Abstract
The footwear and equipment worn by military personnel is important to enable them to meet the specific physical demands of the daily activities of their profession. on the other hand, the mileage of the boots is an important factor that can influence the risk of sustaining injuries during running. The aim of the present study was to compare muscle activities while running on polyurethane military boots compared to thermoplastic polyurethane in males’ individuals. Fifteen healthy males received two new pair of polyurethane and thermoplastic polyurethane military boots. They were asked to wear these shoes over 6 months. Muscle activities of the right leg were recorded during running at 3.2 run speed. Two-way ANOVA was used for statistical analysis at a significance level of 0.05. Results demonstrate significant main effect of "boots" for Gas-Med (p=0.045, η2p=0.136) muscle activities during mid-stance phase. Findings showed significant main effect of time for ST (p=0.011, η2p=0.211), and Glut-Med (p=0.032, η2p=0.154), during loading phase, TA (p=0.013, η2p=0.199), and Glut-Med (p=0.049, η2p=0.131) during mid-stance phase and Gas-Med (p=0.026, η2p=0.164), TA (p=0.016, η2p=0.190), and Glut-Med (p=0.014, η2p=0.187) during push off phase. furthermore, results show significant boot-by-time interactions for ST (p=0.017, η2p=0.188) muscle activity during push off phase. Wearing new polyurethane boots was associated with significantly less muscle activation and higher mean frequency in key running-related muscles during long-distance running. This finding suggested that wearing new polyurethane boots may improve muscle function, which could improve running performance and prevent muscle fatigue.
