This is a new study from my PhD student, Igor Sancho. He looks at strength, psychological and other factors that may be different between health runners and runners with Achilles tendinopathy. Seated calf raise 6RM seems to be the strongest predictor of having Achilles tendinopathy. Some interesting other findings and clinical implications.
