Abstract

Introduction: Physical fitness is the ability to perform daily physical work or sports activities without harming biological health, with cardiorespiratory fitness as one of the main components. Studies indicate that levels of cardiorespiratory fitness, in addition to being associated with overweight and sedentary lifestyle, also show a relationship with various indicators of lifestyle habits. It can be considered as a risk factor for some diseases. Objective: The present study aims to evaluate the cardiorespiratory fitness of children aged 9 and 10 years and relate it to their environmental and behavioral aspects. Methodology: Firstly, parents responded to a, life, pre-and-be, with questions about the child's habits. Then, the children's weight and height were evaluated and their body mass index was calculated. Lastly, the children performed the 20-m shuttle run test for assessment of cardiorespiratory fitness. For the comparison between the sexes, the Student's t test or the chi-square test was used. Regression models were applied. All analyzes adopt p < 0.05. Results: The body mass index (B=-0.37) had an inverse relationship with cardiorespiratory fitness, as well as the variable time to wake up (B=-0.94), the use of electronic games (p= 0 .07) the time in active play (p=0.023) showed significant results in the association of cardiorespiratory fitness. Boys had a greater amount with VO2max below the recommended, when compared to girls. Conclusion: According to the present study, it was observed that cardiorespiratory fitness showed a significant inverse association with BMI and that the main behavioral factors that were related to cardiorespiratory fitness were time spent in electronic games as well as time spent in active play.
