This research purposes were (1) explained the difference in the effect of regular strength and core strength training programs on the results of football long pass based on biomechanics, (2) explain the difference in the results of football long pass between players who have high and low eye-foot coordination based on biomechanics, (3) the effect of the interaction between the training program and eye-foot coordination on the long passes football results. This research used an experimental method with a 2 x 2 factorial design. A total of 12 football players from the Faculty of Sports, Sebelas Maret University, Surakarta, aged 19.25±0.62 years, participated in this research. Each participant underwent an eye-foot coordination test and a long football pass. Data were analyzed using two-way ANOVA with a significance level of 0.05. Based on the research results, it can be concluded as follows: (1) there is a significant difference in effect of regular strength training program and core strength training program in improving football long pass results (Fcount = 6.323, p-value = 0.036). The effect of the core strength training program is better than the regular strength training program in improving the results of long pass football. Seen from the biomechanics, the improvement of football long pass results was supported by a lower angle of knee flexion of the backswing kick leg and a greater angle of knee extension of the frontswing kick leg, a lower angle of inclination of the kicking leg and supporting leg at impact, a higher angle of inclination of the hip and shoulder during impact. Then this movement produces frontswing angular speed and acceleration, although the result is longer in the frontswing movement, but it was done with greater force, effort, and power, this produces greater momentum and impulse and faster ball. The core strength training program group produced higher energy and ball height and the ball was closer to the best target with an accuracy closer to 0.09 m. This movement ends with a smaller follow-through of hip angle, faster angular follow-through speed and deceleration, (2) there is a significant difference in effect between high-foot coordination and low-foot coordination on long pass football long pass football (Fcount = 10.452, p-value = 0.012. The improvement of long pass results in football in players who have high eye-foot coordination is better than those who have low eye-foot coordination. Seen from the biomechanics, the improvement of football long pass results is supported by a lower angle of knee flexion of the backswing leg and the angle of extension of the knee of the frontswing leg, a lower angle of inclination of the kicking leg and supporting leg during impact, a higher

angle of inclination of the hip and shoulder at the time of impact. Then this movement produces faster speed and angular acceleration in the frontswing movement, as well as greater force and power. However, the efforts made are not big so the momentum and impulse produced are smaller and the ball is also longer. With this support, players who have high eye-foot coordination produce lower energy and ball height, aiming to better control the fall of the ball, so that the fall of the ball is closer to the best target with a closer accuracy of 0.96 m. This movement, also ends with a smaller follow-through hip angle, as well as a faster angular follow-through speed and deceleration, (3) there is a significant interaction between the training program and eye-foot coordination for long pass football for long pass football (Fcount = 18.581, p-value = 0.003. Players who have high eye-foot coordination are more suitable if given a core strength training program. Players who have low eye-foot coordination are more suitable if given a regular strength training program.
