The effectiveness of throwing a hammer is one of the of games that require high-level technical performance and requires that the archers possess a correlation in Physical abilities such as types of strength rotational speed and compatibility as well as mastering the technical aspects according to the mechanical conditions that characterize this effectiveness, Through the experience of field researchers in the field of athletics, especially in throwing events, he noted that there is a low level of digital achievement and a large difference between the numbers recorded in this event for the youth category between the countries of the world and what is recorded for hammer archers in Iraq. The importance of research in preparing the momentary strength exercises and the strength distinguished by speed with electrical stimulation (EMS) and knowing their effect on some vital mechanical variables and the level of archers achievement of the category (youth) The research assumes that there are statistically significant differences between the pre and posttests of the research sample in values(Angular transmission speed, Hammer launch speed, The instantaneous strength of throwing for the full performance of the two legs , The instantaneous strength of throwing from a steadfast leg. The instantaneous push time of the arms at the moment of throwing , The instantaneous strength of the arms at the throwing, Completion distance for full performance). The implementation of the training curriculum took 12 weeks, at the rate of (3) training units per week, i.e. with a total of (36) training units during the research period. The researcher has concluded several conclusions, the most important of which were the effectiveness of exercises (instantaneous strength and strength distinguished by speed with electrical stimulation), which were used within the prepared training Approach In improving the values of the number of biomechanical variables at the moment of throwing, which had a significant impact on the Evolution of achievement.
