Brief summary: 1541/5000 The aim of the Bulgarian squat is to improve the hamstring strength and the stability of the knees, thus reducing asymmetries in the lower limbs. It consists in achieving greater strength and stability of the lower limbs to adapt the athlete to the demands of training and competitions as safely as possible.

The main objective of the study is to assess the effectiveness of the Bulgarian squat, in the improvement of asymmetries in lower limbs; improving hamstring strength and knee stability.

Randomized, simple blind clinical study. 30 soccer players will be randomized to the study groups: experimental (Bulgarian squats) and control (non-intervention team routine). The treatment will last 4 weeks, with 2 weekly sessions of 10 minutes each. The study variables will be: lower limb strength (vertical jump with the My Jump 2 application), lower limb stability (Y ™ -Balance test) and lower limb asymmetries (Triple Hop Test, Single Hop Test for Distance and Functional Movement Screen) The normality of the sample will be calculated using the Kolmogorov -Smirnof test. 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.

An improvement in the strength, stability and asymmetries of the lower limbs in soccer players is expected.
