ABSTRACT
Vertical jump is an important skill that influences volleyball performance. In this study, we analyzed the relationship between vertical jump performance and birth quartile of Brazilian male youth volleyball players. We calculated chi-square goodness-of-fit tests to compare the athletes' birthdate distributions in quarters of their birth years (Q1, Q2, Q3, and Q4) according to player age categories (U17, U18, U19, and U21). We calculated one-way ANOVAs to compare spike jump and block jump heights of players born in different quarters of the same year. Overall, we found a relative age effect (i.e., more players with birth dates early in the birth year) in U17 (p < .001), U18 (p < .001), U19 (p < .001), and U21 (p = .04). Regarding vertical jump performance, U18 athletes born in Q2 reached higher spike jump heights (p = .006) and block jump heights (p = .002) than athletes born in Q4, and U19 athletes born in Q1 reached higher block jump heights than athletes born in Q3 (p = .049). There were no significant differences in vertical jump performance across birth quartiles among U17 and U21 athletes. Thus, a relative age effect was present in all age categories but not always reflected in vertical jump performance. Volleyball coaches and policymakers are still advised to employ strategies to ensure fairer opportunities for players born later in the year of their eligibility dates, as we found RAE to be sometimes, but not always, related to higher spike or block jump heights even among these older adolescents and young adult athletes.

ABSTRACT Purpose: to investigate genetic recurrence and molecular markers for dyslexia in two candidate genes in the Brazilian population. Methods: a cross-sectional, case-control, observational study, with five single nucleotide polymorphisms (SNPs) studied in DYX1C1 and KIAA0319 genes in 86 subjects with dyslexia and 66 controls, matched for gender and age. SNPs were genotyped using the polymerase chain reaction technique in real time, and distribution of genotypic and allelic frequencies between the groups was analyzed. Results: it was determined that 68% of the subjects with dyslexia present a family history of learning difficulties. The DYX1C1 gene did not demonstrate an association with dyslexia, which was found regarding the rs9461045 marker of the KIAA0319 gene. Conclusion: a family history of learning problems was present in more than two-thirds of the group with dyslexia, indicating that this is an important risk factor. An association with dyslexia in the rs9461045 marker was noted, making the study the first one to show an association of the KIAA0319 gene with dyslexia, in Latin America.
ABSTRACT
Studies on small-sided games (SSG) in team sports have increased in recent decades. However, the literature concerning this training strategy in volleyball is sparse. This study aims to summarize and analyse the scientific evidence on SSG in volleyball. For this purpose, electronic searches were conducted in August 2021 in PubMed, Scielo, ScienceDirect, Scopus, SPORTDiscus, and Web of Science databases. As result, a total of 22 studies (3 cross-sectional, 7 quasi-experimental, and 12 randomized controlled trial) that used SSG in volleyball were included in the qualitative synthesis after applying the eligibility criteria. Despite the few studies available for each outcome, our results suggest that the SSG can be used as a methodological resource for volleyball teaching and training of educational, recreational, and high-performance character. In conclusion, the use of SSG in volleyball is a pedagogical and training alternative with positive effects on populations with different levels of training (school and university students, recreational adult players, and athletes) considering instructional approaches, sport knowledge, participation in Physical Education classes, health markers, physical fitness, and physiological, psychological, and tactical-technical variables. However, more studies need to be carried out using SSG in volleyball in different contexts, with different manipulations and variables.
ABSTRACT
Abstract Introduction: The relative age effect is prevalent in different elite team sports. However, little is known about this phenomenon in high-level adult male futsal players. Aim: The present study aimed to investigate the prevalence of relative age effect in Brazilian male elite futsal players, and its relationship with playing position and goals scored on Brazil National Futsal Leagues (BNFL) from 2016 to 2020. Methods: The distribution of birth dates, playing positions, and goals scored by male participants of the Brazil National Futsal Leagues were analyzed. Chi-squared tests were used to analyze the birth dates distribution based on quarters and semesters of the year, according to playing position (defender, winger, pivot, and goalkeeper) and scoring performance (high and low). Results: The overall analysis indicated that the relative age effect is prevalent on the pool of athletes analyzed. However, this effect was position-dependent, since relatively older athletes were overrepresented only in wingers and defenders playing positions. On the other hand, scoring performance was not associated with the relative age effect, since this effect was found in both performance levels. Conclusion: Relative age effects are prevalent in Brazilian male elite futsal athletes, especially for defenders and wingers. Considering the high level of competitiveness for spots in elite futsal teams, coaches and sports administrators must be educated about the prevalence of the relative age effect in this sporting context. This is necessary in order to reduce the inequalities generated by age categories based on arbitrary cut-off dates, which may reduce potential talent loss.

