### Correlations  
The relationships between rate of perceived exertion (RPE) and enjoyment items from the PACES scale were generally low in both groups at the end of the intervention, with a correlation coefficient of (\(r_{\rm s}=-0.193\)). Specifically, in Group I, the correlation was slightly stronger at (\(r_{\rm s}=-0.256\)) while Group II showed a similar low correlation of (\(r_{\rm s}=-0.194\)). However, a significant difference was noted for half-time RPE, which had a moderate correlation of (\(r_{\rm s}=-0.359\)) (\(p\) = 0.047). This relationship suggests that as participants perceived higher levels of exertion, their enjoyment during the activity decreased.  
In Group I, there appeared to be no meaningful correlation between RPE and non-enjoyment items from the PACES scale, indicated by a coefficient near zero (\(r_{\rm s}=-0.063\)). Conversely, Group II displayed a moderate correlation of (\(r_{\rm s}=0.401\)) for the same items, as shown in Table 3. Nonetheless, none of these correlations reached statistical significance.  
The correlation between total exercise time and adverse effects was weak in both groups (\(r_{\rm s}\) = 0.295), with low to very low correlations observed for adverse effects measured 24 h and 48 h after exercise. A notable exception was the moderate statistically significant correlation between total time and adverse effects in the subsequent days, which was higher (\(r_{\rm s}=0.598\)) (\(p\) = 0.015).  
Additionally, an outcome that could be correlated with adverse effects is the RPE; RPE showed a moderate correlation with adverse effects in both groups (\(r_{\rm s}\) = 0.627) (\(p\) < 0.001), with Group I exhibiting a strong correlation (\(r_{\rm s}\) = 0.762) (\(p\) < 0.001). Moderate correlations were also noted for all adverse effects at 24 h and 48 h post-exercise, with statistical significance for both groups, except for DOMS at 48 h, which was significant only in Group II. Detailed data for these findings are available in Table 4.
