Modern sport science gives a high priority to analysis of the positive and negative aspects of the sport-specific shocks and vibrations to control the mechanical aspects of the ground contacting process. The study analyzes the footsrike-generated shock wave processes based on the treadmill tests of sport footwear. The athletes were tested with the Brule@Kyer triple-axis accelerometers fixed on the ankles and body mass centers (BMC) to obtain the following test data: time gaps between the ankle and BMC acceleration peaks; and the frequency rates of the shock waves going via the test points. The study data and analyses showed that the shock wave is normally a single-peak-shaped at low (under 5m/s) run speeds and transverse/ longitudinal-wave-shaped at high speeds. It was found that the sport footwear and running techniques should be designed to secure that the shock waves are distributed in the body so that the shock wave center/ knot is kept within the body element needed to be protected from the shocks.
