Morfologia externa, composição corporal e performance motora do praticante de atletismo madeirense : um estudo em atletas dos 11-17 anos de idade

Os objetivos centrais da presente pesquisa foram quatro: (1) recolher informação nos domínios do crescimento físico humano, composição corporal, tipo físico, aptidão física e prática desportiva do atleta infanto-juvenil praticante de atletismo; (2) estudar a variação associada à idade e ao sexo; (3) investigar as diferenças entre atletas e não-atletas; e (4) identificar os preditores da capacidade funcional. A amostra foi constituída por 105 praticantes de atletismo, 49 do sexo masculino e 56 do sexo feminino, com idades compreendidas entre os 11 e os 17 anos, de cinco clubes da Região Autónoma da Madeira. As variáveis de estudo incluíram a altura, o peso corporal, os diâmetros ósseos, os perímetros musculares, as pregas de adiposidade subcutânea, a massa isenta de gordura (MIG), a massa gorda, o tipo físico, os testes motores, e os anos e as horas de treino semanal. Os ‘scores’ Z, os testes t-student e Mann-Whitney U, a ANOVA e a regressão linear múltipla foram os procedimentos estatísticos utilizados nas análises. O atleta do sexo masculino foi mais alto, pesado, robusto e apresentou mais MIG do que o sexo feminino (p<0,05). Os atletas apresentaram um físico mesomorfo equilibrado (sexo masculino) e meso-endomorfo (sexo feminino). Os rapazes apresentaram valores significativamente superiores na aptidão física geral e específica, comparativamente às raparigas. As raparigas apresentaram melhores desempenhos no ‘sit and reach’(p<0,05). Os valores médios para a altura, peso corporal, testes motores e características da prática desportiva foram superiores nas atletas mais velhas (p<0,05). Os praticantes de atletismo apresentaram menos gordura subcutânea e melhores desempenhos no salto em comprimento sem corrida preparatória e corrida de 12 minutos, do que as não-atletas. A altura, a percentagem de gordura, os anos de prática desportiva e o número de horas de treino por semana foram os preditores que mais contribuíram para explicar a variância nos testes motores.Os resultados demonstraram um dimorfismo entre atletas do sexo masculino e feminino. O treino estava associado a melhores desempenhos nos testes motores e a valores mais baixos de gordura corporal. A altura, a gordura corporal e as características da prática desportiva foram importantes na predição da capacidade funcional.

É a luta da gente! : juventude e etnicidade na comunidade Quilombola de capoeiras (RN)

On this paper, I propose a reflexion on the formation of a youth maroon, as a political subject , based on experience, personal expectations and social projects in the construction of a political identity in the community quilombola Capoeiras, which is located in the district of Macaíba (RN). I observed two social situations; the projects of the Pau-furado Youth and the Swingueira Quilombola , those kinds of dances that have as protagonists or as audience the youth people who lives in the community here mentioned, those people that legitimize and innovate in these traditions and roles they play and crucial positions in the construction of ethnic identities and generation within a political community. It seeks to understand the place of youth in this new context of political affirmation and identity. It is, therefore, to understand the diversity in their local youth from different social, cultural, political and economic

Arte, prazer e bisturi: construção corporal através da body modification

In view of a field research carried out by a team connected to the universe of body modification, it is possible to discern some uses and meanings linked to these forms of body interventions. Body modification or body change is part of the circuit of piercings and tattoos, although they are socially less thinned and more extreme, like scarifications, subcutaneous implants, bifurcated tongues, surfaces and body suspensions. The aim of this paper is to cast an anthropological glance on these practices, joining at the same context all the subjects involved with these techniques, placing them inside the same relational focus and capturing their journeys and trajectories. The discussions are concentrated on the notion of body building and urban life style. Ideas as personal distinctness and prestige imitation are also present in this universe, as well as matters attached to genre, pleasure, art, and to the so-called alternative circuit . This way, the ethnography so far presented here, reveals the complex and contemporaneous character of these practices of body markings in which the body appears as the central element in the experiences of the subjects of this study

Comparação antropométrica, composição corporal, somatotipo e saltos verticais de atletas de voleibol de praia masculino

