Este estudo objetivou avaliar a qualidade de vida de mototaxistas e sua relação com os aspectos psicossociais do trabalho. Estudo epidemiológico, transversal, realizado com 400 mototaxistas do Município de Jequié, Bahia, Brasil. Utilizou-se um formulário contendo dados sociodemográficos, o WHO Quality of Life-Bref Questionnaire (WHOQOL-Bref) e o Job Content Questionnaire (JCQ). Os resultados evidenciaram que mototaxistas com alto controle sobre o trabalho apresentaram melhor percepção de qualidade de vida no domínio psicológico; os que possuem alta demanda psicológica apresentaram melhor percepção de qualidade de vida nos domínios relações sociais e meio ambiente; aqueles com alta exigência e com trabalho ativo apresentaram melhor percepção de qualidade de vida nos domínios relações sociais e meio ambiente. Assim, o ambiente psicossocial do trabalho, e, especialmente, o controle sobre o trabalho, são importantes determinantes da percepção da qualidade de vida dos mototaxistas.
ABSTRACT:The objective of this study was to analyze the relationship of sociodemographic characteristics and activity overload with the quality of life of relative caregivers of elderly dependents at home. This is an epidemiological, transversal study, conducted with 58 relative caregivers of elderly people registered in Family Health Programs in a municipality in the state of Bahia. Sociodemographic data were collected; in addition, the Katz Index of Independence, Zarit Burden Interview, and WHOQOL-bref were administered. The data were analyzed using correlation and multiple linear regression. The Zarit scale was negatively associated with all areas of the WHOQOL-bref domain, which was corroborated by the multiple regression model, which identified that the Zarit scale alone was able to predict the impact of care on quality of life of the studied caregivers. There is evidence of a need for expansion of social and health support to caregivers in an attempt to minimize overload, improving the quality of life of these individuals. DESCRIPTORS: CALIDAD DE VIDA DE FAMILIARES CUIDADORES DE ANCIANOS DEPENDIENTES EN CASARESUMEN: Se objetivó analizar la asociación de las características socio-demográficas y sobrecarga de actividades con la calidad de vida de familiares cuidadores de ancianos dependientes en casa. Estudio epidemiológico, transversal, realizado con 58 cuidadores familiares de personas mayores, registrado en Estrategias de Salud de la Familia, de un municipio del estado de Bahía. Los datos fueron recolectados por medio de instrumentos sociodemográficos, además del Katz Index of Independence, Zarit Burden Interview, y el WHOQOL-bref, que fueron analizados mediante estadística descriptiva, de correlación y regresión lineal múltiple. La escala Zarit se asoció negativamente con todas las áreas del WHOQOL-bref. Corroborando este hallazgo, el modelo de regresión múltiple aplicado identificó que la escala Zarit sola es capaz de predecir el impacto del cuidado sobre la calidad de vida de los cuidadores estudiados. Hay evidencia de la necesidad de expansión de la ayuda social y de la salud a los cuidadores, en un intento de minimizar la sobrecarga, mejorando la calidad de vida de estos individuos. DESCRIPTORES:Cuidadores. Familia. Anciano. Calidad de vida. Apoyo social.
The purpose of this study was to determine the effects of creatine supplementation and exercise on the integrity of muscle fiber, as well as the effect of the supplementation on the creatine kinase (CK) assay measurement. Forty-nine sedentary individuals participated in a double-blind study and were divided into two groups: C (n=26) received 4x5-day packages of 0.6 g.kg -1 of body weight contained 50% of creatine + 50% of dextrose, and P (n=23) received packages containing only dextrose. On the first day the groups performed a 1RM test for bench press, seated row, leg extension, leg curl and leg press. On D 7 they received the supplements. On the fourteenth day, they performed a training session of five exercises, each in three sets of ten repetitions at 75% of 1RM. Blood was collected before (D 14 ) and after the exercise session (D 15 ). Differing levels of blood creatine were tested to determine the influence on the assay measurements of CK. ANOVA and Tukey's post-hoc tests were used to compare groups and different times of study protocol (P<0.05). No changes were observed in CK activity of the groups from D 0 , D 7 and D 14 . On D 15 CK activity increases 140% (women) and 200% (men). There was no difference in CK activity between groups. Blood creatine levels up to 5mM produced no significant effect on CK assay results. CK activity increased after resistance exercise, while creatine supplementation produced no difference in the muscle cellular integrity nor compromised assay methodology.Uniterms: Physical exercise/effects.

Quarenta e nove sedentários participaram de um estudo duplo-cego e foram divididos em dois grupos: C (n=26) que receberam 4x5 dias embalagens com 0,6 g.kg -1 de massa corporal com 50% de creatina + 50% de dextrose, e P (n=23) que receberam embalagens contendo apenas dextrose. No primeiro dia, eles realizaram o teste de 1RM para os exercícios supino reto, remada sentada, cadeira extensora, mesa flexora, e leg press. No D 7 receberam os suplementos. No décimo quarto dia eles realizaram uma sessão de treinos com os cinco exercícios, cada um com 3x10 repetições a 75% de 1RM. Sangue foi coletado antes (D 14 ) e depois da sessão de exercícios (D 15
The performance of "chair stand test" showed predictive ability for sarcopenia, being an effective and simple screening tool for sarcopenia in elderly women. This test could be used for screening sarcopenic elderly women, allowing early interventions.
