pursuing academic and sports careers (e. g., dual career). The present work describes the participatory design used to develop a series of educational resources and the subsequent iterations used to evaluate the content of the EMPATIA online education programme for parents of dual-career athletes. Following an ethnographic approach, the project team (18 dual-career experts) engaged in four iterations (i.e., rounds) planned to develop (rounds 1 and 2) educational material from preliminary evidence (systematic literature review) and eminence (focus groups and concept mapping) knowledge and to evaluate the educational programme (round 3 and 4) engaging end users (n = 76) and other stakeholders (9 dual-career experts). The EMPATIA programme was developed and organized in four modules labeled after macro-aspects, parents could ask about dual career: “Why” (the definition and challenges o...

We hypothesized that student-athletes’ athletic identity and motivation are influenced by their own institutions sport policies. The aim of the study is twofold: a) to validate a measure of athletic identity among Portuguese college students; b) to analyze the effects of 3 different types of college policies on identity and motivation. This study used a quantitative design. 201 Portuguese student-athletes answered to two questionnaires, BIMS (Baller Identity Measurement Scale) and SAMSAQ (Student Athletes Motivation towards Sports and Academics Questionnaire). To comparative purposes, three types of university were considered according to their institutions’ sport policies: type 1 (i.e sport organized exclusively by higher education institutes (HEIs)), type 2 (i.e organized by HEIs and/or student associations) and type 3 (i.e organized outside the HEIs). The CFA showed the adjustment of the model of BIMS with two factors for Portuguese student-athlete (emotions and exclusivity) (CFI...

BackgroundDespite the fact that an educational programme for parents of youth tennis players has been launched recently, there is a need to empower parents of athletes in sustaining the combination of education and sport careers (i.e., dual career) of their talented and elite athletes across sports. The aim of this study was to explore the parents’ view of their role as dual career supporters and their need for educational support in this area.MethodsIn total, 115 parents (F = 49, M = 66) of athletes (14–23 yrs) engaged in full time academic education (high school/university) and competitive (e.g., National, International) sports (individual = 12, team = 9) in five European Member States (e.g., France, Ireland, Italy, Portugal, Slovenia) took part in national workshops. The workshops involved discussing five themes and agreeing statements relevant to assist parents supporting their children as dual career athletes: 1) the athletes’ needs; 2) the sports environment; 3) the academic e...

Relative age effect (RAE) is considered to bias the selection of young athletes and a cause of exclusion of many participants. The goal of the study was to unveil the effects of the birth quarter on physical performances and a set of psychological constructs in the age groups corresponding to the specialization years. A set of surveys with cross-sectional data collected from 2015 to 2019 in youth basketball was used. Three hundred and twenty-seven Brazilian players (127 females, 100 males), mean age 14.0 years, participated in the study. Counter-movement jump, line-drill, yoyo intermittent test, achievement goals, motivation for deliberate practice, and enjoyment were measured. Bayesian multilevel regression was performed. RAE was observed but its advantages did not persist and did not differentiate the players in the variables under scrutiny. The only predictor of athletic and psychological outcomes was chronological age. The initial advantage that triggered the coaches' decisi...

We examined the influence of coaches on sources of enjoyment of youth basketball players accounting for differences in chronological age, biological maturity status and years of training experience. Fifty-eight male basketball players aged 9.5 to 15.5 years were considered from a youth club. Three coaches supervising yearly age group teams from under 11 to under 15 teams were considered. Variables included chronological age, estimated age at peak height velocity, years of training experience, stature, body mass and sitting height by anthropometry; Sources of Enjoyment in Youth Sport Questionnaire was used. Multilevel modelling was used to partition variance between groups and control the influence of age and maturity status on enjoyment. Variance partition coefficients derived from multilevel null models showed a substantial variation by coach for age, maturity status and body dimensions. For the sources of enjoyment dimensions it was apparent an influence of the coach mostly for po...

Background This study aimed to use a concept mapping methodology to develop a European framework of the needs of parents/guardians (P/G) for supporting athletes combining sport and education (dual career, DC). Methods By means of a concept mapping methodology, 337 French, Irish, Italian, Portuguese, and Slovenian parents sorted and rated 80 potential statements associated to parenting DC athletes. Results Five distinct clusters emerged: 1. P/G’ roles, needs and awareness to support athletes, including 22 statements (mean:3.7; range: 3.2–4.2 pt); 2. Requirements for effective planning of DC pathway, including 19 statements (mean:3.7; range: 3.2–4.5 pt); 3. Educational opportunity, including 13 statements (mean:3.5; range: 3.1–4.0 pt); 4.

