Introduction: The integrative neuromuscular training (INT), which includes general and specific physical activities that are intentionally designed to improve both the health and physical fitness and expertise in movement, has been recognized as an innovative approach to training young people. Objective: To analyze the effect of INT in neuromuscular performance in young volleyball players. Methods: 32 subjects, 19 males (13.1 ± 0.5 years, 54.3 ± 12,8kg, 20.5 ± 4.5 kg / m2) and 13 females (13.3 ± 0.6 years, 52.6 ± 12,3kg, 20.4 ± 3.9 kg/m2), were divided into 2 groups (GINT – group submitted to INT and GC – control group) and subjected to (1) evaluate the somatic maturation according Mirwald et al, (2002).; and (2) anaerobic power test of the lower limbs. These procedures took place at 4 different times (before) and after 6 and 12 weeks of INT and after a detraining period of 8 weeks. It was used a repeated measures ANOVA and post-hoc Bonferroni test was carried out when found differences between the measures. To verify possible differences of change in percentage (D%) of Pre values in GC and GINT the Mann-Whitney U test. The correlation of Spearman was performed to verify the association between the values of the tests vertical jump and maturational levels found. It was found significant differences between Pre GINT and the 12 weeks and detraining GINT. However, there was no significant difference between groups (F = 1.80 and p = 0.19) and between the values of JUMP (F=1.99 and p=0.12). The percentage difference between the analyzed times (D%) and identified significant difference from Pre time to six weeks moments was observed (c2= -2.77, p <0.005), 12 weeks (c2=-4.36, p<0.001) and detraining (c2=-3.20, p<0.001). Among the maturational levels and the results of the Vertical Jump test, in all analyzed times there was no significant correlation in either group (CG: Pre – p = 0.11 and r=0.45, detraining – p=0.54 and r=0.19; GINT: Pre – p=0.09 and r=0.41, detraining – p=0.05 and r=0.53). Conclusion: The findings of this study indicate significant results when compared to the intervention time (Pre, 6:12 weeks – GINT x GINT). Thus, these data indicate that the INT can contribute to the neuromuscular performance even in young (12 to 14 years) practitioners of sports.
