Efficacy of Flywheel Inertial Resistance Training in the Architecture and Function of the Hamstring

Efficacy of Flywheel Inertial Resistance Training in the Architecture and Function of the Hamstrings in Athletes with a History of Hamstring Muscle Injury

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.

Randomized controlled intervention study

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
