Summary:
The students were divided into an intervention group and a control group. The intervention group attended fat loss exercise classes three times a week and the parents cooperated with us in dietary monitoring and control. Before and after the intervention, questionnaires were completed, physical fitness and body composition were measured, and physical activity measurement bracelets were worn for 4 days. In this study, it is possible to know the mental health state, physical activity habits, body composition and physical fitness of adolescents.

Primary Outcome Measures: Body fat percentage (%), Measured by Inbody, a body composition tester using bioelectrical impedance, in %., From enrollment to the end of intervention at 12 weeks|Physical fitness, Measured using China National Standards for Students' Physical Health (2014 revision), with a minimum value of 0 and a maximum value of 100, higher scores respond to better fitness., From enrollment to the end of intervention at 12 weeks|Physical activity, Physical activity (PA) was measured using Actigraph GT3X+ accelerometers, with data expressed as minutes per day (min/day)., From enrollment to the end of intervention at 12 weeks|Fat-free mass, Measured by Inbody, a body composition tester using bioelectrical impedance, in kg., From enrollment to the end of intervention at 12 weeks|Fat mass, Measured by Inbody, a body composition tester using bioelectrical impedance, in kg., From enrollment to the end of intervention at 12 weeks
Secondary Outcome Measures: Salivary testosterone, Salivary testosterone levels were measured using radioimmunoassay (RIA) and expressed in picograms per liter (pg/L)., From enrollment to the end of intervention at 12 weeks|Resilience, Connor-Davidson Resilience Scale-10 (CD-RISC-10). The scale consists of 10 items, each of which has a score range of 0-4, and the total score range of the scale is 0-40, with higher scores representing greater resilience., From enrollment to the end of intervention at 12 weeks|Self-esteem, The Rosenberg Self-Esteem Scale was used, with a total of 10 items.

The higher the score, the more aggressive the individual is in that area and the worse the outcome., From enrollment to the end of intervention at 12 weeks|Eating Self-efficacy, Eating Self-Efficacy Scale .

The minimum score is 10 and the maximum score is 100. Higher scores indicate greater self-efficacy in eating and better outcomes., From enrollment to the end of intervention at 12 weeks|Exercise Self-Efficacy, Exercise Self-Efficacy Scale . The minimum score is 18 and the maximum score is 180. The higher the score, the stronger the self-efficacy in exercise and the better the result., From enrollment to the end of intervention at 12 weeks
