الملخص EN

The current research aims to identify the effect of an educational program in terms of biomechanical indicators on learning some basic skills in volleyball for middle school students.

The research sample was chosen randomly, which included 16 middle school students, where the values of the torsion coefficient ranged between (-0.42 to 0.34) and these values are close to zero, and they are located in the moderate curve between (± 3).

The study was conducted on volleyball skills.

(Transmission from the top in front - reception from the bottom-the diagonal offensive beating) The effect of the proposed program on the biomechanical variables of the skills under study was identified and the results were as follows - There were statistically significant differences at the level of (0.05) in the (biomechanical indicators) of the skills under investigation, where the value of (t) computed in it was (5.09) and this value is greater than the value of (t) tabular at the level of (0.05) = (2.13) - The existence of statistically significant differences at the level of (0.05) in (all the skills under consideration), where the value of (t) calculated in it ranged between (12.18 to 33.04) and these values are greater than the value of (t) tabular at the level of (0.05) = (2.13) and with a level of significance less than 0.05, and the improvement rates in all skills ranged between (33.75 % to 61.88 %) in favor of the post measurement.
