Abstract: This study has the purpose of analyzing the possible factors that early sport practice can develop on children especially without pedagogical and scientific based. The lack of a specific subject concentrated on child development studies in most physical education courses in Parana l according to Sports and Tourism Secretary. Presents different degrees of competency levels in the field. The more meaningful the Physical Education teaching is the greater the respect to the principles of age, growth, maturation and development. It is necessary to improve sport skills, and to respect children's individual differences. The child learns when he/she is ready to learn, and excessive emphasis on winning should be avoided before the age of twelve, especially for injuries prevention. The awareness of child development changes and the modification of the curriculum in the Physical Education Schools are suggested. Physical activities for children should be meaningful, according to children age level and motivation, stimulating an active and healthy freestyle. Este estudo tem o objetivo de analisar os possíveis fatores que a prática desportiva precoce pode desenvolver nas crian as, especialmente sem base pedagógica e científica. A falta de um assunto específico concentrou-se em estudos do desenvolvimento infantil na maioria dos cursos de educa o física no Estado do Paraná. l de acordo com a Secretaria de Turismo e Desporto. Apresenta diferentes graus de níveis de competência no campo.

Abstract: A hypokinetic lifestyle has increased among children and adolescents in the past few years, leading to risk factors which favor the chronic-degenerative diseases in the early childhood. Thus, the development of physical activity programs for this age group becomes necessary. The purpose of this study was to review the literature about the factors that can be related to the development of weight training programs with extra load for children. Aspects related to the physical activity in the childhood, caloric damage, physical fitness related to health, reasons that make children and adolescents practise or give up physical activity, physical fitness stability during childhood, physiological aspects and growth factors, are discussed. The factors that can interfere in the motor capacity strength, the myths related to weight training with children, possible benefits obtained from this practice, factors that should be taken into consideration regarding specific weight training for children, weight training supervision during childhood, general guidelines for weight training in children, developing weight training programs for children and discussion about strength testing, are dealt with more specifically. When supervised properly by specialists, the specific and individualized training for children and adolescents can generate a significant muscular strength gain, and contribute favorably for health promotion and life quality in this age group. Um estilo de vida hipocinético tem aumentado entre crian as e adolescentes nos últimos anos, e isso faz com que os fatores de risco se apresentem mais facilmente, favorecendo o surgimento de doen as cr nico-degenerativas já na infancia. Logo, torna-se necessário a cria o de programas de atividade física para essa faixa etária. O objetivo desse estudo é realizar uma revis o de literatura acerca dos fatores que se relacionam à montagem de um programa de treinamento com sobrecarga para crian as. Discutemse aspectos relacionados à atividade física na infancia, gasto calórico, aptid o física relacionada à saúde, motivos que levam as crian as à praticar, ou desistir da atividade física, estabilidade da aptid o física na infancia, aspectos fisiológicos e fatores de crescimento. Mais específicamente, s o tratados os fatores que interferem na capacidade motora for a, os mitos relacionados ao treinamento de for a muscular em crian as, possíveis benefícios advindos dessa prática, fatores que devem ser levados em considera o no treinamento de for a específico para crian as, supervis o do treinamento de for a muscular em crian

Abstract: 1 maximum repetition (1mr) tests have been used in research on strength training effects in children and adolescents. however, little is known about the association between 1mr tests and morphologic, neuromotor and biological maturation variables. therefore, the purpose of the present study was to analyze the relationship between 1mr tests and body composition, anthropometric variables, neuromotor tests and biological maturation. for such purpose, correlational methodology was used. the study involved 10 boys with average age of 10.28 (±2.20) years old. the variables analyzed were: body mass, stature, circumferences, skinfolds and biological maturation (pubic and axillary hair and genital development). hence the sample was submitted to a battery of five neuromotor tests and six 1mr tests sessions for upper (ul) and lower (ll) limbs. data analysis was developed using the shapiro-wilk's test (p<0.05), descriptive statistics and the spearman correlation coefficient (p < 0.01; p< 0.05). a strong correlation between age and the 1mr load for ul and moderate for ll was found. stature presented a moderate correlation with 1mr of ul and strong correlation for 1mr of ll; absolute lean body mass presented moderate and strong correlation for ul and ll, respectively. the 1mr test for ul presented moderate correlation for pubic hair and strong correlation for axillary hair. these results indicated a multifactorial influence in the 1mr test loads demonstrating the importance in the use of morphological aspects, biological maturation and/or chronological age in the results analysis. considering the weak relationship between the neuromotor and the 1mr tests, although they have been well used in research related to strength training on children and adolescents, their results should be carefully used when the purpose is to get information on the magnitude effects of strength training in that age range.

