### Inflammatory and Hormonal Markers  
A significant time \(\times\) group interaction was found for myeloperoxidase (MPO) levels (F(1,68) = 1296.75, \(p\) < 0.001, \(\eta^{2}_{\text{P}}\) = 0.950), indicating a divergent pattern of change between groups (Table 4). Post hoc tests revealed a significant reduction in MPO levels in the algae-supplemented group from baseline to post-intervention (\(p\) < 0.001), whereas changes in the control group were not significant (\(p\) = 0.577). The between-group difference at post-intervention did not reach statistical significance (\(p\) = 0.181), although the trend favored the experimental group.  
Regarding cortisol, the analysis also showed a significant group \(\times\) time interaction (F(1,68) = 450.05, \(p\) < 0.001, \(\eta^{2}_{\text{P}}\) = 0.869). Post hoc comparisons confirmed a significant decrease in cortisol levels in the algae-supplemented group (\(p\) < 0.001), contrasting with a modest, non-significant increase in the control group. No significant between-group differences were observed at baseline or at post-intervention (\(p\) > 0.90).  
Finally, for the erythrocyte sedimentation rate (ESR), a significant interaction was detected (F(1,68) = 85.8, \(p\) < 0.001, \(\eta^{2}_{\text{P}}\) = 0.558). The algae-supplemented group experienced

a marked decrease (\(p\) < 0.001), while the control group exhibited a moderate increase (\(p\) < 0.001). The post-intervention comparison between groups approached significance (\(p\) = 0.125).
