Research Impact: This study examines the relationship between TL and salivary biomarkers IgA, AA and cortisol during training and competition in Paralympic swimmers. Bi-weekly saliva measures were taken during three training phases – normal baseline training, intensified training and taper as well as daily saliva samples during the 10-day Rio 2016 Paralympic Games. Results demonstrated a dose-response relationship between TL and salivary biomarkers – a significant increase in all three biomarkers was observed during period of intensified training compared to baseline training concurrent with a 38.3% increase in TL. A decrease in TL during taper phase resulted in a non-significant decrease in the salivary biomarkers, however all three remained higher than baseline levels, suggesting performance in major competition induces a stress response.
