Abstract: Background: The Purpose of the study was to identify kinematical factors analysis of the take-off phase in Indian elite female long jumpers during the 62nd national interstate senior athletics championship 2023, Bhubaneswar, India. Methods: 8 female Indian national-level long jumpers Were selected as subjects from the 62nd national interstate senior athletics championship 2023, Bhubaneswar, India. The ages of the subjects were ranged from 22 to 31 years. The study was determined to select the biomechanical variables namely take-off time (compression phase and extension phase), take-off parameters (projection velocity, height of the CM and angle of projection of the CM) and knee angle of take-off leg (knee angle of the touchdown (T2) and maximum knee flexion (T3). The data was analysed using two Sony high-speed cameras, which have frequencies from 60 to 300 frames per second (f/s). The data were recorded from the sagittal plane and frontal plane. Camera-1 was placed perpendicularly at a distance of 8.20 m from the subject and at a height of 1.35 m. Camera-2 was placed perpendicularly in front of Camera-1 and was at a distance of 11 m from the subject's take-off ground and at a height of 1.35 m. Data were collected by analyzing the video recording of each jump. Data processing was performed using the Kinovea motion analysis software. Result: In this study, each long jumper maintains an individual jumping pattern in relation to timing and the different kinematic parameters.
