International Journal of Exercise Science: Conference Proceedings

Type 2 Diabetes (T2D) is associated with chronic inflammation, which can contribute to impaired satellite cells (SC) myogenic state that may result in muscle atrophy. Geranylgeraniol (GGOH) has shown to prevent muscle atrophy, reduce inflammatory markers, and increase SC content; however, the effect of GGOH on SC myogenic state in T2D rats is not known. PURPOSE: To examine the effects of GGOH on SC myogenic state and muscle cross-sectional area (CSA) in T2D rats. METHODS: 21 Sprague-Dawley rats were fed a control diet (CON; n=7), a high-fat diet with 35 mg/kg of streptozotocin (HFD; n=7), and HFD with 800mg/kg …

Morning Versus Afternoon Body Mass In Free-Living Or Controlled Euhydration, Madi M. Pomroy, Marcos Keefe, Nigel Jiwan, Jan-Joseph S. Rolloque, Casey Appell, Courteney L. Benjamin, Hui-Ying Luk, Yasuki Sekiguchi

International Journal of Exercise Science: Conference Proceedings

The standard protocol to assess hydration status is by measuring body mass in the early morning without controlling fluid intake. However, obtaining first-morning body mass is not necessarily feasible for many situations, for example, most physical activities take place in the afternoon. Thus, first-morning body mass might not be practical to assess hydration status. PURPOSE: To investigate first-morning body mass versus afternoon body mass in free- living and controlled euhydration. METHODS: 9 males (age: 21 ± 2; mass: 79.7 ± 17.8 kg) and 5 females (age: 22 ± 2; mass: 60.5 ± 13.6 kg) visited the laboratory in …

International Journal of Exercise Science: Conference Proceedings

Many dietary supplements are marketed with gendered terms, such as “for her” and “for him.” However, whether these statements reflect different nutrient contents of products and a biological basis has not been systematically examined. PURPOSE: The purpose of this analysis was to compare the micronutrient content of dietary supplements that are sold in separate forms based on gendered marketing. METHODS: The National Institutes of Health Dietary Supplements Label Database (DSLD) was searched using gendered terms, such as “hers,” “her,” “women,” “his,” “him,” and “men.” Eighty-nine pairs of micronutrient-containing products that were commercially available as a women’s version and a men’s …

Skeletal Muscle Desaturation During Moderate And Severe Intensity Cycling Exercise Is Related To Half-Time From The Reactive Hyperemia Response, Jacob R. Dellinger, Joaquin Gonzales

International Journal of Exercise Science: Conference Proceedings

Reactive hyperemia responses are a common method for assessing peripheral microvascular function, and the half-time reperfusion response, in particular, has been shown to be highly reproducible and sensitive to vascular dysfunction associated with disease. It is unclear, however, whether this parameter also provides information about microvascular responses during exercise. PURPOSE: The aim of this study was to determine the relationship between reactive hyperemia half-time response and the change in skeletal muscle oxygenation during cycling exercise. METHODS: Thirty young adults (20 men, 10 women; Age: 23 ± 5 y; peak VO₂: 35.4 ± 4.4 ml/kg/min) completed a …

The Effects Of Heat Acclimatization, Heat Acclimation, And Intermittent Heat Training On Maximal Oxygen Uptake, Ryan A. Dunn, Lauren A. Fry, Yasuki Sekiguchi, Courteney L. Benjamin, Ciara N. Manning, Robert A. Huggins, Rebecca L. Stearns, Douglas J. Casa

International Journal of Exercise Science: Conference Proceedings

Maximal oxygen uptake (VO_2max) is an important determinant of endurance performance. Heat acclimation/acclimatization (HA/HAz) strategies elicit improvements in endurance performance. When heat exposure is reduced, intermittent heat training (IHT) is potentially beneficial to alleviate HA/HAz adaptation decay, however corresponding VO_2max responses are unknown. PURPOSE: To determine the effects of HA/HAz and IHT on VO_2max in endurance runners and identify how long VO_2max adaptations remain following removal of repeated heat exposure. METHODS: Twenty-seven male endurance runners (mean ± SD; age, 36 ± 12 years; body mass, 73.03 ± 8.97 kg; height, 178.81 ± 6.39 cm; VO …

