The comparison of standard and local shoes on the variables related to tibia stress fracture in male student recreational runners

The aim of this study was to compare the effect of standard (Adidas) and local (Nahrein) shoes on some biomechanical variables related to tibia stress fracture in healthy male recreational runners.
Fifteen healthy men (mean age: 35±2.27 years, height: 180.93±5.39cm, and weight: 85.30±8.84kg) performed running with controlled velocity on the force plate with Adidas and Nahrein shoes. Some biomechanical variables related to tibia stress fracture as peak vertical and posterior reaction forces, loading rates of these two forces, time to peak vertical and posterior forces and total time of these forces were measured by force plate system. The t-test was used to analyze data through SPSS software v.20 (p≤0.05).
Based on the result, there was no significant difference in peak vertical and posterior reaction forces, loading rates of these two forces, time to peak posterior force and total time of vertical and posterior forces variables between two shoes (p>0.05 for all variables). However, time to peak vertical force significantly increased in Adidas shoe compared to Nahrein by 8% (p=0.01).
There was no difference between Adidas and Nahrein as standard and local shoes in some biomechanical variables related to tibia stress fracture during running. Thus, Nahrein shoe could be recommended as a shoe with proper advantage of safety, shock absorption and lower cost for recreational runners.
