Purpose The present study attempts to describe the post competition peak lactate profile according to the gender across all the swimming strokes and swimming distances in young swimmers.

Methods Blood samples (N=284) from the ear lobe were collected by a lactate analyzer at poolside area as quickly as possible following only their finals race. Blood samples were collected at 3 mins after race completion in a total of 39 swimmers (14 young males and 25 young females). Independent t-test was use to conducted for evaluated any differences of swimming performance between boys and girls. A three-way ANOVA was conducted that examined the effect of gender and swimming styles and swimming distance on Post competition peak lactate, heart rate and RPE and Bonferroni post hoc test was used to locate the differences. Statistical significance was set at p ≤ 0.05.

Result A higher post competition blood lactate was observed in 400m individual medley (IM) (13.39 ± 3.50 mmol•L-1) in young male swimmers and 200m butterfly (8.59 ± 3.16 mmol•L-1) in young female swimmers, respectively. There was a significant interaction (p < .05) between gender, swimming strokes and distances on post competition blood lactate particularly in young male swimmers. There were also significant interactions between gender and swimming distances and between swimming styles and distance on RPE but not heart rate after competition.

Conclusion Post competition blood lactate was significantly increased in 400 m IM and 200m butterfly events for young males and young females respectively. There were gender differences in post competition blood lactates with an interaction between swimming styles and distances.
