PURPOSE
– Analyze pacing patterns by medalists and nonmedalists in international competitive 400-m swim and 1500-m run finals
METHODS:
(1) Split times collected from 48 swimming finalists (four 100-m laps) and 60 running finalists (4 laps) in international competitions from 2004 to 2012
(2) Lap speeds were normalized to whole-race speed and compared to identify variations of pace between groups of medalists and nonmedalists
(3) Lap-speed variations relative to the gold medalist were compared for the whole field
RESULTS
(1) In 400-m swimming the medalist group demonstrated greater variation in speed than the nonmedalist group, being relatively faster in the final lap (moderate effect) and slower in laps 1 (moderate effect) and 2 (moderate effect)
(2) There were greater variations of pace in the 1500-m running medalist group than in the nonmedalist group, with a relatively faster final lap (moderate effect) and slower second lap (small effect)
(3) Swimming gold medalists were relatively faster than all other finalists in lap 4
(4) Running gold medalists were relatively faster than the 5th- to 12th-placed athletes in the final lap
CONCLUSIONS
(1) Athletes who win medals in 1500-m running and 400-m swimming competitions show different pacing patterns than nonmedalists
(2) End-spurt-speed increases are greater with medalists, who demonstrate a slower relative speed in the early part of races but a faster speed during the final part of races
