EFFECTS OF THE CHANGES, DUE TO SWIMMING, IN THE BODY WATER BALANCE ON SWIMMING PERFORMANCE

Öz

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. 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. 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 style increased. 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.

YÜZMENİN NEDEN OLDUĞU VÜCUT SIVI DENGESİNDEKİ DEĞİŞİMLERİN YÜZME PERFORMANSINA ETKİSİ

Öz

Yapılan bu araştırmanın amacı; yüzme antrenmanları boyunca sıvı kaybedilip kaybedilmediğini ve eğer sıvı kaybediliyorsa performansa etkilerinin nasıl olduğunun cevabını bulmaktır. Yüzmenin neden olduğu vücut sıvı dengesindeki değişimlerin yüzme performansına etkileri konulu çalışmaya, Türkiye Şampiyonası sonucunda kendi yaş gruplarında ilk 5 içerisinde yer alan 15 kız (Myaş:15.0, SD:0.84) ve 15 erkek (Myaş:15.73, SD:1.10) toplam 30 yüzücü (Myaş:15.36, SD:1.03) gönüllü olarak katılmıştır. Yüzücülerin spor yaşları spor yaşı 8±1.16 yıldır. Her iki cinsiyette de her branştan (kelebek, sırtüstü, kurbağalama, serbest ve karışık) 3’er yüzücü bulunmaktadır. Çalışmada, kan hematokrit değeri, idrar yoğunluğu, toplam vücut sıvı yüzdesi, vücut ağırlığı ve 50m serbest yüzme performansı ölçümleri yapılmıştır. Çalışmamızdan elde edilen verilerin analizinde SPSS 15.0 programı (Lisans No: 9888978) kullanılmış ve kesim noktası tüm istatistiksel analizlerde 0.05 olarak alınmıştır. Su takviyesiz yapılan antrenman sonrasında, her iki cinsiyette de, hematokrit değerinin ve idrar yoğunluğunun arttığı (p<0.05), vücut ağırlığının ve toplam vücut sıvı yüzdesinin azaldığı (p<0.05) gözlemlenmiş ve 50m serbest yüzme performansında bir değişiklik bulunamamıştır. Fakat su tüketilen antrenman sonrasında, yüzücülerin 50m serbest yüzme performanslarında iyileşme gözlemlenmiştir (p<0.05). Su içerisinde yapıldığı için sıvı kaybının olduğu düşünülmediği yüzme sporunda, antrenman sırasında sıvı tüketiminin performansı etkilediği belirlenmiştir. Özellikle, yarışma öncesinde yapılan antrenmanlar sırasında tüketilen sıvı, yarışma performansını doğrudan etkileyeceğinden, yarışmada alınacak sonuçlar açısından sıvı tüketimi çok fazla önem taşımaktadır
