دراسة مقارنة لمقادير القوة الدافعة للرجلين بين أنواع السباحات الأولمبية

Abstract EN

The research significances manifested by identifying the levels of driving force of the two legs for the methods or types of the four types of swimming (free - butterfly - chest - back) and identifying the quantities of each type and quantifying them by means of a special device designed to measure the driving force of the four types of swimming, while the research problem is to identify the numerical value of the driving force in units of a kilogram and its parts for the four swimming methods and the value for each of the four methods as well as for estimating the development of the driving force production for the two legs during the different training periods for each swimming as well as identifying any of these four swimming as a result of the strength through the use of standardized measuring device for that quality., and coaches had numerical data for each swimmer and s of swimming , getting the first and second centers swimmers in the championships held at the country level.

The research objectives were to identify the values of the driving force of the two legs movements for the four types of swimming , and to identify the differences between the driving force of the two legs for the four types of swimming .

As for the research hypotheses , there are different differences in the driving force of the two legs between the four methods of swimming.

The researchers concluded that there were different differences in the levels of the driving force of the two legs for each type of swimming, the force generated for the work of the two legs who work that one (together) is better than the reciprocal movements.

The most important recommendations are to conduct similar studies for different age groups to get acquainted with their driving force and to be recognized by trainers on the strength produced by the swimmer in order to identify the level of progress during periods of training stages
