This study aims to assess several morphofunctional parameters in female teenagers with and without intellectual disability to characterise normality and its disturbances. More precisely, the purpose was to examine the factors contributing to the differences in body composition elements between groups, such as the physical activity level. To evaluate these parameters, we used bioelectrical impedance analysis technology (BIA), most commonly used in studies concerning body composition because it is non-invasive, quick, with high data fidelity; it can be easily moved to various locations and applied straightforwardly among populations with diverse types of intellectual disability. Our research sample comprised 212 subjects (boys and girls) aged 17.1±0.6, divided into six groups by gender and type of intellectual disability. The study found influences of physical activity level on body composition components. In addition, we report a highly significant relationship for p<0.05, body mass index and the independent variable (No. of min./week) in some groups.

The aim of this study is to evaluate the sprint speed of junior female rugby 7`s players over different distances, both with and without the ball. We hypothesize that there are statistically significant differences between the results obtained in speed tests with the ball and without it. Also, we assume that there are differences between the sprint speed of the players depending on their position. In this sense, we evaluated 22 junior female rugby 7`s players, with an average age of 15,40 ± 1,33 years (165,50 ± 5,69 cm, 63,07 ± 9,94 kg, 18,44 ± 6,31 kg fat mass, 42,34 ± 4,48 kg muscle mass, 25,26 ± 2,67 kg skeletal muscle mass), all participants in the Romanian National Women's Rugby Sevens Championship. The sprint speed was measured using the Witty Sem automated timing system, with sensor gates placed at 10, 20, and 40 meters. Each player covered the 40-meter distance four times, twice with the ball and twice without it, recording the best times achieved. The results of the statistical analysis highlight significant differences in sprint speed with and without the ball (p<0.05), as well as between the 0-20 m and 20-40 m distances, both with and without the ball (p=0.000). The results confirm the fact that there are statistically significant differences between forwards and backs in terms of the sprint speed of the athletes (p<0,05).
