Bülent Turna, Selma Civar Yavuz, Mahmut Alp and Kenan Işıldak had this study published in 2017 by Journal of Human Sciences, 14(2), 1435-1440.

This study was carried out in order to investigate the effects of interval sprint trainings on the lactate level and the heart rate of elite swimmers.

10 licenced swimmers who regularly train at a Turkish University swimming team took part in this study, where swimming trainings were applied for a period of 8 weeks, 4 days a week and at least 120 minutes a day.

Different measurements were taken, such as height, weight, heart rate and lactate levels. The lactate measurements were carried out using the Lactate Plus lactate analyser.

Differences were found to be statistically significant after comparing the pre and post-test values resting and maximal lactate level of swimmers (p<0.05).

As a conclusion, positive improvements were observed in the swimming performances;  interval sprint trainings have a positive impact on lactate levels and heart rates.