The kinanthropometric characteristics are used by the sports science as selection criteria and detection of talents. Hence, this study aimed at comparing the anthropometrical profile, the body composition, the somatotype and the vertical jumps of the beach volleyball players. This study consists of 79 male beach volleyball players, being forty nine (n=49) Brazilian participants of the National Circuit and thirty (n=30) of 15 countries participating in the XV Pan American Games. In order to analyze the vertical jumps of the Brazilian the participants were allocated into two groups (G1 and G2) in agreement with the national ranking of their teams. The vertical jump protocol developed by Smith and collaborators was used to evaluate the vertical jumps of spike and block. The Heath-Carter anthropometrical technique (1990) was used for calculating the somatotype. The Student s t test with the Bonferroni adjustment was used to calculate the differences among the investigated variables. The multiple regression analysis was used to identify the contributions of the anthropometrical variables in the performance of the vertical jumps and the multivariance analysis was used to calculate the differences among the components of the somatotype. The Brazilian athletes of G1 were better than G2 in the spike jump (p <0.01), block jump (p <0.01) and in the block difference (p <0.01). The prediction model of the spike jump of G2 included the body mass and standing spike reach (adjusted R2 = 0.77), the body mass and the standing block reach were also included in the model of the block jump (adjusted R2 = 0.73). The regression model of G1 was not statistically significant. As for the somatotype, statistically significant differences were found between the Brazilians and the Pan Americans (Wilks' lambda = 0.498; p <0.05). The Brazilian somatotype was classified as balanced mesomorph (2.7-4.3-3.0) and the Pan American somatotype as endomorphic mesomorph (3.5-4.6-2.4). As to the specific position of the block game (2.8-4.3-2.9) and the defense game (2.6-4.4-3.0), the Brazilian somatotype was classified as balanced mesomorph and the Pan American somatotype, the block (3.7-4.4-2.4) and the defense (3.4-4.9-2.3), was classified as endomorphic mesomorph. In conclusion, the vertical jump height (spike and block) influences the male Brazilian beach volleyball players performance. The physical type of the Brazilian blockers and defenders was similar with relationship to the somatotype. The Brazilian and Pan American beach volleyball players differ in terms of kinanthropometric characteristics. This work had a multidisciplinary feature with the participation of several departments and laboratories, like the Physiotherapy Department, the Nutrition Department, the Physical Education Laboratory, thus corroborating the multidisciplinary research feature

Imagem corporal e fatores de risco em praticantes de caminhada da cidade do Natal-RN

Body image is the figure of our bodies built in our minds and the degree of dissatisfaction is often associated with risk factors identified by anthropometric measures. The purpose of this descriptive study was to evaluate the risk factors associated to morphological and functional variables associate to the perception of auto-image in middle-aged walkers of the south zone of the city of Natal. A hundred and thirty volunteers had been evaluated in four groups in function of the gender and age group. As measurement evaluations were used an auto-image perception questionnaire proposed by Stunkart of nine silhouettes numbered for both gender was applied; a weighing machine equipped with stadiometer for the body mass (kg) and stature (m) and the body mass index (kg/m2) that was calculated with base in measures of the body weight and stature and classified according to norms of the National Institute of Health (2000) as well as the systolic and diastolic blood pressure by a electronic digital device (DIGITRONIC). A metal anthropometric tape was used for the waist to hip ratio (WHR). It was used Analyses of variance (ANOVA) one-way, post hoc of Tukey and correlation of Spearman for the nonparametric data adopting the level of ρ≤ 0,05 for rejection of the null hypothesis. The body mass index indicated high factors of risk in the consisting groups. In all the groups were registered the desire to reduce their silhouettes. The body weight shows reduced when compared with the younger group in the male group of superior age group, while in the female group the inverse one occurs. The autoimage perception is associated with the classification of the waist to hip ratio in the female gender in the age group of the 50 to the 59 years and in the classification of the body mass index of all constituted groups. Significant associations had not been found for classification of the systolic and diastolic blood pressure in relation to the auto-image 41 perception. This thesis presents relation of interdisciplinarity and its contents have application in the fields of Physical Education, Medicine, Physiotherapy and Nursing

Estado nutricional antropométrico, composição corporal e pressão arterial em adolescentes

