Polymeric exercises and weights affected by the development of the maximum strength of the two legs among the second stage students in Handball female

تأثر تمرينات البلايومترك والاثقال في تطوير القوة القصوى للرجلين لدى طالبات المرحلة الثانية بكرة اليد

Abstract

Through the researcher's observation in the handball subject during the implementation of scoring skill among  the second stage  female students,  she identified there is  hesitation and weakness in the muscles of the legs compared to  students in the same stage during the implementation of the triple step due to the differences in the physical structure  among them because the skill of scoring is a quick process and linked to the implementation of a triple step quickly during Performance. The researcher tried to develop the muscular strength of the two legs for the students in two different methods in order to find which one is more appropriate using the device of  measuring platform for the muscle strength of the two legs. The research aimed to prepare polymeric exercises in developing the maximum strength of the two legs in the first experimental group and  prepare weight training exercises with the device in developing the maximum strength of the two legs in the  experimental group. The researcher followed the following procedures: The researcher used the experimental method by designing  two experimental groups to suit the nature of the research. The research community consisted of  female students in the second academic year, Department of Basic Education at the College of Physical Education / University of Sulaymaniyah for the academic year (2019-2020), by the intentional method, of (30) students distributed in two sections  .As for the research sample, it consisted of female  students from two sections  (A and B), as section (B) was selected randomly according to the draw method to represent the first experimental group, while section  (A) represented the second experimental group. For the purpose of parity, the students who participated in the exploratory experiments were excluded and their number was ( 4), the absentees (6) of them, and thus the sample became (10)  female students for the first experimental group and (10)  female students for the second experimental group. The researcher applied the two approaches to the two experimental groups by (3) training units per week for a period of (6) weeks and the time was the training units ranging between (30 to 40 to 50) minutes. The researcher concluded that  results showed that there was good improvement in two experimental groups in the post test in the maximum strength of the two legs  according to the variables (speed jump) of the two research groups. There are differences between the two posttests in ability  in favor of the first experimental group. There were differences between the two posttest  of the strength index reaction in favor of the second experimental group. There were differences between the two posttests in the contact time in favor of the second experimental group. There are differences between the two posttests of the jump height in favor of the first experimental group. There are differences between the two posttest  in flight time in favor of the first experimental group.
