A SIMPLE METHOD TO MEASURE EXTERNAL FORCE, POWER OUTPUT AND EFFECTIVENESS OF FORCE APPLICATION DURING SPRINT ACCELERATION
Keywords: acceleration, power output, ground reaction force, mechanical effectiveness
AbstractThe aim of this applied session was to introduce and show a recently validated simple field method to determine individual force, velocity, power output properties and effectiveness of force application onto the ground during a sprint running acceleration. This method requires the use of a radar device (or several timing gates), and models the horizontal, vertical and resultant force an athlete develops over sprint acceleration using a macroscopic inverse dynamic approach. Low differences in comparison to force plate data support the validity of this simple method to determine force-velocity relationship and maximal power output, as well as the index of effectiveness of force application onto the ground. Its validity and ease of use make it an interesting tool for sprint training and performance optimization, in a specific field context of practice.
