[Purpose] This study aimed to examine the effects of complex physical training on exercise and football performances in youth football players. [Methods] The subjects (n=16) were randomly assigned to either a complex physical training group (CPG, n=8) or a control group (CON, n=8). CPG was performed the complex physical training for 50 minute per day, and 2∼3 times per week, for 8 weeks. Exercise performance (health related physical fitness, skill related physical fitness, Y-balance and functional movement screen; FMS) and football performance (juggling, speed dribbling, shot passing, long kick and triple hop) were measured before and after 8 weeks complex physical training. [Results] Sit-up (p=0.002), sit and reach (p=0.040), 50-m run (p=0.031), side step (p=0.005), single-leg standing with eyes closed (p=0.040), plank (p=0.023), dominant composite score (p=0.002) and non-dominant composite score (p=0.005), deep squat (p=0.009), inline lunge (p=0.042), active straight leg-raise (p=0.015), rotary stability (p=0.049), total score(p=0.001), speed dribbling (p=0.030), dominant triple hop (p=0.001) and non-dominant triple hop (p=0.032) were statistical significant interactions between group and time. [Conclusion] Our findings indicate that complex physical training has beneficial effects on performance improvement of exercise and football in youth football players.
