Brief 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.

Outcome Measures

Primary Outcomes (5)

• 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 Outcomes (6)

• Salivary testosterone

  From enrollment to the end of intervention at 12 weeks

• Resilience

  From enrollment to the end of intervention at 12 weeks

• Self-esteem

  From enrollment to the end of intervention at 12 weeks

• Aggression

  From enrollment to the end of intervention at 12 weeks

• Eating Self-efficacy

  From enrollment to the end of intervention at 12 weeks
