This simple study has huge implications for managing tibial stress fractures in young running athletes. The authors performed a cross-sectional study comparing differences in size, shape, and strength of the tibia, fibula, and second metatarsal shaft in 16 collegiate level cross-country runners and 16 collegiate soccer players. The authors incorporated high-resolution computed tomography and determined that compared to runners, the tibia in young soccer players was 7.5% larger and 29.4% more resistant to bending forces. The polar moment of inertia, which measures the ability of bones to tolerate bending forces, was 25% larger in the soccer players. The authors attributed the improved tibial geometry to the multi-plane stressors associated with soccer. The soccer players in this study also had enhanced structure and strength in their fibula and second metatarsals as well. The authors state “These data support calls for young female athletes to delay specialization in running and participate in multidirectional sports, like soccer, to build a more robust skeleton that is potentially more protected against bony stress injuries.”
