The relation between bodily exercise and health with weight problems in school-aged children and youth has been extensively studied. A total of 31 observational research (24 cross-sectional, three potential cohort, 2 case-control, 1 mixed) were retrieved that met the suitable inclusion standards, as summarized in Table 9 [56–86]. Overweight and weight problems had been classified utilizing age- and gender-specific physique mass index criteria (e.g., BMI z-scores) within the majority of those observational research.
