摘要：The aim of this study is to investigate the effects of interval sprint trainings on lactate level and heart rate in elite swimmers. 10 licenced swimmers (5 male-5 female) participated in the study voluntarily who train regularly at the Akdeniz University Swimming Team and as individual whose mean age was 20,20±1,54 years, the mean sport age was 9,10±1,59 years, the mean height was 175,00±8,39 cm and the mean of weight was in pre-test 67,07±10,74 kg; in post-test 67,18±10,37 kg. Lactate and heart rate tests were applied to the swimmers at the beginning and end of training program that was 8 weeks, 4 days a week, at least 120 minutes a day and including interval sprints in its content. Handled datas were compared by using “Paired t Test” by SPSS 22.0 statistic programme. As a result of lactate and heart rate pre and post-test values, the differences were found to be statistically significant (p<0,05). According to the data obtained, positive improvements were observed in the swimming performances. In addition, it has been concluded that interval sprint trainings have also positive impacts on lactate levels and heart rates. We believe that our study will make positive contribution to sportive performance of swimmers as well as providing reference values for swimming coaches applying interval trainings in swimming.
