Müsabaka arası içilen maden suyunun serum elektrolit düzeylerine etkisi

Bu çalışma, müsabaka arası içilen maden suyunun serum elektrolit düzeylerinde meydana getirdiği değişikliklerin incelenmesi amacıyla yapılmıştır. Çalışmaya bölgesel liglerde oynayan 16 erkek futbolcu dâhil edilmiştir. Futbolcular deney (n=9; yaş 21.30±0.83 yıl, ağırlık 72.40±1.64 kg ve boy 178.20±0.08 cm ) ve kontrol (n=7; yaş 22.50±0.98 yıl, ağırlık 69.90±2.27 kg, boy 177.90±0.07 cm) olmak üzere iki gruba ayrılmıştır. Deney grubu maden suyu kontrol grubu su içmiştir. İçecekler Müsabakanın devre arasında ve kan alımının hemen öncesinde verilmiştir. Araştırma kapsamında sporculardan; müsabaka öncesi, müsabaka arası ve müsabakadan hemen sonra olmak üzere 3 kez ve her seferde 5 cc olacak şekilde kan alınmıştır. Alınan kan örneklerinde Sodyum (Na), Potasyum (K), Klor (Cl) parametreleri incelenmiştir. Tüm değişkenlerin tanımlayıcı istatistikleri yapıldıktan sonra ölçüm zamanının impedans ve reaktans üzerine etkisi tekrarlı ölçümlerde ANOVA ile test edilmiştir. Farkların hangi zamanlarda oluştuğu Bonferroni çoklu karşılaştırma testi, deney ve kontrol grupları arasındaki farklılıkların değerlendirilmesinde ise Independent Samples t-testi kullanılmıştır. İncelenen Sodyum, Potasyum, Klor parametrelerinin kendi aralarında, deney ve kontrol grubu karşılaştırmalarında anlamlı farklılıklar (p

The effects of the mineral water drunk during the break of the competition on the serum electrolyte levels

This study has been carried out with the aim of examining the changes of mineral water drunk during the break of the football match on the serum electrolyte levels. The study includes 16 male football players performing in the local league. The football players are divided into two as experimental (n=9; age 21.30±0.83 years, weight 72.40±1.64 kg and height 178.20±0.08 cm) and control (n=7; age 22.50±0.98 years, weight 69.90±2.27 kg, height 177.90±0.07 cm) groups. The experimental group drinks mineral water, while the control group drinks water. The beverages are drunk at the break of the football match and just before the blood samples are taken. In the scope of the study, the blood samples are taken from the players three times as before the football match, at the break of the football match and just after the football match at the amount of 5 cc at every turn. Sodium (Na), Potassium (K) and Chlorine (Cl) parameters of the blood samples taken have been analysed. After the descriptive statistics of all variables have been completed, the effects of the measurement time on impedance and reactance have been tested with ANOVA in the repeated measurements. Bonferroni multiple comparison test have been used in order to determined that at which intervals the differences are occur, and Independent Samples t-test has been used for the evaluation of the differences between Experimental and Control groups. Significant differences have been observed among Sodium, Potassium and Chlorine parameters in the comparison of Experimental and Control groups (p<0.05). When the results of our study are evaluated, it can be said that loss of electrolyte occurs depending on dehydration during the football match played at 10°C and Mineral Water drunk at 10°C during the break of the football match might be beneficial in order to maintain the electrolyte levels when compared to Natural Spring Water.
