### Group That Practices PE  
Table 10 shows the results referring to the means, SDs, amplitudes, and 95% CIs for the different dimensions of the Mental Health Inventory for the group that practices PE. The last dimension, corresponding to the total of the previous dimensions, presented a mean score of 152.37 (\(\pm\)30.59), with a CI between 82 and 215. In Table 11, the correlations between the Mental Health Inventory variables, together with age, BMI, and the mean practice time of PE per session (in minutes), are shown. Finally, Table 11 shows that the age variable established two significant positive correlations, namely a small one with the BMI variable (\(r\) = 0.134, \(p\) < 0.05) and a strong one with psychological well-being (\(r\) = 0.783, \(p\) < 0.01). No significant correlations were found for the BMI and mean practice time variables. The minutes per week were not associated with any of the variables studied except for the mean practice time (\(r\) = 0.337, \(p\) < 0.01). \begin{table}
