“…The relationship between PA and motor performance corroborates the findings of most studies that report a positive association between PA and muscular strength and endurance as well as overall physical fitness, particularly in the standing broad jump (Lennox et al, 2008; Loko et al 2003; Wrotniak et al, 2006), medicine ball throw (Loko et al, 2003), push-ups (Lennox et al, 2008, Tovar et al, 2008) and isometric hand-dynamometry (Tovar et al, 2008). Different results were obtained by Hands et al (2009), who found no significant associations between PA and performance in standing broad jump, curl-ups, hand dynamometry and ball throw.…”

The purpose of this study was to analyse the interaction between somatotype, body fat and physical activity in prepubescent children. This was a cross-sectional study design involving 312 children (160 girls, 152 boys) aged between 10 and 11.5 years old (10.8 ± 0.4 years old). Evaluation of body composition was done determining body mass index and body fat by means of skin-fold measurements, using the method described by Slaughter. Somatotype was computed according to the Carter’s method. Physical activity was assessed with the Baecke questionnaire. The physical activity assessment employed sets of curl-ups, push-ups, standing broad jump, medicine ball throw, handgrip strength and Margaria-Kalamen power stair. There were negative associations for body fat, endomorphy and mesomorphy with curl-ups, push-ups and broad jump tests and positive associations with ball throw, handgrip strength and Margaria-Kalamen power tests. The associations for ectomorphy were the inverse of those for endomorphy and mesomorphy. Non obese children presented higher values for curl-ups, push-ups and standing broad jump. In medicine ball throw, handgrip strength and Margaria-Kalamen power test obese children presented higher scores, followed by children who were overweight. The mesoectomorphic boys and ectomesomorphic girls performed higher in all tests. The morphological typology presented more interactions with strength than % of body fat and physical activity. These data seem to suggest that the presence/absence of certain physical characteristics is crucial in the levels of motor provision in prepubescent children.

“…Functional power was evaluated by standing long jump, whereby each child jumped horizontally forward as far as possible by taking off and landing with both feet. 29 The distance from the start line to the heel of the closest foot was recorded in centimeters (cm). Three trials were recorded and averaged for analysis.…”

Evolution of foot and ankle manifestations in children with CMT1A

2009

We studied the timing and progression of foot and ankle changes in 81 children with genetically confirmed Charcot-Marie-Tooth disease type 1A (CMT1A) and determined their impact on motor function and walking ability. Foot deformity, weakness, pain, cramps, and instability were a common feature of CMT1A. Foot structure evolved toward pes cavus from early childhood to adolescence, although a subgroup with normal and planus feet remained. Foot strength increased with age, although compared to age-equivalent norms it declined from 4 years. Factors associated with evolving foot deformity included muscle weakness/imbalance, restricted ankle flexibility, and joint hypermobility. Regression modeling identified dorsiflexion weakness, global foot weakness, and difficulty toe-walking as independent predictors of motor dysfunction, while pes cavus and difficulty heel-walking were predictors of poor walking ability. Foot problems are present from the earliest stages of the disease and can have a negative impact on function. Early foot and ankle intervention may prevent long-term disability and morbidity in CMT1A.

“…São vários os estudos existentes na literatura que referem associações significativas e positivas do tempo despendido na atividade física com a prestação em habilidades motoras fundamentais, nomeadamente no lançamento da bola (Fisher et al, 2005;Loko, Aule, Sikkut, Ereline, & Viru, 2003). Pelo contrário, não foram observadas associações da prática desportiva dos familiares com a prestação do lançamento.…”

ARTIGO ORIGINAL | ORIGINAL ARTICLE RESUMOO objetivo deste estudo foi analisar o efeito de fatores de ordem biológica, sociocultural e motora na prestação da habilidade motora fundamental lançamento, em crianças de 10 e 11 anos de idade. Tratou-se de um estudo transversal envolvendo 96 crianças, 49 rapazes e 47 raparigas (idade decimal, 10.94 ± 0.52). Foi avaliado o produto (distância) e processo (padrão motor) do lançamento. A comparação entre grupos no que respeita à distância do lançamento foi realizada com o t-teste enquanto no que se refere ao padrão de lançamento envolveu os testes de U Mann-Whitney e Kruskal-Wallis Recorreu-se à correlação de Pearson para analisar as associações entre as variáveis experimentais. A análise do efeito dos fatores na prestação da habilidade de lançamento envolveu o Modelo Geral Linear. As crianças situadas no estádio maduro de todos os componentes do lançamento tiveram o melhor desempenho (p<0.001). Verificou-se um efeito de elevada dimensão do número de assoalhadas da habitação (p 2 = 0.995; p= 0.043), tempo despendido com jogos eletrónicos ao sábado (p 2 = 0.995; p= 0.044), estatura (p 2 = 0.995; p= 0.045) e sexo do companheiro de brincadeira (p 2 = 0.996; p= 0.040) na prestação do lançamento. Conclui-se que em idades pré-pubertárias, para além das variáveis de natureza biológica, as variáveis socioculturais parecem desempenhar um papel fundamental na prestação da habilidade manipulativa lançamento.Palavras-chave: lançar, pré-puberdade, produto, processo ABSTRACT The aim of this study was to analyse the effect of the biological, sociocultural and motor variables in the performance of the fundamental motor skill throwing in children aged between 10-11 years old. This was a cross sectional study involving 96 children, 49 boys and 47 girls (10.94 ± 0.52 years). It was evaluated the product (distance) and process (motor pattern) of throwing. To analyse the differences between groups in the throwing distance an analysis of variance (ANOVA) and a t-test were used. To analyse the differences between groups in terms of the distance of throw we used t-test while U de Mann-Whitney and KruskalWallis tests were used to depict differences in the patterns of throw. The Pearson correlation was used to analyse the associations between experimental variables. The evaluation of the effects of the factors on the performance of throw was performed using the General Linear Model. The children situated at the mature stage of all the throwing components had the best performance (p< 0.001). There was a high-sized effect of the number of rooms of the house (p 2 = 0.995; p= 0.043), time spent playing electronic games on Saturday (p 2 = 0.995; p= 0.044), height (p 2 = 0.995; p= 0.045), and sex of the friend whom the child plays with (p 2 = 0.996; p= 0.040) on the throwing performance. We can conclude that beside a biological influence, the performance of the manipulative skill throwing in pre-pubertal ages appears to be relevantly influenced by socio-cultural variables.
