Resistance Training as Treatment of Achilles Tendinopathy
Heavy Slow Resistance Versus Eccentric Training in the Treatment of Achilles Tendinopathy. A Randomized Controlled Trial.

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.
