There is evidence that the level of physical fitness of children and adolescents has declined over time. In this sense studies that verify the secular trend of growth and physical fitness gain importance. Objective: to analyze, through a secular tendency, changes occurred in parameters of physical fitness related to health in schoolchildren from 7 to 12 years of age in the city of Taguatinga- DF, from 1992 to 2015. Materials and Methods: The study addresses With a sample of 2,281students (1,114 males and 1,167 females), from 2001 to 2005 (years 2000) with 774 students (348 boys and 426 girls) and Year of 2015 with 370 students (187 boys and 183 girls), totaling 3,425 students (1649 boys and 1,776 girls). Body mass and height were obtained, which gave rise to the body mass index, tricipital and subscapular skinfolds, with which the percentage of fat was calculated, in addition to agility, flexibility, lower limb strength and sexual maturation. Means, deviations and frequency were analyzed. Normality was verified with Shapiro Wilks and Kolmogorov-Smirnov. In addition to the analysis of variance in case of normality and Kruskal Wallis where there was no normality. The study was approved by the Ethics Committee of the Catholic University of Brasilia under number 1,086,406. Results: Body mass, height, body mass index and fat percentage of boys and girls presented significant differences when we compared the three moments of the study. These variables showed a positive secular trend, mainly when we compare the years 1990 and the year 2015. The results also show that when compared with reference tables for ages and sex the majority are classified in unsatisfactory levels. The variables flexibility and horizontal jump presented a seculartendency negative, demonstrating a worsening of results over time. There was also worsening in the variable agility that presented a positive secular tendency. It was found that the boys in the sample are initiating the process of sexual maturation earlier than the girls. The boys presented better performance in all stages of sexual maturation, except for the variable flexibility, where the girls were better. Conclusions: In a qualitative analysis, the results of the secular trend of both physical growth and motor performance of boys and girls presented worse results when we compared the first moment of the study (1990s) with the present moment (2015). It is suggested a great attention to the objectives of the Physical Education classes at the Public School and a pedagogical supervision to the teachers who teach this discipline. / Introdu????o: As evolu????es tecnol??gicas ocorridas no mundo moderno provocaram mudan??as significativas na forma como crian??as e adolescentes realizam suas divers??es e lazer, levandoos ?? diminui????o do n??vel de atividade f??sica e prejudicando a forma????o de h??bitos saud??veis. H?? evid??ncias que o n??vel de aptid??o f??sica das crian??as e dos adolescentes tem diminu??do com o tempo. Neste sentido estudos que verifiquem a tend??ncia secular do crescimento e da aptid??o f??sica ganham import??ncia. Objetivo: analisar, por meio de tend??ncia secular, modifica????es ocorridas em par??metros da aptid??o f??sica relacionada ?? sa??de em escolares de 07 a 12 anos de idade na cidade de Taguatinga-DF, no per??odo de 1992 a 2015. Materiais e M??todos: O estudo aborda tr??s momentos distintos, de 1992 a 1995 (anos 1990) com uma amostra de 2.281 alunos(1.114 do sexo masculino e 1,167 do sexo feminino), de 2001 a 2005 (anos 2000) com 774 alunos (348 meninos e 426 meninas) e do ano de 2015 com 370 alunos (187 meninos e 183 meninas), totalizando 3.425 alunos (1649 meninos e 1.776 meninas). Foram coletados massa corporal e estatura, que deram origem ao ??ndice de massa corporal, dobras cut??neas tricipital e subescapular, com as quais foi calculado o percentual de gordura, al??m da agilidade, flexibilidade, for??a de membros inferiores e matura????o sexual. Foram analisadas m??dias, desvios e frequ??ncia. A normalidade foi verificada com Shapiro Wilks e Kolmogorov-Smirnov. Al??m da an??lise de vari??ncia em caso de normalidade e Kruskal Wallis onde n??o houve normalidade. O estudo foi aprovado pelo Comit?? de ??tica da Universidade Cat??lica de Bras??lia sob o n??mero 1.086.406. Resultados: A massa corporal, a estatura, o indice de massa corporale o percentual de gordura dos meninos e das meninas apresentaram diferen??as significativas quando comparamos os tr??s momentos do estudo. Estas variaveis apresentaram tend??ncia secular positiva, principalemtne quando comparamos os anos 1990 e o ano de 2015. Os resultados tamb??m mostram que quando comparados com tabelas referenciais para as idades e sexo a maioria est??o classificados em niveis insatisfat??rios. As vari??veis flexibilidade e salto horizontal apresentaram tendencia secular negativa, demonstrando uma piora de resultados ao longo do tempo. Tamb??m houve piora na variavel agilidade que apresentou tendencia secular positiva. Verificou-se que os meninos da amostra est??o iniciando mais cedo o processo de matura????o sexual do que as meninas. Os meninos apresentaram melhor desempenho em todos os est??gios de matura????o sexual, exceto para a variavel flexibilidade, onde as meninas foram melhores. Conclus??es: Numa an??lise qualitativa, os resultados de tendencia secular tanto de crescimento f??sico quanto de desempenho motor dos meninos e meninas apresentaram resultados piores quando comparamos o primeiro momento do estudo (anos 1990) com o momento atual (2015). Sugere-se uma aten????o muito grande aos objetivos das aulas de Educa????o F??sica a Escola P??blica e uma supervis??o pedag??gica aos professores que ministram esta disciplina.

