In this thesis, the kinematic indicators of success in the athletic discipline of long jump will be described and analyzed. The data were collected from competitions held in 2022 and 2023, focusing on elite long jumps that meet the criterion of scores higher than 1000 points according to the World Athletics (WA) tables. The diagnostic equipment used for data collection includes the OptoJump system and a laser for measuring movement speed (muscleLab laser). From the collected data, a comparison of several indicators was made, leading to conclusions about which kinematic indicators enable long jumpers to perform at the highest level. This same data can be used for further analysis and as potential information for selecting elite long jumpers. The results indicate a positive relationship between a lower percentage of speed deceleration during the run-up and the take-off phase. In other words, minimizing the loss of horizontal speed in the run-up while maximizing vertical speed at the end of the take-off is crucial for the final result. A similar comparison will be made regarding step length and the duration of foot contact with the ground during the run-up and take-off, which could indicate the same conclusions.
