One of the skills that should be possessed by block players in volleyball is reaction speed. It effectively influences the player’s ability to block strong shots from the opponent correctly. However, response time is influenced by how much the player benefits from the prime which is provided around him to prepare for the next movement. When a player effectively prepares for the required movement in advance, these information are processed more rapidly, and thus, we notice an improvement in the player’s reaction time. Thus, we have conducted this study to find out the effect of special exercises designed for motor preparation on reaction speed for block players center (3) in volleyball . For the current study, we have used the priming test, suggested by Rosenbaum and Kormblum (1982) as a prior test and a follow-up test for both test group and blocked group, in order to figure out the effect of providing primes on the player’s reaction time. The primes provided were either identity for the required movementor neutral. We have followed the method of calculating the number of correct attempts executed by the players, in order to infer the change in their reaction speed. The results revealed improvement in the number of correct attempts for test group after applying the suggested training program in the two situations (identity-neutral). Therefore, we find that the applied program has contributed to an increase in the number of correct executed attempts, which suggests an increase in the speed of processing the information, leading to enhancing the reaction speed in block players center (3). In light of these findings, we have recommended the necessity of using the suggested training program as part of the training plans provided for Syrian volleyball teams. This recommendation is due to the program’s importance in improving reaction speed, on which most offensive and defensive skills in this game depends. We have also recommended the necessity of conducting further research and study, based on modern training methods.

Research summary
تتناول هذه الدراسة تأثير التحضير الحركي على سرعة رد الفعل لدى لاعبي حائط الصد مركز (3) في الكرة الطائرة. تُعد سرعة رد الفعل من الصفات الأساسية التي يجب أن يتمتع بها لاعب حائط الصد، حيث تساهم بشكل فعال في قدرته على صد الضربات الساحقة للمهاجمين. تعتمد سرعة رد الفعل على مدى استفادة اللاعب من المعلومات الأولية المتوفرة في محيطه للتحضير للحركة القادمة. استخدمت الدراسة اختبار ال Priming المقترح من قبل العالمين Rosenbaum و Kornblum، حيث تم تقديم معلومات مسبقة للاعبين إما مطابقة للحركة المطلوبة أو حيادية، وتم قياس عدد المحاولات الصحيحة كدليل على سرعة رد الفعل. أظهرت النتائج تحسنًا في عدد المحاولات الصحيحة للمجموعة التجريبية بعد تطبيق البرنامج التدريبي المقترح، مما يدل على زيادة سرعة معالجة المعلومات وتطوير سرعة رد الفعل. بناءً على هذه النتائج، أوصت الدراسة بضرورة استخدام البرنامج التدريبي المقترح ضمن الخطط التدريبية لفرق الكرة الطائرة السورية، وكذلك إجراء المزيد من البحوث والدراسات التي تعتمد على الوسائل التدريبية الحديثة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة في مجال تحسين أداء لاعبي الكرة الطائرة، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، حجم العينة كان محدودًا (12 لاعبًا فقط)، مما قد يؤثر على تعميم النتائج. ثانياً، لم يتم استخدام أدوات قياس زمن رد الفعل بشكل مباشر، بل تم الاعتماد على عدد المحاولات الصحيحة، وهو ما قد لا يعكس بدقة سرعة رد الفعل. ثالثاً، كان من الأفضل تضمين مجموعة متنوعة من التمارين الحركية لتقييم تأثيرات مختلفة على سرعة رد الفعل. وأخيراً، كان من الممكن تقديم تحليل أكثر تفصيلاً للبيانات الإحصائية لتعزيز قوة النتائج والاستنتاجات.

This research is carried out on a sample of 8 players who are setters selected from the Syrian ladies teams. The researcher used the experiential method because it suits the nature of the research, and divided the sample into two groups: experimental and control group. The researcher carried out a pre-test on the two groups. Then the experimental program was put into practice for 8 weeks, three training units per week for the experimental group. Later a post–experimental test, similar to the pre-test, was carried out on the two groups, the experimental and control group. The researcher concludes that the exercises that were used in the program had led to considerable improvement of performance by the experimental group.
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 group s. 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 aim of this research is to speed up the offensive tactic by improving reaction time when performing the forehand strike . For this reason, this research adopted the( 24) participants from the first-class table tennis clubs players in Latakia ( junior category ). They were divided into two equal groups (experimental and control group ) . The two samples underwent a pre test to measure reaction time , and they performed the ball driven from the machine test. Then, the experimental group underwent training program designed for four weeks : each week is composed of three training session and each session includes four or five exercises to develop the reaction time in table tennis . The control group underwent their traditional program as usual. Then the two samples underwent a post test , and they also performed the ball driven from the machine test. The searcher used experimental method for two groups (experimental and control) by using the pre and post test to the both groups. Then the results of the two samples were compared between pre and post tests . The researcher concluded that the applied training program affected positively on improving reaction time when performing the forehand strike .
This study aims to find out the relation between agility component and skill to control the ball in terms of performance, the skill to control the ball is one of the basic skills of soccer and it is related to the rest of the skills as is the case for an agility which is closely linked to the rest of fitness elements such as speeding, flexibility and power. The Researcher used the descriptive method so as to appropriate the research objectives. The study sample included (14) players from theTadamon sports Club in Latakia aged 13_ 14 years, The agility and the control of the ball were tested, to find out the relation between. The statistical results of the study shows a significant correlation between the agility element and skill of ball control and that refers to the effect of the agility on the performance of the skill of the ball control in soccer .The researcher recommended the development of agility element as an adjunct to perform the skill of the ball control.
The presented paper deals with an implemented speed sensorless direct vector control (DVC) technique based on stator flux orientation algorithm to estimate and control rotor speed of three phase induction motor (IM). The driver system is presented in this paper has a three phase bridge uncontrolled rectifier and space vector pulse width modulated (SV-PWM) inverter to drive and control the speed of the (IM) at different mechanical load conditions. The rotor speed has been obtained by slip frequency estimation instead of use feedback speed sensor. The structure of Volt/Freq via PI-controller is used to control and adjust speed accuracy between required and estimation rotor speed to precise speed response. The proportional and time integration controller values obtain by Ziegler-Nichols closed-loop tuning method. Computer simulation results with Matlab/Simulink program show an acceptable speed control response, minimum error at steady state and dynamic condition, a results show also the stator voltage, current and flux estimated in direct-quadrate of stationary and synchronous reference frame at variation in load up to (10 N.m) beside the synchronous, slip and rotor speed estimation are varied between (250-1486 rpm). Keywords: Induction Motor Drive System, Direct Vector Control, Speed Sensorless.
