The Effect of Fixed Force Exercises by Using Different Tools in the Values of Some Bio Kinematics Variables to the Hit/Spike Skill in Volleyball for Young People

Abstract

The muscular training by adopting fixed foundations is a modern training methods which is concerned

with the development of muscle strength, in fullest stretch This is due to the quality of the exercises that

selected and designed according to the requirements of skill performance which performance is subject to

a set of variables that determine the characteristics of this technical performance of the hit/spike skill, it

causes production of the kinetic system, needed by good skill performance as well as the appropriate correct

compatibility that occurs between the variability in the kinematic and kinetic variables determined by the

stress used is the best way to success performance as well as the stabilization and orientation of muscle

groups to serve skill performance, so the researchers used the experimental method using experimental

design of one group appropriate to the nature of the research, the The study sample was chosen by the

researchers in purposive method, numbering 6 athletes, The researchers were keen to apply the stationary

strength training using different tools for the purpose of some Bio kinematics indicators and the development

of muscle strength for sample members (8) weeks and included (24) training units (3) units per week, The

results of the research was the most important that all the exercises used to develop the fixed force, whether

the muscles of the legs, torso or arms, increased the efficiency of the internal force, the strength of ligaments

in the production of torque force.
