THE EFFECT OF THE DISABLING FORCE USING PARACHUTE IN DEVELOPING THE FAST AND EXPLOSIVE FORCE IN TERMS OF THE INSTANT PUSH TOWARDS THE TWO STAGES OF THE APPROACH AND THE UPGRADE TO THE LONG JUMP FOR YOUTH

The researcher moves towards delineating one of the assisting training tools which is the new training method through parachutes, using them as resistant force in an airy medium via drag force benefiting from the mechanical laws in determining training hardness of long jump players through controlling the umbrella surface that is exposed to air and the player's body speed. This resistance, then, will lead to a burden on working muscles which will heighten the level of explosive and speedy power which will be reflected on the level of achievement. It will also lead to link between steps of closeness and rising without a decrease in in speed, and, here lies the significance of the study. Therefore, in order to have an improvement in the level of special bodily abilities by using assisting tools so as to achieve integration in bodily abilities and performance especially in the final step and rising to gain good accomplishment. The researcher made use of the experimental approach of the one experimental group design due to its appropriateness to the nature of the study. Sample of the study is deliberately selected, comprising of (5) players in Diyala high jump under 20 years team 2014-2015. Moreover, the study field procedures included photography, tests and measurements used in the research. Photography is included in the physical tests which comprised speedy and explosive power. These trainings are applied within the main part of the training unit, lasting from 45 to 50 minutes, 3 units per week for a period of 8 weeks, with a total of 24 training units. The load is gradually increased each two weeks as trainings were repeated each two weeks. The load is gradually increased in the other two weeks and so on. For the sake of having an effective and influential training based on scientific bases, the researcher adopted the frequent training method, then resting duration is specified to be the ratio between effort time and rest time. The study concluded that using force according to drag force law via parachutes (as training tool) has positively influenced the development of speedy and explosive powers of the study sample.
