Tibial Stress During Running Following A Repeated Calf‐Raise Protocol, Hannah M. Rice, Megan Kenny, Matthew A. Ellison, Jon Fulford, Stacey A. Meardon, Timothy R. Derrick, Joseph Hamill 2020 University of Exeter

Tibial Stress During Running Following A Repeated Calf‐Raise Protocol, Hannah M. Rice, Megan Kenny, Matthew A. Ellison, Jon Fulford, Stacey A. Meardon, Timothy R. Derrick, Joseph Hamill

Kinesiology Publications

Abstract Tibial stress fractures are a problematic injury amongst runners. Increased loading of the tibia has been observed following prolonged weight‐bearing activity and is suggested to be the result of reduced activity of the plantar flexor muscles. The musculature that spans the tibia contributes to bending of the bone and influences the magnitude of stress on the tibia during running. Participant‐specific models of the tibia can be used as a non‐invasive estimate of tibial stress. This study aimed to quantify tibial stress during running using participant‐specific bone geometry and to compare tibial stress before and after ...
