Investigating The Effectiveness And Benefits Of A 3d Printed Ladder For Rat Resistance Training Compared To A Previously Published Model, Raghav D. Sharma
International Journal of Exercise Science: Conference Proceedings
PURPOSE: To document and assess the training of rats using a new design and 3D printed ladder. The results were compared to the same rats climbing a ladder which is similar to ladders used in the majority of previous research. The rungs of the previous ladder were in the shape of a cylinder whereas the new model had rectangular flat steps. Rats were expected to exhibit different biomechanics while climbing the two different ladder models. In the new model we expected rats to use plant and push climbing (PPC) where rats put their entire foot on the step and push …

Accelerated Skeletal And Cardiometabolic Decline In Hispanic Women Versus Stability In Men During Mid-Life, Camila Guadiana, Grecia V. Morales, Marianna Gamboa, Jose M. Moris
International Journal of Exercise Science: Conference Proceedings
Mid-life represents a critical physiological juncture where skeletal and metabolic health often diverge. While Hispanic adults are known to face elevated risks for both osteoporosis and cardiometabolic disease, the specific temporal synchronization of these declines, particularly the concurrent acceleration of bone loss and visceral adiposity, remains understudied in this population. PURPOSE: To examine sex-specific differences in body composition, bone mineral density (BMD, g/cm²), and blood pressure across three mid-life decades (40s, 50s, 60s) in Hispanic adults. METHODS: This cross-sectional study included 100 Hispanic adults (36 men and 64 women) from Laredo, TX, stratified into age groups 40-49, 50-59, …
The Effects Of Physical Activity On Bone Health In Women As They Age, Shannon A. Matthews, Deborah Rhea, Phil Esposito, Ryan Porter
The Effects Of Physical Activity On Bone Health In Women As They Age, Shannon A. Matthews, Deborah Rhea, Phil Esposito, Ryan Porter
International Journal of Exercise Science: Conference Proceedings
Osteoporosis affects one in three women over 50, often resulting in fractures that impair mobility and quality of life. Although bone mass and density decline with age, achieving higher peak values before menopause may reduce this risk. Physical activity (PA) is a modifiable factor in skeletal integrity, yet its impact across life stages remains underexplored. Since 80–90% of peak bone mass is accrued by age 16, PA during adolescence and early adulthood is critical. Few studies have examined how specific PA patterns during these periods relate to adult bone health in pre‑menopausal women. PURPOSE: To investigate the relationship between early‑life …

Beyond The Scale: Exercise Frequency Reflects Metabolic Health Independent Of Adiposity, Macilynn E. Coles, Nicole Cipriano, Diana Kolb, Ross Moody, Martin R. Lindley, Sarah Deemer
International Journal of Exercise Science: Conference Proceedings
Physical activity (PA) is an important determinant of metabolic health, yet individuals with similar body mass can differ in metabolic function. Frequency of aerobic (AT) and/or strength training (ST) may differentiate metabolically healthy from unhealthy individuals, independent of body composition. PURPOSE: To compare AT and ST frequency among metabolically healthy lean (MHL), and metabolically healthy (MHO) and metabolically unhealthy (MUO) adults with obesity. METHODS: 59 men and women arrived at the Applied Physiology Lab following an overnight fast (0700h-0900h). Metabolic health (MH) status was assessed by cardiometabolic disease (CMD) history, resting blood pressure (BP), lipid profile, and fasting and 2h …
Fatigue-Matched Three Different Squats Elicit Blood Lactate Responses In Young Adults, Jiwon Song, Kase Pennartz, Wonjae Lee, Sarah Deemer, Jakob Vingren, David Church, Joshua L. Keller
Fatigue-Matched Three Different Squats Elicit Blood Lactate Responses In Young Adults, Jiwon Song, Kase Pennartz, Wonjae Lee, Sarah Deemer, Jakob Vingren, David Church, Joshua L. Keller
International Journal of Exercise Science: Conference Proceedings
Resistance exercise (RE) with blood flow restriction (BFR) promotes muscle hypertrophy, using low external loads and may also improve cognitive function and neuroplasticity, possibly by increasing brain-derived neurotrophic factor (BDNF). Lactate accumulation during exercise has been proposed as a potential mediator of exercise-induced increases in BDNF. However, it is unclear whether different RE loading strategies or BFR under fatigue-matched conditions produce distinct lactate responses that could differentially influence downstream neurotrophic mechanisms. PURPOSE: This study examined blood lactate responses for high-load (HL), low-load (LL), and LL-BFR RE in recreationally active young adults. METHODS: Sixteen healthy, recreationally active young adults …
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 …

