Achilles tendon stiffness is unchanged one hour after a marathon

Achilles tendon stiffness is unchanged one hour after a marathon.

Overuse-induced injuries have been proposed as a predisposing factor for Achilles tendon (AT) ruptures. If tendons can be overloaded, their mechanical properties should change during exercise. Because there data are lacking on the effects of a single bout of long-lasting exercise on AT mechanical properties, the present study measured AT stiffness before and after a marathon. AT stiffness was d...

Achilles Tendon Repair, A Modified Technique

  Background: Wound complications following open repair for acute Achilles tendon ruptures (AATR) remain the subject of significant debate. The aim of this study is to investigate the effects of covering repaired AATR using well-nourished connective tissues (paratenon and deep fascia) to avoid complications after open repair.   Methods: In this case series study, open repair was performed for 3...

Plyometric training effects on Achilles tendon stiffness and dissipative properties.

The aim of this study was to determine the effects of 14 wk of plyometric training on mechanical properties of the Achilles tendon. Nineteen subjects were randomly assigned to trained or control group. Cross-sectional area (CSA), stiffness, and dissipation coefficient of the Achilles tendon were measured before and after the training period. In the trained group, a decrease in dissipation coeff...

Related Asymmetries in Achilles Tendon Stiffness and Ankle Mobility after Rupture

INTRODUCTION The Achilles tendon is one of the largest and strongest in the body, yet is most prone to unilateral spontaneous rupture in humans. This injury dramatically changes the tissue’s composition, which has a significant effect on its mechanical behavior [1] and presumably on ankle joint function. Earlier work has considered this particular relationship between the mechanical status and ...
