### Agility Tests  
Analysis of the results of the agility tests with and without the ball obtained by the players in the experimental group during the initial and final tests are remarkable. For \begin{table}

Table 2: Statistical descriptions of 10 m and 20 m sprint tests; experimental group and control group. the Illinois agility test at the IT the result was 15.72 \(\pm\) 0.36 s. The values are homogeneous (CV = 2.27%) and the asymmetry is notable (\(\beta=-0.23\)). At the FT, the result was 15.04 \(\pm\) 0.18 s and the level of asymmetry between homogenous values (CV = 1.18%) was good (\(\beta=-0.03\)). The difference between averages is statistically significant, with a 4.52% increase, (\(p<0.0005\)). In the short dribbling test, the players of the experimental group had at the IT a result of 11.87 \(\pm\) 0.47 s. The values are homogeneous (CV = 3.94%) and have notable asymmetry (\(\beta=0.02\)). At the FT, the result was 11.30 \(\pm\) 0.55 s, with homogeneous values (CV = 4.84%) and notable asymmetry (\(\beta=-0.10\)). The increase rate in the ball agility performance of the players from the experimental group was 5.05%, which was statistically significant (\(p<0.0005\)). The players of the control group, in agility performance without the ball, had the result at the IT of 15.71 \(\pm\) 0.41 s, with homogeneous values (CV = 2.59%) and notable asymmetry (\(-0.46\)), and at the FT the result was 15.67 \(\pm\) 0.43 s; the values are homogeneous (CV = 2.75%) and have notable asymmetry (\(\beta=-0.32\)). The rate of increase in the ball-free agility performance of the control group players was 0.26%, which was statistically significant (\(p<0.025\)) (Table 3). Tests of Total Distance, High-Speed Running and Very-High-Speed Running Recorded during a Small-Sided Game  
Table 4 shows the physical parameters during 4 vs.4+GK SSG training, with eight reps of 2\({}^{\prime}\)30\({}^{\prime\prime}\), the pitch size being 40 m wide by 32 m long, with two large (official) goals. The total distance covered in the eight bouts in the first training session, which was considered the IT, was 2201.65 \(\pm\) 121.57 m, the values being homogeneous (CV = 5.52%) and having pronounced asymmetry (\(\beta=-118.00\)).
