The relationship between strength- distinguish by speed (for legs and arms) and some of the mechanical variables with the accuracy of shooting by jump in team handball
Abstract
Abstract The idea of the research is summarized in studying some of mechanical variables for the research sample and their relationship with the accuracy of shooting by jump in team handball. The research aimed to identify: 1-Values of strength- distinguish by speed for hand ball players. 2- Values ofmechanical variablesduringthe shooting by jump in team handball. 3-Values oftheaccuracy of shooting by jump in team handball. 4- The relationship betweenstrength- distinguish by speed and the accuracy of shooting by jump in team handball. 5- The relationship betweensome of the mechanical variables and the accuracy of the shooting by jump in team hand ball. 6- The relationship betweenstrength- distinguish by speed andsome of mechanicalvariables of shooting by jump in team hand ball. The researchers used the descriptive method for its convenience to the research nature, the research community was consisted of the(18) youth handball players in Nineveh, while the research sample has been selected intentionally from players who use the right arm in shooting whom they were 8 players, the researchers used test , measurement and scientific observation as a tools of data collection , the scientific observation was carried out by using (Casio exlim) digital camera with speed of ( 120 f/ sec)and placed ( 9.02 m) on the right side of the player with a lens height of ( 1.25 m) to obtain the values of some variables for the players and the ball , a yard stick one meter was used and filmed in both positions (horizontal and vertical) to calculate the real dimensions of picture . Data were statistically handled treated by applying (SPSS) program to obtain (the arithmetic mean standard deviation, the simple correlation and t test for independent samples)
