Heavy slow resistance training
The program is performed 3 times per week using resistance equipment in a fitness center. Each session consists of three 2-legged loaded quadriceps and lower limb kinetic chain exercises. 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 3 exercises.
The number of repetitions decreases, and load gradually increases, every week. The repetitions and loads are as follows: 3 times, 15-repetition maximum (15RM ), in week 1; 3 times, 12RM , in weeks 2 to 3; 4 times, 10RM , in weeks 4 to 5; 4 times, 8RM , in weeks 6 to 8; and 4 times, 6RM , in weeks 9 to 12.
Exercises program for patellar tendinopathy
To compare the effectiveness of the inertial flywheel resistance program versus slow heavy resistance in patients with chronic patellar tendinopathy
Inertial flywheel resistance training
The program is performed 3 times per week using resistance equipment in a fitness center. 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 12 repetition máximum (RM) with moment inertia 0.05 m² from week 1-6 and 8 repetition máximum (RM) with moment inertia = 0.10 m² from week 6-12.
