Validity Of Body Volume Estimates From A Smartphone 3-Dimensional Scanning Application, Ethan G. Tinoco, Christian Rodriguez, Madelin R. Siedler, Christian Lavalle, Christine M. Florez, Sarah White, Alexandra Brojanac, Jaylynn Rasco, Gabrielle Dehaven, Grant M. Tinsley
International Journal of Exercise Science: Conference Proceedings
Body volume (BV) indicates the total 3-dimensional (3D) space an individual occupies. BV is either used alongside body mass in density-based two-compartment models or in conjunction with other body components in multi-compartment models to estimate body composition (BC). BV estimates are typically produced by costly laboratory methods, such as hydrostatic weighing or air-displacement plethysmography (ADP). However, more accessible options are emerging. Smartphone-based 3D scanning uses the phone’s built-in camera to provide a BV estimate in a time-efficient and cost-effective manner. However, few investigations have validated this method against an accepted laboratory technique. PURPOSE: To determine the validity of BV from …

Does 24-48 Or 48-96 Promote Better Rem Sleep Within Firefighters?, Ernesto Balderrama Jr, Raquel J. Cavazos, Cheyenne Martinez, Bryan G. Meek, Hussien K. Jabai, Vipa Bernhardt, Michael D. Oldham
International Journal of Exercise Science: Conference Proceedings
A firefighter’s work schedule can be very demanding regardless if they work 24 hours followed by a 48-hour time off schedule or a 48-hour on followed by a 96-hour time off. Rapid Eye Movement (REM) sleep could be the deciding factor of how well a firefighter can perform following a certain work schedule. REM sleep is associated with the mental activity of dreaming; an individual averages 20-25% REM sleep of their total sleep time (Carskadon & Dement, 2005). REM is important for recovery because it can impact cognitive functions such as impulse control and decision making (Brunet, et al, 2020). …

The Influence Of High-Intensity Interval Exercise On Vitamin-D Concentrations In Healthy Individuals, Leroy K. Bolden, Tomas Chapman-Lopez, Ricardo Torres, Jeffery Heileson, Meena Meiyyappan, Jeff S. Forsse
International Journal of Exercise Science: Conference Proceedings
Vitamin D (VD) deficiency is one of the most common deficiencies in the world due to various factors (e.g., lack of sun exposure, dietary considerations). Currently the utilization of exercise may act as an intervention for VD deficiencies to promote increases in VD concentrations in healthy populations. This could largely be due to the loss of calcium from aerobic exercise (AE), leading to a hormonal response [(e.g., parathyroid hormone (PTH)] and the activation of cytochrome’s (e.g., CYP2R1, CYP27B1) responsible for the regulation of VD. Thus, AE may serve as an intervention to promote VD synthesis due to the impacted biological …

Machine Learning Analysis Of Chronotype And Mental Toughness In Predicting Sleepiness Among Collegiate Dancers: Preliminary Findings, Alyssa Hudson, Andreas Stamatis
International Journal of Exercise Science: Conference Proceedings
Understanding the interplay between chronotype (a trait-like characteristic denoting an individual's inherent preference for sleep and activity periods), mental toughness (MT; a state-like construct that equips individuals with the skills to endure adversity while pursuing goals), and sleepiness (a fluctuating state of propensity towards dozing off) is critical in domains where optimal performance is crucial, such as in athletics. The utilization of machine learning (ML) techniques to explore the impact of MT and chronotype on sleepiness categorization is notably scarce in collegiate dancing; thus, this approach could provide novel insights into managing dancers’ health and performance. PURPOSE: To evaluate …

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 …
