Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Stress fractures are a common and debilitating injury for a variety of athletes however current evidence does not clearly allow easy prediction of athletes at risk for a first fracture. Animal and some preliminary human evidence suggest that assessment of bone strength, muscle size and running mechanics may be primary risk factors for stress fractures. The investigators study will help determine which, if any, of these modifiable risk factors could help identify athletes at risk for stress fracture. Competitive female distance runners will be recruited for this study. Participants will placed into a stress fracture or control group based on stress fracture history. Dual energy x-ray absorptiometry (DXA) and peripheral Quantitative Computed Tomography (pQCT) will be used to assess bone structure and strength. Running mechanics will be assessed during a 30-40 minute fatiguing run. A treadmill with an embedded force plate and high speed video will be used to assess changes in running mechanics throughout the run. The purpose of this project will be to 1. explore differences in volumetric bone mineral density (vBMD), bone geometry, and muscle cross sectional area (MCSA) using pQCT 2. explore changes in load (GRFs) and running mechanics that occur during a fatiguing run in runners with and without a history of stress fracture.