The study sample comprised 29 boys (mean age 8.58±0.63 years, height 1.27±0.07 m, weight 28.94±6.03 kg) and 29 girls (mean age 8.60±0.92 years, height 1.31±0.09 m, weight 31.30±8.56 kg). Participants were allocated into four groups: male control group (MCG, n=15); male intervention group (MIG, n=14); female control group (FCG, n=15); and female intervention group (FIG, n=14). The FIG and MIG took part in a 16-week intervention program that consisted of six stretching exercises performed during the warm-up period of physical education classes. Flexibility was assessed by the sit-and-reach test, which was performed at baseline and after 16 weeks of the intervention program. Factorial ANOVA for repeated measures was used with group, sex, and point in time (pre- or post-intervention) as the independent variables, followed by Tukey’s post-hoc test. Sit-and-reach test performance improved significantly in both intervention groups (MIG, 24.89±5.01 cm at baseline vs. 29.07±4.51 cm post-intervention; FIG, 27.25±4.43 cm at baseline vs. 32.14±3.24 cm post-intervention; P<0.0001). There were no significant changes in either control group (MCG, 24.17±5.14 cm at baseline vs. 23,87±4,35 cm post-intervention; FCG, 28,60±6,07 cm at baseline vs. 28,97±6,38 cm post-intervention; P>0.05). Furthermore, the results revealed a significant group, time interaction (F=1.54, p<0.0001). The performance of stretching exercises during warm-up can increase flexibility in children.

Abstract: The purpose of this study was to analyze the relationship between different body fat indicators, habitual physical activity and exposure to sedentary behavior in pre-adolescent males. The sample involved 60 subjects from 10 to 14 years old. The used body fat indicators were: the Body Mass Index, waist circumference, the sum of eight skinfolds, and estimation of percent of body fat using bioelectric impedance. The indicators of physical activity and sedentary behavior were assessed through a questionnaire. Descriptive statistical procedures were: mean, medium, standard deviations, minimum and maximum values, as well as the Spearman correlation. The SPSS software was used and P values lower than 5% were considered statistically signifi cant. None of the body fat indicators presented signifi cant correlation (p> 0.05) with indicators of habitual physical activity, although, all of them were moderately associated with time spent in sedentary activities (Body Mass Index: r= 0.42, waist circumference: r= 0.43, sum of skinfolds: r= 0.43 and percent of body fat: r= 0.43). Therefore, it is concluded that exposure to sedentary behavior correlates with body composition in pre-adolescent males aged 10 to 14 years. RESUMOO objetivo deste estudo foi analisar a rela o entre diferentes indicadores de adiposidade corporal, atividade física habitual e exposi o a comportamentos sedentários em jovens do sexo masculino. A amostra foi composta por 60 indivíduos com idade compreendida entre 10 e 14 anos. Foram utilizados como indicadores de adiposidade corporal: o índice de Massa Corporal, circunferência de cintura, somatória de oito dobras cutaneas e estimativas do percentual de gordura corporal, calculada por meio de impedancia bioelétrica. Os indicadores de prática de atividade física e comportamentos sedentários foram avaliados através da aplica o de questionário. Os procedimentos estatísticos adotados foram: valores de média, mediana, desvio padr o, valores mínimos, máximos e correla o de Spearman. O software utilizado foi o SPSS e valores de P inferiores a 5% foram considerados estatisticamente signifi cantes. Nenhum dos indicadores de adiposidade corporal apresentou correla o signifi cante (p> 0,05) com os indicadores de prática de atividade física, no entanto, todos foram moderadamente associados (índice de Massa Corporal: r= 0,42; circunferência de cintura: r= 0,43; somatória de dobras cutaneas: r= 0,43 e gordura percentual corporal: r= 0,43) com o tempo despendido em atividades sedentárias. Desta forma, conclui-se que a exposi o a comportamentos sedentários ap

