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 …

Effects Of Chronotype And Social Jetlag On Blood Biomarkers During Wlff 2-Week Critical Training Period, Elias M. Malek, Joseph A. Sol, Katherine Christison, Charles L. Dumke, John Quindry, Graham Mcginnis 8954626

International Journal of Exercise Science: Conference Proceedings

Chronotype, an individual's natural preference towards activity during certain times of the day, influences the interaction between one's internal circadian rhythms and the external environment. When this is disrupted, it can result in social jet lag (SJL), the misalignment between our sleep/wake schedule on work days and free days. Wildland firefighters grapple with unpredictable and intense demands of their job, making them vulnerable to the challenges posed by SJL. Their duties necessitate abrupt changes in active hours, pushing against their body's inherent circadian preferences. SJL is a behavioral trait that may alter an individual's ability to respond to high stress …

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

The effect of mild sleep restriction on cognitive functioning in young children is unclear, yet sleep loss may impact children's abilities to attend to tasks with high processing demands. In a preliminary investigation, six children (6.6 - 8.3 years of age) with normal sleep patterns performed three tasks: attention (“Oddball”), speech perception (conconant-vowel syllables) and executive function (Directional Stroop). Event-related potentials (ERP) responses were recorded before (Control) and following one-week of 1-hour per day of sleep restriction. Brain activity across all tasks following Sleep Restriction differed from activity during Control Sleep, indicating that minor sleep restriction impacts children's neurocognitive functioning.
