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.
