A Comparison Of Continuous And Interval Exercise On Cognition In Young Adults, Emily C. Tagesen, Lawrence W. Judge, David M. Bellar
International Journal of Exercise Science
International Journal of Exercise Science 16(5): 458-468, 2023. Exercise stimulates the production and secretion of testosterone, cortisol, and brain-derived neurotrophic factor (BDNF) and affects cognitive performance. However, the interaction of these variables is unknown. To investigate these interactions, 21 college-aged men completed two work-matched exercise protocols: continuous (CONT) exercise and an interval protocol (INT). Blood and saliva samples were collected before and after exercise to quantify BDNF, cortisol, and testosterone. Participants completed a battery of cognitive assessments after exercise. A MANOVA analysis of condition demonstrated that no domains were significantly different after CONT and INT (p > 0.05). A repeated …

Salivary Cortisol Analysis In Collegiate Female Lacrosse Athletes, Jenna L. Carter, Stephanie L. Mathews, Yvette L. Figueroa, Jennifer A. Bunn
International Journal of Exercise Science
International Journal of Exercise Science 16(6): 242-251, 2023. Cortisol is a hormone that corresponds to physiological and emotional stress. The purpose of this study was to 1) evaluate the changes in cortisol in female Division I collegiate lacrosse players (n = 15) throughout the competitive season, and 2) evaluate the correlation between cortisol and athlete wellness and workload. Salivary cortisol samples were collected weekly in the morning throughout the entirety of the 2021 competitive season (12 weeks). Subjective athlete total wellness scores and sub-scores (muscle soreness, sleep quality, fatigue, and stress) were taken on the same days. Objective total …

The Metabolic And Physiological Demands Of A Simulated Fire Ground Test Versus A Live-Fire Training Evolution In Professional Firefighters, Drew Edward Gonzalez, Hunter Waldman, Matthew J. Mcallister
International Journal of Exercise Science
International Journal of Exercise Science 16(7): 230-241, 2023. Objective: This study examined the similarities in metabolic and physiological demands of a fire ground test (FGT) and a live fire training evolution. Methods: Twenty-seven firefighters completed either a FGT (n = 13) or a live fire training evolution (n = 14). Salivary samples were collected pre, immediately post, and 30-minutes post FGT and live fire training evolution, and analyzed for cortisol, uric acid, and interleukin-1β (IL-1β). Heart rate (HR) was measured pre- and post-task. Results: Both tasks resulted in significant elevations in cortisol, IL-1β, and HR. Conclusions: Both the …
