Not Applicable

Completed

• Conditions: Prevention
• Interventions: Behavioral: Exercise and dietary calorie restriction

• Registration Number: NCT06524908
• Lead Sponsor: Aiyoudong Children and Youth Sports Health Research Institute

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.

Arm && Interventions

Group	Intervention	Description
Exercise and dietary calorie restriction intervention group	Exercise and dietary calorie restriction	Received a twelve-week comprehensive intervention. The number of participants is 50.

Primary Outcome Measures

Name	Time	Method
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 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.
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.

Secondary Outcome Measures

Name	Time	Method
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).
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.
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.
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.
