Arrangement Order Effects of Neuromuscular Training on the Physical Fitness of Youth Soccer Players

Knowledge is limited regarding how neuromuscular training, conducted before and after soccer training, affects the fitness levels of youth soccer players. In this study, we aimed to analyze the effects of an eight-week neuromuscular training (NMT) program implemented before or after a soccer session on physical fitness in youth soccer players. Thirty-two youth soccer players were categorized into two groups—namely, NMT before soccer-specific training (NBS; n = 15) and NMT after soccer-specific training (NAS; n = 17). NMT comprised integrated resistance, dynamic stability, core, and plyometric training three times weekly and was conducted for 8 weeks. Before and after the exercise intervention, the counter-movement jump (CMJ) and 10 and 20 m sprint were analyzed, and the results of the T-agility test, Illinois change of direction test (ICDT), and Y-balance test were assessed for all participants. In terms of the interaction between the effects of the time of observation and group, both groups showed improvement in the results of the 10 m sprint and T-agility and Y-balance tests. Regarding the difference in the time of observation, the NBS group showed positive improvements in the results of the CMJ, 10 and 20 m sprints, and T-agility test after the exercise intervention, and the NAS group showed positive improvements in the results of the CMJ, 10 m sprint, T-agility test, and ICDT after the exercise intervention. These findings suggest that neuromuscular training has the potential to improve the 10 m sprint ability and T-agility test results of youth soccer players, regardless of the training sequence.
