Abstract
Abstract The research aims at : 1. Identifying the values of the mechanical power of the unsuccessful and successful attempts in snatch lift for the research sample . 2. Identifying the differences between the mechanical power of the unsuccessful and successful attempts in snatch lift for the research sample. 3. Drawing the trajectory of the mechanical power of the unsuccessful and successful attempts in snatch lift for the research sample . The researchers have adopted the descriptive approach on the comparative style for its convenience to the nature of the research .The sample has included (7) advanced weight lifters participating in Iraq clubs championship for the advanced in 2009 . The experiment of the research has been photographed on 26-27/3/2009 in Al-Tamim Hall for weight lifting –Baghdad for all weight lifters participating in Iraq clubs championship for the advanced . The variable of the mechanical power and the related variables which can serve the research have been analyzed . The data have been treated statistically by using SPSS with using ( mathematical mean , standard deviation , percentage law , and t-test for the connected sample ) . The researchers have concluded the following :- 1. The absence of moral differences for the mechanical power between the unsuccessful and successful attempts for the stages of trajectory of the bar weight in snatch lift for the research sample . 2. Conformity of the trajectory of the mechanical power for the unsuccessful and successful attempts and according to the phases of the trajectory of the bar in snatch lift for the research sample . 3. The increase of mechanical power trajectory has gradated upwards from the first draw phase passing the phase of the knees and till the end of the second phase for the unsuccessful and successful attempts for the stages of weight drawing in snatch lift for the research sample . 4. Decreasing the trajectory of the mechanical power downwards in the phase of flying and falling for the unsuccessful and successful attempts for the phases of the trajectory of the bar in snatch lift for the research sample .
