Investigating the Correlation Between Agility and Jump Performance Indices in Indian Contact Sports Persons: An Observational Study

Abstract

Introduction: The use of the jump as a plyometric exercise is a way to improve jump performance. Additionally, as it requires abrupt stopping, starting, and changing directions, it might enhance agility. Thus, this study aims to find out the relationship between drop jump variables and agility in contact sports. Materials and Methods: A total of 30 national-level male athletes (age=20.06±1.94 years; height=1.67±0.06 m; body weight: 58.02±8.40 kg) participated in this study. A drop jump test was performed on the Kistler force plate and agility was assessed by using the Illinois agility test along with the agility t-test. The Pearson correlation test was used to find the significant relationship between agility tests completion time and jump height from flight time, reactive strength index, average power, average force, and contact time for drop jumps. Results: The results indicate a significant moderate negative correlation between jump height from flight time and agility test time (r=-0.501 with Illinois agility test, P=0.005, and r=-0.601 with agility t-test, P=0.001). A significant weak negative correlation was observed between average power and Illinois agility test time (r=-0.477, P=0.008). Conclusion: These findings indicate that improved drop jumps will interpret better agility movements or vice versa; therefore, individuals who perform sports that require agile movement benefit from agility assessment and drop jump training.
