Sex Differences In Force Production During Static And Dynamic Round-Offs In Tumblers, Molly M. Scheidt, Autum Andrusick, Amy Fugiel, Megan Goodyear, Amber M. Chelette
International Journal of Exercise Science: Conference Proceedings
A roundoff is an acrobatic tumbling skill performed in gymnastics, dance, or cheer, consisting of a preparatory phase, an action phase, and a landing phase requiring coordinated movements between the major joints and muscles. A dynamic roundoff is expected to produce a greater force than a static roundoff, as the running start increases velocity and allows for greater momentum and power generation through the landing. Additionally, differences in force production between males and females may be present due to differences in body mass, body composition, and strength. PURPOSE: The purpose of this study was to determine if gender played …
Exercise-Induced Metabolic Demand Modifies Nirs-Based Assessments Of Reactive Hyperemia, Elizabeth G. Knoll, Wonjae Lee, Joshua L. Keller
Exercise-Induced Metabolic Demand Modifies Nirs-Based Assessments Of Reactive Hyperemia, Elizabeth G. Knoll, Wonjae Lee, Joshua L. Keller
International Journal of Exercise Science: Conference Proceedings
Combining near-infrared spectroscopy (NIRS) with a vascular occlusion test (VOT) is commonly used to assess the determinants of reactive hyperemia. However, the influence of exercise-induced metabolic demand on NIRS-derived outcomes remains unclear. Because reactive hyperemia is governed by redundant endothelial, myogenic, and metabolic factors, incorporating non-fatiguing exercise may provide an experimental approach to differentially emphasize their relative contributions. PURPOSE: Therefore, our purpose was to examine the effects of submaximal exercise on NIRS+VOT indices of skeletal muscle tissue oxygenation (StO2). METHOD: Twelve healthy adults ranging from 18 to 35 years old (6 males and 6 females; 25 ± 6 years; 72.7 …

International Journal of Exercise Science: Conference Proceedings
Skeletal muscle mass (SMM) is a useful variable for evaluating overall fitness and detecting conditions like sarcopenia and cachexia. While several validated laboratory and clinical devices (including magnetic resonance imaging, dual-energy X-ray absorptiometry, and laboratory-grade bioimpedance devices) are adept at SMM assessment, such measures may prove inaccessible or cost-prohibitive to the average person. Consumer-grade bioimpedance analyzers seek to bridge this gap and provide affordable, accurate body composition information. PURPOSE: The purpose of this study was to compare the validity of skeletal muscle mass (SMM) assessment by a consumer-available hand-to-foot bioimpedance analyzer between females and males, using a professional-grade device as …

Hand-To-Foot Consumer-Grade Bioelectrical Impedance Shows Better Accuracy Than A Foot-To-Foot Analyzer, Madison H. Sullivan, Ainsley Way, Carina M. Velasquez, Christine M. Florez, Julia Whitson, John Alexander, Adhirath Malladi, Grant M. Tinsley
International Journal of Exercise Science: Conference Proceedings
Multi-frequency bioelectrical impedance analysis (MFBIA) is a widely available and noninvasive method used in body composition analysis. Tanita is a well-defined company that produces many MFBIA devices, ranging from consumer- to professional-grade. Tanita MFBIA devices use either hand-to-foot or foot-to-foot electrode arrangements, which may lead to different results for components such as body fat percentage (BFP). With MFBIA becoming more common and available, it is important to determine the accuracy of these different hardware configurations of MFBIA analyzers. PURPOSE: The purpose of this study was to compare two consumer-grade MFBIA devices differing in electrode arrangement to a laboratory-grade MFBIA …

Influence Of Moderate-To-Vigorous Physical Activity During Physical Education For Fitness, Cognition, And School Day Activity In Adolescence, Grant Dunn, Jessica Pegg, Kevin Dames, Samantha Moss
International Journal of Exercise Science: Conference Proceedings
In Texas, students K-12 are required to engage in moderate-to-vigorous physical activity (MVPA) at least 50% of the time spent in physical education (Texas Education Code § 28.002, 2021). Engaging in MVPA advances developmental outcomes, including health-related fitness and cognition, to support long-term health behaviors. However, there is a lack of evidence examining if the MVPA requirement is being met and possible health impacts. PURPOSE: 1) Identify how many students adhere to the MVPA physical education requirement and 2) investigate differences in developmental outcomes (i.e., health-related fitness [upper and lower body strength], cognition), and school day MVPA and sedentary behavior …

