Achilles Tendinopathy
Anyone who runs knows a little bit about or has heard of Achilles tendinopathy. It is a frustrating over-load induced injury. Different factors contribute to tendinopathy. The site of irritation may be a clue, as insertional tendinopathy is commonly viewed as a compressive overload injury where midportion is viewed as a tensile overload injury. Although there is some evidence to suggest plantaris may have a compressive effect in mid portion Achilles tendinopathy (source). Traditionally both midportion and insertional were treated the same way. New research has highlighted the possible differences (source). With that come different loading strategies.
