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.

Study Groups

Control

The program is performed 2 times per week using resistance equipment in a physiotherapy clinic. Each session consists of on 2-legged loaded exercises for hamstring, quadriceps, gluteus maximun and core. The patients complete 3 or 4 sets in each exercise with a 2- to 3-minute rest between sets and a 5-minute rest period between the 4 exercises.

The number of repetitions decreases, and load gradually increases, every week. The repetitions and loads are as follows: 3 set of 12-repetition maximum (12RM), in week 1 and 2; 3 set of 10 RM, in week 3 and 4; 4 set of 10RM, in weeks 5 and 6; and 4 set of 8RM, in weeks 7 to 8.

Group Type: EXPERIMENTAL

Exercises program for hamstring architecture and function

Intervention Type: BEHAVIORAL

To assess the effectiveness of the inertial flywheel resistance program in the architecture and function of the hamstrings post structural hamstring injury

Intervention

Experimental: Inertial flywheel resistance training The program is performed 2 times per week using resistance equipment in a physiotherapy clinical. Inertial flywheel resistance is a type of strength training; which is based on the increasing demands on eccentric action (breaking) after a concentric action (acceleration), due to the inertial load caused during the return movement. The patients complete 16 repetition maximum (RM) with moment inertia 0.05 m² from week 1-2, 24 repetition maximum (RM) with moment inertia = 0.10 m² from week 3 to 4. 32 repetition maximum (RM) with moment inertia = 0.10 m² from week 5 to 6 and 32 repetition maximum (RM) with moment inertia = 0.13 m² in a flywheel hamstring curl devise.