Os objetivos deste trabalho foram: (1) estimar as prevalências de excesso de peso e de gordura corporal, obesidade central e pressão arterial elevada (PAE) em adolescentes beneficiários do Programa Nacional de Alimentação Escolar (PNAE) da rede municipal de ensino de Natal-RN; (2) verificar a associação entre variáveis antropométricas e de composição corporal com a pressão arterial, a maturação sexual e a história familiar positiva de fatores de risco para doença cardiovascular (FRDCV); (3) comparar dois padrões de referência para classificação do excesso de peso em adolescentes; e (4) propor equações preditivas de massa gorda (MG) e massa livre de gordura (MLG) baseadas nos perímetros corporais. Trata-se de um estudo transversal, com 526 adolescentes beneficiários do PNAE, em Natal, Brasil. O tamanho da população de estudo foi definido por amostragem aleatória, em dois estágios, e ponderada segundo número de alunos de cada escola. No primeiro estudo, o excesso de peso foi determinado por Índice de Massa Corporal (IMC), a gordura corporal estimada por dobras cutâneas e a obesidade central por perímetro abdominal. A pressão arterial elevada foi classificada conforme a American Academy of Pediatrics. As prevalências foram apresentadas em valores relativos e efeito do desenho. Realizou-se uma análise fatorial para sintetizar o conjunto de variáveis antropométricas visando identificar fatores comuns. Extraíram-se dois fatores: (1) padrão excesso de adiposidade e (2) padrão adiposidade central elevada. Para avaliar a associação entre os padrões de adiposidade corporal com pressão arterial elevada, faixa etária, maturação sexual e história familiar de FRDCV utilizou-se a Razão de Chances e respectivo intervalo de confiança de 95% e regressão logística. No segundo estudo, calculou-se a sensibilidade e a especificidade do excesso de peso classificado segundo o IOTF e a World Health Organization WHO em relação ao excesso de adiposidade corporal; e a estatística Kappa para medir a concordância entre os dois padrões de referência. No terceiro estudo, foram elaborados modelos preditivos de MG e MLG com base em nove perímetros corporais, utilizando a bioimpedância Byodinamics 450 como padrão de referência. Para tanto foram selecionados 218 adolescentes eutróficos, segundo o IMC a partir do estudo transversal. As equações foram estimadas por regressão linear múltipla, considerando a idade e os perímetros corporais. Os resultados apontaram que 14,1% dos meninos e 15,7% das meninas tinham excesso de peso; 15,3% dos meninos e 11,6% das meninas tinham excesso de gordura corporal e dentre os meninos 14,3% tinham pressão arterial elevada e as meninas, 21,4%. Todos os efeitos do desenho foram inferiores a 2,5%. Nos meninos, o padrão excesso de adiposidade foi associado à história familiar positiva de FRDCV (ORajust=2,60; 1,09-6,22), maturação sexual (ORajust=2,92; 1,04-8,22) e PAE (ORajust=3,66; 1,34-9,94). Os meninos com 12 anos e mais apresentaram 6,1 vezes mais chance de apresentar padrão adiposidade central elevada do que os adolescentes com 10 a 11 anos (IC95% 2,32-16,04), assim como os púberes apresentaram 3,2 vezes este mesmo padrão em relação aos pré-púberes (IC95%1,14-8,85). A partir da comparação entre os dois padrões de referencia de classificação do excesso de peso por meio do IMC, observou-se que a sensibilidade foi de 79,3% para o critério IOTF e de 88,9% para WHO e a especificidade foi de 94,7% e 89,9%, respectivamente. O nível de concordância foi maior para o critério IOTF (Kappa=0,70 x Kappa=0,64). Em relação à construção das equações preditivas de gordura corporal, do total de 106 meninos e 112 meninas, foram desenvolvidas duas equações para estimar MG e duas para MLG, considerando o sexo. No sexo masculino, a equação para estimar a MG incluiu as variáveis idade, punho, quadril e perímetro abdominal (R2=0,552; AIC=416,04) e MLG, idade, punho e antebraço (R2=0,869; AIC=578,24). Enquanto que no feminino, MG foi estimada pelas variáveis punho, perímetro do abdômen, do quadril, da coxa proximal e da panturrilha (R2=0,838; AIC=415,36); e a MLG por idade, punho, perímetro do abdômen, do quadril e da panturrilha (R2=0,878; AIC=512,48). Conclui-se que os adolescentes tinham elevada prevalência de excesso de adiposidade corporal e de pressão arterial elevada. Tanto o padrão excesso de adiposidade quanto adiposidade central elevada constituem-se em padrões de risco. O padrão excesso de adiposidade foi associado à pressão arterial, história familiar positiva de FRDCV e maturação sexual em meninos. O critério IOTF mostrou-se menos sensível, mais específico, com maior nível de concordância e maior probabilidade de identificar corretamente o excesso de gordura corporal nos adolescentes avaliados. Quatro equações foram desenvolvidas para a estimativa da MG e MLG em adolescentes. As equações desenvolvidas para estimar a MG no sexo feminino e MLG para ambos os sexos apresentaram valores elevados de coeficiente de determinação ajustados e, portanto, são as preferenciais. Este estudo foi realizado com a participação de equipe multidisciplinar composta por professores da área de Nutrição, Endocrinologia Pediátrica, Estatística, Educação Física, discentes do Curso de Graduação em Nutrição e residentes em Pediatria

