The aim of this study was to evaluate the effects of plyometric training on a group of athletes who practice rhythmic gymnastics. Three evaluations were made: initial, intermediate and final assessments. The following tests were proposed, which were carried out using Optojump: squat jump, stiffness, gymnastic jump, squat, standing calf exercises. The following exercises were proposed during the experimental protocol: drop jump and step-climbing. The statistical analysis performed (non-parametric Wilcoxon test) showed the validity of the experimental method with significant differences between the two work methods for some tests only.
