Abstract

Athletic performance parameters encompass a wide range of physical, physiological, and biomechanical measures that are crucial for evaluating and optimising athletes’ capabilities. There are various intrinsic factors that can contribute to athletic skills, which subsequently impact overall performance. Thus, there is a need to explore significant intrinsic factors associated with athletic parameters, that can provide insights into the physiological mechanisms underlying performance. In this study, we examined the potential relationship of two such intrinsic factors, namely the H-reflex and the peroneal nerve conduction velocity, with athletic skills like dynamic balance and agility. Forty-five university-level athletes of all genders playing for different teams of Jamia Millia Islamia University, New Delhi, India were selected. All athletes underwent tibial H-reflex, peroneal NCV, mSEBT (for dynamic balance), and agility T-test evaluations. The Pearson correlation coefficient was calculated to evaluate the association of nerve function parameters (H-reflex and NCV) with athletic performance parameters (dynamic balance and agility). Results showed that H-reflex amplitude showed a significant negative correlation with both dynamic balance scores (Dominant Leg [DL]: r = −0.321 and P < 0.05; Non-dominant leg [NDL]: r = −0.397 and P < 0.01) and T-test scores (DL: r = −0.342; NDL: r = −0.321, P < 0.05), respectively. The peroneal NCV was significantly positively correlated with dynamic balance (DL: r = 0.438 and P < 0.01; NDL: r = 0.418 and P < 0.01) and agility scores (DL: r = 0.639 and P < 0.01; NDL: r = 0.641 and P < 0.01) in athletes. In conclusion, significant associations were found between H-reflex and Peroneal nerve conduction velocity and key athletic performance parameters like dynamic balance and agility among university athletes. This implies that neural function is closely linked with athletic skills and performance.
