The aim of the study was to obtain information about the proximity to perform the L-Sit Cross (LSC) element of strength hold in still rings. The production of isometric strength in the LSC in still rings in a group of twenty elite gymnasts was evaluated using a force platform (FP). The participants, who were seated on a FP, exerted a force on the rings to reach the LSC. The vertical force component extracted from the F / t curve (20 Hz) was analyzed, which reflected the weight released when a force was applied in a period of maintenance of the maximum isometric force. The normalized maximum and mean isometric forces were extracted. Results showed large differences (p<0.001, Cohen’s d = 1.6) between performer (P) and non-performer (NP) gymnasts of this element. P gymnasts produced a greater isometric strength level owing to their greater experience in training this element. This information can be useful to coaches in order to determine how close a gymnast is to performing the LSC.
