<![CDATA[The aim of the study is to identify the contribution ratio of peak neural activity to certain biomechanical variables in the first phase of the clean and jerk lift for female weightlifters of Erbil Sports Club. The researcher hypothesized that there is a statistically significant relationship between the peak neural activity index of the primary muscles involved in performance and some biomechanical variables of the first phase of the clean and jerk lift in female weightlifters of Erbil Sports Club. The researcher adopted the descriptive analytical method in this study due to its suitability to the nature of the research. The research sample consisted of eight female weightlifters from Erbil Sports Club who participate in local championships and are classified within the women's category across different weight classes. The researchers concluded that a significant loss of strength was observed due to poor utilization of the mechanical characteristics of movement, as indicated by angular indicators and the linear bar path length. Additionally, the close contribution ratios suggest the integration of all variables in the weightlifting process, with each playing a key role in achieving optimal performance. Therefore, the researchers recommended focusing on increasing strength levels during the pushing phases and taking advantage of the appropriate linear bar path length to improve performance in the final phase, as well as performing balance and stabilization exercises to enhance the ability to control the bar during the final three phases of performance.]]>
