Overview

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.

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

Outcomes

Primary Outcomes

Change in the architecture and morphology of the hamstring

Time Frame: 0 and 8 week

To assess change in architecture and morphology of the hamstring at 8 week. It will be performed by a medical specialist in diagnostic imaging with a A GE Voluson 730 Expert model ultrasound machine , with 6-12 MHz linear transducer. Panoramic images of the long portion of the biceps femoris and semitendinosus will be taken from its proximal insertion, In each muscle, muscle thickness, fascicle length, penetration angle and physiological cross-sectional area will be evaluated.

Change in Maximun eccentric strength

Time Frame: 0 and 8 week

To assess the maximum eccentric strength of hamstring in Newton (N) from basiline. It will be measured in 3 repetitions with a hand held dynamometer.

Change in Maximun isometric strength

Time Frame: 0 and 8 week

To assess change in maximum isometric strength of hamstring in Newton (N). It will be measured in 3 repetitions with a hand dynamometer at two knee flexion angles.

Change in Rate of force development

Time Frame: 0 and 8 week

To assess change in rate of force development of hamstring in N/seg at 8 week. it will be measured in 3 repetitions with a hand dynamometer at two knee flexion angles.

Secondary Outcomes

  • Maximum Hip Flexion Active Knee Extension (MHFAKE) Test(0 and 8 week)
  • Single leg bridge test. Change in resistance of hamstring(0 and 8 week)
  • Change in Oslo hamstring injury screening questionnaire(0 and 8 week)
  • Functional scale of the lower limb(In the week before the 1st session of the protocol)
  • Adverse events(week 8)
  • Adherence self-report questionnaire(week 8)
  • Change in Test of a 1RM eccentric(0 and 8 week)
