Plyometrics in the Ankle Stabilizing Muscles in Improving Balance in Ballerinas

Efficacy of an Intervention by Plyometrics in the Ankle Stabilizers in the Improvement of the Balance in Salsa Dancers From 18 to 25 Years. A Randomized Clinical Study.

Balance is essential for successful dance performance. The effort of salsa dancers is given by the levels of stability, produced by the muscular activation of lower limbs.

The objective of the study is to assess the effectiveness of an intervention of plyometric exercises in the improvement of balance in salsa dancers from 18 to 25 years.

Randomized clinical study. 40 dancers will be randomized to the two study groups: experimental (application of plyometric exercise protocol) and control (without intervention). The treatment will last 5 weeks, with 2 weekly sessions of 25 minutes each. The dependent variables will be: equilibrium (measured with star excursion balance). The sample distribution will be calculated using the Kolmogorov-Smirnof test. The changes after each evaluation will be calculated with the t-student test. With an ANOVA of repeated measures, the intra and intersubject effect will be observed. The effect size will be obtained with Cohen's formula.

It is expected to see improvement in the stability of the ankle and the level of balance in the dancers.
