摘要：The article compares the intensity of physical activity during recess in second and third grade schoolchildren according to gender and body fat percentage. Sixty-three second- and third-graders, classified with normal or high fat percentage, evaluated by bioelectric impedance (Inbody 720) participated in the study. During 27 periods of 30 minutes of recess, physical activity intensity and heart rate were evaluated with ActiGraph-GT9X accelerometers, the system for observing fitness instruction time (SOFIT) was used to measure the moderate-to-vigorous physical activity index and the energy expenditure, perceived exertion was determined using the Pictorial Children's Effort Rating Table (PCERT). The analysis of variance (ANOVA) 2x2 showed significant differences between measurements according to the percentage of normal fat compared to high, for moderate physical activity (boys: 0.003, girls: 0.005), caloric expenditure (boys: 0.005, girls: 0.005), METS (boys: 0.003, girls: 0.001), and heart rate (boys: 0.005, girls: 0.005). Due to the increased risk of diseases associated with a sedentary lifestyle, it is important to implement strategies during recess that involve more students with greater adiposity in physical activity.
