• Resumen

  • 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.
