Therefore, there are significant differences between students who practiced a sport more frequently and those who practiced less frequently during the pandemic depending on the perceived difficulty for this specific period. Thus, we can say, with the same probability of 99%, that this association exists among the researched population, not only in the sample. Both the PHI value (0.572) and the Cramer's V value (0.286) are statistically significant for \(p<0.01\) and indicate an association between the two variables. The hypothesis was confirmed by the results obtained, which show that students who participate in sports activities with a high frequency are those who consider that playing sports during the pandemic was very easy; more precisely, they do sports 3-5 times a week (55.9%), while students who stated that practicing sports during this period was very difficult rarely participate in such activities, with only 3.9% of them doing sports 3-5 times a week. An interesting fact is that almost a third of those who said that it was very difficult to play sports during the pandemic do sports once or twice a week. A high percentage play sports only once or twice a week, even if it was easy (40%) or very easy (34.9%) for them to do so during a pandemic. In fact, among students who reported doing sports only once or twice a week, the difficulties due to this period did not seem to influence the frequency with which they chose to do so (Figure 1). \begin{table}

Table 3: Cont. Only three predictors proved to be more important in terms of the frequency with which students practiced physical activities and sports during the pandemic. Thus, those who practiced sports regularly during the pandemic were almost twice as likely to be boys, because exp (b) = 1.759, almost three times more likely to be students who did not consider that it is more difficult to do sports during the pandemic, because exp (b) = 2.843, and almost twice as likely to be among the students who gave more importance to the practice of sports activities during the pandemic, because exp (b) = 2.350. The adequacy of the logistic regression model is acceptable (Nagelkerke R Square = 0.226), as shown in Table 4. \begin{table}
