ABSTRACT
Os métodos mistos de pesquisa são definidos como um processo de recolhimento, análise e "mistura" de dados quantitativos e qualitativos durante determinado estágio da pesquisa em um único estudo. Na área da Educação Física, esse método de pesquisa é uma combinação de abordagens relativamente nova. Assim, o presente ensaio teve como objetivo construir orientações fundamentais para o desenvolvimento de estudos de métodos mistos na área da Educação Física. Conclui-se, pois, que a busca pelo entendimento de como se dá o desenvolvimento de um estudo de métodos mistos pode auxiliar o pesquisador diante das construções de pesquisas, além de trazer contribuições para os avanços científicos.
Mixed research methods are defined as a process of collecting, analyzing and "mixing" quantitative and qualitative data during a given stage of research and in a single study. In the area of Physical Education, this research method is a relatively new combination of approaches. Thus, this essay aimed to build fundamental orientations for the development of mixed methods studies in the Physical Education area. It is concluded, therefore, that the search for the understanding of how the development of a mixed methods study takes place can help the researcher in the face of the research constructions, besides bringing contributions to the scientific advances.

Introdução: O teste de Stroop é comumente utilizado para avaliar a flexibilidade cognitiva e função executiva. O teste mostrou correlacionar-se com variáveis como idade, nível educacional e atividade física, porém, pouco se sabe sobre as variáveis relacionadas ao desempenho no teste em populações previamente ativas. Objetivo: Avaliar o desempenho no teste de Stroop em população fisicamente ativa. Métodos: 89 estudantes foram recrutados, os mesmos tiveram seus níveis de atividade física avaliado por questionário e composição corporal avaliada por bioimpedância. Resultado: Observamos que as variáveis relacionadas à prática de atividade física não apresentaram correlação com o teste de Stroop. Foi identificado correlação do teste com as variáveis peso corporal e índice de massa corporal (IMC), sendo que maiores valores de peso e IMC resultaram em melhor desempenho no teste. Conclusão: Para indivíduos fisicamente ativos, outros fatores parecem ser preponderantes à atividade física com relação ao desempenho no teste de Stroop.
Introduction: The Stroop test is commonly used to assess cognitive flexibility and executive function. The test was correlated with variables such as age, educational level and physical activity, but little is known about variables related to performance in this test in previously active populations. Objective: To evaluate Stroop performance in a physically active population. Methods: 89 recruited students had their physical activity levels assessed by questionnaire and body composition evaluated by bioimpedance. Result: We observed that variables related to the physical activity level did not present correlation with the Stroop test. Was identified correlation of the test with the variables body weight and body mass index (BMI), being that higher values of weight and BMI resulted in better Stroop performance. Conclusion: For physical active individuals, other factors may be preponderant to physical activity in relation to Stroop performance.

ABSTRACT CONTEXT AND OBJECTIVE: Sarcopenia is an emerging public health issue in Brazil. Because of its high prevalence and the lack of national data, the objective here was to identify cutoff points for appendicular skeletal muscle (ASM) and handgrip strength in relation to fear of falling among Brazilian older adults. DESIGN AND SETTING: Cross-sectional study; in the community. METHODS: Participants underwent morphological and functional evaluations; and were asked about previous falls and fear of falling. Different adjustments to ASM and handgrip strength were used. Slow walking speed was defined as < 0.8 m/s or 1.0 m/s. Gender and age groups were compared using t tests, analysis of variance (ANOVA), chi-square test or Fisher's exact test. Receiver operating characteristic curves were used to identify cutoffs for ASM and handgrip strength in relation to fear of falling. RESULTS: 578 older adults participated in this study. Function levels decreased with increasing age, and body composition differed between the sexes. In relation to fear of falling, the cutoffs for ASM adjusted for body mass index (BMI) were < 0.85 for men and < 0.53 for women; the cutoffs for absolute handgrip strength and relative handgrip strength (adjusted for BMI) were 30.0 kgf and 21.7 kgf, and 1.07 and 0.66, for men and women, respectively. CONCLUSION: The values presented can be used as references in clinical practice and research. We recommend use of ASM adjusted for BMI and choosing between absolute and relative handgrip strength for men and women, according to study needs.
