### Academic Performance  
For both academic parameters, significant differences between groups were observed, and the non-obese athletes showed superior performance than obese subjects (as illustrated in Table 3). The largest group difference was observed in mathematics (\(p\) < 0.001; \(\eta_{\rm p}\)\({}^{2}\) = 0.367), comparable with science (\(p\) = 0.013; \(\eta_{\rm p}\)\({}^{2}\) = 0.195). The association between mathematics and science was r = 0.547.
