Abstract

This study aimed to identify the values of selected kinematic variables among Jordanian female weightlifters in the Snatch at a weight of 69 kg by using different distances between the two grips. Furthermore, the study explored the optimal grip distance that achieves the best valuable kinematic variables affecting performance. The researchers used a descriptive approach with a sample consisting of the best Jordanian female weightlifters in the Snatch at 69 kg. The study included three types of distances between the two grips. The researchers utilized standard deviation, arithmetic mean, frequencies, and percentages for statistical data processing. The study results showed that the kinematic variable values among the sample were within results achieved universally, such as the time at the end of the first and second pull phases. However, some kinematic variables among the sample exceeded universal results, including the angles of the knee and hip at the moment of grabbing the barbell off the ground. Additionally, some kinematic variable values among the sample were lower than the universally achieved results, such as the angle of the knee during the first and second pull phases. Notably, the angle of the arm was determined to be the best option for establishing the distance between the two grips, achieving the highest percentage (61%) of kinematic values compared to universally achieved results. The researchers recommend using kinematic analysis in determining the optimal distance between the two grips.
