The purpose of the project is to investigate whether a history of physical training with multi-axial loading e.g. soccer is associated with increased tibia mechanical strength and if a stronger tibia developed in soccer is resilient with load carriage. The first aim of the study is to examine the effect of past multi-axial physical training on tibia bone strength. The second aim is to examine whether a stronger tibia from past multi-axial physical training will exhibit less deformation during incremental load carriage. The third aim is to examine the relationship between tibia bone quality and the level of bone deformation during load carriage. 20 recreational female soccer players and 20 age, height, and weight matched sedentary women were recruited. pQCT were performed at various tibia sites. Motion capture, ground reaction force, and electromyography were collected during load carriage. CT scans of the tibias were collected. Subject-specific musculoskeletal models and tibia finite element models were created. Multi-body dynamic simulations and finite element analysis were conducted to examine tibia deformation during incremental load carriage. Within this final report, information concerning adherence to work objectives, research progress is presented.