ABSTRACT The purpose of this study was to describe weekly variations in the type and duration of training, as well as wellness-related parameters, in elite volleyball players. Twenty-four youth elite volleyball players from the French national team (age: 17.8 ± 1.0 y.o.) were monitored daily, and the type of training, training duration, participation in matches, and wellness status were measured over 22 weeks. Volleyball training duration varied from 100 to 510 minutes per week, while strength and conditioning training duration varied from 97 to 262 minutes per week. Fatigue levels varied from 1.5 to 2.8 A.U., and delayed onset muscle soreness (DOMS) varied from 1.5 to 2.5 A.U. Large positive correlation were found between sleep and match duration (r = 0.64) and between stress and weekly volume (r = 0.52). Additionally, moderate positive correlation were found between fatigue and match duration (r = 0.36); between sleep and weekly volume (r = 0.35); between DOMS and match duration (r = 0.43); between stress and strength training (r = 0.42), volleyball training (r = 0.35), and match duration (r = 0.47). The present study revealed natural variations in training volume across the season and moderate dependency between weekly training/match durations and wellness status.
RESUMO O objetivo deste estudo foi descrever as variações semanais no tipo e duração do treinamento, bem como parâmetros relacionados ao bem-estar, em jogadores de elite de voleibol. Vinte e quarto jovens jogadores de elite de voleibol da seleção Francesa (idade: 17,8 ± 1,0 anos) foram monitorados diariamente, e o tipo de treinamento, a duração do treinamento, a participação em partidas e o status de bem-estar foram medidos durante 22 semanas. A duração do treinamento de voleibol variou de 100 a 510 minutos por semana, enquanto a duração do treinamento de força e condicionamento variou de 97 a 262 minutos por semana. Os níveis de fadiga variaram de 1,5 a 2,8 A.U., e a dor muscular tardia (DMT) variou de 1,5 a 2,5 A.U. Correlação positiva grande foi encontrada entre sono e duração do jogo (r = 0,64) e entre estresse e volume semanal (r = 0,52). Além disso, uma correlação positiva moderada foi encontrada entre fadiga e duração da partida (r = 0,36), entre sono e volume semanal (r = 0,35), entre DMT e duração da partida (r = 0,43), entre estresse e treinamento de força (r = 0,42), treinamento de voleibol (r = 0,35), e duração da partida (r = 0,47). O presente estudo revelou variações naturais no volume de treinamento ao longo da temporada e dependência moderada entre treinamento semanal/duração da partida e status de bem-estar.
ABSTRACT
Abstract The aims of this study were: (i) to describe weekly variations of acute load (AL), acute:chronic workload ratio, delayed onset muscle soreness (DOMS), and fatigue; (ii) to analyze variations of weekly workload and well-being in three periods of the season (P1, P2, and P3); and (iii) to analyze the relationships between workload and well-being measures. Fifteen professional basketball players from a first-league European club were monitored throughout the season using the CR-10 Borg scale and the Hooper questionnaire. Weekly AL and acute:chronic workload ratio (ACWR) were weekly calculated for monitoring of the internal load. In addition, DOMS and fatigue values were weekly calculated. Greater AL, DOMS, and fatigue values were found during the early season, and the highest ACWR value was found during the second period. Overall, AL presented large correlations with DOMS (r=0.60) and fatigue (r=0.62). The results of this study indicate that load is higher in the first period and then decreases throughout the season. The results also showed that AL is more closely related to well-being parameters than ACWR.
Resumo O objetivo deste estudo foi: (1) descrever as variações semanais de carga aguda (CA), razão da carga de trabalho aguda:crônica, dor musuclar tardia (DOT) e fadiga; (ii) analisar as variações da carga semanal de trabalho e bem-estar entre três períodos da temporada (P1, P2 e P3); e (iii) analisar as relações entre carga de trabalho e medidas de bem-estar. Quinze jogadores profissionais de basquetebol de um clube de primeira liga Européia foram monitorados ao longo de uma temporada utilizando a escala CR-10 Borg e o questionário de Hooper. A CA semanal e a razão da carga de trabalho aguda:crônica (RCTAC) foram calculadas semanalmente para monitorar a carga interna. Além disso, os valores de DOT e fadiga foram calculados semanalmente. Maiores valores da CA, DOT e fadiga foram ensontrados durante o início da temporada e o maior valor de RCTAC foi encontrado durante o segundo período. No geral, a CA apresentou grandes correlações com a DOT (r = 0,60) e fadiga (r = 0,62). Os resultados deste estudo indicam que a carga é maior no primeiro período e depois diminui ao longo da temporada. Os resultados também motraram que a CA está mais relacionada com os parâmetros de bem-estar do que a RCTAC.
