The research aims at :<br /> 1. Identifying the values of some kinematical variables of the kinetic track of the weight for the three attempts with various intensities in snatch lift for the research sample .<br /> 2. Identifying the differences between some kinematical variables of the kinetic track of the weight for the three attempts with various intensities in snatch lift for the research sample .<br /> 3. Drawing the kinetic track of the weight for the three attempts with various intensities in snatch lift for the research sample .<br /> The sample consisted of (6) advanced weight lifters whom they have and the achievers of advanced ranks in Iraq tournament 2010 . So ,they have been selected randomly for their success in the three attempts according to their serials in snatch lift . The researcher has adopted the technical scientific observation , the test and measurement , and analysis as means of collecting data to obtain some kinematical variables of the weight . Video camera has been used and placed on a distance of (8) m from the right side , so the height of the lens is ( 1.50)m from the stage .The speed of video camera is (25)Picture/second . We have obtained the variables of deviation and heights in snatch lift from weight movement track to the stages of snatch lift ( the first draw , knees , the second draw , flight , downfall stages ).The researcher has used the following statistical processors (arithmetical mean , standard deviation , T-test , and percentage rule ) .<br /> The researcher has concluded the following :<br /> 1. There were no significant differences between the kinematical variables ( H5,H6,H7 ) of the barbell trajectory between the first attempt and the second attempt also with third attempt advantage to the first attempt in snatch lift.<br /> 2. There were no differences in the values of some kinematical variables of the barbell trajectory for the three attempts in snatch lift which were larger than Iraqi extents of the previous studies like (D3,D5,D6) variable in deviations as well as (H8) variable in the heights .<br /> 3. The form of kinematical of the barbell trajectory of the of the barbell for the third attempt in snatch lift for the sample has been better than the first and second attempts for the kinetic track has been close to the gravity line which is for the benfit of the weightlifter during performing weight lifting. While the form of the kinetic trajectory of the of the barbell trajectory in the first and second attempts was similar. <br /> 4. It has been observed that all Iraqi lifters jump back during performing the three attempts in snatch lift for the sample .