International Journal of Exercise Science: Conference Proceedings

A substantial portion of the world’s population may be inadequately hydrated, and dehydration is associated with several disease states and acute impairments in exercise performance. As such, there is continued interest in novel strategies to promote adequate hydration. The carbohydrate alpha-cyclodextrin has recently been shown to enhance water uptake through human aquaporins expressed in a single-cell model and promote longevity in model multicellular organisms. However, there is no relevant human research examining the potential hydrating effects of alpha-cyclodextrin-containing beverages. PURPOSE: To determine if novel beverage formulations containing alpha-cyclodextrin improve a bioimpedance-based hydration marker in humans. METHODS: In a …

Body Fat Percentage And Hormonal Intrauterine Device Use Are Independently Associated With Self-Reported Menstrual Regularity In Young Adult Females, Gabrielle Dehaven, Madelin R. Siedler, Christian Rodriguez, Sarah White, Alex Brojanac, Ethan Tinoco, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

Menstrual regularity is a key indicator of energy availability, long-term bone density, and other important health information in females. The occurrence of a regular menstrual cycle indicates that an individual’s level of estrogen is supportive of strong bones and that they are achieving the caloric intake required to support their activity level. In contrast, an irregular menstrual cycle can be indicative of insufficient energy availability which may, over time, result in low bone mineral density and thus a higher risk of bone stress injuries. However, hormonal contraceptive use, including the rising use of intrauterine devices (IUDs), may mask these changes …

Relationships Between Morning And Afternoon Wut (Weight, Urine Color, And Thirst) Criteria And Hydration Markers, Marcos S. Keefe, Jan-Joseph S. Rolloque, Nigel C. Jiwan, Casey R. Appell, Tyler Mccollum, Hui-Ying Luk, Yasuki Sekiguchi

International Journal of Exercise Science: Conference Proceedings

A Venn diagram decision tool consisting of weight, urine color, and thirst (WUT) is suggested to measure hydration status. The WUT Venn diagram has been used as a practical hydration status assessment tool; however, this relationship has only been investigated using a first-morning urine sample. PURPOSE: To investigate relationships between morning and afternoon WUT criteria, blood and urine markers. METHODS: Eight men (age: 21 ± 3; mass: 76.3 ± 15.6 kg) and five women (age: 22 ± 2; mass: 60.5 ± 13.6 kg) completed the study. Body mass, urine color, urine specific gravity (USG), urine osmolality (U_{OSM …}

Reliability And Relationships Between Supine Medicine Ball Throw Kinetics And Vertical Jump Height, Evan B. Johnson, Pratibha S. Maurya, Kayla P. Sisneros, Ty B. Palmer

International Journal of Exercise Science: Conference Proceedings

Supine medicine ball throw (SMBT) assessments have been used previously to evaluate upper-body explosive strength in young adults. Kinetic variables, such as peak force and rate of force development (RFD), can be measured during a SMBT. These variables have been suggested to be important predictors of athletic performance capacities. However, limited data exist regarding the reliability of SMBT peak force and RFD measurements and how they associate with performance during a vertical jump (VJ) test. PURPOSE: The purpose of this study was to examine the reliability of SMBT variables and their relationship with VJ height. METHODS: Twenty young, …

Physiological Stress Responses To A Live-Fire Training Evolution In Career Firefighters, Drew E. Gonzalez, Sarah E. Johnson, Courtney C. Dillard, Ryan J. Sowinski, Steven E. Martin, Lisa C. Colvin, Matthew J. Mcallister

International Journal of Exercise Science: Conference Proceedings

Firefighters have a physically demanding job that exposes them to many specific and unique stressors, which contribute to cardiovascular disease (CVD) risk (i.e., cardiovascular strain, inflammation, and oxidative stress) or even mortality. At present, the literature lacks data evaluating these physiological stress responses amongst firefighters in any realistic or simulated scenarios, such as a live-fire training evolution (LFTE). Given the elevated risk of premature mortality, there is a critical need to better understand the physiological stress responses to an LFTE. This information could aid in developing nutritional, training, and other various interventions to mitigate stress load and reduce the incidence …