ABSTRACT
ABSTRACT The present study aimed to check if there is an association between fitness performance variables and to analyze the variation of fitness levels between playing positions university soccer players. Twenty university soccer players were selected (20.95 ± 1.84 years; 71.60 ± 11.65 kg; 176.85 ± 7.28 m) divided into defenders, midfielders and attackers. Body composition was assessed in a cross-sectional analysis that correlated fat mass, lean mass and fat-free mass by DXA with the physical capacity tests. The main results of the present study revealed that both 10-m and 20-m accelerations had moderate-to-large correlations with agility tests across the playing positions, however these accelerations were largely inversely correlated with YoYo intermittent recovery test in defenders and largely positively in midfielders. The agility test was moderately correlated with YoYo intermittent recovery test across the different playing positions. In conclusion, there the acceleration and the agility had a positive association with the different positions of the soccer players.
RESUMO O objetivo do presente estudo foi verificar se existe associção entre as variáveis de desempenho físico e analisar a variação dos níveis de aptidão física entre as posições de jogador de futebol universitário. Foram selecionados 20 jogadores de futebol universitário (20,95 ± 1,84 anos; 71,60 ± 11,65 kg; 176,85 ± 7,28 m) divididos em zagueiros, meio-campistas e atacantes. Mensurou-se a composição corporal em uma análise transversal e correlacionou-se a massa gorda, massa magra e massa livre de gordura por meio do DXA com os testes de capacidade física. As principais evidências do presente estudo revelaram que as acelerações de 10 e 20 m tiveram correlações de moderada a grande com o teste de agilidade nas posições de jogo, porém essas acelerações foram inversamente correlacionadas com o teste de recuperação intermitente nos defensores e amplamente positiva nos meio-campistas. O teste de agilidade foi moderadamente correlacionado com o teste de recuperação intermitente YoYo nas diferentes posições de jogo. Em conclusão, a aceleração e a agilidade tiveram uma associação positiva com as diferentes posições dos jogadores de futebol.

Screening instruments can help to characterize the academic and neuropsychological difficulties of individuals with Dyslexia. The aim of this study was to verify whether there would be differences in performance in the Identification of Signs of Dyslexia Test (TISD) when a group of children with Dyslexia was compared other diagnostic groups of children with level 1 Autism Spectrum Disorder (ASD), Intellectual Disability (ID), Attention Deficit/Hyperactivity Disorder, Borderline Intellectual Functioning and Academic Difficulties. Participants were 172 children that had been diagnosed by interdisciplinary teams and average age ranging from 8.75 (SD = 2.21) to 10.14 (SD = 2.36) year-old. Comparison and association analyzes were performed using Univariate Analysis of Variance and Multinomial Logistic Regression, respectively. The results indicated that the ID and ASD groups presented more impaired performances. Additionally, the TISD was sensitive enough to identify differences between the Dyslexia and ASD groups, with the latter presenting worse performance. However, with the other groups, such differences were not observed. Complementary studies, with larger samples, are necessary, considering the effects of other variables associated with the disorders studied.

O objetivo do estudo foi de verificar se haveria diferenças de desempenho no Teste para Identificação de Sinais de Dislexia (TISD) quando um grupo de crianças com Dislexia fosse comparado a outros grupos diagnósticos de crianças com Transtorno do Espectro Autista, nível 1 (TEA), Deficiência Intelectual (DI), Transtorno de Déficit de Atenção/Hiperatividade, Funcionamento Intelectual Limítrofe e Dificuldade Escolar. Participaram 172 crianças, com diagnóstico provindos de equipes interdisciplinares e médias de idade que variaram entre 8.75 (DP = 2.21) e 10,14 (DP = 2.36) anos. Foram realizadas análises de comparação e associação por meio da Análise Univariada da Variância e da Regressão Logística Multinomial, respectivamente. Os resultados indicaram que os grupos DI e TEA apresentaram desempenhos mais prejudicados. Adicionalmente, o TISD foi sensível para identificar diferenças entre os grupos Dislexia e TEA, com pior desempenho desse último. Entretanto, com os outros grupos, tais diferenças não foram observadas. Estudos complementares são necessários considerando maior casuística e efeitos de outras variáveis associadas aos transtornos estudados.

