Overview of the therapeutic tendon loading exercise regimes used

Tendon loading exercise regimeDescription of technique
Eccentric-exercise trainingEcExSlow lengthening of a muscle-tendon unit while under load
Heavy-slow resistance trainingHSRExercises in which each repetition is performed slowly (>6 s) for both the eccentric and concentric phase. The repetition maximum is decreased over the treatment period
Medical-exercise therapyMedRXResistance training that incorporates three sets of 30 repetitions during which the therapists relies on feedback from the patient to ascertain the optimal weight. The exercise is continuously monitored and the weight increased ensuring that it remains pain free as possible
