Abstract
The aim of this study is to determine the effects of both static and dynamic strength trainings on oxidative stress and DNA damage in elite boxers. 19 elite male boxers participated in the study. Boxers were instructed to perform strength exercises 3 days a week for 8 weeks. Blood samples were taken before exercises (resting), after the first exercise (acute) and after 8 weeks following the last exercise (chronic). MDA, SOD, GPx and 8-OHdG levels of blood were examined. Statistical analyses were carried out using the SPSS 22 for Windows. The data were found to not be distributed normally. Thus, Friedman, Wilcoxon and Mann-Whitney U tests were used. The results were evaluated using an alpha level of .05. In the dynamic strength exercise group, there was no significance at GPx, however MDA, SOD and 8-OHdG levels decreased in 8 weeks. In static strength exercise group, although there was no significance at SOD, GPx and 8-OHdG, MDA levels decreased both after a single session and in 8 weeks. In addition, significant difference was found between dynamic and static exercise groups at SOD, GPx and 8-OHdG levels in pre-exercise and at 8-OHdG levels after 8 weeks. Dynamic strength exercises with Thera-Band are effective on MDA, SOD and 8-OHdG chronically, static strength exercises are effective on MDA both acutely and chronically. Neither dynamic nor static strength exercises are not effective on GPx both acutely and chronically.
Highlights
The effects of physical activity on human organism have been revealed in many studies
superoxide dismutase (SOD) catalyzes the dismutation of superoxide (O2.-) into hydrogen peroxide (H2O2), glutathione peroxidase (GPx) catalyzes the reduction of oxidized glutathione into reduced glutathione (Michels et al 1994; Gul et al 2000; Yang et al 2002)
In this study where we investigated the effects of two different types of exercises performed with thera-band on oxidative stress and DNA damage in elite boxers, both dynamic and static exercises acutely and significantly increased MDA values
Summary
The effects of physical activity on human organism have been revealed in many studies. Exercise can cause the formation of more free radicals by increasing metabolic processes and oxygen consumption in proportion to intensity and duration (Pereirae et al 1994; Colakoglu et al 1998; Palmer et al 2003). The increase of free radicals is controlled by the antioxidants (such as catalase, superoxide dismutase, glutathione peroxidase). Malondialdehyde (MDA) is the most abundant aldehyde product, and it is one of the markers used to measure the level of oxidative stress (Papas, 1996; Eken, 2011). Both superoxide dismutase (SOD) and glutathione peroxidase (GPx) are antioxidant enzymes. This study was designed to determine the effects of dynamic and static exercises with Thera-Band® on oxidative stress and DNA damage, which is a new exercise tool
