Effect of acute exercise on the levels of salivary cortisol, tumor necrosis factor-α and nitric oxide

Abstract: The aim of the present study was to assess the levels of salivary cortisol, tumor necrosis factor-alpha (TNF-alpha) and nitric oxide (NO) before, during and after acute exercise. Acute exercise was induced using a standard treadmill test with Bruce protocol in ten physically active male participants. Unstimulated saliva was collected before, during and after exercise. The levels of salivary cortisol and TNF-alpha were assessed by enzyme immunoassays. Salivary NO was determined by the Griess reagent. The result… Show more

“…Mitochondria of untrained muscles released sustained higher levels of reactive oxygen species, whereas progressive adaptation to exercise lowered the production of free radicals through abrogation of NFkB and activator protein-1 (AP-1) pathway (Brookes et al 2008). Concurrently with the modulation of the antioxidant factors there is induction of other cytoprotective factors such as chaperones or heat shock proteins (HSPs), as well as the regulation of the nuclear kappa beta (NFkB) proliferating factor, increasing synthesis of the antiinflammatory cytokine IL-10, and decreasing production of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α), IL-1, IL-6, and further reduction of inflammatory lineages of monocytes (CD14 + /CD16 + ) (Timmerman et al 2008;Czarkowska-Paczek et al 2009;Giraldo et al 2010;Rahman et al 2010;Ropelle et al 2010) in response to physical exertion. In this sense, it was observed that skeletal muscle activation of nitric oxide synthesis is dependent on heat shock protein-90 (HSP90) expression (Harris et al 2008).…”

“…[6][7][8] Previous studies have shown that acute and chronic exercise sessions elicited changes in the levels of hormones (such as cortisol and testosterone), immunological compounds (such as immunoglobulin A (IgA)) and cytokines (such as tumor necrosis factor (TNF)) in saliva from athletes. 9,10 While some studies 11,12 concluded that acute strenuous exercise causes reduced concentrations of salivary immune biomarkers and can be associated with a high incidence of upper respiratory tract infections, others 8,13,14 reported that moderate exercise enhances immune function. As-sessment of salivary immune biomarkers can indicate the effect of sports training on immune response and subsequently influence or indicate the risk of oral and respiratory infections in sportsmen and sportswomen.…”
