Comparison of Ground Reaction Force Components during Running with Running Shoes and Control Shoes in Individuals with Genu Varum

Running poses an essential role in maintaining cardiovascular health. However, it has been demonstrated that 2.5 to 38 injuries per 1,000 hours of running can occur. The purpose of this study was to investigate ground reaction forces components during running with running shoes compared to control shoes in individuals with genu varum.

This study was laboratory and semi-experimental. The statistical society includes all male students at the University of Mohaghegh Ardabili. The subjects of the study consist of 15 healthy males and 14 males with genu varum. Ground reaction force components were recorded using Bertec force plate during running in four conditions: barefoot, running shoes (Alborz shoes and agility shoes), and control shoes. Two ways ANOVA with repeated measure was used for statistical analyses.

Peak lateral ground reaction force at heel contact with Alborz shoes were higher than that of control shoes (P = 0.001). Peak anterior ground reaction force component at the push-off phase with agility shoes were lower than those in control shoes (P < 0.003) and barefoot (P < 0.019) condition.

Since Alborz shoes were able to reduce the peak lateral ground reaction force, using these shoes was recommended to reduce injuries. However, further study in this field is warranted.
