## 3 Results  
The summaries of the results are reported in Tables 1-4. For players competing in back-to-back games during the weekend (Tables 1 and 2), only RD was higher for the first game than the second game (F = 4.71, df = 36.24, \(p=0.03\)). For the rest of the variables, no significant differences between games were observed: RD-PD (F = 2.99, df = 8.25, \(p=0.12\)), HSR (F = 0.77, df = 21.06, \(p=0.39\)), HSR-PD (F = 0.66, df = 15.95, \(p=0.66\)), ACC (\(\chi^{2}\) = 0.99, \(p=0.32\)), ACC-PD (\(\chi^{2}\) = 0.79, \(p=0.37\)), DEC (\(\chi^{2}\) = 1.23, \(p=0.27\)), DEC-PD (\(\chi^{2}\) = 2.09, \(p=0.15\)), and Wellness (F = 1.82, df = 8.29, \(p=0.21\)). When comparing the players participating in either one or two games (Tables 3 and 4), only ACC (\(\chi^{2}\) = 6.44, \(p=0.01\)) was different, showing that the players competing in only one game during the weekend exhibited a greater number of accelerations. For the rest of the variables, no significant differences were found: RD (F = 1.85, df = 25.92, \(p=0.19\)), RD-PD (F = 0.71, df = 10.80, \(p=0.42\)), HSR (F = 2.16, df = 34.04, \(p=0.15\)), HSR-PD (F = 0.29, df = 27.26, \(p=0.59\)), ACC-PD (\(\chi^{2}\) = 0.23, \(p=0.63\)), DEC (\(\chi^{2}\) = 2.42, \(p=0.12\)), DEC-PD (\(\chi^{2}\) = 1.06, \(p=0.30\)), and wellness (F = 0.08, df = 23.15, \(p=0.78\)). As shown by the post hoc analysis, when considering the whole sample of players, either playing one game or back-to-back games, the RD was not different, but the players who played back-to-back games during the weekend performed 4.02 m\(\cdot\)min\({}^{-1}\) less in the second game (95% CI: 0.26-7.77; \(p=0.03\), d = 0.72; moderate). For the wellness data, the weekend's first game presented a higher Hooper index compared to the second game, independently of whether the players played one game or back-to-back games per weekend (1.6 arb. u. [95% CI -0.2-3.4]; \(p=0.14\), d = 1.17 moderate). \begin{table}
