## 3 Results  
Descriptive statistics of intra-week variations of sleep and training demand outcomes can be found in Table 3. Repeated measures ANOVA revealed significant within-week variations in sleep duration (\(p=0.043\); \(\eta_{p}^{2}=0.148\)), quality of sleep (\(p=0.035\); \(\eta_{p}^{2}=0.139\)), RPE (\(p=0.007\); \(\eta_{p}^{2}=0.306\)), session-RPE (\(p=0.011\); \(\eta_{p}^{2}=0.309\)), HRmin (\(p=  
\(\eta_{p}^{2}=0.490\)), distance covered at Z3 (\(p<0.001\); \(\eta_{p}^{2}=0.606\)), distance covered at Z4 (\(p<0.001\); \(\eta_{p}^{2}=0.552\)) and distance covered at Z5 (\(p<0.001\); \(\eta_{p}^{2}=0.537\)). However, no significant intra-week differences in the time to fall asleep (\(p=0.267\); \(\eta_{p}^{2}=0.382\)), rested feeling (\(p=0.093\); \(\eta_{p}^{2}=0.109\)), session duration (\(p=0.050\); \(\eta_{p}^{2}=0.247\)), HR average (\(p=0.088\); \(\eta_{p}^{2}=0.189\)), nor peak speed (\(p=0.137\); \(\eta_{p}^{2}=0.143\)) were found. Pairwise comparisons revealed that, on MD-2, the sleep duration was significantly longer than on MD-4 (\(+0.5\) h; \(p=0.013\)) and MD-5 (\(+1\) h; \(p<0.01\)). MD-2 was significantly more intense regarding RPE than MD (\(+1.3\) A.U. ; \(p=0.035\)), while MD-4 was more intense in RPE than MD-5 (\(+0.6\) A.U. ; \(p=0.031\)). The MD-5 had significantly lower session-RPE than MD-2 (\(-95.2\) A.U. ; \(p<0.001\)), MD-3 (\(-124.0\) A.U. ; \(p<0.001\)) and MD-4 (\(-93.7\) A.U. ; \(p<0.001\)). The MD-4 had significantly greater minimum HR than MD (\(+27\) bpm; \(p=0.049\)) and MD-3 (\(+21.6\) bpm; \(p=0.030\)). The HRpeak was significantly higher in MD-3 than in MD (\(+52.4\) bpm; \(p=0.049\)). Significantly less total distance was covered on MD-4 in comparison to MD (\(-3635.3\) m; \(p=0.001\)), MD-2 (\(-1363.3\) m; \(p=0.043\)), and MD-3 (\(-2225.3\) m; \(p<0.001\)). Moreover, significantly less total distance was covered on MD-5 in comparison to MD (\(-3317.7\) m; \(p=0.006\)) and MD-3 (\(-1908.0\) m; \(p<0.001\)). The pace (meters covered per minute) was significantly higher in MD-3 than in MD (\(+26\) m/min; \(p=0.025\)) and MD-4 (\(+27.3\) m/min; \(p<0.001\)). Distance covered at Z1 was significantly lower in MD-4 than in MD (\(-1196.9\) m; \(p=0.002\)), MD-2 (\(-705.5\) m; \(p<0.001\)) and MD-3 (\(-976.9\) m; \(p<0.001\)). Similarly, distance covered at Z1 was significantly lower in MD-5 than in MD (\(-914.1\) m; \(p=0.045\)), MD-2 (\(-422.7\) m; \(p=0.040\)) and MD-3 (\(-694.1\) m; \(p<0.001\)). The distance covered at Z2 was significantly lower in MD-4 than in MD (\(-800.5\) m; \(p=0.002\)), MD-2 (\(-350.3\) m; \(p<0.001\))
