Conditions
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.
Interventions
BEHAVIORALExercise and dietary calorie restriction
The intervention group received an exercise intervention three times a week (resistance exercise from 4:30-5:00 p.m. and aerobic exercise from 5:00-5:30 p.m.), and a caloric restriction intervention (guided semi-libre diet with caloric intake restricted to 75% of overall consumption, with parents keeping track of calories and food groups and receiving regular check-ups)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Body fat percentage (%) | From enrollment to the end of intervention at 12 weeks | Measured by Inbody, a body composition tester using bioelectrical impedance, in %. |
| Physical fitness | From enrollment to the end of intervention at 12 weeks | 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. |
| Physical activity | From enrollment to the end of intervention at 12 weeks | Physical activity (PA) was measured using Actigraph GT3X+ accelerometers, with data expressed as minutes per day (min/day). |
| Fat-free mass | From enrollment to the end of intervention at 12 weeks | Measured by Inbody, a body composition tester using bioelectrical impedance, in kg. |
| Fat mass | From enrollment to the end of intervention at 12 weeks | Measured by Inbody, a body composition tester using bioelectrical impedance, in kg. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Salivary testosterone | From enrollment to the end of intervention at 12 weeks | Salivary testosterone levels were measured using radioimmunoassay (RIA) and expressed in picograms per liter (pg/L). |
| Exercise Self-Efficacy | From enrollment to the end of intervention at 12 weeks | 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. |
| Resilience | From enrollment to the end of intervention at 12 weeks | 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. |
| Self-esteem | From enrollment to the end of intervention at 12 weeks | The Rosenberg Self-Esteem Scale was used, with a total of 10 items. Scores on the scale range from 10 to 40, with higher scores indicating higher levels of self-esteem and better outcomes. |
| Aggression | From enrollment to the end of intervention at 12 weeks | Assessed using the Buss-Perry Aggression Questionnaire with a total score range of 29-145. The higher the score, the more aggressive the individual is in that area and the worse the outcome. |
| Eating Self-efficacy | From enrollment to the end of intervention at 12 weeks | 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. |
