简要总结
The goal of this study is to find out if doing a 16-week volleyball program integrated in physical education classes at school can make primary school students stronger, faster, and have better endurance. The study also wants to see whether the program can lead to changes in the students' body weight, body fat, and muscle mass.
详细描述
Eighty-eight healthy primary school students (mean age 13.3 years) were randomized to a TGfU volleyball intervention group (VG) or a control group (CG). CG participants attended three regular physical education (PE) classes per week, while VG participants attended two regular PE classes and a TGfU volleyball intervention that was implemented in the third PE class. The main part of each volleyball intervention session was based on the "Teaching Games for Understanding" (TGfU) model. This approach emphasizes the development of fundamental skills and tactical understanding of the game by utilizing modified games, such as small-sided games and mini-volleyball. By using this method, participants are able to increase their interaction with the ball and engage in moderate-to-vigorous gameplay intensity more frequently. The primary study outcomes were assessed before and after the 16-week intervention for both VG and CG participants. The main hypothesis is that implementation of the TGfU volleyball intervention in the physical education curriculum will lead to greater improvement in body composition and physical fitness outcomes among seventh-grade primary school students compared to those who receive traditional physical education classes, demonstrating that this intervention can be an effective method for reducing adiposity and promoting physical fitness levels among adolescents.

研究组 & 干预措施
TGfU volleyball intervention
According to the national curriculum, children in Serbia must attend three regular physical education (PE) classes per week.
Besides attending two regular PE classes, participants in the experimental group also followed a 16-week TGfU volleyball intervention that was implemented during the third PE class. The total number of sessions: 32 regular PE + 16 TGfU volleyball intervention .
干预措施: TGfU volleyball intervention (Other)
Control group
Control group (CG) participants followed the national physical education curriculum. The CG participants conducted three regular PE classes per week or 48 regular PE classes in total.
干预措施: Regular physical education classes (Other)
结局指标
主要结局
Change in Cardiorespiratory Fitness
时间窗: Baseline, after 16 weeks
Cardiorespiratory fitness is considered one of the most powerful health-related markers in adolescents. In this study, cardiorespiratory fitness is assessed using the 20-m shuttle-run test, which was adopted from the Eurofit test battery. Scoring is obtained as VO2max values (mL/kg/min).
次要结局
- Change in Sum of skinfolds(Baseline, after 16 weeks)
- Change in Strength(Baseline, after 16 weeks)
- Change in Body Weight(Baseline, after 16 weeks)
- Change in Muscle Mass Percentage(Baseline, after 16 weeks)
- Change in Agility(Baseline, after 16 weeks)
- Change in Flexibility(Baseline, after 16 weeks)
- Change in Speed(Baseline, after 16 weeks)
- Change in BMI(Baseline, after 16 weeks)
- Change in Body Fat Percentage(Baseline, after 16 weeks)