Zinco Sérico e parâmetros farmacocinéticos na determinação do estado corporal de zinco em crianças

O zinco é um micronutriente fundamental para as funções vitais de qualquer organismo vivo e sua deficiência em humanos pode causar alterações na expressão gênica, crescimento e desenvolvimento infantil, e proteção antioxidante. Devido à sua importância, as concentrações corporais de zinco são estritamente controladas por processos homeostáticos complexos. Este controle reflete no fato da deficiência grave de zinco ser detectada apenas após privação crônica. Embora se estime que a deficiência leve seja comum, os métodos existentes para avaliação individual do estado corporal de zinco são limitados e pouco eficazes. O objetivo deste trabalho foi avaliar o zinco sérico basal e os parâmetros farmacocinéticos na determinação do estado corporal de zinco em crianças, estabelecendo relação entre esses índices. O estudo foi aprovado pelo Comitê de Ética em pesquisa do Hospital Universitário Onofre Lopes (CEP-HUOL) e 129 crianças, eutróficas e aparentemente saudáveis, entre 6 e 9 anos de idade, foram avaliadas antes e após a suplementação oral de zinco (5 mg Zn/dia) durante 3 meses. No início e fim do período houve a administração venosa de zinco (0,06537 mg de Zn/kg de peso) em 40 destas crianças para avaliação dos parâmetros farmacocinéticos por meio de três diferentes fórmulas de clearance de zinco. Os limites do CI (95%) para o zinco sérico basal variaram entre 0,94 1,00 e 0,91 0,98 μg/mL em meninas e meninos, respectivamente. Em relação aos parâmetros farmacocinéticos, a fórmula específica para um compartimento apresentou correlação positiva com o zinco sérico após a suplementação e foi efetiva em detectar mudanças no estado corporal de zinco

Farelo de canola em dietas para o pacu Piaractus mesopotamicus (Holmberg 1987): efeitos sobre o crescimento e a composição corporal

Avaliaram-se os efeitos da inclusão de farelo de canola em dietas de juvenis de pacu (Piaractus mesopotamicus) sobre parâmetros de crescimento e composição corporal. Um total de 192 alevinos (9 a 15g) foram estocados em 24 tanques de cimento, de 100l de capacidade, durante 103 dias. O farelo de canola foi utilizado em quatro proporções: zero; 9,5%; 19% e 38% da dieta, com ou sem farinha de peixe (12%/dieta), totalizando oito tratamentos. A presença de farinha de peixe não afetou os parâmetros de crescimento avaliados. A inclusão de 38% de farelo de canola na dieta diminuiu o ganho de peso dos peixes, valores médios de 28,74g a 50,70g, e piorou a conversão alimentar aparente, de 1,66 para 2,85. A taxa de eficiência protéica também foi menor nos peixes alimentados com 38% de farelo de canola. As várias proporções de farelo de canola das dietas alteraram os teores de umidade, proteína bruta e lipídios dos peixes. A presença da farinha de peixe, nas dietas, somente influiu no teor de lipídios dos peixes alimentados com dietas contendo 9,5% de farelo de canola. Conclui-se que até 19% de farelo de canola pode ser adicionado às dietas de juvenis de pacu, sem que seu desenvolvimento seja prejudicado.

