The effect of exercises with central and peripheral resistances and their impact on the speed-distinguishing strength of the muscles of the arms and legs in terms of stability and movement and the completion of the 50-meter freestyle swimming for youth

Abstract

The research aims to prepare exercises with central and peripheral resistances for the 50-meter freestyle swimming, to identify the effect of using exercises with central and peripheral resistances in developing the speed-distinguishing strength of the muscles of the arms and legs from stability and movement for the research sample, to identify the effect of using exercises with central and peripheral resistances in the achievement of the 50-meter freestyle swimming.

The experimental method was used and in the design of one group, the researcher chose the sample in the intentional way, and they are the youth swimmers for ages under 19 years old for Sayed Sadiq Sports Club, where (7) swimmers were selected out of (12) swimmers, which constitute (58.3%) of the original community of the sample and tests Multiple dependent variables (strength characterized by speed of the muscles of the arms and legs in terms of stability, movement, and achievement). The period of the curriculum was central and peripheral resistance exercises that lasted for (12) weeks. The curriculum was implemented by three units per week, with a time of (22-55) minutes per unit. Where it was measured and tested in pretests and post-tests, the researchers concluded that training with central and peripheral resistances had a positive effect on the development of physical abilities (the strength of the muscles of the arms and legs in terms of stability and movement), that training with central and peripheral resistances had a positive effect on developing Achievement among the research sample members.