Muscle Excitation And Prefrontal Cortex Oxygenation Responses During Resistance Exercise, Kase J. Pennartz, Jeremiah Blough, Wonjae Lee, Jiwon Song, Myungjin Jung, Joshua L. Keller
International Journal of Exercise Science: Conference Proceedings
Resistance exercise (RE) enhances cognitive function potentially through increases in cerebral blood flow and oxygenation (O2Hb). These exercise-induced changes in cerebral blood flow and concomitant neural activity reflect the neurovascular coupling. Blood flow restriction (BFR) combined with low-load (LL) RE is an effective tool for increasing muscle excitation, size, and strength. However, the effects of BFR RE on cerebral oxygenation responses remain unknown. PURPOSE: Therefore, our purpose was to compare the effects of LL, LL + BFR, or (high-load) HL volume-equated squats on changes in prefrontal cortex (PFC) oxygenation and muscle excitation in adults. METHODS: Thirty healthy, young …

Accumlated Thermal And Cardiovascular Load Are Unaffected By Sauna Bathing Timing Relative To Exercise, Isabel J. Richardson, Marcos S. Keefe, Tyler B. Mccollum, Alexandra P. Brojanac, Yasuki Sekiguchi
International Journal of Exercise Science: Conference Proceedings
Sauna bathing is a recovery strategy driven by increased thermal load and can be used before or after exercise, highlighting the need to understand how thermal load relates to exercise timing. However, accompanyingcardiovascular load may compromise physiological benefits, warranting investigation into sauna timing to identify an optimal balance between thermal and cardiovascular load. PURPOSE: Examine differences in thermal and cardiovascular load across different timing strategies of sauna bathing relative to exercise. METHODS: 8 recreationally active participants (males: n = 7; females; n = 1; age: 29 ± 5 years; body mass: 72.5 ± 7.1 kg; height: 174.3 ± 7.7 cm) …
Sex-Specific Responses In Sleep Metrics Throughout Heat Acclimation In Highly Trained Endurance Runners, Sophia Waller, Marcos S. Keefe, Tyler B. Mccollum, Ryan A. Dunn, Yasuki Sekiguchi
Sex-Specific Responses In Sleep Metrics Throughout Heat Acclimation In Highly Trained Endurance Runners, Sophia Waller, Marcos S. Keefe, Tyler B. Mccollum, Ryan A. Dunn, Yasuki Sekiguchi
International Journal of Exercise Science: Conference Proceedings
Training in a hot environment (heat acclimation) elicits beneficial physiological and thermoregulatory adaptations that enhance subsequent exercise in the heat; however, additional strain from exertional heat stress may negatively influence sleep duration and quality. Although sex differences in sleep have been observed relative to exercise, it remains unclear if training in the heat exacerbates sex-specific responses. PURPOSE: Investigate the effect of heat acclimation on sleep in highly trained male and female endurance runners compared to training in a temperate environment. METHODS: 17 highly trained endurance runners (males: n = 8, age, 21 ± 3 years, maximal oxygen uptake …

Muscle Excitation During Volume-Equated Squats Performed With And Without Blood Flow Restriction, Danielle Hitchens, Joshua L. Keller, Kase Pennartz, Wonjae Lee, Jeremiah Blough, Myungjin Jung, Jiwon Song
International Journal of Exercise Science: Conference Proceedings
Blood flow restriction (BFR) resistance training has gained increasing attention in clinical, athletic, and recreational settings. It has been proposed that low-load resistance exercise combined with BFR can elicit significant muscle adaptations, potentially mimicking the effects of high-load training. Despite the growing use of this modality, the effects of BFR on muscle excitation remain incompletely understood., Surface electromyography (EMG) provides a useful approach for examining these responses. Additionally, volume-matched exercise conditions are needed to isolate the unique effects of load and BFR. PURPOSE: Therefore, the purpose of this study was to determine whether muscle excitation differs across four sets of …

The Effect Of A 12-Week Breathwork And Visualization Intervention On Inhibitory Control And Cognitive Flexibility In Adolescent Soccer Players, Louis Hein, Jace Nicolet, Tiffany Gomez, Mei-Jing Ang, Sven Hoekstra, Kelvin C. Wu
International Journal of Exercise Science: Conference Proceedings
Cognitive inhibition and flexibility are essential for soccer performance, enabling players to adapt to dynamic environments. However, accumulated season fatigue often degrades these executive functions. The Neurovisceral Integration Model posits that prefrontal cognitive function is linked to cardiac vagal tone, suggesting that autonomic regulation may support inhibitory control. While breathwork is known to enhance autonomic regulation, its potential to preserve cognitive function in youth athletes is untested. PURPOSE: This study investigated the effects of a 12-week breathwork and visualization protocol on inhibitory control (Stroop) and cognitive flexibility (Task-Switching) in adolescent soccer players. METHODS: Athletes were recruited from Soccer Central San …

