Abstract
Bu çalışma, egzersizde flavonoidler ve serbest radikaller ile ilişkisini araştırmak amacıyla yapılmıştır. Araştırmada, 8 haftalık, 174-211 g ağırlığında toplamda 28 adet sağlıklı erkek Wistar Albino cinsi rat kullanılmıştır. Ratlar, kontrol (n=7), kara mürver (n=7), egzersiz (n=7) ve kara mürver + egzersiz (n=7) grubu olarak rastgele 4 gruba ayrılmıştır. Kontrol grubundaki ratlara herhangi bir müdahale uygulanmazken, egzersiz grubu ve kara mürver + egzersiz grubundaki ratlara, 5 gün boyunca adaptasyon sürecinde 10 m/dk hızında 15 dk boyunca egzersize adaptasyonları sağlanmıştır. Adaptasyon sürecinin ardından, 3 hafta boyunca haftada 5 gün, 20 m/dk hızında ve 30 dk boyunca treadmill egzersiz protokolü uygulanarak oksidatif stres indüklenmiş ve kara mürver grubunda bulunan ratlara kara mürver takviyesi, 400 mg/kg/gün dozunda, 3 hafta boyunca intragastrik gavaj yöntemiyle uygulanmıştır. Toplamda 28 gün süren araştırmanın sonunda, tüm hayvanlar genel anestezi altında enjektör yardımıyla intrakardiyak yöntem kullanılarak sakrifiye edilmiş ve kan örnekleri toplanmıştır. Alınan kan örneklerinin Glutatyon (GSH), Katalaz (CAT), İleri Oksidasyon Protein Ürünleri (AOPP) ve Malondialdehit (MDA) biyokimyasal analizleri, ELISA yöntemiyle kit prosedürlerine uygun bir şekilde çalışılmıştır. Verilerin analizinde R Studio programı kullanılmış ve p<0,05 istatistiksel olarak anlamlı fark kabul edilmiştir. Çalışmamızda kullandığımız görsellerin tasarımı, Inkscape programı kullanılarak oluşturulmuştur. Yapmış olduğumuz istatistiksel analizler sonucunda, CAT, MDA ve AOPP düzeylerinde anlamlı bir farklılık bulunmazken (p>0,05), GSH düzeylerinde anlamlı bir farklılık tespit edilmiştir. Bu farklılık, kontrol ve egzersiz grupları arasında olup, egzersiz protokolünün GSH düzeylerini anlamlı düzeyde azalttığı ve oksidatif stres düzeylerini artırdığı belirlenmiştir (p<0,05). İstatistiksel olarak gruplarda anlamlı bir farklılık olmasa da, grup içi ortalama değerler incelendiğinde, uyguladığımız egzersiz protokolü ile birlikte kontrol gruplarına kıyasla oksidatif stresin yükseldiği ve bu yükselen oksidatif stresin kara mürver + egzersiz gruplarında nispeten az da olsa inhibe edildiği gözlemlenmiştir. Sonuç olarak, kara mürver (Sambucus nigra L.) takviyesinin, egzersizle birlikte yükselen oksidatif stresi baskılayabileceği ve sporcu beslenmesinde oksidatif stresin etkilerini azaltmada önemli bir rol oynayabileceği söylenebilir.
This study was conducted to investigate the relationship between flavonoids and free radicals in exercise. In the study, a total of 28 male Wistar Albino rats, weighing 174-211 g and aged 8 weeks, were used. The rats were randomly divided into 4 groups: control (n=7), black elderberry (Sambucus nigra L.) (n=7), exercise (n=7), and black elderberry + exercise (n=7). No intervention was applied to the rats in the control group, while the rats in the exercise and black elderberry + exercise groups underwent a 5 day adaptation period with a 15 minute exercise at a speed of 10 m/min. After the adaptation period, oxidative stress was induced by applying a treadmill exercise protocol at a speed of 20 m/min for 30 minutes, 5 days a week, for 3 weeks. Black elderberry supplementation was administered at a dose of 400 mg/kg/day to the rats in the black elderberry group via intragastric gavage for 3 weeks. At the end of the 28 day study, all animals were sacrificed under general anesthesia using an intraj cardiac method with a syringe, and blood samples were collected. The biochemical analyses of Glutathione (GSH), Catalase (CAT), Advanced Oxidation Protein Products (AOPP), and Malondialdehyde (MDA) in the collected blood samples were performed using the ELISA method in accordance with the kit procedures. Data analysis was conducted using the R Studio program, and p<0.05 was considered a statistically significant difference. The designs of the visuals used in our study were created using the Inkscape program. As a result of the statistical analyses conducted, no significant differences were found in the levels of CAT, MDA, and AOPP (p>0.05), whereas a significant difference was observed in GSH levels. This difference was between the control and exercise groups, with the exercise protocol significantly reducing GSH levels and increasing oxidative stress levels (p<0.05). Although no significant difference was observed statistically between the groups, when examining the intra-group mean values, it was observed that oxidative stress increased with the applied exercise protocol compared to the control groups, and this elevated oxidative stress was relatively inhibited, albeit slightly, in the elderberry + exercise groups. Consequently, it can be stated that elderberry (Sambucus nigra L.) supplementation may suppress oxidative stress elevated by exercise and play a significant role in reducing the effects of oxidative stress in athlete nutrition.
