Determination of Degrees of Oxidative Stress and Some Antioxidant Enzyme Activities in Basketball Players

Abstract

Objective: It is known that phsical activity is an important factor in prevention and treatments of heart diseases. It has been reported that acute exercise is a major source of free radicals formation of oxidative stress. In this study, determination of degrees of oxidative stress and some antioxidant enzyme activities in basketball players haves been aimed. Method: In this study, 14 male sportsmen who play basketball and 14 sedantery individuals have been taken into the study. The degrees of malondialdehyde (MDA) and catalase(CAT) activities and reduced glutathione(GSH) have been measured as spectrophotometric. Conclusion: Statistically significant difference between degrees of MDA, CAT and GSH of control group and basketball players has been found(p<0.05). A significant decrease in values of MDA and catalase, which is an important antioxidant enzyme activity, has come up in basketball players compared to control group, value of GSH in basketball players has been found higher than that of control group (p<0.05). Consequently, in sportsmen who take part in basketball team, an increase in GSH has been seen whereas a decrease in Catalase and MDA has occured. It can be said that reduced glutathione which has the characteristic of antioxidant enzyme is a good protector against oxidative damage in individuals who do intensive exercise. Moreover, oxidative stress can affect the etiopathogenesis of many diseases.
