Brief summary

The goal of this clinical trial is to analyze the effect of the electrical stimulation superimposed onto movement in healthy semi-professional athletes who sustained a type 3a/3b hamstring strain injury. The main questions it aims to answer are: * Is NMES+ useful for the treatment of type 3a/3b hamstring strain injury? * Does NMES+ improve the quality of the injured muscle tissue? Participants will follow a 3 week protocol, following the latest evidence available.\[describe the main tasks participants will be asked to do, treatments they'll be given and use bullets if it is more than 2 items\]. If there is a comparison group: Researchers will compare \[insert groups\] to see if \[insert effects\].

Interventions

DEVICENMES+

The Treatment Group will follow the rehabilitation protocol with the addition of the NMES+. 1st/2nd Week at 35 Hertz. 3rd/4th Week 50 Hertz. 5th/6th Week 70 Hertz.

PROCEDURERehab

The Control Group will follow a protocol based on the latest available guidelines for the rehabilitation of the hamstrings lesions. A weight-bearing protocol with a week by week progression on load, repetitions and sets.
