This study evaluated the mechanical determinants of 30 m sprint performance in 110 amateur soccer players and identified variables of sprint, slalom, and kick tests. Associations were identified using Pearson's correlation coefficient. A p-value of 0.0007 was considered statistically significant for all analyses after performing Bonferroni correction adjustment. Relative peak running power (P-max) was significantly correlated (p<0.0007, r=-0.875 to -0.984) with sprint split times across all distances (5-30 m). Relative theoretical maximum horizontal force (F-0) significantly correlated with acceleration performance (0-15 m, p<0.0007, r=-0.756 to -0.951). Average ratio of forces for the first 10-m (RF_10m) was significantly correlated (p<0.0007, r=-0.909 to -0.965) with sprint split times across 20-30 m and gap time at 10-20 m and 20-30 m. Maximal value of ratio of force (RFmax) was significantly correlated (p<0.0007, r=-0.718 to -0.959) with sprint split times across 5-25 m. Theoretical maximum velocity (V-0) was significantly correlated , (p<0.0007, r=-0.540 to -0.684) with sprint times across 20-30 m, and gap time 10-20 m and 20-30 m (p<0.0007, r=-0.880 to -0.915). These results indicate emphasis should be placed on training protocols that improve relative peak running power (P-max), particularly in time-constrained environments such as team sports, focusing on maximal force production or maximal running velocity ability. Furthermore, attention should be paid to the technical component of the received force in the horizontal direction to the monitor training adjustments and further individualize training interventions.
