### Anthropometric Data  
The Backs were slightly older than the Wings (30.8 \(\pm\) 3.72 years vs. 26.9 \(\pm\) 4.51 years) and taller than the Wings and Pivots (1.92 \(\pm\) 0.08 m vs. 1.85 \(\pm\) 0.08 m and 1.87 \(\pm\) 0.06 m; Table 1). Age (\(\eta_{\mathrm{p}}\)\({}^{2}\) = 0.21) and BMI (\(\eta_{\mathrm{p}}\)\({}^{2}\) = 0.20) displayed relevant position effects. The effect was mainly determined by the difference between Pivots and Wings (age: \(p\) = 0.027, BMI: \(p\) = 0.010; Table 1). Regarding the anthropometric parameters in Table 2, we only found a relevant position effect for bicipital skinkofid (\(\eta_{\mathrm{p}}\)\({}^{2}\) = 0.34) based on four partial position effects, especially for Goalkeepers and Pivots. On a descriptive level, Pivots showed the highest value in 75% (three out of four) of the parameters. \begin{table}
