简要总结
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.

结局指标
主要结局
Change from baseline hamstring muscle strength after treatment and at month
时间窗: Screening visit, within the first seven days after treatment and after one month follow-up visit
It will be done through the vertical jump Through the Appstore My Jump 2. The athlete will stand in standing position with the feet in parallel with a separation corresponding to the height of her hips. It will start with a knee flexion of 90º and with the arms along the body. You will be asked to perform a jump by bringing the lower limbs to a triple flexion (hip, knees and ankles). At the same time that it is pushed by pressing on the heels, it will take the arms in the take-off phase above its head. The load will be introduced if there is, in kg, and we will obtain the force time data (in Newton).
次要结局
- Change from baseline stability after treatment and at month(Screening visit, within the first seven days after treatment and after one month follow-up visit)
- Change from baseline asymmetries of lower limbs after treatment and at month(Screening visit, within the first seven days after treatment and after one month follow-up visit)
