The study aimed to identify the efficiency of the motor response speed in predicting the performance of some basic skills of young handball goalkeepers, to identify the percentage of the contribution of motor response speed to the performance of some basic skills of young handball goalkeepers, while the research sample was represented by handball goalkeepers for young people in Iraq. Their choice was by the intentional method, and the mean, standard deviation, simple correlation coefficient, multiple regression coefficient by all regression method, and regression coefficient by gradient regression method will represent the statistical means to reach the results represented in the handball goalkeepers owning a kinetic response speed And the extent of its contribution to the performance of some basic skills for them, as predictive equations were reached, especially through the contribution of mindfulness to the performance of some of the selected basic skills, which are as follows:

The prediction equation in the performance of the blocking skill from the right corner of the goal area with the arms to the upper corner of goal No (2).

The prediction equation in the performance of the blocking skill from the left corner area of the goal with the arms to the upper corner of goal No (3).

The prediction equation in the performance of the blocking skill from the right forearm area by jumping to the side with the arms to the upper right side of goalkeeper No (4).

The prediction equation in the performance of the blocking skill from the left forearm area by jumping to the side with the arms to the upper right side of goalkeeper No (5).

The researcher recommended that trainers should focus on paying attention to training programs that develop the speed of motor response of handball goalkeepers because they have an effective role in their skill performance.
