The researcher used the descriptive method using the method of biomechanical analysis on a sample of the young goalkeeper in the water polo.

The sample was chosen in a deliberate way, and 2 cameras were used.

GO Pro5) with a frequency of (50) frames / second, and extracting the values of the biomechanical variables by using the video camera to identify the horizontal and vertical displacement values, the horizontal and vertical velocity values of the movements of the two legs, Yeh.

The study results showed linear speed increased in the energy phase to increase the speed of the foot, The corners of the foot are small at the beginning of the energy phase, the average speed obtained in the recovery phase is lower because the knee is at maximum flexion
