The Effects of Dehydration Resulting from Basic Endurance Training (End-1) on Performance and Examination of Body Hydration Level on Swimmers

The purpose of this study, basic endurance training in swimming is the evaluation of the resulting dehydration and its effects on performance. 14 male swimmers from Pamukkale University Swimming Sports Clup team participated voluntarily in this study. 7 athletes took liquid supplement and 7 athletes continued to practice without liquid supplement and the same protocol were repeated after 48hours. Tanita measurements, urine specific gravity, heart rate, blood pressure, body temperature, swimming performance (100m and 400m) measurements was applied. T-test was used for the difference between the pre-test and post-test values in the group, and t-test analysis was used for the differences between the groups in the independent groups. There was no statistically significant difference between in the pre-test values of the swimmers with and without liquid supplementation (p>0.05). There was a statistically significant difference in the urine density values between in the post-test values of the swimmers with and without liquid supplementation (p
