أثر التغذية المرتدة البصرية و اللفظية على تطوير بعض المتغيرات الكينماتيكية لمهارة البدء في السباحة الحرة

Abstract EN

The study aimed at identiyng the effect of visual feedback on some kinmatics in skill start swimming on a sample of 20 swimmers less than 51 years old they are engaged in the pool club 18 february in Ouargla, The research sample was chosen by the intentional method swimmers who mastered the skill of starting from the top, and use the two-groups; the first group includes (10) swimmers which received visueal feedback, and a group of (10) swimmers which received literal feedback.

One video filming cameras (Gopro Hero 4) (30-Hz) were used with (Dartfish Edition MPT34 M pro 5.5) analytical software order to find the value of kinematics parameters.

The components consisted of: (Preparation phase, starting stage, flight phase).

The results the study suggested that visual and verbal-based kinetic analysis feedback has a role in improving the level of kinetic parameters study in the speed of 50 metres in favor of the members of the visual feedback group.

The researchers recommended that it is necessary to use of the results of kinematics analysis to evaluate swimmers' performance when giving the feedback in order to detect the points of weak performance for further modification.
