Background: The aim of the present study was to comparison of the effect of polyurethan thermoplastics military boots mileage on lower limb muscle activities during running in people with and without back pain.
Methods: The statistical population of the present study consisted of healthy men and with low back pain in Ardabil province. A statistical sample of 30 people aged 20-25 years was selected by available sampling and participated in the present study. Statistical samples were divided into two groups. There were 15 patients in the low back pain group, and the second group of 15 people as the healthy group. They received two new and used pair of boots. They were made of thermoplastic polyurethane. muscle activities of the right leg were recorded during running. Two-way ANOVA was used for statistical analysis at a significance level of 0.05.
Results: Findings showed significant main effect of boot type for rectus femoris (p=0.037 d=0.146) during loading phase and gluteus Medius (p=0.006 d=0.242) during push-off phase. Findings showed significant main effect of boot-by-group interactions for rectus femoris during mid-stance (P=0.020; d=0.161).
Conclusion: The results of this study showed that the type of boots used can be effective in preventing lower limb injuries and absorbing shock and impact in people with low back pain, on the other hand, the use of new thermoplastic polyurethane operational boots is suggested for people with low back pain. Our findings showed that the observed changes in muscle activity variables are more obvious in second-hand boots. It seems that changing boots after 6 months of heavy wearing is suitable for people.
