Resumo:
The dissertation aimed to analyze the transmission of impact of three different models of a military boot through its influence on tibial acceleration. The variable peak acceleration, and the intensities of the signal in certain frequency bands, were measured on the vertical axis using accelerometer, in order to characterize the boots suitability as ergonomic and biomechanics tool for the military. Ten (10) subjects walked on a treadmill at constant and standard speed, barefoot and with three different shoes. The variables were measured using a capacitive accelerometer fixed to the skin on the tibia and the procedure reevaluated on two different days. The values found showed excellent reliability. The average reduction in peak impact measured in the tibia of the subjects using the boots was near 50 per cent, as compared to the barefoot. After analysis of the average peak acceleration, the results were not conclusive as to the significant difference in shock absorption between the types of boots. Studying the acceleration data in conjunction with assessments of intensities of frequency bands of the transmission of impact, it seems that the common buskin had the best result. There is a need for further studies with other equipment, such as instrumented shoe insoles and force platforms, for more precise characterization of the military boots as well as testing of mechanical properties after shoe degradation cycles.
