Effects of plyometric training in young athletes of Rhythmic Gymnastics

Aim: The technical content of a sport such as rhythmic gymnastics, where the Code of Points requires the execution of the jump with an elevation sufficient to achieve the corresponding shape in which the jump reaches a defined and fixed shape during flight, strength, particularly in its expression explosive-reactive and ballistic. Methods: Pilot study, 10 gymnasts, aged 12 and 15 years, randomly Case Group (5 units) & control Group (5 units), subjects with same background athletic discipline of (± 7 years). Kinovea and Golden Ratio. Results: TBF is of ± 3.6 cm CG. FS present initial slight decrease of ± 3.6°, with a subsequent recovery of ± 2.2° during output test. SS is increase ± 8.2° to the right side and ± 8.8° to the left side. CG improved TBF was not significant regards Splits, we note FS decrease of ± 9.8°, and the RSS ± 10.4°. Different situation LSS, that increase ± 13.6°. JRT IG increase ± 2.4 cm, SG instead, is not subjected to conditioning, we see a decrease average of ± 2.2 cm. Zanon's PET, increase ± 5.2 cm for the IG, while for SG they are not occurred particular improvements, but a decrease of ± 2.2 cm. Analyzing the GR diff., in the Snip flexed, CG does not present a particular improvement (± 3,1 cm), while the CG showed a decrease of ± 3.3 cm. VJ passé position, we increase in a bit most significant part of the CG, ± 2,9 cm, unlike the CG that virtually remains stationary, presenting a slight difference in negative of ± 1.1 cm. Groupé jump, improved ± 3,7 cm, other decreased height of ± 3,9 cm. Jump with 360° body rotation, CG increased height of ± 3,1 cm, CG has, again, presented a reduction of ± 3,4 cm. Conclusions: The data collected showed an important improvement in Group case, especially as regards the main variant that we used to test, jump height, while the same has not occurred for the group that has not received the plyometric training, the Control Group, but by recording a small decrease in performance.
