Step Frequency Patterns in Elite Ultramarathon Runners

STEP FREQUENCY PATTERNS IN ELITE ULTRAMARATHON RUNNERS DURING A 100KM ROAD RACE

Team: Michigan Performance Research Laboratory

Summary: Step frequency data was collected from 20 ultramarathoners during the entirety of the 2016 IAU 100 kilometer World Championship. The step frequencies and variances were analyzed throughout the race and across the variety of running speeds to explore how fatigue and pace affect a highly trained runners’ step frequency. Future work will use Detrended Fluctuation Analysis to explore any patterns in the individual variations throughout the race.
