Abstract
AbstractIntroduction: Studies have shown that stress fracture is one of the most common injuries among recreational runners. The purpose of this study was to investigate the effect of two different shoe types on variables related to tibia stress fracture injury during running.Materials & Methods: Twenty fivehealthy young men (21±2.27 years old) participated in this quasi-experimental study. Subjects all ran on the force plate in barefoot, with unstable and control shoe conditions.Results: Unstable shoes increased vertical loading rate significantly compared to control shoe by 80% (p=0.001). In addition, peak passive force significantly increased in unstable shoe compared to control shoe (p<0.05)and barefoot condition (p=0.039,). However, control shoe decreased peak passive force and loading rate compared to barefoot condition (p=0.002, p=0.001, respectively).Conclusion: Using unstable shoe compared to control shoe could increase the variables related to stress fracture injuriy during stance phase of running.Keywords:  Unstable shoe - Tibia stress fracture - Running
