Leg Muscle Usage Effects on Tibial Elasticity during Running

Abstract

Tibial stress fractures (TSFs) are a substantial problem in military training, but a means of predicting their occurrence remains elusive. Bone strength is key to the resistance of TSF, but bone density, a determinant of strength, is known not to predict TSF. Elasticity is nearly as important as density in determining bone strength but has not been tested in TSF, or even studied in runners. However, clinical studies of osteoporotic patients given bisphosphonates have shown significant correlations between low elasticity and fracture incidence. These basic validation studies will determine if modulators of tibial stress, such a strike mechanics and surface incline, also modulate bone elasticity during running. Because these modulators may operate on the tibia via muscles, we have combined ultrasound characterization of tibial elasticity with MRI monitoring of muscle recruitment during a running protocol in healthy volunteers.
