Objective: The purpose of this study, it has been aimed to find an answer to the question whether
liquid is lost throughout these trainings and if it is, what are its effects on one’s performance.
Methods: Totally 30 swimmers (age:15.36±1.03 year), 15 girls (age:15.0±0.84 year) and 15 boys
(age:15.73±1.10 year), who ranked first five in their age group in Turkey championship, have taken
part voluntarily in the study whose topic is “Effects of the changes, due to swimming, in the body
water balance on swimming performance”. Years of experience of the swimmers are 8±1.16 year.
Either sex group is composed of three swimmers of each style (butterfly, breaststroke, backstroke, free
style and medley). Within the study, the measurements of blood hematocrit value, urine density, total
body water percentage, body weight and 50m free style performance have been made. In the analyses
of the data provided by our study, SPSS 15 program has been used and a cut of point in all the
statistical analyses has been taken as 0.05.
Findings: After the trainings which are done without water reinforcement, it has been observed that
for either sex, hematocrit value and urine density increased (p<0.05), body weight and total body
water percentage decreased (p<0.05) and the performance in 50m free style remained the same.
However, after the trainings with water intake, it has been observed that the performance in 50m free
Results: Regarding swimming that is not considered to cause water loss as being performed in water,
it has been determined that the water intake affects the performance. As the water that is consumed
during the trainings which are done prior to a competition directly affects the race performance, water
consumption is critically important as to the rankings.
