Validation Of A Non-Invasive Physiological Stress Assessment: Agreement Of Salivary And Blood Cortisol Among Firefighters, Caiti Dodge, Hunter Martaindale, Steven E. Martin, Lisa C. Colvin, Drew E. Gonzalez, Matthew J. Mcallister
International Journal of Exercise Science: Conference Proceedings
Salivary cortisol has been used as an indicator of stress exposure among tactical personnel (i.e., firefighters). Assessing cortisol concentrations, whether via blood or saliva samples, can provide valuable insight into the physiological stress load placed upon the firefighter. Cortisol levels provide a reflection of the hypothalamic-pituitary-adrenal (HPA) axis activity. Salivary cortisol is unbound and has been suggested to provide a better reflection of HPA axis activity compared to blood cortisol, which is bound to soluble corticosteroid-binding globulin. Importantly, the use of salivary biosample collection also offers a more practical and non-invasive method to assess physiological stress biomarkers when blood sample …

Alternating Muscle Activation Patterns Across The Deltoid Muscles During Sustained Fatiguing Contractions, Ningzhen Zhao, Xin Yu, Lisa Griffin
International Journal of Exercise Science: Conference Proceedings
Alternating muscle activation (AMA) across synergists has been identified in lower-extremity muscles that may function to prolong force output during sustained contractions; however, this has not yet been identified in upper extremity muscles. AMA consists of two periods: co-activation (Co-A), in which a pair of synergists are simultaneously increasing or decreasing EMG amplitude, and trade-off (TO), in which the EMG amplitude of one muscle is increasing while the EMG amplitude of a synergist is decreasing. We hypothesized that TO duration would increase and Co-A duration would decrease during fatigue. PURPOSE: To investigate AMA patterns during sustained submaximal isometric fatiguing …
