简要总结
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.

结局指标
主要结局
Change from baseline hamstring strength after treatment and at 1 month
时间窗: 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.
次要结局
- 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)
- 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)
