    This study aimed to analyze the social representations in the professionals of technical staff, who work with children at USP daycare centers. Eight professionals of the nursing field underwent a semi-structured interview. The interviews were recorded and transcribed in their entirety and the content of the discourse was subjected to thematic-categorical analysis. The categories were transformed into variables and processed by the software Classification Hiérarchique Classificatoire et Cohésitive (CHIC®) and analyzed by the hierarchical similarity tree. The results indicate that actions to promote health are reported as educational and transformative, in which health care gains new meaning through contextualized conceptions in the field of child education. We conclude that professionals attribute new meanings to their practices in the health care environment of daycare centers as their representations shifts from the logic of the biomedical field to a logic of educational care. In this sense, they perceive themselves as being challenged to establish an interaction with the children in terms of their activities related to the promotion of health and in an educational act.O estudo teve como objetivo analisar as representações sociais dos profissionais das equipes técnicas que trabalham nas creches da Universidade de São Paulo (USP). Foram entrevistados oito profissionais da área de enfermagem com o uso de um roteiro semiestruturado. As entrevistas foram gravadas e transcritas na íntegra e o conteúdo submetido à análise de conteúdo temático-categorial. As categorias foram transformadas em variáveis, processadas pelo software Classification Hiérarchique Classificatoire et Cohésitive (CHIC®) e analisadas pela árvore hierárquica de similaridade (cluster multinível). Os resultados indicam que as ações acerca da promoção à saúde são relatadas como educativas e transformadoras, em que o cuidado em saúde ganha novos significados por meio de concepções contextualizadas no campo da educação infantil. Conclui-se que os profissionais ressignificam suas práticas de cuidado em saúde no ambiente das creches em que as representações transitam da lógica biomédica do cuidar para uma lógica educativa do cuidado. Neste sentido, se percebem desafiados na interação que estabelecem com as crianças acerca de sua atuação vinculada à promoção da saúde e ao ato de educar.El objetivo de la investigación estudio fue analizar las representaciones sociales de los técnicos profesionales que trabajan en los centro de atención infantil de la Universidad de São Paulo (USP). Ocho profesionales de enfermería fueron entrevistados mediante un semi-estructurada guión. Las entrevistas fueron grabadas y transcritas y sometidas al análisis de contenido temático-categorial. Las categorías se transformaron en variables procesadas por hiérarchique Classificatoire et Cohesiva software Clasificación (CHIC®) y analizados por similitud árbol jerárquico (clúster de múltiples niveles). Los resultados indican que las acciones sobre promoción de la salud se reportan como educativo y transformador, en que la atención de la salud adquiere nuevos significados a través de concepciones contextualizadas en el campo de la educación infantil. Llegamos a la conclusión de que los profesionales atribuyen nuevos significados a sus prácticas en el ámbito sanitario de los centro de atención infantil sus representaciones turnos desde la lógica del campo de la biomedicina a la lógica de la atención educativa. En este sentido, los propios que perciben al ser desafiados a establecerse una interacción con los niños en términos de sus actividades relacionadas con la promoción de la salud y en un acto educativo

    Objective: To compare the cardiovascular responses to passive postural maneuvers (tilt test) and the cardiorespiratory capacity in middle-aged men and women, before and after aerobic physical training. Methods: Seven men (44.6±2.1 years old) and seven women (51.7±4.8 years old) participated in aerobic physical training for 12 weeks. The tilt test protocol (five minutes supine, ten minutes tilted at 70° and five minutes supine) was followed, with arterial blood pressure and heart rate monitoring. A cycle ergometer protocol was used to measure cardiorespiratory capacity. Results: In the sedentary condition, men showed greater parasympathetic influence in heart rate control, as demonstrated by their higher RR interval (iRR) during the tilt test. After training, the iRR values became more similar in the two groups, although the women had higher iRR in the supine position and the men continued to present higher iRR under tilted conditions. The women's blood pressures continued to be higher after training, but heart rate tended to become similar in the two groups. The cardiorespiratory capacity patterns in the two groups were similar after training. Except for absolute heart rate values, for which there were no differences between the groups, the men's values were higher than those of the women for all other variables. It was also observed that, after the training, the women's blood pressures were significantly lower, even though their pressures remained higher than the men's. Conclusions: The training seemed to reduce the women's arterial blood pressure levels and improve both groups' cardiorespiratory capacity, but the men continued to present better performance than the women.125392400Pollock, M.L., Dawson, G.A., Physiologic responses of men 49 to 65 years of age to endurance training (1976) J Am Geriatr Soc, 24 (3), pp. 97-104Haddock, B.L., Marshak, H.P.H., Mason, J.J., Blix, G., The effect of hormone replacement therapy and exercise on cardiovascular disease risk factors in postmenopausal women (2000) Sports Med, 29 (1), pp. 39-49Liu, C.C., Kuo, T.B., Yang, C.C., Effects of estrogen on gender-related autonomic differences in humans (2003) Am J Physiol Heart Circ Physiol, 285 (5), pp. H2188-H2193Rosano, G.M., Vitale, C., Fini, M., Hormone replacement therapy and cardioprotection: What is good and what is bad for the cardiovascular system?

Methods To describe the narrative method within the qualitative research. Results The qualitative research method is characterized by addressing issues related to the singularities of the field and individuals investigated, being the narrative interviews a powerful method for use by researchers who aggregate it. They allow the deepening of research, the combination of life stories with socio-historical contexts, making the understanding of the senses that produce changes in the beliefs and values that motivate and justify the actions of possible informants. Conclusion The use of narrative is an advantageous investigative resource in qualitative research, in which the narrative is a traditional form of communication whose purpose is to serve content from which the subjective experiences can be transmitted.Objetivo Este trabalho consiste numa contribuição metodológica em que se explicitam e se enfatizam o alcance e a fecundidade da entrevista narrativa no âmbito da investigação de natureza qualitativa.
