The Effect of Integrative Neuromuscular Training on Enhancing Athletic Performance: A Systematic Review and Meta-Analysis.

: Integrated neuromuscular training (INT) is a multidimensional training method that integrates strength, balance, core stability, flexibility, and motor skill development. The aim of this study was to systematically evaluate the effects of INT on various physical performance indicators in athletes to provide evidence supporting the application of INT in training practices. : A systematic search was conducted in accordance with PRISMA guidelines across nine databases-including PubMed, Web of Science, EMBASE, Scopus, Cochrane Library, Ovid MEDLINE, WILEY, and Springer Nature Link-from inception to 26 March 2025 to identify randomized controlled trials (RCTs) examining the effects of INT on athletic performance. : A total of 19 randomized controlled trials were included, comprising 783 participants aged 11-25 years. The meta-analysis results indicated that INT significantly improved jump performance (SMD = 0.26, 95% CI [0.15, 0.37], < 0.001, I = 75%), sprint performance (SMD = -0.76, 95% CI [-0.93, -0.58], < 0.001, I = 76%), balance performance (SMD = 0.23, 95% CI [0.14, 0.31], < 0.001, I = 78%), and agility performance (SMD = -0.72, 95% CI [-1.23, -0.21], < 0.05, I = 74%). Sensitivity analyses revealed no substantial changes in jump, sprint, agility, or balance performance outcomes. : INT was found to significantly improve sprint, jump, balance, and agility performance in athletes. Analysis of the included training protocols suggested that improvements in each performance indicator required emphasis on specific training components. Moreover, greater improvements in sprint and balance performance were observed in female athletes compared to their male counterparts. Subgroup analysis revealed significant differences in training effects across populations, with female athletes showing superior improvements in sprint and balance performance following INT interventions. Additionally, interventions lasting fewer than eight weeks, with training sessions shorter than 30 min and frequencies of more than three times per week, were associated with more pronounced effects.
