Abstract

Monitoring stride interval long-range correlations has been suggested as a method for coaches and clinicians to track changes in fatigue and injury risk. This study investigated the between-day reliability of stride interval long-range correlations during treadmill running. Stride interval long-range correlations were assessed on two occasions 1-week apart using detrended fluctuation analysis during 6 minutes of running at 11, 13 and 15 km/h. Stride interval long-range correlations demonstrated good absolute reliability (95% limits of agreement: 0.11-0.14 arbitrary units) and relative reliability (intraclass correlation coefficient: 0.74-0.87) at each running speed. The absolute reliability values reported in this study can be used by athletes, coaches and clinicians to determine real changes in stride interval long-range correlations.
