| Abstract: |
Takeoff and landing impulses were measured for both legs over a hurdle on both a straight-a-way and a simulated track turn in order to determine whether ground reaction force is more advantageous with a given lead leg. Measurements were to the specifications of the 3000 m steeplechase in both instances. Runners ran at 5.78 m/s, a NCAA Division I Qualifying pace, and three dimensional forces were measured using a Kistler Type 9287BA multicomponent force plate. Impulse was calculated and some evidence suggests that leading with the left leg over barriers 1 and 2 is advantageous. However, no significant advantage was measured. Additional trials should be done to provide better averages and determine whether running speed effects |
