In this study, the effects of 8-week swimming training applied to swimmers aged 19-25 on bone alkaline

phosphatase (bALP), magnesium, calcium, Unsaturated Iron Binding Capacity (UIBC), iron and ferritin

parameters were investigated. Mean age of 23.12±5.46 years, 12 swimmers participated in the study. A

swimming training program was applied to the participants for 8 weeks/3 days. All tests and measurements were

performed before starting the 8-week training program and after the program was completed. The data obtained

from the study were analyzed using the SPSS 15.0 package program. The normality distribution of the data was

made with the shapiro-wilk test, and the pre-post-test measurements of the participants were analyzed with the

Wilcoxon signed-rank test. According to the results of the data, it was determined that there was a statistically

significant difference between the metabolic rate, iron, UIBC pre-post test data. (p<0.05). As a result, it can be

said that the 8-week swimming training program, which is applied regularly, can positively affect performance with

the changes in bone mineral metabolism.
