Systematic Review Stiffness as a Risk Factor for Achilles Tendon Injury in Running Athletes
Anna V. Lorimer , Patria A. Hume Sports Medicine; 18 May 2016
"the link between lower body stiffness and Achilles injury. High stiffness is potentially associated with risk factors for Achilles tendon injuries ..... Large amounts of high-intensity or high-speed work or running on soft surfaces such as sand may increase Achilles injury risk. "
Is sand a 'soft surface'? If so then the body would have an increased stiffness in response; I thought bone injury was more likely than soft-tissue in lower extremities with increased stiffness, mark

The thickness is a sign of normal healing in achilles and plantar fascia. But, it is also a sign that the achilles or plantar fascia has felt a need to heal. In the individuals with thicker achilles tendons, their normal achilles were subjected to stress that required thickened to occur. Usually that stress is painful at times, sometimes not if gradual enough. Most patients who come in with a slightly thicker achilles on one side have a story to tell about the time it was painful and needed treatment. Rich
