Abstract

Aim: One of the particular
sources of oxidative stress is smoking and thiobarbituric acid reactive
substances (TBARS) and malondialdehyde (MDA) have been used as biomarkers of lipid
peroxidation of oxidative damage. Therefore, we aimed to investigate the acute
effect of moderate exercise on oxidative stress by determining serum MDA levels
by TBARS in moderate smoker subjects versus non-smokers.

Material & Methods: Fifty
healthy subjects performing moderate intensity exercise were assigned to 2
groups as moderate smokers (11-20 cigarettes/day) (Group Smoker, n=25) and
non-smokers (Group Non-Smoker, n=25). Venous blood samples were collected from
all participants half an hour before exercise (pre-exercise) and immediately
after exercise (post-exercise) to determine MDA levels as an indicator of lipid
peroxidation in the serum by TBARS/UV (ultra violet).

Results: Although no significant
differences were observed in pre-exercise MDA levels between the groups,
post-exercise MDA levels in smokers were significantly higher than that of
non-smokers (p<0.05).

Conclusion: The MDA
determination in serum by TBARS/UV appears to be positively correlated with
smoking status in particularly female subjects. Therefore, it can be a promising
helpful tool in demonstrating the oxidative stress due to moderate exercise
particularly in smokers to reorganize a healthier life style.

Sigara içen ve içmeyen bireylerde orta derecede egzersizin oksidatif stres üzerine akut etkileri

Abstract

Amaç:  Oksidatif stresin esas kaynaklarından biri sigara içilmesidir ve tiyobarbitürik asit reaktif türevleri (TBRAT) ve malondialdehit (MDA) oksidatif hasarın biyobelirteci olarak kullanılmıştır. Bu nedenle sigara içen ve içmeyen bireylerde TBART ile serumda MDA seviyelerini belirleyerek orta derecede egzerzisin akut etkilerini araştırmayı amaçladık.

Gereç ve Yöntemler: Orta derecede egzersiz yapan ve orta derecede sigara içen (11-20 sigara/gün)(Grup Sigara İçen, n=25) ve hiç sigara içmeyen (Grup Hiç Sigara İçmeyen, n=25) 50 sağlıklı birey iki gruba ayrıldı. Tüm bireylerden egzersizden yarım saat önce ve egzersizden hemen sonra TBART/UV ile serumda lipid peroksidasyonu indikatörü olarak MDA seviyelerini belirlemek için venöz kan örnekleri alındı. 

Bulgular: Gruplar arasında egzersiz öncesi MDA seviyelerinde anlamlı değişiklik olmamasına rağmen sigara içenlerde egzersiz sonrası MDA seviyeleri, sigara içmeyenlerden istatistiksel olarak anlamlı şekilde yüksek bulundu (p<0.05).

Sonuç: TBART/UV ile serumda MDA seviyelerinin belirlenmesi, özellikle kadın bireylerde sigara içilmesiyle pozitif ilişki göstermektedir. Bu nedenle özellikle sigara içenlerde daha sağlıklı bir hayat tarzını organize etmek için orta derecede egzersize bağlı oksidatif stresin gösterilmesinde ümit vaad eden yararlı bir araç olabilir.
