Abstract

Bu araştırmada, düzenli egzersiz yapan sporcularda ve sedanterlerde oral olarak verilen gliserolün Epinefrin ve Kortizol parametreleri üzerine etkisinin araştırılması amaçlandı. Araştırmada yaş ortalamaları 22.82 ± 1.49 yıl ve vücut ağırlığı ortalamaları 73.96 ± 9.16 kg olan Selçuk Üniversitesi Beden Eğitimi ve Spor Yüksekokulu’nda okuyan 20 sağlıklı erkek sporcu ve diğer fakültelerde okuyan 20 sağlıklı erkek öğrenci olmak üzere toplam 40 öğrenci denek olarak kullanıldı. Denekler Sedanter grup S , Gliserol takviyeli sedanter grup GS , Egzersiz grubu E , Gliserol takviyeli egzersiz grubu GE olarak 4 gruba ayrılarak. E ve GE gruplarındaki deneklere 20 gün süresince 20m mekik koşu testi uygulandı. GS ve GE grubuna dahil olan deneklere 20 gün boyunca sabah saat 10.00’ da oral olarak 1.2 g/kg dozunda gliserol takviyesi yapıldı. Bütün deneklerden egzersiz periyoduna ve gliserol takviyesine başlamadan önce kan örnekleri alındı. Ayrıca, 20 günlük gliserol takviyesi ve egzersiz periyodundan sonra tüm gruplardan ikinci kan örnekleri alındı. 20. gün sonunda alınan ikinci kan örneklerinden sonra tüm gruplara belirtilen egzersiz testi uygulandı. Egzersiz testinin bitiminden hemen sonra üçüncü kan örnekleri alındı. Egzersizden 2 saat sonra dördüncü ve 24 saat sonra beşinci kan örnekleri alındı. Alınan kan örneklerinde belirlenen serum Epinefrin ve Kortizol düzeyleri ölçüldü. Bu parametrelere ilişkin gruplar arasındaki farklılıkların önem kontrolünde Varyans Analizi yapılarak, Duncan’ın Multiple Range testi kullanıldı. Grup içi farklılıkların tespitinde ise Wilcoxon Signed Ranks testi kullanıldı. Bu çalışmada uygulanan orta şiddetteki ve submaksimal egzersizin serum epinefrin ve kortizol düzeyleri üzerine önemli p≤0.05 bir etkisinin olduğu tespit edilmiş fakat bu egzersiz protokolü ile beraber uygulanan gliserol takviyesinin, en azından bu miktar ve sürede serum epinefrin ve kortizol düzeyleri üzerine önemli bir etkisinin olmadığı söylenebilir.

SPORTSMENS AND SEDANTARY TO EFFECTS OF GLYCEROL SUPPLEMENTATION ON EPİNEPHRİNE AND CORTİSOL

Abstract

A recent scientific research aimed to explain the effects of the glycerol supplement on the levels of epinephrine and kortisole parameters of sedentary individuals and some sportsmen who exercise regularly. In the research, forty students with an average age of 22.82 ± 1.49 year and an average weight of 73.96 ± 9.16 kg, who still study at the Physical Education and Sport Collage and the other faculties, were used as subjects. Subjects were they were as follows: 1. the group of sedentary, 2. the group of sedentary supplemented with glycerol, 3. the group of exercise, 4. the group of exercise supplemented with glycerol. The test of shuttle and run of 20 meters was applied to subjects in the groups E and GE within twenty days time. Subjects of the groups GS and GE were supplemented orally with the dose of 1.2 g/kg of glycerol at ten o’clock every morning within the period of twenty days. At the same time, samples of blood were taken from all the subjects before these tests. Besides, samples of blood were taken again after the tests. At the and of this period of time, the specified exercise tests were applied to all groups after the second blood test. After the exercise test, samples of blood were taken from the subjects the third time. Then, the samples of blood were taken from them two hours after the exercises the fourth time and also twenty four hours after the same exercises the fifth time again. The levels of serum epinephrine and also cortisole parameters available were measured. Having applied Variance Analysis regarding the importance control of differences of parameters among the groups, Duncan’s test of Multiple Range was applied. In addition to that, the test of Wilcoxon Signed Ranks was used to determine the differences within every group. In the meantime, accordingly, it was clearly understood that the average submaximal exercises applied in this work had a profound P
