Abstract

Context: An exercise bout completed several hours prior to an event may improve competitive performance later that same day.

Purpose: To examine the influence of morning exercise on afternoon sprint-swimming performance.

Methods: Thirteen competitive swimmers (7 male, mean age 19 3 y; 6 female, mean age 17 3 y) completed a morning session of 1200 m of variedintensity swimming (SwimOnly), a combination of varied-intensity swimming and a resistance-exercise routine (SwimDry), or no morning exercise (NoEx). After a 6-h break, swimmers completed a 100-m time trial.

Results: Time-trial performance was faster in SwimOnly (1.6% 0.6, mean 90% confidence limit, P < .01) and SwimDry (1.7% 0.7%, P < .01) than in NoEx. Split times for the 25- to 50-m distance were faster in both SwimOnly (1.7% 1.2%, P = .02) and SwimDry (1.5% 0.8%, P = .01) than in NoEx. The first 50-m stroke rate was higher in SwimOnly (0.70 0.21 Hz, mean SD, P = .03) and SwimDry (0.69 0.18 Hz, P = .05) than in NoEx (0.64 0.16 Hz). Before the afternoon session, core (0.2C 0.1C [mean 90% confidence limit], P = .04), body (0.2C 0.1C, P = .02), and skin temperatures (0.3C 0.3C, P = .02) were higher in SwimDry than in NoEx.

Conclusions: Completion of a morning swimming session alone or together with resistance exercise can substantially enhance sprint-swimming performance completed later the same day.
