The effect of plyometric exercises on the explosive power level of the Coastal Army Club volleyball female players

The aim of this study is to find out the effect of the plyometric exercises on the explosive power of the sample. The sample of the study is 12 volleyball female players of the coastal army club the experimental method was used with two equated groups. The experimental group has undergone a training program with plyometric exercises, designed by the researcher, for six weeks. While the controlling group followed normal training of the club. The study concluded that there is a positive and active effect of plyometric exercises on the development of the explosive power. The ratio of improvement was (7.282%) for the designed program. While the ratio of improvement for those who applied the traditional training program of the club was (2.43%).So the positive effect on the level of the vertical jump increased and that positively reflected on development of players' level.

The Relationship of the length of the trunk and lower limb with the explosive strength of female students in the Faculty of Physical Education at Tishreen University

The study aimed to identify some of the selected anthropometric measurements and the explosive strength and the relationship between them in addition to the impact of practical program for the first semester of college on each of the explosive strength and the selected anthropometric measurements of the female students in the first year in the Faculty of Physical Education at Tishreen University. To determine that, the study was conducted on a sample of (45) students and used the descriptive approach, and collected physical measurements as well as selected vertical jump test of fortitude. The study showed the following results: The existence of a correlation between the explosive power and the length of the lower limb and, a lack of correlation between the explosive strength and the length of the trunk with the head. The researcher recommended that attention should be payed to the standards of physical measurements as criteria for admission to the terms of reference for physical education .The researcher also recommended the faculty can take advantage of the connectivity relations between measurements and physical fitness components in the development of motor skills and capabilities.
