Heel strike running was found to increase the risk for an Achilles injury by causing excessive heel motions that increases bending strain and rotational stress on the tendon as compared with forefoot running.
One reason heel strike running is bad for the Achilles is that at heel strike, greater compressive impact is loaded through the tendon which was found to initiate degreeatniove changes to the tendon as compared with forefoot running.
Since forefoot strike running is associated with greater Achilles tendon force compared to heel strike running, it is assumed that Achilles injuries are common running injuries suffered by forefoot runners.
Defining running related insertional Achilles tendinopathy, how its caused and to and no to treat it!
The Achilles tendon function in forefoot running is to absorb impact and store energy –both of which are impaired in heel strike running.
How heel strike running increases the risk of Achilles tendon repetitive strain injury as compared with forefoot strike running.
An inflamed Achilles tendon after running could mean that there are errors in your running form, particularly at the foot strike level.
