Abstract :Being overweight has serious health consequences for schoolchildren. Schools use different physical education insert ignore into journalissuearticles values(PE); programs for obesity prevention in children, but the overall positive impact of school-based interventions is questionable. This scientific work investigated the effects of high-intensity interval training insert ignore into journalissuearticles values(HIIT); intervention on physical fitness performance and body mass index insert ignore into journalissuearticles values(BMI); of overweight primary schoolchildren insert ignore into journalissuearticles values(seven years old males);. Sixty-four boys, who had overweight, participated in this study. All participants practiced 44 PE classes. Control group insert ignore into journalissuearticles values(G1; n=32; mean age: 7.46±0.32 years; mean height: 123.35±3.28 cm; mean body mass: 27.81±2.32 kg; mean BMI: 17.82±0.11); performed curriculum PE during the investigation. The experimental group insert ignore into journalissuearticles values(G2; n=32; mean age: 7.54±0.27 years; mean height: 123.26±3.41 cm; mean body mass: 27.84±2.07 kg; mean BMI: 17.78±0.14); performed sixteen-week HIIT intervention in PE classes. Participants\` height, weight, BMI, and physical fitness: push-up test, running sprint test, standing long jump test insert ignore into journalissuearticles values(SLJ);, seat-and-reach test insert ignore into journalissuearticles values(SRT);, and six-minute walk test insert ignore into journalissuearticles values(6MWT); were assessed in pre- and post-PE intervention. There were significant insert ignore into journalissuearticles values(p<0.05); differences between both groups in fitness tests and BMI values in the post- intervention period. Participants insert ignore into journalissuearticles values(G2);, who practiced HIIT intervention, demonstrated a higher value in fitness performance tests, except for SRT. Children insert ignore into journalissuearticles values(G2); demonstrated significant insert ignore into journalissuearticles values(p< 0.05); lower values of BMI in the post-intervention period. A sixteen-week HIIT intervention in PE classes is effective in increasing of fitness performance and decrease of BMI in overweight primary schoolchildren. Incorporating different HIIT in the PE curriculum could be effective part of overweight prevention in primary schoolchildren.
