Primary purpose: TREATMENT

Brief summary: Investigate the efficacy of the inercial Flywheel training protocol in modifying the architecture and function of the hamstrings in patients with a history of structural muscle injury vs conventional training.

The researchers hypothesize that inercial Flywheel training protocol will be a useful strategy in the modification of the architecture and function of the hamstring in patients with a history of indirect structural muscle injury and decrease the recurrence.

Detailed description: Randomized controlled intervention study

Eligibility criteria: Inclusion Criteria:

* Adults with history of structural muscle injuries type 3 of the Munich Consensus classification for muscular injuries, confirmed by imaging diagnosis no more than 2 years ago.
* The patient must have performed conventional medical and physiotherapy treatment
* Have Returned to their usual sporting activity
* With good mental health.

Exclusion Criteria:

* Suffer from a systemic pathology that could alter the healing biology of the muscle.
* Present other lesions in the muscular group of extrinsic characteristic or not encompassed within type 3 structural lesions such as, for example, proximal or distal insertion tendinopathy, use of semitendinous as anterior cruciate ligament graft.
* Prior knee or hip surgery.
* Having been infiltrated with platelet rich plasma in the posterior thigth region in the previus 3 months before startin the study
