Introdução: A inatividade física é um dos principais fatores etiológicos da morbilidade
e mortalidade, na sociedade atual. A atividade física é uma grande aliada no controlo do
peso e prevenção da obesidade, diminui o risco de desenvolver doenças cardiovasculares,
diabetes, aumentando a capacidade cardiorrespiratória e a probabilidade de viver mais
anos e de forma mais saudável. Este trabalho, visa conceber e testar uma proposta
metodológica, para caracterizar e analisar as associações dos diferentes fatores
cardiometabólicos e nutricionais, com os hábitos de atividade física, considerando 3
grupos distintos (sedentários, caminhantes e caminhantes com pratica de atividade física
regular e estruturada).
Objetivo: Numa primeira fase, procedeu-se ao levantamento e confrontação entre
diferentes metodologias e instrumentos de quantificação das variáveis em estudo,
selecionado de forma sustentada na literatura a conceção da proposta metodológica. Para
testagem e determinação da consistência dos instrumentos, dos procedimentos
protocolares e da equipa de avaliação, recorreu ao desenvolvimento do estudo piloto em
população adulta (idade entre os 18 e os 35 anos), de ambos os sexos. Neste contexto, no
estudo piloto foram avaliados, os dados sociodemográficos, estado de saúde em geral,
ingestão alimentar (Block & Subar, 1992) (n=30), a prática de atividade física (Baecke,
Burema & Frijters, 1982) (n=38), medições antropométricas (Fragoso & Vieira,
2005) (n=27) e aptidão cardiorrespiratória (YMCA) (Golding, Myers, & Sinning,
1989) (n=23). Conclusão: O coeficiente de correlação intraclasse (763 ³R≥1.000; p <.05) e de Pearson
(.457³ r≥.704; p<.05), revelaram-se elevados, bem como reduzidos valores Erro Técnico
de Medida (.028>ETM<1.982), Erro Mediano (-.225>‘Me error’<2.392) e Coeficiente de
variação (.156%>CV<6.275%), testam a consistência e fiabilidade dos procedimentos
protocolares, instrumentos e equipa de avaliação. Devido a elevada fiabilidade inerente a
acelerometria e a medição de indicadores bioquímicos, bem como a limitações de
recursos materiais e temporais não foi realizado estudo piloto destas variáveis.
Introduction: Physical Inactivity is one of the main etiological factors of morbidity and mortality in today’s society. Physical activity is a great ally in weight management and obesity prevention, decreasing the risk of developing cardiovascular disease, diabetes, increasing cardiorespiratory fitness and the likelihood of living longer and healthier. This study aims to design and test a methodological proposal to characterize and analyze the associations of different cardio metabolic and nutritional factors with physical activity habits, considering three distinct groups (sedentary, walkers and walkers with regular and structured physical activity). Objective: In the initial phase, it was proceeded a survey and confrontation between different methodologies and quantifying tools of the studied variables, selected in a sustained manner in the literature the design of the proposed methodology. For the testing and determination of the consistency of the tools, protocol procedures and the evaluation team, the development of a pilot study in adult population (ages between 18 and 35 years) of both sexes was used. In this context, the socio-demographic data, health status in general, food intake (Block & Subar, 1992) (n=30), physical activity (Baecke, Burema & Frijters, 1982) (n=38), anthropometric measurements (Fragoso & Vieira, 2005) (n=27) and cardiorespiratory fitness (YMCA) (Golding, Myers, & Sinning, 1989) (n=23), were evaluated in the pilot study. Conclusion: The interclass (763 R≥1.000; p<.05) and Pearson (.457³ r ≥.704; p<.05) correlation coeficiente were found high, as well as reduced values of Technical Error of Measure (.028>ETM<1.982), Medium Error (-.225>‘Me error’<2.392) and Coefficient of variation (.156%>CV<6.275%), test the consistency and reliability of protocol procedures, instruments and evaluation team. Due to the high reliability inherent in the accelerometry and measurement of biochemical indicators, as well as the limitations of material and temporal resources, no pilot study of these variables was carried out.
