Objective This study aimed to investigate the correlation of weight status in children and adolescents with their physical fitness. Methods Through random cluster sampling, students from 8 primary and secondary schools aged 6 to 13 years in Jining were selected as low weight (BMI SDS <2.0), normal weight (2.0 BMI SDS <1.0) (<2.0), overweight (1.0 BMI SDS <2.0) and obesity (BMI SDS 2.0). 50m running, physical flexibility, abdominal muscle endurance, overall endurance / coordination were evaluated by sitting body forward flexion, 1min sit-up, and the relationship between weight status and physical fitness indicators were analyzed. Results The incidence of obesity in boys and girls was 11.55% and 10.70%, respectively, without significant difference; By comparison of obese groups with different weight status, the average scores of lower extremity explosive strength, abdominal muscle endurance, overall endurance / coordination were lower than the normal weight group; univariate analysis showed that the physical performance of lower extremity explosive strength, abdominal muscle endurance, overall endurance / coordination and other were significantly negatively correlated with BMI SDS (P-value <0.05), but still grouped by different gender (P-value <0.05). Conclusion The physical performance of children and adolescents with normal weight group was better than that in the obese group, in which lower limb explosive force, abdominal muscle endurance, overall endurance / coordination were significantly negatively correlated with weight status, and there was no significant difference between genders, while overweight and obesity had no significant effect on physical flexibility.
