Anaerobic exercise affects the saliva antioxidant/oxidant balance in high-performance pentathlon athletes

Abstract: Purpose. Investigate free radical production and antioxidant buffering in military pentathletes' saliva after their performance of a standardized, running-based anaerobic sprint test (RAST). Methods. Seven members of the Brazilian Navy pentathlon team were recruited to perform a running-based anaerobic test (~90 sec). The participants provided samples of saliva before and after the test that were analyzed for biomarkers of oxidative stress such as lipid peroxidation, total antioxidant capacity and the quantity… Show more

“…Research in this area is limited and further research is warranted. Biomarkers used previously to examine oxidative stress and antioxidant status with saliva as a biospecimen include: total antioxidant capacity, uric acid, glutathione, advanced oxidation protein products, nitric oxide, and TBARS [96,97,98,99]; such biomarkers were used both in aerobic and anaerobic exercise conditions. Measuring and assessing oxidative stress in saliva has observed conflicting results using the TBARS assay, despite its popularity.…”

“…Measuring and assessing oxidative stress in saliva has observed conflicting results using the TBARS assay, despite its popularity. The intensity of the exercise bout is the proposed culprit to this as the more intense exercise-bouts have observed significant increases in salivary TBARS [97] while less intense exercises have not [96]. The lack of sensitivity and specificity with the TBARS assay might also be cause for concern.…”

“…Alterations of mineral balance, spectrum of steroid hormones, content of immune system components, activity of some enzymes, concentration of the most important metabolism products, fluctuations of acid-base balance are described in detail in the scientific literature [4][5][6][7][8]. However, we failed to find any works devoted to the investigations of free radical oxidation processes as well as to the study of the content of primary and end products of lipid peroxidation in the oral fluid of highly qualified athletes as diagnostic markers of the oxidative stress condition and negative consequences of its alteration on the organism during physical exercises of various types.…”

“…Salivary analysis has been proposed for EOIS assessment [24] and has since been used successfully [25]. Relevant biomarkers that can be found in saliva are lipid peroxidation products, such as thiobarbituric acid reactive substances (TBARS) and MDA, as well as vitamin C. Methods and instrumentation are important factors when using saliva, as it has been unsuccessful at observing EIOS that was otherwise present in plasma [2].…”