Tempo livre de lazer e composição corporal de escolares do meio-oeste catarinense

The aim of this study was to investigate the relationship between free time for leisure and body composition of students in the crucial ninth year. (N = 228) of towns in the Midwest catarinense. We used the Adolescent Behavior Questionnaire of Santa Catarina (COMPAC) to assess lifestyle, considering that Active schoolchildren during the week, accumulated 300 or more minutes of moderate or vigorous physical activity (MVPA). Were used the time to 2 hours or more / day to determine the time of excessive use of TV and computer video game. To analyze body composition were used two criteria: the Body Mass Index (BMI) and sum of skinfolds (EDC). It was observed a proportion of 67.3% of girls and 68.7% of boys assets and more than 98% of students were using excessive TV time, computer and video game. In the classification by EDC, most of the boys showed great or low levels of body composition, while more than half of girls were classified at higher levels. As for BMI, most boys and girls had not overweight. Significant difference in the comparison of total minutes per week of MVPA reported between the groups, the second criterion of EDC and BMI for girls but not for BMI in boys. It is concluded that students with higher accumulation in minutes of MVPA showed better body composition indicators, but no significant difference was found when compared active groups with inactive, according to criteria used.

Break: o grito corporal da periferia

In order to question a sociology as it considers appropriate the body dimensions, which contributes in a mean singular in relation to body, not only as a matter, but mainly as a producer of knowledge, our research shows a reflection on corporality as the production of knowledge and to understand different perspectives and social logic here in contemporaneity, whose rationality seems to be placed in question through a performance expressed, a lot of 'breaks', including the space, which the dancer break appropriates of a reversed form and not more than linear. Our problem is the possibility of a greater understanding of this young body with dance the break, is not only 'breaking' his body, but fluent in their own body fragments, producing probably a break in relation to a dominant power established, by creating a kind of 'social resistance' to provide another sense for his life, out of the senses by the dominant of a social field. This is the area of production of knowledge, of the 'body' that cries keep our eyes, the challenge of dive in the depth of gestures, beyond the physical structure, restoring in a strong political constitution and cultural in so far as this body faces. The body as spectacular becomes 'cause and effect' of communication, this body is not only individual, it is not expression only for itself; when the young dance outside their walls individuals, makes it relational, turning to relate with the other, with the space, time and the world. The methodological point of view, to study this corporality in element break, the body as language of senses, we considered withdrawals in the field, observations of movements of the universe of break creative dance, performance and analysis of "attitudes" (expression peculiar world hip hop ), as well as my experience with dancing in the street interventions through 'urban' and our own attitudes to the object of research which challenges us academically and, it all, existentially

Desenvolvimento, pobreza e meio ambiente no seridó potiguar: um estudo centrado nas micro-regiões do seridó oriental e ocidental

This research work intends to carry out a study focused on the dynamic between development, poverty reduction and conservation of natural resources. To consider this relationship to the region chosen was the micro-region of Eastern and Western Seridó in the state of Rio Grande do Norte. In recent years, several studies (Araújo, 2011; BASTOS, 2009) have pointed out that after a period of economic crisis in its tripodproductive, formed by the activities of farming, cotton farming, mining and faced in the eighties, this region of the State of Rio Grande do Norte, has not only shown signs of economic recovery but also improve their social indicators. On the other hand, studies of desertification as the view of the state of RN (produced in cooperation between the Government of RN and research institutions) and the Sustainable Development Plan of Seridó (ADES, 2000), indicate that there is an ongoing French process of degradation of natural resources that is capable of compromising the ability of sustaining such a system. To verify this reality and likely finding this relationship, this work is adopted for this study, the analysis of evolution of secondary data from official bodies such as the IBGE on HDI, per capita income and other social indicators between 2000 and 2009. Here is another time of the survey analysis of qualitative data collected from interviews with institutions of academic intervention in nature, researchers at the Federal University of Rio Grande do Norte (UFRN) State agencies that address the issue of the Middle Environment in Seridó: Institute for Sustainable Development of the NB (IDEMA) and the Brazilian Institute of Environment and the Amazon (IBAMA) and institutions of direct intervention in the region, as the Agency's Sustainable Development Seridó (adhesive) and the Joint Semi-Arid (ASA). After crossing data from quantitative and qualitative, it was found that the dynamics of the region's economic Seridó Potiguar partially answers the improvement of social indicators of poverty. Contribution by the State in this shared stock transfer income. Regarding the influence of productive restructuring in the region on issues of environment, it is noted that the ceramic tile industry, responsible for the absorption percentage of the population with limited ingress into the urban economy, given the low education, accounts for the increase of susceptibility to the ongoing process of desertification in North Seridó Rio Grande. We conclude finally that the guarantee of increased income, freedom and conservation of natural resources ensures primarily by changing the beliefs and values, especially on the part of the business sector, which use natural resources so predatory, aimed at maintaining their rates of return on investment. And concomitantly, the synchronization between technological change, through the use of new energy sources, and institutional change.

