Impulse Variability Following Increased Running Speed

increasing running speeds are associated with impulse variability and will lead to increasing impulse. The purpose of this study was to investigate about the impulse variability following velocity increase.

28 elite runners (body mass: 69.63 ± 6.670 kg), (age: 34.75 ±6.626 years) and (Height: 175.96 ± 6.74 cm), participated in the present study, voluntarily. The force data were measured with a sampling frequency of 300 Hz while running on a treadmill by a force plate, then the impulse and mean impulse variables were extracted. Analysis of Variances with repeated measurements with a significant level (p <0.05) was used to analyze the data.

These results showed that with increasing velocity in the Impulse stance phase, there is a significant difference between the velocities of 3.5 and 4.5 m / s and increasing the velocity from 3.5 m / s to 4.5 m / s. Increases.

It seems that a change in running speed causes a change in the momentum of the running support phase and increases with increasing impulse speed.