OBJECTIVE: To investigate if students with developmental dyslexia (DD) have more behavior problems and depressive symptoms than students without learning difficulties. METHOD: Participants were 61 students, aged 7-14 years, including 31 with interdisciplinary DD diagnosis and 30 without learning disabilities. We collected data from parents, using the children's behavior checklist (CBCL), and from students, using the children's depression inventory (CDI). RESULTS: The DD group had higher CBCL averages for anxiety, depression, withdrawal, rule-breaking behaviors, aggressiveness, and social, attentional and thought problems. They also showed higher results for the internalizing and externalizing categories, others and total. In the CDI, DD students had higher averages for total score and for the following symptoms: negative self-evaluation, guilt, suicidal thoughts, feeling concern, performance comparison, sleeping difficulties, fatigue, and problems in interacting with peers at school. CONCLUSIONS: We discuss the results in terms of implications for DD diagnosis and intervention. Parent reports indicate a higher frequency of behavior problems in students with DD diagnosis. Those students also demonstrate more symptoms of depression than students without learning difficulties.
ABSTRACT
Abstract The aim of the present study was to evaluate the age and inter- and intra-position differences in the anthropometric variables and physical performance in young female players of Brazilian women's volleyball. Fifty-eight female volleyball players participated, divided into 3 age groups: (a) 14 and under (n=20; mean age = 12.6±0.7 years), (b) between 14 and 17 (n=31; mean age = 15.6±1.2 years), and (c) over 17 (n=7; mean age = 18.9±0.9 years). In addition, the players were also divided according to their positions: setters (n=7), opposites (n=13), passer-hitters (n=17), middle blockers (n=12) and liberos (n=9). Anthropometric characteristics, flexibility, strength / resistance abdominal muscles, pushups, explosive power of the arms, jumping abilities, shuttle run and 20-m sprint tests were evaluated. Analyses showed differences among age and playing positions for the height and bone mass (p<0.05). In the fitness assessment, no differences were found between playing positions (p>0.05). However, differences were found among for age groups horizontal jump, shuttle run and 20-m sprint, with players >17 performing better than <14 and between 14-17 years of age (p<0.05). These results demonstrated that the height, bone mass and horizontal jump, shuttle run and 20-m sprint are age dependent, while physical performance independent on the playing positions.
Resumo Objetiva-se avaliar a idade e as diferenças inter e intra-posições nas variáveis antropométricas e no desempenho físico de jovens jogadoras do voleibol feminino brasileiro. Participaram 58 atletas femininas de voleibol, divididas em 3 grupos por faixa etária: (a) até 14 (n = 20; idade média = 12,6 ± 0,7 anos), (b) entre 14 e 17 (n = 31; média de idade = 15,6 ± 1,2 anos); (c) acima de 17 (n = 7; idade média = 18,9 ± 0,9 anos). Além disso, os jogadores também foram divididos de acordo com suas posições: levantadores (n = 7), opostos (n = 13), passadores (n = 17), bloqueadores (n = 12) e líberos. (n = 9). Foram avaliadas as características antropométricas, flexibilidade, força / resistência dos músculos abdominais, flexões, poder explosivo dos braços, habilidades de salto, corrida e corrida de 20 m. As análises mostraram diferenças entre idade e posições de jogo para a altura e massa óssea (p<0,05). Na avaliação da aptidão, não foram encontradas diferenças entre as posições de jogo (p>0,05). No entanto, foram encontradas diferenças entre os grupos etários: salto horizontal, corrida e corrida de 20 m, com os jogadores acima de 17, com desempenho melhor que menores que 14 e entre 14 e 17 anos de idade (p<0,05). Estes resultados demonstraram que a altura, a massa óssea e o salto horizontal, o deslocamento e a velocidade de 20m são dependentes da idade, enquanto que o desempenho físico é independente das posições de jogo.

