3.1. Sample Characteristics
injuries, fractures, fat-free mass
A total of 402 students completed all the parts of the study and were analyzed. Of these, 196 were girls (48.76%) aged 15.83 ± 1.7 years, and 206 were boys (51.24%) aged 15.87 ± 1.69 years. Referring to the sex-specific BMI-for-age percentile charts, the overall prevalence of overweight and obesity in boys was 11.7% and 29.1% and in girls 8.7% and 15.3%, respectively. Significant differences were noted in weight, height, BMI, PBF, and fat-free mass (Of the 402 individuals surveyed, 184 participants (45.77%; 118 males and 66 females) reported having suffered PA-related injuries in the past year, of which 93 subjects (55 males and 38 females) suffered one injury, 54 subjects (41 males and 13 females) suffered two injuries, and 37 subjects (22 males and 15 females) suffered three or more PA-related injuries. Bruises (29 cases) and strains (27 cases) were the most common types of PA-related injuries among male students; conversely, bruises (16 cases) and fractures (10 cases) were the most prevalent PA-related injuries among female students. Fifty-nine participants (36 males and 23 females) reported experiencing two or more types of PA-related injuries. The limbs were the most injured parts of the body in boys (18 cases for upper limbs and 79 cases for lower limbs), while the head and lower limbs were the most vulnerable parts in girls (respectively, 12 and 34 cases). Of all the injuries that occurred, only 43 cases (33 boys and 10 girls) required urgent medical intervention.
