Objectives:

the aims of the study were to provide gender- and age-specific physical fitness levels among Serbian schoolchildren and to identify prevalence of overweight and obesity.

Methods:

a sample of 6,188 boys and 6,023 girls aged nine to 14 years were assessed using the physical fitness battery established through the National Fitness Project of Serbia. Physical fitness levels were determined for body height, body weight and body mass index and for six physical fitness tests (sit and reach, 4 x 10 m shuttle run, standing long jump, 30 sec sit-ups, bent arm hang, 20-m shuttle run). Centile smoothed curves for the 5rd, 25th, 50th, 75th and 95th percentiles were calculated using Cole's LMS method. Prevalence of overweight and obesity was identified applying cut-off points for children (International Obesity Task Force).

Results:

the results revealed that anthropometric measures were higher in boys than in girls. In addition, boys had better physical fitness levels for all tests except for the sit and reach test, where girls performed slightly better. The overall prevalence of overweight and obesity amounts to 24.8% (19.8% overweight and 5% obese). With respect to gender, the prevalence of overweight and obesity was higher in boys (27%) compared to girls (22.4%).

Conclusion:

the presented data are the most up-to-date gender- and age-specific physical fitness levels for Serbian schoolchildren aged 9-14 years. The findings regarding prevalence in overweight and obesity indicated an alarming trend when compared to similar data from other similar studies (in European countries).
