Abstract Sarcopenia affects performance in simple activities of daily life, directly impacting the quality of life of the elderly. The objective of the present study was to analyse the correlation between age, sarcopenia index and functional capacity in community-dwelling elderly. The sample comprised 40 community-dwelling elderly, 12 men (69.16± 8.13 years) and 28 women (67.96± 6.23 years). All participants underwent the Electrical Bioimpedance (BIA), Handgrip Strength test (HS), and Timed-Up-and-Go test (TUG). A strong correlation was found between age x TUG in men (r= 0.733; p= 0.021), between age x fat mass in women (r= 0.775; p= 0.032), between HS and TUG in men (r= − 0.713; p= 0.0003), and a weak correlation between HS and Free Fat Mass in women (r= 0.394; p= 0.043). Weak negative correlations were found regarding age in both men and women. In functional performance, concerning test time and age, strong correlations were found for men and weak correlations for women.

RESUMO O presente artigo teve como objetivo compreender os sentidos/significados das brincadeiras de luta como práticas corporais vivenciadas no cotidiano de crianças do 1o ao 5o ano de uma escola pública da cidade de São Luís do Maranhão. Para tanto, propusemos um estudo de natureza qualitativa, a partir de uma pesquisa de campo, utilizando da observação participante, sob a referência de estudos da sociologia da infância. Foram identificadas 7 classificações de brincadeiras de luta a partir da análise de 27 episódios registrados e de desenhos produzidos pelas crianças. Concluímos que os sujeitos representam nas “lutinhas” aspectos forjados no cotidiano, (re)criando e compartilhando conceitos de lúdico e violência bem como das lutas como acervos das culturas infantis.

ABSTRACT This article aimed to understand the senses / meanings of play fights as bodily practices experienced in the daily lives of children from the 1st to the 5th year of a public school in the city of São Luís do Maranhão. For that, we proposed a qualitative study, based on field research, using participant observation, under the reference of sociology of childhood studies. Seven classifications of play figths were identified based on the analysis of 27 recorded episodes and drawings produced by the children. We conclude that the subjects represent in the “little fights” aspects forged in daily life, (re) creating and sharing concepts of playfulness and violence, as well as the struggles as collections of children's cultures.

RESUMEN Este artículo tuvo como objetivo comprender los sentidos / significados de los juegos de lucha como prácticas corporales vividas en la vida cotidiana de los niños de 1º a 5º año de una escuela pública de la ciudad de São Luís do Maranhão. Para ello, se propuso un estudio cualitativo, a partir de una investigación de campo, utilizando la observación participante, bajo la referencia de los estudios de sociología de la infancia. Se identificaron siete clasificaciones de juegos de lucha a partir del análisis de 27 episodios registrados y dibujos realizados por los niños. Concluimos que los sujetos representan en las “pequeñas luchas” aspectos forjados en la vida cotidiana, (re) creando y compartiendo conceptos de alegría y violencia, así como las luchas como colecciones de culturas infantiles.

Resumo O objetivo desta pesquisa é compreender as brincadeiras de lutinha e as brigas vivenciadas no ambiente escolar, sob a perspectiva do cotidiano infantil, em um Centro de Atenção Integral à Criança e ao Adolescente, situado em Sobradinho II - DF. O estudo tem natureza qualitativa, de orientação etnográfica, com os aportes teórico-metodológicos das sociologias do cotidiano e da infância. O trabalho de campo foi realizado ao longo de sete meses do ano letivo de 2017, com trinta e quatro crianças, entre nove e 12 anos de idade. Os instrumentos utilizados foram observação participante, produção de desenhos e conversas com as crianças. Os registros de campo permitiram a identificação de categorias que evidenciam as brincadeiras de lutinha e as brigas sob dimensões paradoxais do cotidiano infantil, que carregam no seu bojo aspectos circundantes ao conflito enquanto mediador das relações concebidas dentro e fora da escola.

Abstract This study looks into children’s play-fighting and real fights experienced in the school environment from the perspective of children’s daily life in a Center for Whole Attention to Children and Adolescents located in Sobradinho II, DF, Brazil. It is a qualitative, ethnographic study with theoretical-methodological contributions from Sociologies of Daily Life and Childhood. Field research was conducted over seven months of the 2017 school year, with 34 children aged 9-12. The instruments used were participant observation, drawing, and conversations with the children. Field records allowed identifying categories that show play-fighting and real fights under the paradoxical dimensions of children’s daily life, which carry aspects surrounding conflict as a mediator of relationships conceived inside and outside the school.

