Summary of the research
The relationship of the entry angle to the basin with the digital level of the Javelin Throwers
The study of sports movement from a mechanical point of view is the main factor in the accurate understanding of the details of movement performance, which helps in discovering errors and their causes and work to correct them.

Therefore, the study aims to "identify the relationship of the entry angle to the basin with the digital level of the javelin contestants.

" Distinguished in the javelin throwing competition by (6) attempts for each player, and the best (3) attempts were chosen for each player, so that the total number of attempts analyzed was (9) attempts.

The results of the study showed: There is a direct and statistically significant relationship at the level of significance (α ≤ 0.05) between the numerical level and each of the kinematic variables (disposal speed, height of disposal point, and angle of entry into the basin) and the ideal angle for entering the basin in the javelin competition ranges between (27: 25) o.
