مقارنة تأثير تمرينات بمقاومات مختلفة في تطوير القوة الخاصة للذراعين و دقة الإرسال في التنس الأرضي

Abstract EN

The study's aim is for knowing of the suggested exercises' effectiveness in developing of private power and accuracy of sending in some types of ground tennis and comparing between suggested resistance in developing of private power and accuracy for some types of sending.

The study sample consisted 12 players between ages of 17-18 year, and they have been divided into three groups, each group was consisted 4 players.

The variable was entered on the first group, the experimental variable (training of resistances by using of rubber ropes) and the second group (training by using added weights) and the third group (by using of medical balls).

The results appeared existence of incorporeal differences between the before and after tests for research's groups and in test of eruptive power for the arms for third group and appearing of incorporeal differences for second group in test of distinguished power by speed and appearing of incorporeal differences for all three groups between before and after test in tests of (tolerance of power and accuracy of sending) and also, the second group passed other groups in less test of incorporeal difference in the tests of (tolerance of recommended diversity in training tolerance and for using of help means and power and accuracy of sending) and the researchers has tools in the in the training.
