Enhancing Mental Toughness In Student-Athletes During The Covid-19 Pandemic Via Educational-Based Psychological Skills Training: Preliminary Results Of A Pilot Study, Madison Giuliani, Grant Morgan, Richard G. Cowden, Jeff S. Forsse, Andreas Stamatis Dr.

International Journal of Exercise Science: Conference Proceedings

One group of measures against the COVID-19 pandemic have been the non-pharmaceutical interventions (NPIs). NPIs taken by the NCAA included suspension of athletic seasons. Suspended championships during the pandemic have decimated the world of sports and led to changes in athletic role identity and social connectedness, which negatively affected student-athletes’ mental health (MH). One psychological characteristic that has the potential to support the MH and well-being of athletes is mental toughness (MT). MT is associated with successful sport performance and positive MH outcomes. Although empirical evidence supports the effectiveness of educational-based psychological skills training (PST) in promoting MH, similar effects …

An Extended Period Of Carbohydrate Mouth Rinsing Prior To Consumption Has No Additive Benefit On Cycling Performance, Henry D. Gebhardt, Eric J. Jones, Dustin P. Joubert

International Journal of Exercise Science: Conference Proceedings

Due to limited glycogen stores, carbohydrate (CHO) consumption during exercise is effective at improving performance in endurance events lasting longer than 90 minutes in duration. Recent research has established that CHO mouth rinsing may improve performance over shorter durations, independent of actual consumption. However, research is lacking in determining if an extended period of mouth rinsing has any additive benefit in conjunction with typical CHO beverage consumption over longer competition durations, where CHO ingestion/consumption is likely warranted. PURPOSE: Determine the effects of CHO mouth rinsing combined with consumption compared to CHO consumption alone on cycling performance. METHODS: Following …

International Journal of Exercise Science: Conference Proceedings

Mental toughness (MT) is a personal, state-like capacity that facilitates the initiation and continuation of goal-directed activities in several domains, including sports. Sport coaches are key agents in positions of authority. Coaching philosophy has been identified as one of the key parts in the development of environments that promote MT. The Coach Orientation Questionnaire (COQ) groups coaches in six profiles (Traditional, Technological, Innovative, Collaborative, Communicator, and Confrontational) mostly based on their professional training, personality, and experience. Coaches’ levels of MT and coaching COQ profiles have not been investigated together. PURPOSE: To explore the relationship between the COQ coaching profiles …

Influence Of Diet On Metabolic Physiology In People With And Without A Family History Of Type 2 Diabetes, Smaran Marupudi, Yu Lun Tai, Gabriel Figueroa, Saraswathy Nair, Jimmy Gonzalez, Emily Cisneros, Ryan D. Russell

International Journal of Exercise Science: Conference Proceedings

Type 2 diabetes (T2D) prevalence in the Rio Grande Valley is ~27% versus the 9% national average. Simply having a family history (FH+) of type 2 diabetes (T2D) increases T2D prevalence by ~40 over those with no family history (FH-). We have shown that FH+ display early markers of cardiometabolic impairment vs FH-, such as blunted microvascular reactivity, and impaired metabolic flexibility. What is not yet known is the degree to which environment vs genetics may contribute to these impairments. PURPOSE: This pilot study seeks to examine normal dietary patterns between FH groups to identify potential patterns in macro- and …

Acylated And Unacylated Ghrelin Impact On Protein Synthesis And Signaling Pathways Of L6 Myotubes, Colleen L. Oreilly, Selina Uranga, James D. Fluckey

International Journal of Exercise Science: Conference Proceedings

Ghrelin has recently become a hormone of interest in the fight against type two diabetes. Ghrelin is found in two forms (acylated vs. unacylated), with the acylated form of ghrelin being cited as diabetogenic purportedly due to its interaction with growth hormone secretion. Both the Acylated Ghrelin (AG) and Unacylated Ghrelin (UAG) forms are reported to have metabolic functions within skeletal muscle, despite having little expression of the only known ghrelin receptor known as the growth hormone secretagogue receptor 1a (ghsr-1a). The investigation into AG and UAG on skeletal muscle in type 2 diabetes (T2D) shows promise; however, the measures …