Abstract: The objective of this study was to describe the prevalence of overweight and obesity among schoolchildren attending private schools in the town of Presidente Prudente, SP, Brazil. The sample comprised 1,215 male and female students with an age range of 10 to 17 years. Body mass and height measurements were evaluated. Nutritional status was identifi ed by means of Body Mass Index and the international table of reference values proposed by Cole et al.12 Data are represented in the form of means, standard deviations and frequencies. The Chi-square test was used to compare frequencies and Student’s t test was applied to and means. P values below 5% were considered statistically significant and all statistical analysis were performed using SPSS 10.0 dedicated software. The observed prevalence rate of overweight and obesity was 35.7% for males, 20% for females (p = 0.001) and 28.6% for the whole sample. Therefore, this study concludes that the high overweight and obesity rates observed among students from the town of Presidente Prudente, particularly among the male sex, should be seen as a warning and indicate the need for interventions by health professional in the school environment. RESUMO O objetivo do estudo foi descrever a prevalência de sobrepeso e obesidade entre escolares da rede privada de ensino do município de Presidente Prudente - SP. A amostra foi composta por 1215 jovens de ambos os sexos e idade entre 10 e 17 anos. Foram coletados valores referentes à massa corporal e estatura. Para indica o do estado nutricional, foi calculado o índice de Massa Corporal e utilizada a tabela internacional de referência proposta por Cole et al.12. Os dados s o apresentados em valores de média, desvio padr o e freqüência. Foram utilizados os testes Qui-quadrado e “t” de Student para compara o entre freqüências e médias, respectivamente. Valores de p inferiores a 5% foram considerados estatisticamente signifi cantes e todo o tratamento estatístico foi realizado no software específico SPSS 10.0. Verificou-se que a prevalência de sobrepeso e obesidade foi de 35,7% para o sexo masculino, 20% para o feminino e 28,6% para a amostra total, sendo a prevalência no sexo masculino superior a observada no feminino (p = 0,001). Assim, conclui-se que os altos valores de sobrepeso e obesidade observados entre os escolares de Presidente Prudente, principalmente entre os indivíduos do sexo masculino, servem como forma de alerta e indicam a necessidade de interven o por parte de profi ssionais da área da saúde em meio escolar.

Abstract: Os objetivos do presente estudo foram: 1) verificar a rela o dos saltos vertical, horizontal e sêxtuplo com a agilidade e velocidade de 5, 10 e 25 m; 2) verificar a capacidade desses saltos em predizer o desempenho da agilidade e velocidade de 5, 10 e 25 m em crian as. Vinte e oito meninos (9,47 ± 0,64 anos) e 30 meninas (9,69 ± 0,70 anos) foram avaliados. Os valores de correla o entre a agilidade, velocidade de 5, 10 e 25 m foram, respectivamente, r = 0,63, 0,51, 0,44 e 0,64 com o salto vertical, r = 0,68, 0,62, 0,28 e 0,62 com o salto sêxtuplo, e r = 0,60, 0,50, 0,26 e 0,57 com o salto horizontal. O salto vertical e o salto sêxtuplo foram capazes de predizer o desempenho da agilidade e da velocidade de 25 m (p < 0,05). Além disso, demonstraram capacidade de predizer a velocidade de 5 e 10 m, respectivamente (p < 0,05). Os testes de salto vertical e sêxtuplo podem ser utilizados para avalia o e controle do treinamento com crian as praticantes de atividades que demandam agilidade e velocidade, uma vez que ambos os saltos predisseram o desempenho da agilidade e velocidade, o que n o ocorreu com o salto horizontal. The aim of the present study were: 1) To verify the relationship of vertical, horizontal and sextuple jumps with agility and velocity of 5, 10 and 25 m; 2) To verify the capacity of these jumps to predict the agility and 5, 10 and 25 m velocity performance in children. Twenty eight boys (9.47 ± 0.64 years) and thirty girls (9.69 ± 0.70 years) were evaluated. The correlation values between agility and velocity on 5, 10 and 25 m velocity were, respectively, r = 0.63, 0.51, 0.44 and 0.64 with vertical jump, r = 0.68, 0.62, 0.28 and 0.62 with sextuple jump, and r = 0.60, 0.50, 0.26 and 0.57 with horizontal jump. The vertical and sextuple jumps were able to predict the agility and 25 m velocity performance (p < 0.05). Furthermore, they demonstrated capacity to predict 5 and 10 m velocity, respectively (p < 0.05). The vertical and sextuple jump tests may be used for assessment and control of training with children practicing activities that require agility and velocity, since both jumps predicted the agility and velocity performance, which did not occur with the horizontal jump.

Journal of Human Sport and Exercise , 2012,
Abstract: Although dynamic and stretching exercises have been widely investigated, there is little information about warm up performed by tag games. Thus, the purpose of the present study was to verify the acute effect of dynamic exercises compared to a tag game warm up on agility and vertical jump in children. 25 boys and 24 girls participated in this study and performed the agility and vertical jump tests after warm up based on dynamic exercises or as a tag game lasting 10 min each in two different days randomly. Dynamic exercises warm up consisted in a run lasting 2.5 min followed by 2 series of 8 dynamic exercises lasting 10 seconds each interspersed with 20s of light run to recovery. Tag game warm up was performed by a tag game with two variations lasting 5 min each. The first variation there was a single cather, which aimed to get the other participants by touching hands. In the second part of the game, the rules were the same except that the participant that was caught had to help the catcher forming a team of catchers. Warm up intensity was monitored by OMNI perceived exertion scale. ANOVA 2x2 for repeated measures (Warm up x Sex) demonstrated no significant differences between dynamic exercises and tag game for agility and vertical jump (P>0.05) for boys and girls. Perceived exertion was significantly higher in tag game compared to dynamic exercises on girls (P<0.05). Both warm up models showed similar acute effects on agility and vertical jump in children.
