| The study aimed to: Recognizing the values of a number of kinematical variables for the performance of the forehand clear stroke for badminton players. Recognizing the values of the accuracy test for the performance for the forehand clear stroke of badminton players. Recognizing the relationship between a number of kinematical variables and the accuracy values of the forehand clear stroke for badminton players. In order to verify the objectives of the study, the researcher had assumed the following: - There is a significant relationship between the values of a number of bio kinematical variables and the accuracy values of the forehand clear stroke for badminton players. The researchers used the descriptive approach with the correlational style, for its suitability to the study nature, The research sample was selected from the players of the elite clubs registered with the Iraqi Badminton Federation, and the research sample consisted of (7) players. The researcher used the resources, scientific references, interviews, questionnaires, testing, measurement and scientific observation as means of data collecting, the study included biokinematical variables, and the accuracy of the forehand clear stroke skill. The main experiment was conducted in two different locations due to the presence of the research sample (4) of them representing the Iraqi national badminton team in Baghdad and (3) players representing the Akad Sports Club in Erbil province, and in order to achieve the first scientific and technical observation, two digital cameras were used. At a speed (240 f /s), the first camera was placed on the side of the player's hitting arm at a distance of (4 m) and with a lens height (1.25 m) , and the second was placed in front of the player at a distance of (3.35 m) With a lens height (1.25 m). In order to achieve the second scientific and technical observation, two digital cameras were used. The first camera was placed on the side of the player's hitting arm at a distance (5.35 m) and a lens height (1.29 m), it was set at speed (300f /s), and the second camera was placed in front of the player at a distance (3.70 m) and with a lens height (1.29 m), and it was set at speed (210 f/s). The data were statistically handled using the (SPSS) program to obtain (the arithmetic mean, standard deviation, coefficient of variation, simple correlation coefficient, and T-test for independent samples. The researchers concluded: - The variables (horizontal displacement, horizontal velocity and velocity resultant) for BMC in the final phase of the forehand clear stroke skill had a positive significant relationship with accuracy. - The shuttlecock starting velocity in the forehand clear stroke skill had a direct relationship with accuracy. - Accuracy has a direct relationship with variable of the striking arm wrist joint angle and inversely with the forearm angle with the racket variable at the moment of maximum return of the racket in the forehand clear stroke skill. - The relationship was direct between (shoulder angle, forearm angle with the racket) variables (each separately) with the accuracy at the moment of shuttlecock impact in the forehand clear stroke skill. - The increase in the angular deference of the forearm with racket was significantly correlated with accuracy in the main phase of the forehand clear stroke skill. - There is a direct relationship between the angular velocity of the forearm with the racket variable with the accuracy in the main phase of the forehand clear stroke skill. Through the conclusions, the researchers recommend: - The necessity to direct the players to pay attention to the ideal angles of technical performance of badminton skills. - Directing the coaches to use a kinematic analysis programs or seeking the help of an expert and specialist in kinetic analysis to correct some of the players' performance errors that are not seen with the naked eye. - Paying attention to the results of the current study for use by workers in the field of badminton training and education. | ||
