تأثير بعض التمرينات في تطوير مرحلة الدوران و الإنجاز في سباحة 100 م حرة للسباحين الشباب أعمار 15-16 سنة

Abstract EN

The research aims to identify the effect of some exercises on the development stage of rotation and achievement in the 100 m free swimming among swimmers and the effect on the performance time from the distance of (5 m) before the rotation until the arrival of swimmer distance of (10 m) after rotation.

In order to achieve the research objective, the researchers selected 16 swimmers aged 15-16 years randomly, divided into two groups, the first experimental (8) swimmers as experimental group, and the second (8) swimmers as a control group.

The experimental group carried out the exercises prepared by the researcher within the syllabus of the daily training unit, and the control group used the traditional training method according to the method prepared by the trainer and at the same time allocated to the exercises of rotation.

The researchers conducted the test before and after the duration of the study, which lasted 12 weeks, three training units per week.

The results were analyzed statistically for both groups where the researchers found that the swimming time of 100 m has developed in both groups, but the group that used the exercises prepared by the researchers were the best at performing the distance of the last five meters and the distance of 15 allowed by law, so the researchers recommend to give importance to the exercises in the stage of rotation because of their effect in achieving the level of achievement in the 100 m free swimming.
