The variability of competitive performance and pacing strategies in different rounds of the 400 m and 800 m freestyle swimming races at the 2017-2024 World Swimming Championships.

ABSTRACT:

Introduction

This study aims to analyze the competitive performance and pacing strategies (PS) of medalists and non-medalists in different rounds of the 400 m and 800 m freestyle at the World Swimming Championships.

Method

The 2017-2024 World Swimming Championships and 161 elite swimmers were selected. First, intra-athlete coefficients of variability (CVs) were evaluated using linear mixed effects modeling and changes in competitive performance (Δ); second, descriptive statistics of position lap time; finally, a computer algorithm was used to obtain PS, then a two-way ANOVA was performed.

Result

(i) The PS was effective in 87.5% of the swimmers in the finals compared to the heats (CVs > 0.5%), but 73.8% of the males and 86.8% of the females showed an improvement in pe
