Resumen
[EN] The aims of the current study were to compare the pacing patterns of all-time 800 m,
1500 m and mile running world records (WRs) and to determine whether differences exist between
sexes, and if 800 m and 1500 m WRs were broken during championship or meet races. Overall
and lap times for men and women’s 800 m, 1500 m, and mile WRs from World Athletics were
collected when available and subsequently compared. A fast initial 200 m segment and a decrease
in speed throughout was found during 800 m WRs. Accordingly, the first 200 m and 400 m were
faster than the last 200 m and 400 m, respectively (p < 0.001, 0.77 ≤ ES ≤ 1.86). The first 400 m
and 409 m for 1500 m and mile WRs, respectively, were faster than the second lap (p < 0.001,
0.74 ≤ ES ≤ 1.46). The third 400 m lap was slower than the last 300 m lap and 400 m lap for
1500 m and mile WRs, respectively (p < 0.001, 0.48 ≤ ES ≤ 1.09). No relevant sex-based differences
in pacing strategy were found in any event. However, the first 409 m lap was faster than the last
400 m lap for men but not for women during mile WRs. Women achieved a greater % of WRs than
men during championships (80% vs. 45.83% in the 800 m, and 63.63% vs. 31.58% in the 1500 m,
respectively). In conclusion, positive, reverse J-shaped and U-shaped pacing profiles were used to
break 800 m, men’s mile and 1500 m, and women’s mile WRs, respectively. WRs are more prone to
be broken during championships by women than men.
