Abstract:
The aim of the study was find out the relationship of take-off phase in long jump. For this study 10 long jumpers from Tamil Nadu Physical Education and Sports University, Chennai Were selected as subjects. The age of the subjects were ranged from 22 to 26 years. The study was determined to select the biomechanical variables namely take off phase, Take off time, Take off leg angle and Knee angle. The study was formulated as a random group design with 10 subjects. Each participant performed three jumping performance with maximum level that were video recorded with on camera positioned 5.63 meter away from the take-off board. Data were collected by analyzing the video recording of each jump. Data processing was performed using the KINOVEA motion analysis software. Collected data were analysed with Pearson product moment correlation technique and correlation co efficient was tested at 5% level of significance. It was concluded that there was a significant positive relationship between jumping performance and biomechanical parameter take off leg angle. And there was negative relationship between jumping performance and take off phases and take off time. It was concluded that there was no significant relationship between jumping performance and Knee angle.