International Journal of Exercise Science: Conference Proceedings
First responders need simple, cost-effective health assessments to reduce cardiovascular disease (CVD) risk. The Body Roundness Index (BRI) has emerged as a potential tool for evaluating health over the past decade, but has not yet been used among first responder groups. PURPOSE: We compared CVD risk biomarkers across BRI quartile groups. METHODS: Archival data from annual clinical testing on 170 first responders were analyzed. The BRI was categorized into quartiles: Q1 (<3.1), Q2 (3.1-3.7), Q3 (3.7-4.6), and Q4 (>4.6). The 2013 Thomas et al. equation calculated BRI, using waist circumference (Wc) and height (Ht): BRI = 364.2 – 365.5 x √[1 – ((Wc/2π)² / …

Effect Of Voltage-Dependent Potassium Channel Antagonism On Thermal Hyperemia In Skeletal Muscle Of Humans, Ysabella I. Ruiz-Pick, Sophia G. Wagle-Babb, Asim Kichloo, Albert H. Olivencia-Yurvati, Gregory M. Dick, Steven A. Romero
International Journal of Exercise Science: Conference Proceedings
We recently identified a critical role for voltage-dependent potassium (KV) channels in pharmacological vasodilation in human skeletal muscle. However, the extent to which these findings translate to physiological vasodilation remains unknown. Acute heat exposure increases skeletal muscle blood flow, but the contribution of KV channels to this hyperemic response is unclear. PURPOSE: Therefore, the purpose of this study was to test the hypothesis that KV channel antagonism would attenuate thermal hyperemia in skeletal muscle of humans. METHODS: We utilized microdialysis to directly measure local blood flow at two sites in the vastus lateralis muscle …

Nirs-Vot Measures That Relate To Hyperemic Peak Velocity, William M. Kerr, Kase J. Pennartz, Ethan J. Hein, Justin D. Sprick, Joshua L. Keller
International Journal of Exercise Science: Conference Proceedings
Early identification of individuals at risk for future adverse cardiovascular events, such as myocardial infarction and stroke, is critical for implementing targeted interventions that preserve physical function and independence. Microvascular function has emerged as a key marker of cardiovascular risk; however, multiple techniques exist to assess reactive hyperemia. Ultrasound-derived brachial artery hyperemic peak velocity (HPV) following cuff release has previously been associated with cardiovascular outcomes, with higher velocities corresponding to a nearly 50% reduction in risk. However, it remains unclear which near-infrared spectroscopy (NIRS)–derived skeletal muscle tissue oxygenation (StO2, %) responses quantified during a vascular occlusion test (VOT) …

Exploring A Live-Streamed Audience’S Impact On Performance, Rating Of Perceived Exertion, And Social Physique Anxiety During The Ymca Bench Press Test, Daimien J. Campos, Amber M. Shipherd, Christopher M. Hearon
International Journal of Exercise Science: Conference Proceedings
The presence of an audience impacts exercise performance, rating of perceived exertion (RPE), and social physique anxiety (SPA) through self-presentation theory. Research has found physical audiences influence exercise performance, RPE, and SPA, whereas recorded digital audiences show increased SPA but no changes to performance or RPE. Given audience visibility appears necessary for these changes to occur, live-streaming platforms, an unexplored area in research, may offer a viable alternative by providing real-time viewer feedback. PURPOSE: To investigate the effects of a live-streamed audience on physically active males’ and females’ exercise performance, RPE, and SPA during a YMCA bench press test. METHODS: …

Cardiovascular disease (CVD) is the leading cause of death in the United States, and aging is a major risk factor for the development of CVD. Aging is associated with vascular inflammation and T cell accumulation, even in the absence of infection or injury. Previous studies in rodent models of hypertension and heart failure suggest that autoantigens may contribute to cardiovascular dysfunction. However, whether autoantigens inappropriately activate T cells in old mice and drive age related arterial dysfunction is unclear. PURPOSE: This study aimed to determine whether age related arterial inflammation results from antigen dependent activation, suggesting the presence of …

With increasing global temperatures and interest in sports participation, more physically active men and women are exposed to hotter temperatures. To ensure the safety of these individuals, it is essential to identify the predictors of the rate of core temperature rise. PURPOSE: To determine the predictors of the rate of core temperature rise between males and females while exercising in warm and hot environments. METHODS: Physically active eleven males (age: 23±5 yrs, body mass: 72±8 kg, height: 175±8 cm, estimated maximal oxygen uptake [VO2max]: 51.6±5.9 ml⋅kg-1⋅min-1) and six females (age: 27±8 yrs, …