Abstract In Brazil, there is a lack of valid instruments for screening for Developmental Dyslexia (DD) and so the aim of this study was an in-depth investigation of evidence of validity based on the relations with external variables for the Identifying Signs of Dyslexia Test (TISD). More specifically, it seeks to investigate the validity of the criterion, i.e. whether such instruments would be capable of identifying this diagnosis. The research involved comparing two samples: (a) children with DD diagnosis (n = 15) and (b) children without complaints of reading and writing difficulties (n = 146). It was found that in all the subtests of which the instrument is made up (reading, writing, visual attention, calculation, motor skills, phonological awareness, rapid naming, short term memory) there were significant differences between the groups, and in the test total. The results suggest that the TISD was able to identify the group with DD, evidencing the validity of the criterion for this instrument.
Resumo No Brasil há escassez de instrumentos validados para triagem da Dislexia do Desenvolvimento (DD), dessa forma, o presente estudo objetivou investigar mais profundamente evidências de validade baseadas nas relações com variáveis externas para o Teste para Identificação de Sinais de Dislexia (TISD). Especificamente, buscou-se investigar a validade de critério, ou seja, se tal instrumento seria capaz de identificar esse diagnóstico. A pesquisa envolveu a comparação de duas amostras: (a) crianças com diagnóstico de DD (n = 15) e (b) crianças sem queixas de dificuldades em leitura e escrita (n = 146). Verificou-se que em todos os subtestes que compõem o instrumento (leitura, escrita, atenção visual, cálculo, habilidades motoras, consciência fonológica, nomeação rápida, memória de curto prazo) houve diferenças significativas entre os grupos, bem como no total do teste. Os resultados sugeriram que o TISD foi capaz de indicar o grupo com DD, o que evidencia validade de critério para tal instrumento.

The descriptors were "attention deficit hyperactivity disorder" and "adulthood" and "impacts" or "consequences". The inclusion criteria were: full-text articles, published in Portuguese, English or Spanish. The articles that did not respond the questions research were excluded. RESULTS: In total, 776 studies were found, and 15 studies were selected to analysis (five reviews and ten empirical studies). The main impacts evidenced by the studies were affective emotional development, professional performance, financial management, marital relationship and parental role. CONCLUSION: Adults with ADHD have negative and significant impacts on different aspects of their development and can be mediated by deficits in executive functions. Early diagnosis and appropriate interventions can minimize the impacts.
ABSTRACT
RESUMO Objetivo: comparar sinais sugestivos de estresse entre crianças com transtornos de aprendizagem (com e sem intervenção fonoaudiológica) e em crianças sem qualquer dificuldade escolar, além de verificar sinais sugestivos de estresse entre os grupos de acordo com o sexo dos participantes. Métodos: participaram do estudo 25 crianças com transtorno de aprendizagem, 10 com diagnóstico, porém sem intervenção e 15 em intervenção fonoaudiológica, e 25 crianças sem queixas de aprendizagem. Em todos os grupos foi aplicada uma escala de estresse infantil. Resultados: observou-se que 43% das crianças com transtorno de aprendizagem sem intervenção, 56% das crianças com transtorno de aprendizagem em terapia e 83% das crianças sem o transtorno, apresentaram sinais de alerta. Estas diferenças não foram estatisticamente significantes. Também não foi encontrada esta diferença entre os sexos. Conclusão: nos dois grupos houve alta frequência de sinais de alerta para o estresse infantil, mostrando que este pode não ser um fator determinante no desempenho escolar na amostra estudada.
ABSTRACT Purpose: to compare suggestive signs of stress in children with learning disorders (with and without speech-language intervention) and in children without learning problems, and to identify suggestive signs of stress among groups according to the gender of the participants. Methods: the study included 25 children with learning disorder. Of these children, 10 were diagnosed, but without intervention and 15 children were receiving speech-language intervention. Also 25 children without any learning problems participated in the study. In all groups, a children's stress scale was applied. Results: it was observed that 43% of children with learning problems without intervention, 56% of children with learning problems in intervention and 83% of children without learning problem, showed warning signs for child stress. These differences were not statistically significant. In addition, were not found differences between genders. Conclusion: in all groups, there was a high frequency of warning signs for child stress, showing that this may not be a determining factor in academic achievement in the study sample.
