The purpose of this study was to investigate the differences in maximum concentration of lactic acid in the blood, heart rate and performance time on the test of 4x50m freestyle swimming on a sample of two protocols: a) one breath every 3 strokes and b) 14-15m of every 50m were swum with underwater movement of the feet without breathing and a rest with one breath every 3 strokes (apnea). The sample consisted of 15 female swimmers of the competitive level aged: 15.0 ± 1.0 years. Their basic style was the freestyle. To determine the maximum blood lactate concentration, capillary blood samples were taken in the 3rd, 5th, 7th minute and analyzed by the automatic analyzer Scout Lactate Germany. We also measured the heart rate immediately after each swimming protocol. The ANOVA showed that there were no statistically significant differences between the two protocols. Maximum lactate concentration in the protocol with apnea was 10.02 ± 3.05mmol / L and without apnea 8.9 ± 3.5mmol / L. Heart rate was 186 ± 6 and 186 ± 7 b/min respectively, and performance time 140.04 ± 8.13 and 138.73 ± 8.01sec in swimmers aged 14-16. Swimming apnea needs to be studied in a larger age sample with more variables to ascertain the effects on sprint swimming.
