Abstract

This study aimed to identify the effect of core and upper limb exercises using some tools on the requirements of muscular ability and the level of overhand serving performance for girls' volleyball team at Al-Aqsa University. The researcher conducted an experimental study on a sample of female students of the girls' volleyball team at Al-Aqsa University, consists of (11) players. The training period was six weeks, with three weekly trainings, in which exercises targeting the muscles of the core and the upper limb were used in the application of a skillful physical program in the manner of high-intensity interval training. To try to improve the muscular ability and the skillful Level of Overhand Serving performance by using several resistance tools, the researcher used the application on one group in both pre and post measurements, to reach the aim of the research.

The researcher used a number of prepared and pre-qualified physical and skill tests to obtain the results of the research, which were treated statistically using (mean, standard deviation, correlation coefficient, Cohen's effect size, multiple regression, and improvement rate between the pre and post measurements). Statistically significant differences between the pre and post measurements at the level of α ≥ 0.05 for the effect of core and upper limb exercises on a requirement (muscular capacity of the core, muscle capacity of the upper limb, and the level of overhand serving performance) of the girls' volleyball team at Al-Aqsa University in favor of the telemetry. Also, there was a statistically significant effect at α ≥ 0.05 between the level of muscular power for both the core and the upper limb on the one hand, and the skill of transmitting from above on the other hand.

The researcher recommended that it's very important to use exercises with tools because of their positive impact on the muscular ability of the core and the upper limb, and the application of exercises with tools for both the core and the upper limb on the junior category as well because of their active role in improving the muscle capacity needed by the basic skills of volleyball, overhand serving performance, the crushing serve and the offensive hit because they need almost the same physical characteristics.
