Kinematic Analysis of the Snatch Technique in High Performance Weightlifters

The overall objective of this work is to compare the differences between the execution of snatches performed by high-performance male and female weightlifters as
well as the lateral symmetry of the gesture through the 2D reconstructions of the
kinematics. Seventeen weightlifters (6 women and 11 men) from “Liga Antioqueña de
Levantamiento de Pesas” participated in this study. Their movements were captured
in the frontal and sagittal plane by means of 2D videogrammetry. The articular kinematics of both men and women present the same bilateral symmetry. However, the
transition and turnover phases exhibited the most significant changes. Differences
between the two study groups can be found in their joint movement range, barbell
vertical velocity, and base of support; the latter two were greater in women. This
changes can be useful to provide coaches with basic biomechanical tools to improve
their practice and to personalize training.
