المسافة المثلى بين القبضتين في رفعة الخطف من منظور كينماتيكي

الملخص EN

The purpose of the study to identify the values of some variables kinematic performance motor with player Jordanian team to weigh 85kg using different types from the distance between the two fists in the snatch, and compare it with available universal values, and exploration the best way to distance between two fists, Which achieve the best valuable variables for the kinematic affecting the achievement of digital compared to idealism values.

The researchers used the descriptive approach with his style survey.

The study sample consisted of the best player in the Jordanian team to the snatch in the 85 kg weight.

The study included (3) types for the distance between the two fists (way of the arm and shoulder, and the distance between elbows and the angle), and (17) the dependent variable.

The researchers use frequencies, percentages for statistical data processing.

The study results showed that there are some values of the variables kinematic among a sample study were within of the results achieved universally, such as the maximum deviation of the barbell at the end of the first pull phase, and the angle of the hip to grab a moment of barbell on the ground, and the angle of the knee at the end of the first pull phase.

While there have been some valuable variables kinematic among a sample of a larger study, the results achieved universally, as a time first and second pull phase and a decrease in the speed of barbell at the end of the first and second phase.

The way the arm and shoulder of the best types used to determine the distance between the two fists, which achieved the best percentage values kinematic proportion for the same values achieved universally.

The researchers recommend using the analysis kinematic in the process of determining the distance between the two fists.
