Brief summary: The specific training of the elastic-explosive force of the muscles involved in vertical jump and active mobilizations is used to improve the quality of the jump. It is also intended to reduce the loss of centimeters, recovery times and fatigue produced during a series of vertical jumps.

The objective of the study is to assess the effectiveness of active mobilizations together with specific training in lower limbs, in ankle mobility, the perception of effort and the height and resistance of vertical jumping in amateur basketball players.

Randomized clinical study. 50 basketball players from 20 to 35 years will be randomized to the study groups: control group (resistance strength exercises, elastic-explosive force) and experimental group (resistance strength exercises, elastic-explosive force together with active mobilizations). The dependent variables will be: repeated jump (15 second Jump test, my Jump 2), maximum vertical jump (CMJ free arms, my Jump 2), subjective perception of effort (Borg scale) and ankle dorsiflexion (goniometer). The sample distribution will be calculated using a Kolmogorov-Smmirnof analysis. The changes after each evaluation will be analyzed with the t-student test and with an ANOVA of repeated measures the intra and intersubject effect will be observed. The effect size will be calculated using Cohen's formula.

It is expected to observe an improvement in the resistance of vertical jumps, with a decrease in the loss of centimeters in the repetitions of jumps.
