### Offence Positional Phases  
Table 1 shows the mean values and standard deviations of the kinematic variables during the offence positional phases. A higher number of Accelerations and Player Load was recorded in the Modified Tournament in the offence positional phases. Although, significant differences were only observed in Sprint Meters Covered (Z = \(-\)3.78, \(p\) = 0.001) and Deceleration Meters Covered (Z = \(-\)2.39, \(p\) = 0.017). In the first case, differences were observed in the Early Group (\(p\) = 0.001), and there were tendencies to significance in the Late Group (\(p\) = 0.071). In the case of Deceleration Meters Covered, differences were observed in the Early Group (\(p\) = 0.017) but not in the Late Group (\(p\) = 0.308). The two-factor analysis of variance (2 \(\times\) 2) showed maturation level (Early Group vs. On-Time to Late Group) and tournament (FEB Tournament vs. Modified Tournament) as important factors, with repeated measures in the last factor. The interaction effect of the tournament factor due to maturation level is significant in the variables Accelerations (F1.35 = 5.58, \(p\) = 0.024, \(\eta\)2 = 0.137) and Maximum Sprint Speed (F1.35 = 5.22, \(p\) = 0.029, \(\eta\)2 = 0.130), and there are tendencies to significance in the variable Player Load (F1.35 = 4.02, \(p\) = 0.053, \(\eta\)2 = 0.103). \begin{table}

Table 1: Mean values and standard deviation of kinematics variables, according to maturity timing and tournament, during offence positional phases. Thus, increased values in the Accelerations and Player Load variables (Figures 2 and 3) were observed in the Modified Tournament. Significant differences were observed in the On-Time to Late Group (\(p=0.026\) and \(p=0.034\)). On the other hand, considering the Maximum Sprint Speed variable (Figure 4), there was a decrease in the Modified Tournament in the On-Time to Late Group and a slight increase in the Early Group. Although, significant differences were observed in the On-Time to Late Group (\(p=0.012\)).
