Brief Summary

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.

Detailed Description

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.

Study Groups

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 .

Group Type: EXPERIMENTAL

TGfU volleyball intervention

Intervention Type: OTHER

Duration of intervention: 16 week; Duration of each session: 45 minutes; Frequency: One session per week during the third PE class;

The structure of each TGfU session had three parts:

The introduction part comprised 10 minutes of moderate-intensity warm-up activities; The main part comprised mini-volleyball and small-sided games (25-30 minutes); The last part of the session was the cool-down period (5 min).

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.

Group Type: ACTIVE_COMPARATOR

Regular physical education classes

Intervention Type: OTHER

Regular physical education classes following national physical education curriculum for second semester of seventh grade in primary school in Serbia.