A primeira foi conduzida com o objetivo de avaliar as caracter?sticas de qualidade da carne de bovinos cruzados Wagyu ? Angus (Red). A segunda foi conduzida com o objetivo de verificar os efeitos da matura??o de maminha de alcatra de Nelore em diferentes temperaturas (0?C e 4?C) e tempos (0 = carne fresca com 24 horas, 7, 14, 21 e 28 dias). Na primeira pesquisa foi analisada a carne dos m?sculos Longissimus thoracis, Semitendinosus e Triceps brachii obtidas do abate de machos castrados e de f?meas, aos 24 meses de idade. Na desossa foram mensurados no m?sculo Longissimus thoracis a espessura de gordura subcut?nea, cor da gordura (L*a*b*, C, H?), a ?rea de olho de lombo e escore para o grau de marmoriza??o. Foram analisados o pH final, a capacidade de reten??o de ?gua, a perda de peso por cozimento, a for?a de cisalhamento, cor (L*a*b*, C, H?) e os teores de umidade, massa seca, res?duo mineral fixo, prote?na e gordura. Por??es de carne do m?sculo Longissimus thoracis foram coletadas avaliar o efeito dos tempos de sete e 14 dias de matura??o no pH final, na capacidade de reten??o de ?gua, na perda de peso por cozimento, na for?a de cisalhamento, na cor da carne (L*a*b*, C, H?) e na cor da gordura (L*a*b*, C, H?). Para a carne de todos os m?sculos n?o houve efeito de sexo no pH final, na capacidade de reten??o de ?gua, na perda de peso por cozimento e no teor de prote?na. O Longissimus thoracis de f?meas recebeu os melhores escore para marmoreio, apresentou maior teor de gordura e menor for?a de cisalhamento e no Longissimus thoracis de machos apresentou maior ?rea de olho de lombo. A matura??o da carne do Longissimus thoracis proporcionou redu??o na for?a de cisalhamento e aumento do pH final. Na segunda pesquisa, por??es de carne (? 400 gramas) foram embaladas, a v?cuo, e estocadas em c?mara frigor?fica nas temperaturas (0?C e 4?C). Foram mantidas nestas temperaturas por 7, 14, 21 e 28 dias. Foram analisados o pH, capacidade de reten??o de ?gua, perda de peso por cozimento, for?a de cisalhamento, cor (L*, a*, b*, C, H?). N?o houve varia??o no pH em fun??o da temperatura utilizada. Entretanto, o pH aumentou com o decorrer do tempo de matura??o. Foi observada varia??o na luminosidade da carne em fun??o da temperatura, sendo menor a luminosidade na carne maturada a 0?C. O teor de vermelho desta carne aumentou linearmente em fun??o do tempo de matura??o e tamb?m foi influenciada pelas temperaturas de matura??o, sendo maior quando maturada a 0?C. A perda de peso por cozimento tamb?m apresentou aumento linear ao longo do tempo de matura??o. A capacidade de reten??o de ?gua e a for?a de cisalhamento apresentaram redu??o linear ao longo do tempo de matura??o. A matura??o por 28 dias ocasionou redu??o na for?a de cisalhamento da maminha de alcatra. Recomenda-se maturar a maminha de alcatra por 28 dias em temperatura de 4?C. / Disserta??o (Mestrado) ?

Dissertation Dissertation (Master?s degree in Animal Science (Master?s degree in Animal Science (Master?s degree in Animal Science (Master?s degree in Animal Science (Master?s degree in Animal Science (Master?s degree in Animal Science (Master?s degree in Animal Science (Master?s degree in Animal Science (Master?s degree in Animal Science (Master?s degree in Animal Science (Master?s degree in Animal Science (Master?s degree in Animal Science (Master?s degree in Animal Science (Master?s degree in Animal Science (Master?s degree in Animal Science ). This paper was drawn up on the results of two surveys. The first was conducted in order to evaluate the quality characteristics of meat from crossbred cattle Wagyu ? Angus (Red). The second was conducted in order to verify the effects of maturation titty rump Nellore at different temperatures (0 ? C and 4 ? C) and time (0 = fresh meat with 24 hours, 7, 14, 21 and 28 days ). In the first study we analyzed the meat of Longissimus thoracis, Semitendinosus and Triceps brachii obtained from the slaughter of castrated males and females, at 24 months old. The bones were measured in the Longissimus thoracis muscle to fat thickness, color of fat (L * a * b *, C, H?), rib eye area and score to the degree of marbling. The final pH were analyzed, water retention capacity, weight loss by cooking, shear strength, color (L * a * b *, C, H?), and the moisture content, dry matter, mineral residue fixed, protein and fat. Meat portions of Longissimus thoracis muscle were collected to evaluate the effect of seven days and 14 days of aging at the end pH, water retention capacity, weight loss by cooking, the shear force on the meat color (L * a * b *, C, H?) and fat color (L * a * b *, C, H?). For the meat of all muscles of no gender effect on the ultimate pH, water retention capacity, by cooking weight loss and protein content. The Longissimus thoracis females received the best score for marbling, showed higher fat content and lower shear strength and Longissimus thoracis males showed greater loin eye area. The maturation of the meat of Longissimus thoracis provided a reduction in shear force and increase in final pH. In the second study, cam portions (400 ? grams) were packed, vacuum, and stored in the cold room temperatures (0 ?C and 4 ?C). They were maintained at these temperatures for 7, 14, 21 and 28 days. They analyzed the pH, water holding capacity, cooking weight loss, shearing force, color (L *, a *, b *, C, M ?). There was no variation in pH as a function of temperature used. However, the pH increase during maturation time. It was observed variation in brightness of the flesh a function of temperature being lower in brightness aged meat at 0 ?C. The content of this red meat increased linearly as a function of aging time and was also influenced by the temperature of ripeness, being higher when aged at 0 ?C. The cooking weight loss also showed a linear increase over time of aging. The water retention capacity and shear strength showed a linear decrease over time of aging. Maturation for 28 days decreased the shear force of titty rump. It is recommended to mature titty rump for 28 days in temperature
