Effect of Symmetrical Exercises on Some Physical Variables and Level of Performance in Running 4 x 400 Relay Effectiveness

Abstract

One of sporting events that received great attention and in particular is
track races and field. great progress in digital achievement of relay
competitions, especially ran of short distances 4 x400 meters
Effectiveness that activities have own physical and technical
characteristics that must be enjoyed by two short distances, such as
speed And distinctive strength of speed, as all physical capabilities of
hostility are developing in a balanced manner with technical aspects of
enhancing appropriate technique to reach good digital achievement. One
of problems facing hostility in effectiveness of 4 X 400 meters is
continuing is delivery of stick during performance of effectiveness in a
full way and it is concern of all those interested in this Effectiveness,
where delivery and receipt stage within box is one of important things that
affect level of performance and digital achievement of team and thus
achievement is determined by speed and accuracy of delivery and
receipt stage, as well as lack of knowledge of coaches and athletes about
practical benefit of symmetrical training by introducing m in training. study
aims to Identify effect of use of symmetrical exercises on some special
physical elements for purpose of developing acceleration during delivery
and receipt at hostile effects 4 x 400 meters follow performance and
researcher used experimental curriculum for research sample (19-20)
year of (16) runners, represent 100% of original research community.
Most important recommendations were: Considering rest periods in a way
that suits physical effort, where it is between repetition groups within
training. Use of symmetrical exercises to develop parts of technical stages
of rest of athletics activities, as considered pillar of performance for each
event and in a varied and interesting way, main part of training units.
