Plasmatic antioxidant parameters of total antioxidant capacity (A) and total bilirubin (B). 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 a significant within-group difference between baseline and immediately after intervention
