Using a momentum device to determine the time and distance of maximum arm strength and its relationship to a swimmer’s achievement (50 m) in freestyle.

Abstract

                 The importance of the research came from using a device designed to measure the maximum driving force of the arms and for freestyle swimming, and to evaluate the strength of the arms of each swimmer quantitatively separately, to be a working guide and a basis for coaches to adopt in their training curricula in order to develop achievement. The problem of the research emerged, which is the lack of a device or scale through which the amount can be measured. The swimmer's driving force inside the water, in quantitative terms, is the force that causes the swimmer's body to move through the use of arm and leg movements inside the water. And setting numerical values ​​for the time and distance of the emergence of this force, which were not previously studied in detail, for the arms and for free swimming, through the use of a motive force device and identifying the level of the maximum motive force for each swimmer, and for the arms in particular, to find out the best production of that force, in addition to determining the time and distance for the emergence of that force and setting It has a numerical value measured in units of kilograms and its parts per swimmer. This is to determine its effect and its relationship to the achievement of short-distance 50-meter freestyle swimmers. The study aimed to identify the time and distance of maximum arm strength for 50-meter freestyle swimmers and to identify the relationship between the time and distance of maximum arm strength and achievement for 50-meter freestyle swimmers. The researcher assumed that there are statistically significant differences between Time and distance of the maximum driving force of the arms and swimming achievement (50 m) for free swimming The researcher used the descriptive approach. As for the research population and sample, the research population was determined and they were (10) swimmers from the Najaf Youth Swimming Club, from whom the research sample (6) swimmers were chosen intentionally. The researcher also concluded that there are different differences in the amounts of driving force in the arms for freestyle swimming. The increase in the amount of momentum of the swimmer increases the speed of the swimmer and thus reduces the time it takes to cover the distance for free swimming. The researcher recommended adopting the device used by swimming coaches to determine the levels of momentum of the arms of swimmers to detect their levels of progress.
