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.
Aiyoudong Children and Youth Sports Health Research Institute is the lead sponsor of 5 studies on the registry; 1 is open to participants now.

Body fat percentage (%)
Measured by Inbody, a body composition tester using bioelectrical impedance, in %.
Time frame: 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.
Time frame: 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).
Time frame: 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.
Time frame: From enrollment to the end of intervention at 12 weeks
Fat mass
Measured by Inbody, a body composition tester using bioelectrical impedance, in kg.
Time frame: From enrollment to the end of intervention at 12 weeks
Salivary testosterone
Salivary testosterone levels were measured using radioimmunoassay (RIA) and expressed in picograms per liter (pg/L).
Time frame: 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.
Time frame: 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.
Time frame: 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.
Time frame: From enrollment to the end of intervention at 12 weeks
