The Effects of Increasing Running Speed on the Displacement and Velocity of the Center of Pressure

Objective:

 The aim of this study was to determine the effect of increasing running speed on the displacement and speed of the center of sole pressure.

Methods:

 For this purpose, 28 professional runners with at least 5 years of experience in athletics, from among Tehran province teams in the national league, were selected as volunteers as a sample. After completing the informed consent form, the subjects first walked at a speed of 1.2 meters per hour to get acquainted with the treadmill. Then, slowly, the speed reached 2.5 meters per second, and after 3 minutes of running at this speed, the data were recorded for about thirty seconds. The runners then ran on the treadmill at a speed of 3.5 m / s and then at a speed of 4.5 m / s. Data were collected using special markers and 3D cameras. Analysis of variance with repeated measures and Bonferroni post hoc test were also used to analyze the data.

Results:

 The results showed that increasing the running speed would have a significant effect on the displacement rate and foot pressure of runners. As the running speed increased, so did the displacement and the pressure of the sole of the foot.

Conclusion:

 The results confirm the effect of increasing running speed on the amount of movement and speed of foot pressure.
