RESUMO Objetivou-se com esta pesquisa analisar o uso da técnica de Análise de Conteúdo nas produções científicas veiculadas em periódicos da Educação Física brasileira. Recorreu-se a uma pesquisa exploratório-descritiva, que teve como corpus empírico de análise 222 artigos publicados no período de 2007 a 2017. Os principais resultados indicam crescimento no uso da técnica, Laurence Bardin como principal referência e poucos índices de explanação da técnica metodológica. Conclui-se que a Análise de Conteúdo ganhou espaço no campo da Educação Física ao longo dos anos, as pesquisas apresentam a técnica de forma breve e têm incorporado o apoio de softwares nas análises, mas ainda com pouca representatividade.

ABSTRACT This research aimed to analyse the use of Content Analysis (CA) in scientific publications by journals in area of Physical Education in Brazil. The method was exploratory and descriptive; and analysis was carried out in an empirical corpus of 222 articles published between 2007 and 2017. Main results suggested a growth in the use of that technique, i.e., being Laurence Bardin the principal reference, as well as low rate of explanation attributed to chosen methodological technique. Therefore, CA has gained space in Physical Education field throughout years, as research has presented its practice in a brief form and it has used software support into the stage of analysis, even though it shows low representativeness.

RESUMEN El objetivo de esta investigación fue analizar el uso de la técnica de Análisis de Contenido en producciones científicas publicadas en revistas brasileñas de Educación Física. Se utilizó una investigación exploratoria-descriptiva, con el corpus empírico de análisis 222 artículos publicados de 2007 a 2017. Los principales resultados indican un crecimiento en el uso de la técnica, Laurence Bardin como principal referente y pocos índices de explicación de la técnica metodológica. Se concluye que el Análisis de Contenidos ha ganado espacio en el campo de la Educación Física a lo largo de los años, las investigaciones presentan brevemente la técnica y ha incorporado el soporte del software en los análisis, pero aún con poca representatividad.

Resumo A pesquisa teve como objetivo investigar como as produções científicas veiculadas por periódicos no período de 2000 a 2017 têm analisado o currículo de formação em Educação Física. Foi realizada uma pesquisa do tipo bibliográfica em dez periódicos classificados no Qualis Capes de A1 a B3 em Educação Física e analisados o título, o resumo e as palavras-chave de 230 artigos. Para a análise dos dados foi empregada a análise de conteúdo. O nível de desenvolvimento curricular mais analisado foi o currículo realizado, caracterizado por conhecimentos aprendidos pelos estudantes. Nenhuma pesquisa analisou o currículo avaliado. O tema mais investigado foi “Disciplinas dos cursos”, e a maioria das pesquisas não utiliza referências para conceituar currículo. Sugere-se maior articulação entre os níveis do currículo com ênfase no currículo avaliado.

Abstract This study investigated how scientific works published in 2000-2017 analyzed the curriculum for training Physical Education teachers. Bibliographic research was carried out in ten Physical Education journals classified as A1-B3 by Qualis Capes. Titles, abstracts and keywords of 230 articles were submitted to content analysis. The most widely analyzed curriculum development level was the so-called “realized curriculum”, i.e. knowledge learned by students, while the so-called “evaluated curriculum” was not analyzed. The most widely investigated topic was course subjects and most of the research does not use any reference to conceptualize curriculum. Better coordination between curriculum levels is suggested, with emphasis on the evaluated curriculum.

Resumen Este trabajo tuvo como objetivo investigar cómo las producciones científicas divulgadas por periódicos en el período de 2000 a 2017 han analizado el currículo de formación en Educación Física. Se realizó una investigación de tipo bibliográfica en diez periódicos clasificados en el Qualis Capes de A1 a B3 en Educación Física y fueron analizados el título, el resumen y palabras clave de 230 artículos. Para el análisis de los datos se empleó el análisis de contenido. El nivel de desarrollo curricular más analizado fue el currículo realizado, caracterizado por conocimientos aprendidos por los estudiantes. Ninguna investigación analizó el currículo evaluado. El tema más investigado fue el de disciplinas de los cursos y la mayoría de las investigaciones no utiliza referencias para conceptuar currículo. Se sugiere una mayor articulación entre los niveles del currículo con énfasis en el currículo evaluado.

ABSTRACT In this study, we evaluated the effects of substitution of partial and total spray-dried blood plasma (BP) with soy protein concentrate (SPC) in the diet of post-weaning piglets on their performance, intestinal histomorphometry, and blood parameters. Fifty-four castrated male piglets, weaned at an average age of 21 days and an initial average weight of 7.01±0.294 kg, were distributed in a completely randomized block design, with three diets (0%SPC-5%BP, 2.5%SPC-2.5%BP, and 5%SPC-0%BP), six replicates, and three piglets per experimental unit. The experimental feeds were formulated to meet the requirements of the piglets at 21-32 and 33-42 days of age (pre-starter diet) and 43-66 days of age (starter diet). From 21 to 32 and 21 to 42 days of age, daily feed intake, daily weight gain, and final weight of the animals were higher in the group fed 2.5%SPC-2.5%BP and 0%SPC-5%BP. From 21 to 66 days of age, daily weight gain and daily feed intake were higher in the animals fed 2.5%SPC-2.5%BP. No effect was observed on the histomorphometry variables. The total leukocyte count was higher in animals fed 2.5%SPC-2.5%BP and 5%SPC-0%BP and the lymphocyte count was lower in the piglets that received 0%SPC-5%BP. The combined use of soy protein concentrate and spray-dried blood plasma in the feeds of piglets between 21 and 42 days of age improves their productive performance.

ABSTRACT Seventy-two barrows were used to evaluate the effects of the use of soy protein concentrate (SPC) in diets of post-weaning piglets on their performance, intestinal histomorphometry, and blood parameters. Piglets were weaned at 21 days of age and distributed in a randomized-block experimental design with four treatments (0, 3, 6, and 9% SPC), six replications, and three piglets per replication. Diets were formulated to meet the requirement of the piglets according to phases of 21 to 32, 33 to 42, and 43 to 66 days of age. Both feed and water were provided ad libitum during the entire experiment. The feed of the phase of 43 to 66 days was based on corn and soybean meal. In the period between 21 and 32 days of age, the use of SPC in the diet did not impact the daily weight gain (DWG) or the daily feed intake (DFI) of the piglets, whereas there was a linear effect on feed conversion (FC), which decreased as the levels of SPC in the feed were increased. In the period between 33 and 42 days of age, a linear effect was observed on FC, which increased as the level of SPC in the feed was increased. In this period, no effects of SPC were observed on DWG or DFI. Inclusion of SPC in the diets does not influence performance, intestinal histomorphometry, or blood parameters of piglets in the period between 21 and 66 days of age.
