Effects of 10 week multicomponent exercise with different heart rate frequencies on body composition and physical fitness in overweight and obese young school-aged children
Introduction: During childhood and adolescence, obesity is an important predictor of adulthood obesity. Therefore, there should be given an important care to young population to improve the future of our society. To compare the effects of ten-week multicomponent exercise training with different exercise frequencies on body composition (BC) and physical fitness (PF) in overweight and obese young children. Material and Methods: 40 children, aged 12-15 (14.77 ± 1.49), were randomly selected and assigned to two experimental groups to train 3 times per week (EG1) or twice a week (EG2) for 10 weeks: EG1 (n=10), EG2 (n= 10) groups and a CG group (n= 20; no training program). Results: It was shown that experimental groups (EG1 and EG2) increased aerobic capacity, muscular strength and flexibility from pre- to post-training. The highest gains on muscular strength were observed in experimental group that performed twice a week; but better improvements on flexibility, body mass index (BMI) and body fat percentage (BFP) were observed in experimental group that performed 3 times per week. Conclusions: This type of exercise suggests that performing physical activities 2 or 3 times per week appears to be effective for physical fitness improvement, independently of the exercise frequency. However, to improve BMI and decrease BFP (body fat percentage) exercise frequency will be important in overweight and obese children. This could be a reliable choice to optimize physical fitness and improve well-being in overweight and obese children.info:eu-repo/semantics/acceptedVersio
