Eccentric (as opposed to concentric) exercise training has been advocated in the treatment of Achilles tendon injury — however, the mechanism for this is not well documented
What is the possible mechanism for the beneficial effect of eccentric exercise in Achilles tendinopathy?
Subjects: Seven healthy subjects (19–41 years)(male = 4, female = 3)
Experimental procedure: All the subjects were assessed and then tested in a laboratory where changes in tendon force and length changes were determined (utilising a combination of motion analysis, force plate data, electromyographic data and real-time ultrasound data) during eccentric (ECC) and concentric (CONC) loading exercises of the Achilles tendon.
Measures of outcome: Peak tendon force (N), tendon length (change), frequency of oscillations in tendon force (inflections per cycle)
Peak tendon force and tendon length: No significant differences in peak tendon force or tendon length
