Table 1 presents the descriptive data of the participants. A total of 227 students (age: 9.92 \(\pm\) 1.33 years) participated in the present study. The participant sample was nearly homogeneous, with 52.42% boys and 47.68% girls. The sample was evenly distributed across the five grade levels, with each grade representing no more than 25% of the total sample. The mean BMI was 18.44 \(\pm\) 3.31 kg/m\({}^{2}\), and over 60% of the participants engaged in physical activity outside of school. In the jump tests performed by the participants, specifically in the vertical jump test, the mean distance was 134.94 \(\pm\) 24.78 cm, and in the CMJ test, it was 19.66 \(\pm\) 4.15 cm. Additionally, grip strength showed a mean of 16.44 \(\pm\) 4.16 kg among participants, and the mean \begin{table}

Table 1: Descriptive socio-demographics, anthropological measures, and physical/cognitive test results. number of repetitions performed in the 30-s abdominal test was 17.45 \(\pm\) 4.74. It is worth noting that there were no significant differences between genders in the functional tests. Regarding the control of dependent variables related to cognitive performance, the mean response times for correct answers were found to be 21.41 \(\pm\) 10.04 in the Stroop Test, with differences observed according to gender. Significant differences were found between boys (6.38 \(\pm\) 6.01) and girls (7.81 \(\pm\) 6.54) in the number of correct responses given during the Stroop Test. Significant differences between both sexes were also found in the parameter of fastest correct response in the Stroop Test, with a value of 25.76 \(\pm\) 147.17 for boys and 13.10 \(\pm\) 8.79 for girls. The parameters of average response time and average correct response time were similar for both sexes, with a mean value of 21.31 \(\pm\) 10.04 for average response time and 17.54 \(\pm\) 8.82 for average correct response time. Principio del formulario. Regarding memory, which was assessed through the word recall test, females showed a better performance compared to males (6.52 \(\pm\) 1.56 vs. 5.73 \(\pm\) 1.51) in terms of the number of words recalled. The bivariate analysis (Table 2) revealed that none of the dependent variables related to cognitive status were correlated with engaging in sports outside of school, nor with any of the functional jump tests, specifically horizontal jump or vertical jump.