Resumen El objetivo de esta investigación es comprender los juegos de lucha y las peleas vivenciadas en el ambiente escolar, bajo la perspectiva del cotidiano infantil, en un Centro de Atención Integral a Niños y Adolescentes, situado en Sobradinho II - DF. El estudio tiene naturaleza cualitativa, con orientación etnográfica y con los aportes teórico-metodológicos de las sociologías de lo cotidiano y de la infancia. La investigación de campo fue realizada a lo largo de siete meses del año 2017, con treinta y cuatro niños de entre 9 y 12 años de edad. Los instrumentos utilizados fueron la observación participante, la producción de dibujos y las conversaciones con los niños. Los registros de campo permitieron la identificación de categorías que evidencian los juegos de lucha y las peleas bajo dimensiones paradójicas del cotidiano infantil, que cargan aspectos circundantes al conflicto como mediador de las relaciones concebidas dentro y fuera de la escuela.

SUMMARY: We investigated the effect of the intervention using the BFR method on functional capacity after 16 weeks in elderly women. In a controlled clinical trial, 23 women were randomly allocated into two groups, low-intensity exercise with blood flow restriction (LI + BFR, N = 11, Age: 69.40 ± 5.73) and control group (CG, N = 12, Age: 69.00 ± 6.39). The LI + BFR group had a volume of 75 repetitions at 20-30 % of 1RM and 3-4 sets per exercise (30, 15, 15 and repetitions with 30" rest between sets). The CG did not undergo any type of exercise. Functional capacity, anthropometry and sarcopenia were verified through a battery of tests before and after 16 weeks. The LI + BFR group had significant improvement in performance in Handgrip strength, Chair Stand, Arm curl, 2.44 Up-and-Go and 6 min walk, Sit-andreach and Back Scratch (p<0.05) after the intervention. The elderly women were still classified as sarcopenic, despite the improvement in the Muscle Mass Index (p<0.01). CG did not present significant changes. The BFR method can be an effective in the intervention process using physical exercise as an auxiliary strategy in the control of sarcopenia, providing a physical profile during the aging process.

RESUMEN: Investigamos en mujeres ancianas el efecto de la intervención utilizando el método de restricción del flujo sanguíneo en la capacidad funcional, después de 16 semanas. En un ensayo clínico controlado, 23 mujeres fueron asignadas aleatoriamente en dos grupos; ejercicio de baja intensidad con restricción de flujo sanguíneo (BI + RFS, N = 11, edad: 69,40 ± 5,73) y grupo control (GC, N = 12, Edad: 69,00 ± 6,39). El grupo BI + RFS tuvo un volumen de 75 repeticiones al 20-30 % de 1RM y 3-4 series por ejercicio (30, 15, 15 y repeticiones con 30 " de descanso entre series). El GC no fue sometido a ningún tipo de ejercicio. La capacidad funcional, la antropometría y la sarcopenia se verificaron mediante una batería de pruebas antes y después de 16 semanas. El grupo BI + RFS tuvo una mejora significativa en el rendimiento de la fuerza de la empuñadura, soporte de la silla, curvatura del brazo, 2,44 up-and-go y 6 min, ‘sit-and-reach’ ‘Back Scratch’ (p<0,05) después de la intervención. Las mujeres de edad avanzada seguían clasificadas como sarcopénicas, a pesar de la mejora en el índice de masa muscular (p<0,01). El GC no presentó cambios significativos. El método de restricción del flujo sanguíneo puede ser efectivo en el proceso de intervención utilizando ejercicio físico como estrategia auxiliar en el control de la sarcopenia, proporcionando un perfil físico durante el proceso de envejecimiento.

The aim of the study was to verify the systolic, diastolic and mean arterial pressure response in elderly women during isokinetic test. The study included 54 females (68.8 ± 5.9 years) divided into two age groups (Group 1: 60 to 70 and group 2: above 71 years). BP was measured before and immediately after the isokinetic knee extension / flexion test in the concentric-concentric mode. After the test, significant elevations were observed in relation to the pre-test in SBP (G1: ?% = 29.7%, G2: ?% = 20.6%, p <.01, respectively) and in MAP (G1: ?% = 7.6 %, G2: ?% = 8.4%, p <.01, respectively). The use of isokinetic tests produces elevations in systolic blood pressure and mean arterial pressure in elderly women. Increases occur independently of the age group studied. However, the increases detected do not appear to be of sufficient magnitude to constitute a health hazard whereby isokinetic tests can be safely applied in this population.
