Applied Research on the Impact of a Neuromotor Development Program on the Lower Limb Strength of Young Junior Athletes in Greco-Roman Wrestling

This study aims to investigate the impact of a structured and specific motor intervention program on the development of lower limb strength in young junior athletes practising Greco-Roman wrestling. Given the importance of explosive strength in executing techniques and decisive actions during combat, this research adds value by implementing a progressive applied protocol adapted to the neuromotor development level of children aged 10 to 12 years. The study was conducted over 17 months and involved two groups of athletes (experimental and control), each comprising 14 registered wrestlers from School Sports Club No. 5 in Bucharest. The experimental group followed a complementary motor training program focused on plyometric exercises, body-weight strength applications, and specific wrestling exercises, while the control group followed the standard training regimen. The intervention's impact was assessed using the OptoJump Next system, a biomechanical analysis tool that measured key explosive strength parameters: jump height, ground contact time, flight time, and reactive strength index (RSI). The applied tests included the counter-movement jump (CMJ). Comparative analysis of initial and final tests revealed a significant improvement in neuromotor performance among athletes in the experimental group, confirming the effectiveness of the proposed methodology. Thus, this research offers a reproducible intervention model, based on objective evidence, with direct applicability in training young Greco-Roman wrestlers.
