أثر تمرينات وفق النشاط الكهربائي للعضلة الفخذية في تطوير بعض القدرات البدنية الخاصة و المتغيرات الكينايتكية للأمتار العشرة الاولى لعدائي 100 م

Abstract EN

The 100 m Activity is one of the activities of fun and thrilling for spectators and players in terms of kinetic competition and performance, so these activities deal with the maximum effort of the racer and the performance accuracy from the first moment of the start to reach the finishing line.

Therefore, the researcher intended to use the modern technology devices in the preparation of specialized exercises.

By using a device (EMG),we can know the electrical activity of the muscle to stand up on the weaknesses in the working muscles and those which are adverse in order to prepare exercises that help in reaching the ideal muscular balance during doing the motor duty as diagnosing the weakness by the naked eye cannot be done without the use of modern technical equipment to develop the physical abilities (speed of response and the explosive ability of legs and arms) and the kinetic variables of represented in (amount of movement, work done, kinetic energy) for the ten meters in the first 100 m start due to the importance of this stage of achievement time.

Thus study aimed to identify the impact of the stomach exercises according to the electrical activity of the femoral muscle in some physical abilities and kinetic variables for the first ten meters of the 100m runners.

The research population was represented by the tracking and field players of Karbala Club among the young players for the activity of 100 m and totaling (20).

The research sample was selected randomly, which consisted of (12) runners representing a set of clubs.

The researcher used the experimental approach with the method of two equal groups and all the variables under study were collected.

The researcher reached to a set of conclusions, including: that specialized exercises in accordance with the electrical activity had an effect in improving the physical capacity of the muscle (response speed and the explosive ability of the two legs and arms) for the first ten meters of 100 m start.

In addition, the specialized exerciseshad an effect on the development of kinatic variables as a result of the evolution of the physical abilities of the first ten meters of 100 m start.
