... ioimpedance was used to measure body composition. The students' ages ranged from 18 to 25 years, with an average of 21 ± 1.5 years. Their average weight was 66.3 ± 7.9 kg, and their average body mass index was 23.2 ± 2.16 weight kg/height 2 . The results showed a prevalence of 19.3% (n = 26) overweight (BMI ≥ 25) in the sample; 80.1% (n = 109) of the participants were of normal weight, according to WHO criteria. The Body Mass Index (BMI) was similar in students from the three training schools (ESMIC 23.65 ± 2.3 kg/m 2 ; EMSUB 23.41 ± 2.4 kg/m 2 ; and ESPRO 22.57 ± 1.4 kg/m 2 ). The absolute value of fat mass in the ESPRO students showed lower weight in fat than the
