While previous studies suggest that bone-loading activities benefit musculoskeletal health, many track and field (T&F) athletes suffer from bone injuries. Currently, little is known about bone characteristics between different T&F event designations which may provide key information about the etiology of injury. PURPOSE: To compare bone measures using Dual-energy X-ray Absorptiometry (DXA) between 33 T&F athletes: Sprinters (<1500 m; n=11), Distance runners (1500+ m; n=14), or those who compete in Other field events (n=8). METHODS: All athletes provided informed consent prior to completing dietary recall, sleep quality, injury, and bone-specific physical activity (BPAQ) questionnaires and total body, lumbar spine (L1-L4), and dual-hip DXA scans. RESULTS: All groups were equivalent for all lower body hip bone variables (Figure 1), diet and sleep quality, and historical BPAQ scores (all p>0.05). However, upper body bone measures of the arms, ribs, and (L1-L4) were different between the groups even after adjusting for initial differences in body mass (all post hoc p≤0.042, Figure 1) as Sprinters had greater mean arm BMC than Distance runners and those who competed in Other field events had greater (L1-L4) BMC than Distance runners. Additionally, those who ran Distance suffered 3.6x and 4.3x more bone injuries than Sprinters and Other, respectively, which was statistically trending (p=0.058). Other bone mineral density Z-Score (1.5±0.7) was significantly greater than Distance (0.3±1.2), but not Sprinters (0.6±0.2). CONCLUSION: These data suggest despite Sprinters, Distance, and Other T&F athletes being similar for recovery factors such as dietary measures, sleep quality, and historical bone loading activities, unique upper body skeletal differences emerged. Additionally, bone injury incidence wasn’t uniform across T&F event designation but this doesn’t necessarily translate to reduced Z-Scores.
