Patellar tendinopathy is one of the most common injuries in jumping athletes. Changes in mechanical and physiological properties of tendon are the two proposed forms of pathogenesis. The efficacy of eccentric exercise when applied alone and combined with extrocoporeal shockwave therapy had been reported; however, the underlying treatment mechanisms of pain and dysfunction are not clear. This project aimed to explore the mechanical, physiological and therapeutic effects of eccentric exercise when applied as a single treatment and as an adjunct to extracorporeal shockwave therapy.

Inclusion Criteria:

• Competitive athletes
• Pain at the inferior pole of the patella with training for at least 3 months
• Tenderness at the inferior pole of the patella on palpation

Exclusion Criteria:

• Patellofemoral pain syndrome, fat pad irritations, meniscus injury, osteoarthritis, rheumatoid arthritis or infections
• History of fracture over lower limbs and inflammatory myopathies
• Cortisone injuection and other interventions within 3 months
• Contraindication to extracorporeal shockwave therapy
