The use of eccentric resistance training as management of Achilles tendinopathy is widespread. The investigators have recently demonstrated that heavy slow resistance training was superior in the management of patellar tendinopathy.

Hypothesis: heavy slow resistance training is more effective than eccentric resistance training in the clinical management of Achilles tendinopathy.
