Oxidative stress parameters of plasmatic total oxidant status (A), lipid peroxidation (B), and lipid hydroperoxide (C) in erythrocytes. Measurements were assessed pre-intervention (baseline), immediately after, and 20Â min after intervention. Control intervention (preload only); 400Â N (target 400Â N thoracic SMT); 800Â N (target 800Â N thoracic SMT). SMT: posterior to anterior thoracic spinal manipulation. Values are presented as mean and standard error. Significance was set as an alpha of 0.05. * Denotes significance between baseline and immediately after the intervention. ** Denotes significance between baseline and 20Â min after intervention. *** denotes significance between 400Â N and 800Â N groups. # denotes significance between 400Â N and 800Â N groups 20Â min after intervention
