Mechanical role of Arm Swing on Vertical Jump Performance

Abstract

Introduction: Advanced technology has allowed biomechanists to gather very accurate measurements of many of the parameters associated with human movement. In sports, vertical jump is very important factors. It is an effective exercise for building both endurance and explosive power and through the vertical jump performance the players take advantage in sports. So here, the present study was to analyze the Mechanical role of arm swing on vertical jump performance. Objective: 1. To know the mechanical role of arm swing and without arm swing on vertical jump performance of university level players of Jadavpur University, West Bengal, India. 2. To know the effect of power on arm swing and without arm swing of vertical jump performance of the university level players of Jadavpur University, West Bengal, India. 3. To find out the relationship between power and arm swing of vertical jump performance of the university level players of Jadavpur University, West Bengal, India. Methodology: 4 Volleyball (20.29±1.38 years, 179±4.54cm and 67±4.34kg), 4 Basketball (23.43±2.57years, 170.57±3.15cm and 62.13±7.58kg) and 4 High Jump (21.75±.95 years, 170.37±3.15cm and 64.75±2.21kg) university (Jadavpur university) level players were selected randomly as the subjects. Results: The result of study revealed that there were significant differences (t-4.17*) between arm swing (56.67±4.86cm) and without arm swing (43.21±4.23) vertical jump performance of high jump players and vertical jump performance of the volleyball and basketball players were found no significant difference but positive effect showed. Also the results showed that in power (ground reaction force) there were no significant differences found between arm swing and without arm swing of the university level players. There were also positive relationship found in Volleyball (r-0.61), Basketball (r- 0.89) and High jump (r- 0.84) University level players between power and arm swing vertical jump performance. Conclusion: Arm swing positively effect on the vertical jump performance for Volleyball, Basketball and High Jump players. Arm swing also positively effect on increased the power which in turn help to increased the jumping height of Volleyball, Basketball and High Jump players. It also concluded that there is positive relationship between power and with arm swing in vertical jump performance.
