简要总结
Football requires a high number of actions at high speed and intensity. The application of plyometrics can improve explosive strength and speed levels in soccer players.
The main objective of the study is to assess the effectiveness of a program based on plyometric exercises for the improvement of the explosive force in vertical jump and the speed in running with and without the ball in soccer players of youth category.
Randomized clinical study, simple blind, with follow-up period. 30 players will be randomized to the study groups: experimental and control. The intervention will last 4 weeks, with 2 weekly sessions lasting 20 minutes. The study variables will be: Vertical Countermovement Jump Test with Arms and Twenty-Centimeter Drop Jump Reactive Strength Index (Explosive Force), running speed without ball and ball (20 meter speed test), hitting speed of ball (Maximal Kicking Velocity Test), hamstring extensibility (Sit and Reach Test) and sural triceps extensibility (Leg Motion Basic). Normality will be calculated using an analysis of Kolmogorov Smirnov. With the t-student test the differences between assessments will be calculated and with an ANOVA of repeated measures, the effect between intersubject will be calculated. The effect size will be obtained with Cohen's formula.
It is expected to obtain an improvement in the explosive force in the vertical jump, as well as in the running speed with and without the ball.

结局指标
主要结局
Change from baseline explosive force in vertical jump after treatment and at month
时间窗: Screening visit, within the first seven days after treatment and after one month follow-up visit
Through the Vertical Countermovement Jump Test with Arms. The subject will be placed in standing position on a contact platform, it should make a rapid downward movement followed by a maximum vertical jump using the arms. The distance jumped in centimeters will be measured.
次要结局
- Change from baseline hamstring extensibility after treatment and at month(Screening visit, within the first seven days after treatment and after one month follow-up visit)
- Change from baseline sural triceps extensibility after treatment and at month(Screening visit, within the first seven days after treatment and after one month follow-up visit)
- Change from baseline running speed after treatment and at month(Screening visit, within the first seven days after treatment and after one month follow-up visit)
- Change from baseline ball hitting speed after treatment and at month(Screening visit, within the first seven days after treatment and after one month follow-up visit)
