Table 3: Mean \(\pm\) SD values of F–V profile variables and performance across different football player positions. thermore, an overemphasis on explosive actions without addressing underlying force deficits can limit the transferability of these gains to multidirectional or endurance-based activities, which are critical in football [21; 22]. These findings emphasize the need for specific training interventions that correct imbalances and promote integrated improvements in physical capacities. Forwards demonstrated more balanced F-V profiles compared to other positions, emphasizing the importance of integrating strength and velocity to perform rapid offensive actions (e.g., counterattacks and finishing plays). This is corroborated by evidence from studies indicating that forwards and offensive players generally exhibit velocity-dominated profiles, specifically adapted to meet the demands of high acceleration and rapid directional changes during offensive transitions [15; 18]. In fact, balanced profiles are critical for optimizing efficiency in ballistic and transitional movements, which are fundamental for this position [23; 24]. Conversely, midfielders exhibited the greatest F-V imbalances, although showing the highest P\({}_{\text{max}}\). This can be attributed to the hybrid demands of their role, requiring a combination of anaerobic endurance, strength and velocity to manage intense and multidirectional actions [6; 25]. These results highlight the importance of specific training programs for midfielders that address both the physical and tactical demands of their roles on the field [4; 6]. Defenders displayed the highest F\({}_{0}\) values, reflecting the necessity for strength in physical confrontations and aerial duels, which are common to this specific field position [14]. However, the V\({}_{0}\) demonstrated in this role was lower than that of forwards, suggesting that agility and acceleration are not as prioritized for their defensive functions [12; 14]. These findings align with the literature emphasizing the need for positional training programs tailored to meet the diverse neuromuscular demands of each role in football [4; 26]. Strength development is essential for defenders, whereas velocity and agility are more critical for forwards, underscoring the specificity of each role within the game context [6; 7]. Despite variations in F-V\({}_{\text{imb}}\), P\({}_{\text{max}}\) and V\({}_{0}\) variables, similar values were observed in jump height across competitive levels and positions. This result aligns with the existing literature suggesting that jump height is influenced by a complex interplay of factors (including force production, neuromuscular coordination and biomechanical technique) [27; 28]. The consistently high prevalence of force deficits (-76%) across both groups likely contributes to the stability of this variable, as force is a key determinant of vertical performance.
