"* Load magnitude: A dumbbell as heavy as possible within the given repetitions and sets.~* Number of repetitions: week 1: 15 reps, Week 2-3: 12 reps, Week 4-5: 10 reps, Week 6-8: 8 reps, Week 9-12: 6 reps~* Number of sets: 3~* Rest between sets: 2 - 3 min.~* Number of exercise interventions: 2~* Duration of experimental period: 12 weeks~* Fractional and temporal distribution of the contraction modes per repetition and duration of one repetition: 3s concentric, 2s isometric: while change concentric/eccentric phase, 3s eccentric.~* Rest in-between repetitions: No~* Range of motion: Full range of motion~* Intervention frequency: 3 times a week, with minimum 48 h recovery time in-between."

Two thousand impulses of shock waves are applied to the painful tendon, with a pressure between 1.5 and 3.0 bar (depending on what the patient tolerates). We use a power hand piece that provides energy of 0.01-0.35 mJ/mm2

Information and advice are based on assessment and will comprise the standardized oral and written information. Participants will be educated regarding pain during and after activities and encouraged to be physically active. With only one session, there is great reliance on self-management. Thus, information and advice are made available through a handout.