We considered identity variation among Brazilian university student-athletes in relation to their gender, sport type, competition level, and university type. Participants were 506 student-athletes (219 males and 287 females) from public and private Brazilian universities, competing in team and individual sports, at local, state, and national levels. We used multilevel regression and poststratification to estimate each participant’s identity from the aforementioned variables. Gender and sport type were not associated with any substantial identify variation, but there were higher values on Baller Identity Measurement Scale dimensions for student-athletes from public versus private universities, and student-athletes competing at the highest level had lower Baller Identity Measurement Scale values compared to peers competing at lower levels. Overall, university type and sport competitive level were the contextual factors that most influenced Brazilian student-athletes’ identities.

This study examined the variation of student-athletes’ identity and motivation across Portuguese and Brazilian universities, accounting for variation in gender, student-athletes’ training hours per week, sports level, student-athletes status within each university, and university type. We initially established the validity of the Baller Identity Measurement Scale questionnaire and the Student-Athletes’ Motivation toward Sports and Academics Questionnaire-based observations among 441 Brazilian and Portuguese student-athletes. Then, the validated version of the questionnaires was applied to a total sample of 765 student-athletes from Brazil (n= 568) and Portugal (n = 197). We further considered individual (hours of training and student-athlete status) and contextual characteristics (university type and country). Multilevel regression and poststratification were used to estimate each student-athlete identity and motivation as a function of his or her individual and contextual character...

Youth sporting activities have been explored as a way to impact positive personal transformation and development, glaringly demonstrated by world-wide investments in public policies, programs, and projects. We studied positive effects of participation in sports on the developmental assets of 614 adolescents (13.1 ± 1.7 years) actively engaged in extracurricular sport programs targeted at socially disadvantaged youths, from five municipalities across five states of the southern, south-eastern and north-eastern regions of Brazil. Participants responded to a developmental assets questionnaire designed to capture sociodemographic and human development data. Multilevel logistic regression was used to explore associations between years of participation in sport and human development indicators, controlling for age and sex. Our results showed that the quality of the young people's support network and duration of program participation positively influenced sport participation, which, in...

The interaction of multiple influences on the path to sport success is not yet fully understood by sport scientists. In this study, we examined variation in body size, functional capacities and motivation for achievement, competitiveness and deliberate practice of youth basketball players associated with differences in biological maturity status, chronological age and years of training experience. Reflecting the importance of interactive effects, we examined the relationships between the psychological variables and functional capacities. Fifty-eight male basketball players aged 9.5 to 15.5 years were considered. Variables included chronological age, estimated age at peak height velocity, stature, body mass and sitting height by anthropometry; the Work and Family Orientation and Deliberate Practice Motivation Questionnaires were also used. Finally, the Line Drill test and Yo-Yo Intermittent Recovery level 1 (Yo-Yo IR1) tests were used as functional capacities indicators for basketbal...

The present study examined extracurricular sport participation variables and developmental context in relationship to perceived self-efficacy among underserved adolescents. Participants ( n = 821, 13.6 ± 1.5 years) completed the Youth Experience in Sport questionnaire and General Self-Efficacy Scale. We used the Human Development Index (HDI) to characterize developmental contexts. Multilevel regression models were used to explore the relative contributions of age, sex, years of participation in extracurricular sport, HDI, and perceived positive experience in sport. Our results highlight that positive experience alone and in interaction with length of participation in the program fostered perceived self-efficacy. Participants from higher HDI contexts remained longer in the program. An implication of our research is that variables linked to positive sport experiences and perceived self-efficacy can be used as markers to evaluate the outcomes and impact of sport participation programs ...

The study examined the validity of the Line Drill test (LD) in male adolescent basketball players (10-15 years). Sensitiveness of the LD to changes in performance across a training and competition season (4 months) was also considered. Age, maturation, body size and LD were measured (n = 57). Sensitiveness of the LD was examined pre- and post-competitive season in a sub-sample (n = 44). The time at each of the four shuttle sprints of the LD (i.e. four stages) was modelled with Bayesian multilevel models. We observed very large correlation of performance at stage 4 (full LD protocol) with stage 3, but lower correlations with the early LD stages. Players' performance by somatic maturity differed substantially only when considering full LD protocol performance. Substantial improvements in all stages of the protocol were observed across the 4-month competitive season. The LD protocol should be shortened by the last full court shuttle sprint, remaining sensitive to training exposure,...

O artigo procurou investigar a adesão de jovens do sexo masculino da categoria sub-13 no futsal de uma escola da rede particular de ensino e em um clube esportivo da cidade de Curitiba. Os dados foram coletados através de entrevistas com 17 participantes: pais, professor/técnico e alunos/atletas e, também realizadas observações assistemáticas por seis meses nos locais de treinos e jogos das equipes. Nossas principais conclusões são que os alunos da escola jogam futsal porque o jogo acontece entre amigos. No clube, o principal fator de adesão é a expectativa de profissionalização no futebol de campo do mesmo clube, visando recompensa financeira.

