A1 عبد الحسين، نعيم A2 إبراهيم، حذيفة AB The research included the introduction, where the researchers mentioned the importance of badminton as it is one of the interesting sport activities for the players and is one of the best ways to spend leisure time on the social level. The research problem was through researchers observation some players who have weak technical performance between the sections of the consistency of the skill of the drop shot (preparatory, main and final), especially in the final section, which concentrated at the end of the effort and strength of the skill is starting of shuttle and the racket of the most important variables that contribute to the success of the effectiveness of the skill of drop shot. The research aims to identify the effect of biochemistry prepared exercises of starting variables of the front drop shot in badminton among Babylon University team. The researchers assumed that the prepared exercise biochemistry positively affect the start of front drop shot among the participants of the research sample. The researchers used the experimental approach due to its suitability of the nature of the research. The research community of players were selected from the team of the University of Babylon badminton team totaling (6) players, representing the research community and sample. The researchers used in the field research procedures a Japanese made Sony camera with a frequency of 25 r/s (2) and has other imaging with the speed of 1,200 images per second. During the procedures analysis and extraction of the starting variables values of players sample which an angle speed and height of starting the shuttle and its angle starting point. The researcher used Spss in processing of statistical processes and research, after analyzing and discussing the results, the researchers concluded the effect of biocinamatic exercises on the improvement of the technical performance of the front drop shot in badminton in the starting variables under study. The researchers also recommended a need to use Kinematics analysis in the preparation of training modules for badminton players to find out the strengths and weaknesses of the technical service performance as a biochemistry skill for basic badminton skills.