Agreement Of Skeletal Muscle Mass Estimates Between Professional And Consumer-Grade Bioelectrical Impedance Analysis, Julia A. Whitson, Carina M. Velasquez, Christine M. Florez, Ainsley E. Way, Madison H. Sullivan, Reva Ann Rudolph, John Alexander, Adhirath Malladi, Grant M. Tinsley
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 …
Muscle Excitation And Prefrontal Cortex Oxygenation Responses During Resistance Exercise, Kase J. Pennartz, Jeremiah Blough, Wonjae Lee, Jiwon Song, Myungjin Jung, Joshua L. Keller
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 …

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 …

Enhancing Dispositional Mindfulness And Emotion Regulation In Youth Athletes Via A Breathwork And Visualization Intervention, Imare Tasby, Louis Hein, Rene Barbier, Kenia Gonzalez, Mei-Jing Ang, Sven Hoekstra, Kelvin Wu
International Journal of Exercise Science: Conference Proceedings
Competitive youth sports impose significant psychological demands, often leading to stress and maladaptive emotional regulation. Dispositional mindfulness protects against burnout, yet practical interventions for youth athletes are scarce. Breathwork and visualization offer a physiological gateway to emotional control, but their efficacy in this population is unclear. PURPOSE: This study examined the efficacy of a 12-week breathwork and visualization intervention on dispositional mindfulness and emotion regulation strategies (cognitive reappraisal vs. expressive suppression) in adolescent soccer players. METHODS: Twenty-seven athletes were initially recruited from Soccer Central San Antonio. Following 5 dropouts (1 intervention, 4 control), a final sample of 22 participants …
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
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 …

However, the influence of the type of practice approach on intrinsic motivation among softball pitchers when they learn new pitches is less clear. PURPOSE: To compare intrinsic motivation in adolescent softball pitchers following a practice session using two different practice approaches. METHODS: Fifty adolescent-aged softball pitchers seeking to obtain a breaking pitch (drop ball) were randomly assigned into two practice designs, each with the same goal-directed behavior of “creating as much downward vertical break on the ball as possible.” One group practiced using a …
Sex Differences In Pre-Cooling Effect On Cognitive Processing Changes During Exercise In The Heat, Kristin N. Grabow, Amber M. Shipherd, Meral N. Culver, Christopher M. Hearon
Sex Differences In Pre-Cooling Effect On Cognitive Processing Changes During Exercise In The Heat, Kristin N. Grabow, Amber M. Shipherd, Meral N. Culver, Christopher M. Hearon
International Journal of Exercise Science: Conference Proceedings
Cognitive processing (CP) declines during exercise are greater in the heat, but precooling (PC) prior to exercise in the heat can attenuate this decline. While males (M) and females (F) do not differ with regard to the impact of PC on thermoregulatory variables during exercise in the heat, F do demonstrate better perceptional values than M when using PC prior to exercise in the heat. Thus, if perceptional values potentially impact CP during exercise in the heat, then the PC impact on that response could differ between M and F. PURPOSE: The purpose of this study was to compare sex …

The Effects Of Multiple Circuit Training Sessions In Hot Compared To Thermoneutral Environmental Conditions On Environmental Symptomology, Jenna King, Ryan Dunn, Alexandra Brojanac, Mario Hernandez, Yasuki Sekiguchi
International Journal of Exercise Science: Conference Proceedings
Heat acclimation (HA) protocols have been under constant development since the 20th century, with the optimal HA approach yet to be determined. Adaptations from traditional approaches likely favor aerobic performance due to the nature of low- to moderate-intensity, endurance-based exercise in the heat. However, individuals involved in team sports, military personnel, and occupational workers may benefit from adaptations induced by a HA protocol that is more sport-/activity-specific. PURPOSE: To investigate differences in environmental symptomatology during a circuit training session in the heat (35°C; 40% relative humidity [RH]) following short-term (5 day) circuit training in hot and thermoneutral environmental conditions. METHODS: …
