# Quantifying Sub-Elite Youth Football Weekly Training Load and Recovery Variation
## 3 Results
### Inter-Week Analysis  
Table 3 presents the descriptive statistics for mean weekly training load and recovery status for each weekly microcycle.  
The inter-week analysis presented significant differences in the TD (\(p\) = 0.022, \(\Delta\) = 620.11 m, \(d\) = 0.39). The sampled weekly microcycle showed a significant difference for the RPE and sRPE (\(p\) = 0.002, \(\Delta\) = 0.76 a.u., \(d\) = 0.35) and sRPE (\(p\) = 0.002, \(\Delta\) = 67.90 a.u., \(d\) = 0.35). The TQR score did not present significant differences in the inter-week analysis. Figure 3
