التدريبات الغرضية و تأثيرها على الحركة الدورانية للجسم حول المحور الطولي لسباحتي الزحف على البطن و الظهر

Abstract EN

The research aims to identify purposeful exercises using tools and their impact on the rotational movement of the body around the longitudinal axis (time 50 m-the number of intensities of 50 m-the level of performance of the rotational movement of the body around the longitudinal axis) for the crawl and backstroke swimmers the most important results revealed that there were differences in the rates of change between the two dimensional measurements of the experimental and control groups (50 m time-the number of 50 m intensities-the level of performance of the rotational movement of the body around the longitudinal axis) for the crawl and backstroke swims, as it ranged between (5.64% : 112.3%) in favor of the dimensional measurement of the experimental group, and it ranged between (2.56% : 61.34%) in favor of the dimensional measurement of the control group with a difference between the two groups.

it ranged between (3.02% : 50.96%) in favor of the experimental group.
