简要总结
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.

结局指标
主要结局
Change in the architecture and morphology of the hamstring
时间窗: 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
时间窗: 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
时间窗: 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
时间窗: 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.
次要结局
- 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)
