Abstract

The purpose of this study was the comparison of neural and performance adaptations to PLYOMETRIC training versus combined training.22 available young SOCCER players (age 14.28±0.82 years, weight 41.18±7.5 kg, height 154.5±9.36, body fat 7.43±2.68%) were randomly assigned to PLYOMETRIC group (plyometric and SOCCER skills training, PL) (n=8), combined group (combined PLYOMETRIC and sprint and SOCCER skills training, COM) (n=7) and control (SOCCER skills training) group (n=7) that performed 6 weeks of training (16 seasons). To assess neural adaptations surface EMG was done on vastuslateralis and vastusmedialis muscles in the static mode, pre and post training program. HOFFMANN REFLEX was also evaluated in soleus muscle at rest. At baseline and after training, performances of players were assessed with the tests: 5-meter sprint, 10-meter sprint, 20-meter sprint, agility test, counter movement jump [CMJ], and Bosco (5 seconds). Paired test and one- way ANOVA was used to identify any significant differences and P≤.05 was accepted. Both PLYOMETRIC and combined groups were associated with significant decreases in 5-meter sprint (-5.97, -3.87%), 10-meter sprint (-4.05, -2.33%), 20-meter sprint (-2.64, -1.64%), agility (-8.99, -7.5%) and significant increases in jump height for CMJ (12.95, 7.3%) and Bosco (14.08, 13.44%). Control group showed only a significant decrease in agility (- 4.72%). PL and COM groups showed significant increase in SEMG of vastuslateralis and medialis muscles (36.54, 15.06%), respectively. In three groups H-reflex did not show significant variation. However, magnitude of changes in PL and COM groups was not significant (P≥0.05). Therefore, according to these results it seems that effects of PLYOMETRIC and sprint training is similar and PL and COM training induced similar performance adaptations, which have possibly a neural origin and may be attributable to increased motor unit recruitment and/or faster firing rates, but motor reflex does not seem to play any role in these adaptations.
