[Physio Explained] What can single-leg hop testing tell us about running mechanics? with Dr Matt Klein

In this episode with Dr Matt Klein, we discuss a recent paper in which he was lead author looking at the predictive relationships between propulsive single-leg horizontal hopping and running kinetics in masters runners with and without Achilles tendinopathy. We explore:

• Relationship between propulsive hopping and running mechanics
• Importance and role of a horizontal hop test
• Role of hop testing and plyometrics in return to run tests
• Role of pain in hop testing
• Importance of single leg loading for running mechanics
