<p>Baseline data of motivation-related variables.</p>

The results revealed a significant time × group interaction effect for perceived competence (p = .023) and future physical activity intention (p = .02). Although these interactions did not derive from statistically significant post-hoc pairwise comparisons, descriptive trends revealed a tendency toward an increase in perceived competence for both the ExMG and InMG, and a specific upward tendency for future physical activity intention only within the InMG.

No significant effects were observed for the remaining motivational regulations, which remained stable across all conditions. In conclusion, the findings delineate the specific and nuanced impacts of the two evaluated gamification profiles. While both the InMG and ExMG frameworks were associated with a descriptive tendency toward a slight improvement in students’ perceived competence compared to the CG, the InMG profile suggested a possible descriptive advantage in fostering intentions for future physical practice that requires further confirmation.</p></div>
