Athletic Performance and Bone Stress Injuries in Collegiate Athletes
Abstract/Contents
- Abstract
- Bone stress injuries are a common athletic injury that negatively impact athletes’ performance and well-being; have a high-rate of recurrence; and may reflect poor bone health in some athletes. While many studies have looked at risk factors that modify the load applied to a bone or that modify the ability of a bone to resist load, few have looked about how performance is associated with BSI risk. This study fills that gap by looking at the association between personal-best mile and cross-country times and BSI diagnoses in a large prospective cohort of competitive runners. Student athletes (N=126) from the track and field and cross-country teams at Stanford and UCLA were followed up to 4 years via yearly physical exams and questionnaires to determine which characteristics were associated with BSI events. Analyses looking at the relationship between bone mineral density (BMD) and performance found that a minute slower best mile time was associated with a statistically significant 0.16 standard deviation higher hip BMD in men, after adjusting for known risk factors for low BMD. These analyses also found a statistically significant 0.21 standard deviation higher total body BMD in females, after adjusting for known risk factors. In BSI models for men, a slower mile time was protective against BSIs though this association did not achieve statistical significance; for females, a slower mile time increased BSI rates only after adjusting for known risk factors for low BMD (RR=2.50, p=.06). Models with cross-country times as an exposure showed no association, most likely due to the high variability of cross-country times. Higher performing runners may have reduced BMD.
