Abstract
Introduction.
Antioxidant system in saliva protects oral cavity as well as
gastrointestinal tract form attack of free radicals. The aim of this
research was investigating the whole antioxidant system variations in
saliva of athlete men. The effect of short term intense exercise on
salivary flow rate, superoxide dismutase (SOD) activity and uric acid
concentration was examined. Material and Method. In a
double blind randomized design, 25 healthy athlete men (mean age
22.9±1.5 years, mean weight 73.77±5.8, height 176.6±7.13m body fat
14.34±1.31% and maximum oxygen consumption 48) enrolled for the
research. Before collecting their un-stimulated saliva, the purpose of
study was explained and informed consent obtained. Their
un-stimulated whole saliva samples were collected before, immediately
after and one hour after treadmill runs at exhaustion. Activity of
antioxidant enzymes (catalase, peroxidase, superoxide dismutase) and
concentration of uric acid were determined using corresponding
biochemical assays. Results. The results showed a
significant increase in uric acid concentration and activity of enzymes
immediately after exercise. However, this increase was slowly
compensated in one hour after exhaustion. Conclusions.
Therefore, short-duration and high-intensity exercise increases the
antioxidant power of saliva for scavenging the free radicals produced
by stress from intense exercise.
Key
words:athletes, saliva, flow rate, salivary whole antioxidants.