In the present study we examined the age- and maturity-associated variation on body size and functional capacities in 47 adolescent female basketball players. Also, we examined the relative contribution of growth and maturity status to functional capacity between player variation. Data included chronological age, age at menarche, years of training experience; body dimensions; countermovement jump, Line drill test and Yo-Yo intermittent recovery test – level 1. Bayesian multilevel modelling was used to estimate the independent effects of age, maturity status, years of training experience and body size on functional capacity indicators. Players were, on average, advanced in maturity status, with a mean age at menarche of 11.20 years (1.32 years). Age-associated variation in age at menarche, body size and functional performance was present. No substantial maturity-associated variation was observed for stature and functional capacities, but late maturing players appeared to be less expe...

Background: Early sport specialization has increased its popularity mostly based on the deliberate practice theory premises. In this study, we examined the influence of the age of onset of deliberate basketball practice on body size, functional performance (countermovement jump, line drill and yo-yo intermittent recovery level 1), motivation for achievement and competitiveness, motivation for deliberate practice and sources of enjoyment among young Brazilian basketball players. In addition, we adjusted for the influence of gender, age group, maturity status and state basketball federation on the outcomes. Methods: The sample included 120 female and 201 male adolescent basketball players aged 14.0 (1.7) years, on average. We grouped players by the age of onset of deliberate basketball practice as related to biologic maturation milestones (pre-puberty deliberate practice onset, mid-puberty deliberate practice onset and late-puberty deliberate practice onset).

Brazil has been the benchmark for volleyball performance for at least two decades, providing a unique context to examine expertise development. This study examined the variation in body size, functional capacities, motivation for achievement, competitiveness, and deliberate practice of youth volleyball players associated with differences in biological maturity status, chronological age, and accumulated deliberate volleyball practice, adopting a Bayesian multilevel modeling approach. We considered 68 female and 94 male adolescent players (14.2 years, 90% confidence interval: 12.7 to 16.0). Players were grouped by the onset of deliberate volleyball practice as related to biologic maturation milestones [pre-puberty deliberate practice onset (12% of the sample), mid-puberty deliberate practice onset (51% of the sample), and late-puberty deliberate practice onset (37% of the sample). There was substantial variation in body dimensions and functional performance by gender. There was no var...

The Deliberate Practice Theory postulates that experts are always made, not born. This theory translated to the youth sport domain means that if an athlete wants to be a real high level performer, he/she needs a deliberate engagement in practice during the specialization years, spending time wisely and always focusing on tasks that challenge the current performance. However, literature suggests that the sport promoting strategies are being maintained despite of the increased demands in the anthropometric characteristics of professional players and demands of the actual professional soccer competitions. On the other hand, the task of the researchers to identify biological variables that can predict performance turned almost impossible. Persistence in activity seems to represent a complex process of conciliation between personal expectations and the climate fostered by others with a progressive reduction of sources of conflict. This underlines the importance of the social environment ...

O objetivo deste estudo foi analisar o processo de formação de jovens futebolistas sob a perspectiva de técnicos de Brasil e Portugal. Oito técnicos participaram do estudo, sendo quatro brasileiros e quatro portugueses. Foi utilizada a entrevista semiestruturada, da qual emergiram quatro categorias. O processo de formação de atletas é diferente entre os países. O contexto social e pedagógico no Brasil passa por diversos departamentos específicos antes de chegar ao técnico, por outro lado, em Portugal o técnico tem mais proximidade com as questões sociais que envolvem os atletas. Uma realidade pode aprender com a outra, a fim de que os atletas se desenvolvam tecnicamente, mas que também desenvolvam outras competências no caso de insucesso no futebol.

A detecção, seleção e promoção de talentos esportivos se constitui como um processo de relevância tanto no âmbito bio-psico-social, quanto no âmbito econômico, visto o impacto que a identificação de atletas de alto nível traz a sociedade. Sendo assim, o presente trabalho teve como objetivo fazer um levantamento acerca da temática, utilizando como método a análise de conteúdo (BARDIN, 1977). O processo é visto por um duplo viés: a lógica mercadológica e humano-holística. Há indícios de prevalência da lógica mercadológica, em que a valorização se dá, essencialmente, pelos capitais futebolísticos, que, por sua vez, apresentam uma difícil reconversão em outros capitais.

The theory of deliberate practice postulates that experts are always made, not born. This theory translated to the youth-sport domain means that if athletes want to be high-level performers, they need to deliberately engage in practice during the specialization years, spending time wisely and always focusing on tasks that challenge current performance. Sport organizations in several countries around the world created specialized training centers where selected young talents practice under the supervision of experienced coaches in order to become professional athletes and integrate onto youth national teams. Early specialization and accurate observation by expert coaches or scouts remain the only tools to find a potential excellent athlete among a great number of participants. In the current study, the authors present 2 of the problems raised by talent search and the risks of such a search. Growth and maturation are important concepts to better understand the identification, selectio...
