Brief summary
Introduction. The high rate of recurrence and clinical involvement of muscle injuries in lower limbs, makes the hamstring musculature a very important structure in the development of athletes. Excentric movements, where eccentric force and flexibility are fundamental, and the quadriceps-hamstrings contraction cycle are risk factors for hamstring muscle injury. Aim. ascertain the effectiveness of plyometric and excéntric exercises in the improvement of hamstring strength. Study design. Randomized, prospective, multicenter, single-blind clinical study with athletes. Methods. This study will be carried out with a sample of 40 women, federated players from 18 to 30 years old. They will be randomized into two groups: experimental (plyometric work and eccentric exercises) and control (eccentric exercises). The intervention will last 6 weeks in which, before each training, they will carry out the intervention, for 20 minutes, 3 days a week. An inter-judges piloting will be carried out. We will analyze the normality of the sample with the Kolmogorov-smirnov test and for the inferential analysis, we will use the t-student test of paired data to observe the difference between each evaluation in each study group, and the repeated measures ANOVA to calculate the effect intra and intergroup. Using Cohen's formula we will calculate the size of the effect. Expected results. The eccentric work along with the plyometrics improves strength in hamstrings, jumping and stability.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline hamstring strength after treatment and at 1 month | Screening visit, within the first seven days after treatment and after one month follow-up visit | The mobile application Nordic will be used to assess the strength of the hamstring muscles. With the athlete kneeling on the floor, fixed by a partner from the ankles, she will drop down forward. The evaluator will be on the side, recording with a smartphone (Iphone 7) to measure the moment when the subject uncrosses the arms. The test will be carried out up to three times, taking the measures of the angle of rupture in the exercise (angle that forms the trunk with the ground considering the position of the tibiae). The unit of measure the breaking angle. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline the jump after treatment and at 1 month | Screening visit, within the first seven days after treatment and after one month follow-up visit | With the mobile application My jump 2.0 the jump will be measured. The athlete will be located 1.5 meters from the evaluator, who will be in front of her with a mobile (iPhone 7 model) at ground level. The test will consist of the realization of a Counter Movement Jump (CMJ). The unit of measure of the jump of the application will be the Newton. |
| Change from baseline lower limb stability after treatment and at 1 month | Screening visit, within the first seven days after treatment and after one month follow-up visit | With the Y-Balance test the lower limb stability will be measured. The player will be placed in the center of an inverted Y-shaped figure, and in monopodal support on the leg to be evaluated. 3 attempts will be made for each of the scopes (anterior, posteromedial and posterolateral). The distance will be measured in centimeters, taking as value the arithmetic mean of the three attempts made in each range. The Y-shaped figure will be made with tape on the floor. The distance calculation will be carried out with a tape measure. |
