RESUMO:
INTRODUCTION: Insufficient amounts of physical activity, excessive sedentary behavior, especially recreational time and insufficient sleep, are associated with a variety of physical health indicators, such as low levels of cardiorespiratory fitness and strength among school children and young people. These "movement behaviors" as they have been referred to, are collectively responsible for the entire 24-hour codependent period and should be checked together. Tremblay et al. In 2016, proposed to break with the paradigm of independence of these behaviors and analyze their interaction continuum, which gave rise to the Canadian Guidelines for the 24 Hours Movement for Children and Young People. While we understand what is recommended to stay healthy, we also need to understand how these behaviors are characterized in obese adolescents and their connection with physical fitness related to health (cardiorespiratory capacity and strength). OBJECTIVE: Define the 24-hour movement behavior and its relation to physical fitness in obese adolescents. METHODS: This was a cross-sectional pilot study that sought to characterize the 24-hour behavior in obese adolescents (age: 16.1 ± 1.5 years, fat percentage: 36.9 ± 4.9) , male, objectively measuring the levels of physical activity in moderate and vigorous intensities, total amount of daily steps, sedentary behavior and sleep through the use of acelometry (GT3X + Actigraph), to verify their relation with physical fitness related to Cheers. Dual energy X-ray absorptiometry (DXA) was used for the analysis of body composition. The peak VO2 was verified by incremental test in cycloergometer in an indirect way, the strength of lower limbs was verified through vertical jump with countermovement and the manual grip strength was measured by dynamometry. As a pilot study, the descriptive analysis of the results of the studied variables was presented in mean and standard deviation values of the 34 participants, the normality of the data distribution was verified through the z-score of asymmetry and kurtosis. adopted values equal to or greater than 1.96 standard deviations. The Pearson and Sperman correlation tests were used to examine the possible relationships between the variables of movement behavior and health-related physical fitness. RESULTS: Among the sample analyzed, 41% (n = 14) of the adolescents did not fulfill any of the recommendations of movement behavior. Furthermore, it was verified that the cardiorespiratory capacity of 23.4 (± 3.2) mL.kg-1.min-1 according to NHANES data is well below the value considered regular, 50th percentile that is 45.7 mL.kg-1.min-1 and the manual grip strength of 36.7 (± 8.7) kg is classified as regular considering the reference value of the 50th percentile of 36.5kg. Despite the percentage of adolescents who did not follow the guidelines, we still observed a direct and positive relationship between manual grip strength and moderate and vigorous physical activity (rs (34) =0.28, p=0.001) and daily total steps (rs (34) =0.15, p=0.02). CONCLUSION: The majority of obese adolescents do not follow the recommendations of the 24-hour movement guide. More than half of adolescents do not adhere to any recommendations. Sedentary behavior and moderate to vigorous intensity physical activity are the least frequent components. Physical activity independent of intensity is directly related to increased muscle strength.