ABSTRACT
The objective of this study was to characterize the children referred to the Neuro-Learning Disorder Clinic at the Public Hospital of the Universidade Estadual de Campinas (State University of Campinas) in 2010 focusing on the demographics, parents' concerns, and the diagnoses given by the health care professionals. A total of 203 male and female children and young people, aged 4-17 years old, attending kindergarten to high school were analyzed. The children that were referred due to school-related problems underwent interdisciplinary evaluations aiming to establish a diagnosis. After thorough evaluation, the children were treated according to their specific needs. The study sample was predominately comprised of males (67.0%), fifth graders with average age of 10 years and 11 months. The main problems identified were global learning difficulties and inattention. The evaluation results indicated 43.8% of pedagogy-related learning difficulties and 32.2% of intellectual disability issues. The findings corroborate those of other studies on the characterization of behavior and school-related problems of children and adolescents in specialized centers. The results obtained emphasize the importance of an interdisciplinary team work to evaluate school-related problems.
O objetivo do trabalho foi caracterizar as crianças encaminhadas ao Ambulatório de Neuro-Dificuldades de Aprendizagem da Universidade Estadual de Campinas em 2010. Foram analisados dados de 203 crianças e jovens, de ambos os gêneros, com faixa etária entre 4 e 17 anos de idade, cursando do ensino infantil ao médio. As crianças encaminhadas com queixas escolares passaram por avaliações interdisciplinares com objetivo diagnóstico e após o processo avaliativo foram devidamente encaminhadas para intervenções específicas conforme o caso. Na amostra de crianças atendidas houve maior frequência do gênero masculino (67,0%), uma idade média de 10 anos e 11 meses, com maior número de pessoas cursando o 5ª ano. As principais queixas foram dificuldades globais de aprendizagem e desatenção. Dos resultados das avaliações, 43,8% foram de dificuldades escolares de ordem pedagógica e 32,2% de deficiência intelectual. Os achados obtidos corroboram outros estudos de caracterização de queixas escolares e comportamentais de crianças e adolescentes em centros especializados. Os dados também reforçam a importância da avaliação de equipe interdisciplinar em um processo de investigação das queixas escolares.

The objective of this study was to characterize the children referred to the Neuro-Learning Disorder Clinic at the Public Hospital of the Universidade Estadual de Campinas (State University of Campinas) in 2010 focusing on the demographics, parents' concerns, and the diagnoses given by the health care professionals. A total of 203 male and female children and young people, aged 4-17 years old, attending kindergarten to high school were analyzed. The children that were referred due to school-related problems underwent interdisciplinary evaluations aiming to establish a diagnosis. After thorough evaluation, the children were treated according to their specific needs. The study sample was predominately comprised of males (67.0%), fifth graders with average age of 10 years and 11 months. The main problems identified were global learning difficulties and inattention. The evaluation results indicated 43.8% of pedagogy-related learning difficulties and 32.2% of intellectual disability issues. The findings corroborate those of other studies on the characterization of behavior and school-related problems of children and adolescents in specialized centers. The results obtained emphasize the importance of an interdisciplinary team work to evaluate school-related problems.(AU)
O objetivo do trabalho foi caracterizar as crianças encaminhadas ao Ambulatório de Neuro-Dificuldades de Aprendizagem da Universidade Estadual de Campinas em 2010. Foram analisados dados de 203 crianças e jovens, de ambos os gêneros, com faixa etária entre 4 e 17 anos de idade, cursando do ensino infantil ao médio. As crianças encaminhadas com queixas escolares passaram por avaliações interdisciplinares com objetivo diagnóstico e após o processo avaliativo foram devidamente encaminhadas para intervenções específicas conforme o caso. Na amostra de crianças atendidas houve maior frequência do gênero masculino (67,0%), uma idade média de 10 anos e 11 meses, com maior número de pessoas cursando o 5ª ano. As principais queixas foram dificuldades globais de aprendizagem e desatenção. Dos resultados das avaliações, 43,8% foram de dificuldades escolares de ordem pedagógica e 32,2% de deficiência intelectual.

O objetivo da presente pesquisa foi avaliar o repertório de estratégias de aprendizagem utilizadas por estudantes do ensino fundamental I e relacioná-lo com o desempenho em leitura, escrita e aritmética. Participaram do estudo 50 estudantes sem queixas de dificuldades de aprendizagem, de ambos os gêneros, 8 anos, cursando o 2o ano de duas escolas públicas, avaliados por meio da "Escala de avaliação das estratégias de aprendizagem para o ensino fundamental" (EAVAP-EF) e pelo "Teste de Desempenho Escolar" (TDE). As avaliações ocorreram individualmente no contexto escolar. Os resultados mostraram correlações estatisticamente significativas e positivas entre o desempenho em escrita, aritmética, leitura e total (TDE) e os escores de ausência de estratégias metacognitivas disfuncionais, estratégias cognitivas, estratégias metacognitivas e total (EAVAP-EF). A análise de regressão indicou que os diferentes escores da EAVAP-EF foram capazes de predizer o desempenho no TDE, principalmente em aritmética, leitura e total. O estudo permitiu identificar as relações e o valor preditivo das estratégias de aprendizagem para o desempenho escolar.
