Correlation between dynamic balance, lower limb muscle power, and speed performance in sprinters: a cross-sectional study

Abstract The ability to balance and generate muscle force are critical components of sprint performance. This study aimed to investigate the relationship between speed, lower limb muscle power, and dynamic balance in sprinters. A total of 75 sprinters, aged 18-30 years, from various sports academies and clubs in Belagavi, were recruited for this observational study. Dynamic balance was assessed using the Modified Star Excursion Balance Test (SEBT) and Multiple Single Leg Hop Stabilization Test (MSLHST), while muscle power was measured through the Sargent Jump Test. Speed was evaluated using the 30 m Sprint Test. Data analysis using Pearson’s correlation revealed a moderate positive correlation between speed and both dynamic balance (dominant leg r = 0.336, non-dominant leg r = 0.320) and muscle power (r = 0.32). Statistically significant correlations were observed between dynamic balance and speed (dominant leg , non-dominant leg ), and between muscle power and speed ( ). These findings suggest that improvements in dynamic balance and muscle power are associated with increased speed, highlighting their importance in sprint performance training.
