The Correlation Between Nordic Hamstring Strength and Agility and Speed Performance in National Badminton Athletes

Abstract

The purpose of this research was to determine the connection between Nordic hamstring power, and agility and speed performance among Turkish national badminton players. The study included 11 male and 6 female national badminton players. The hamstring muscle power of the athletes was measured using the H-Bord machine. Additionally, agility performance was evaluated using the Agility T-Test, and the 10-meter sprint performance was measured using an electronic photocell. An analysis of the study findings revealed a statistically significant difference between NHTecc(a) and NHTecc(b) hamstring muscle strength, and the T-test and 10-meter sprint scores in terms of the gender variable. Furthermore, a strong negative correlation was observed between participants' NHTecc(a) and NHTecc(b) leg strength and their T-test performance. Supporting this finding, a negative correlation was also identified between NHTecc(a) and NHTecc(b) leg power and 10-meter sprint performance. In conclusion, this research analyzed the effects of Nordic hamstring strength on agility and speed performance in badminton athletes and identified a strong negative correlation between these variables. In this context, it is suggested that training programs aimed at improving eccentric muscle strength may help optimize agility and speed performance, particularly in the sport of badminton.