This research aimed to evaluate the repertoire of learning strategies used by students of the elementary school and its relationship with performance in reading, writing and arithmetic. Participated fifty students without complaints of learning difficulties, both genders, 8 years old, attending the 2nd year of two public schools, evaluated by the "Learning strategies scale for basic education" (EAVAP-EF) and the "School Performance Test" (TDE). The evaluations were performed individually in the school context. The results showed statistically significant and positive correlations between performance in writing, arithmetic, reading and total (TDE), and the scores of absence of dysfunctional metacognitive strategies, cognitive strategies, metacognitive strategies and total (EAVAP-EF). The regression analysis indicated that different scores of the EAVAP-EF were able to predict performance in TDE, especially in arithmetic, reading and total. The study identified the relationships and the predictive value of learning strategies for school performance.

O objetivo da presente pesquisa foi investigar as relações entre as funções executivas (FEs) e o desempenho em fluência e compreensão de leitura de escolares com dificuldades de aprendizagem. Participaram do estudo 29 estudantes, sendo 20 meninos e 9 meninas, cursando do 3º ao 9º ano do Ensino Fundamental, idade média de 11,79 (DP = 2,23), selecionados entre os pacientes que passaram por avaliação neuropsicológica no Ambulatório de Neuro-Dificuldades de Aprendizagem do Hospital de Clinicas (UNICAMP) e no Centro de Investigação da Atenção e Aprendizagem (CIAPRE). Foram utilizados os instrumentos: indice de memória operacional, subteste de digitos (ordem indireta), subteste sequência números e letras, cubos de corsi, teste das trilhas, teste cor-palavra de Stroop, teste de fluência verbal, torre de Londres, texto "A coisa" e teste de Cloze. Os dados foram analisados por meio do SPSS 21.0. Os resultados demonstraram correlações significativas entre os escores dos instrumentos variando de moderada a alta. As maiores correlações do desempenho em compreensão de leitura ocorreram com o controle inibitório, a memória operacional e a fluência verbal. É possível inferir que as FEs contribuem com os aspectos estratégicos e metacognitivos da leitura, sendo que estudos posteriores podem investigar o valor preditivo das FEs para a compreensão.
The aim of this research was to investigate the relationship between the executive functions (EFs) and performance in fluency and reading comprehension of students with learning difficulties. Participated twenty-nine students, 20 boys and 9 girls, attending the 3rd to 9th grade of elementary school, average age of 11,79 (SD=2,23), selected among patients who underwent neuropsychological assessment in Learning Disabilities Outpatient Clinic (Hospital de Clínicas - UNICAMP) and Center for Research on Attention and Learning (CIAPRE). The instruments used were: working memory index, digit span (indirect order), letter-number sequencing, Corsi block-tapping task, trail making test, Stroop color-word test, verbal fluency test, Tower of London, text "A coisa" and Cloze test. Data were analyzed by SPSS 21.0. The results showed significant correlations between the scores of instruments ranging from moderate to high. The highest performance in reading comprehension correlations occurred with inhibitory control, working memory and verbal fluency. It is possible to infer that the EFs contribute to the strategic and metacognitive reading, and further studies may investigate the predictive value of EFs for comprehension.
ABSTRACT
Abstract This paper aimed to verify evidences of validity and reliability of Luria-Nebraska Test for Children (TLN-C, in Portuguese). Three hundred eighty-seven students aged 613 years old, with learning difficulties, comprised the study. They were assessed with the Wechsler Intelligence Scale for Children (WISC-III) and TLN-C; and effect of age differences, as well as accuracy rating by internal consistency were investigated. Age effects were found for all subtests and in the general score, except for receptive speech subtest, even when total IQ effect was controlled. Reliability analysis had satisfactory results (0.79). The TLN-C showed evidences of validity and reliability. Receptive speech subtest requires revision. (AU)
