Brief summary: The objective of plyometric exercises is to improve the range of mobility of the ankle, as well as decrease the stiffness of this joint and increase the strength in the sural triceps, by improving the explosive elastic force.

The objective of the study is to assess the efficacy of plyometric exercises in increasing ankle mobility and increasing strength in the sural triceps, in professional female basketball players aged 18 to 40 years.

Randomized, simple blind clinical study. 48 basketball players will be randomized to the two study groups: experimental (they will perform the Counter Movement Jump (CMJ) and Drop Jump (DJ) exercises) and control (they will follow their usual routine). The intervention will last 4 weeks, with 2 weekly sessions of 15 minutes each. The study variables will be: range of dorsal flexion movement of the ankle (goniometry) and strength of the sural triceps (My Jump 2). A descriptive statistical analysis will be performed calculating the main statistical characteristics. The sample distribution will be analyzed with the Kolmogorov-Smirnov test. The changes after each evaluation will be analyzed with the t-student test for related samples and with the ANOVA test of repeated measures the intra and intersubject effect will be observed. Cohen's formula will be used to calculate the effect size.

It is intended to observe improvement in the range of dorsal ankle flexion movement and strength in the sural triceps.
