The aim of this paper is to: 1. Identifing the speed distinctive strength values for each of arms, back, and legs muscles. 2. Identifing the heights and deviations (absolute and relative) of barbell in snatch. 3. Identifing the relationship between speed distinctive strength of arms, back, legs muscles with heights and deviation (absolute and relative) of barbell trajectory during snatch. The scopes of research included the following: 1. Human scopes; Nineveh team of weight lifting. 2. Temporal scopes; started from 20/3/2012-27/3/2012. 3. Spatial scopes; weight lifting hall, training center in Al-Futtowa Club/Nineveh. A descriptive method has been used by the researchers, the sample consisted of (6) weight lifters selected namely as being the candidates of province of Nineveh sports. Questionnaire has been used for measurements and analysis of data techniques. The data were statistically treated using arithmetic mean, standard deviation, coefficient of simple correlation; this has been applied via SPSS. The study concluded the following: 1. The increase of speed distinctive strength of arms muscles reduces the weight deviations (relative and absolute). This is done between the widest intrinsic deviations of barbell towards the weight lifter. This is happened during the weight drop and fixing deviation point in squat of earth gravity line. 2. There is no significant relation between the speed distinctive strength and the variables of heights (H1-H11) and deviations (D1, D2, D3, D6) for each of arms, back and legs muscles. The study recommended the following: 1. Developing the speed distinctive strength of weight lifter because it can be one of the basic elements of weight lifting. 2. The necessity of using weights less than 60% in which may lead to increase the speed distinctive strength for all parts of the body of weight lifter. 3. Conduct another studies on other forms of musculature strength and join them with other biomechanics veriables. 4. Conduct similar studies on basic elements of general physical ability.
