We aimed to compare differences in performance and pacing variability indices between 5000 m heats and finals during major championships in men and women. Data with 100 m time resolution were used to compare overall pacing variability (standard deviation of 100 m section times, SD; and coefficient of variation, CV%) and short-term pacing variabilit...
Pacing behavior is typically described through graphical profiles and coefficient of variation (CV%) with respect to the mean speed of the race. Given that races during major championships are highly stochastic because of runners’ tactical behaviors, it may be valuable to use alternative methods to better describe and capture the occurrence of paci...
Based on comparisons to moderate continuous exercise (MICT), high-intensity interval training (HIIT) is becoming a worldwide trend in physical exercise. This raises methodological questions related to equalization of exercise dose when comparing protocols. The present scoping review aims to identify in the literature the evidence for protocol equal...
