Aim: In this study, the effects of 4-week swimming training applied to swimmers aged 19-26 on HDL, LDL, VLDL,

cholesterol, alkaline phosphatase, protein, lactate dehydrogenase, urea and phosphorus parameters were

investigated.

Methods: . 22 swimmers with an average age of 24.5±2.46 years and a mean age of 5.12±1.1 for sports

participated in the study. A swimming training program was applied to the participants for 4 weeks/3 days. All

tests and measurements were performed before starting the 4-week training program and after completing the 4-

week program.

Results: The data obtained from the study were analyzed using the SPSS 15.0 package program. The normality

distribution of the data was made using the shapiro-wilk test. Participants' pre-post test measurements were

analyzed with the Wilcoxon signed-rank test. According to the results of the data, there was a statistically

significant difference between BW, HDL, LDL and ALP pre-post test data (p<0.05).

Conclusion: As a result, it can be said that the swimming training program applied regularly for 4 weeks can

affect the performance positively with the changes in some biochemical parameters.
