### Effect of Pre-Season Training on Lower Body Part Strength  
Pre-season training favorably affected the maximum strength of quadriceps [(Team 1: 3.65 \(\pm\) 2.41, \(p\) = 0.002), (Team 2: 3.06 \(\pm\) 2.35, \(p\) = 0.003) and (Team 3: 2.95 \(\pm\) 2.09, \(p\) = 0.003)] and hamstrings [(Team 1: 2.83 \(\pm\) 1.56, \(p\) \(<\) 0.001), (Team 2: 2.08 \(\pm\) 1.88, \(p\) = 0.007), (Team 3: 1.76 \(\pm\) 1.03, \(p\) \(<\) 0.001)] for every team that participated in the current study, with not subsequent differences between the teams (Table 7).