"Reforma urbana já"; "arroz, feijão, saúde e habitação" :A luta por moradia na grande João Pessoa

Our object of study in this work concerns to the movement of fight for the housing in the Great João Pessoa, Paraíba, Brazil, and looks for to investigate the conditions and context of the occupations of building, public or private, for devoid populations that do not have where to live. Front to the absence of politics effective directed to the habitation or the cities, in a picture of unemployment and impoverishment of the population, the result of the habitation point of view, is the absolute lack of popular housings, the degradation of the cities and the growth of the number of homeless and also of its occupations. The urban occupations today represent a reply of these devoid populations that from an involvement with parties or Not Governmental Organizations, and social movements leave for the class action known by the occupation of abandoning public or private buildings. These occupations, even so initially if assume as pressure instrument or of visibility for attainment of housings, for the delay in obtaining the attention of the public agencies and a solution for the problem, becomes definitive or is drawn out per many years. E this if gives although the deficiencies, of the accumulation or families neither in an adequate, always precarious space nor in sanitary installations, that the necessary privacy does not allow. The study it consisted of an empirical research, through the participant comment and open and half-open interviews, and counted on the audiovisual register of two occupations, one in the downtown of João Pessoa City (old building of the INSS, in the Ponto dos Cem Réis) and other (Community of the Cajueiro), next to the Beach "Praia do Jacaré", in the city of Cabedelo.The choice of the Visual Anthropology as research instrument is on to a concern in better translating other ways of life, therefore the accomplishment of the video in allows them to know with more precision the reality where the citizens of the research live. We also use as methodological resource in the research the deepened interview, in intention to better understand the description of the way of life of the studied families and the movements of fight for the housing, particularly the MDM - Movement of Right for the Housing, and the MNLM- Nacional Movement of Fight for the Housing

Luta pela terra, luta pela palavra: história de vida e formação de duas educadoras populares do campo

This project has resulted from a reunion between me and two teachers with whom I had already worked, pedagogically counseling them during the execution of the Project of Youngsters and Adults Schooling at the Agrarian Reform Settlements in the State of Sergipe (PAJA/PRONERA) between 2002 and 2003. The matter that really motivated the research was related to the essential principle that guided the accomplishment of the PAJA s teachers education and professionalization: understanding their reality and knowing their needs, promoting the dialogue between scientific and common sense knowledge. Taking as a reference the fact that the teachers education is not restricted to the academic qualification, that is, that it is a part of the educational process, which, in turn, is a result of each one s personal background, dialectically individual and collective, the access to the teachers reality and needs was accomplished by studying their backgrounds, especially their school and professional career. They, inevitably, focused themselves on the country life s social and cultural context, that could be better understood by living together with the teachers during the twenty-seven days I stayed in the Golfo s settlement, located in the town named Pacatuba/SE. The approach to the teachers lives through their stories and the daily contact proved how much Science is still distant from the peasants routine, sometimes being presented to them as a finished product . That way, the dialog between those two categories and the expectation of the country life s social and cultural conditions, together with the education, in which teachers have an essential role, still remain as a challenge
