Acute Effects Of Carbon Fiber Plate Insoles On Drop-Jump Performance And Force Characteristics In Recreationally Trained Adults, Becca Henicke, Boram Lim
International Journal of Exercise Science: Conference Proceedings
Carbon fiber plate insoles (CFPI) are designed to increase footwear stiffness and may improve elastic energy utilization during human locomotion. However, most research has focused on CFPI effects in running and sprinting, particularly endurance running, with limited evidence examining their impact on plyometric performance that relies heavily on the stretch-shortening cycle (SSC), a key mechanism underlying many sports movements. Because SSC involves a rapid eccentric-to-concentric transition that stores and releases elastic energy, the drop jump provides a practical model to assess SSC efficiency with and without CFPI. PURPOSE: To examine the effects of CFPI on SSC efficiency and jump …

Does Perceived Competence And Practice Type Influence Motor Performance In Softball Pitchers Developing A New Pitch Type?, Anthony W. Fava, Matthew Miller, Emily Sauers, Gretchen Oliver
International Journal of Exercise Science: Conference Proceedings
Competence-based motivation frameworks use perceived self-confidence (PSC) to explain performance outcomes. Although PSC has been associated with improved performance on fundamental motor skills, PSC can also be task specific and may change depending on particular contexts within a sport. PURPOSE: To assess whether PSC influenced motor performance in softball pitchers developing a new pitch type under two different practice types. METHODS: Fifty adolescent-aged softball pitchers participated. Pitchers were randomly assigned into two practice types: Constraints-led Approach (CLA), (14.9±1.2y,64.8±10.1kg,1.69±0.1m), and Traditional (Trad), (14.5±1.0y, 65.4±11.4kg, 1.67±0.1m). Recruited pitchers indicated the drop ball (DB) was not their ‘go-to’ pitch nor was …

Nightly variability in sleep duration is an independent predictor of cardiovascular risk, yet the physiological mechanisms underlying this association remain unclear. Few investigations have focused on whether variability in habitual sleep duration influences autonomic and cardiovascular responses to acute stress. PURPOSE: The purpose of this study was to examine whether habitual variability in nightly sleep duration predicts autonomic and cardiovascular reactivity to acute psychosocial stress, as measured by blood pressure, heart rate, and heart rate variability (HRV) changes during the Trier Social Stress Test (TSST). We hypothesized that individuals with greater sleep duration variability would exhibit exaggerated autonomic and cardiovascular …
Effect Of Walking With Weighted Vest On Gait Mechanics And Energy Expenditure,
2026
Texas A&M University-San Antonio
Effect Of Walking With Weighted Vest On Gait Mechanics And Energy Expenditure, Nicholas Becerra, John D. Smith
International Journal of Exercise Science: Conference Proceedings
Weighted vests are used in many different types of exercises to increase difficulty/intensity. The distribution of weight matters when it comes to performance (Gerhart et al. 2020), and if weight is not distributed properly, then balance may be affected, thereby changing gait and further increasing energy expenditure. Others have also suggested increasing the load of the weighted vest can decrease pH level within the body (Martínez-Noguera, et al. 2024), however it is unclear is changes in gait are contributing to this increased effort. PURPOSE: to investigate the effect of using a weighted vest while walking on a treadmill has …

International Journal of Exercise Science: Conference Proceedings
Skeletal muscle mass (SMM) is an important body composition metric in clinical and research settings. However, criterion methods such as magnetic resonance imaging and computed tomography are largely inaccessible, so surrogate methods such as dual-energy X-ray absorptiometry (DXA) and bioelectrical impedance are used to estimate SMM. The agreement of these surrogate estimates may be impacted by physiological characteristics of the specific populations being evaluated. PURPOSE: To compare SMM estimates derived from DXA and bioimpedance methods using differing prediction equations within a sample of muscular, resistance-trained adults. METHODS: Forty participants (23 M, 17 F; [mean ± SD] age: 28.1 …

Which Sex Hormone Markers Best Predict Bone Mineral Density? A Nhanes 2013-2014 Analysis, Katarina Kozakova, Elina Satlik, Sarah E. Little-Letsinger
International Journal of Exercise Science: Conference Proceedings
Osteoporosis is a silent disease that is typically not diagnosed until after a fracture has occurred. Identifying biomarkers routinely collected by physicians can serve as a simple and effective screening approach to detect osteoporosis before debilitating fractures occur. The ratio of total estradiol to total testosterone (ET x10)/TT has been proposed as a biomarker associated with bone mineral density (BMD). To further improve predictive power, we propose a ratio of estradiol to free testosterone (ET/TF), rather than total, to account for the difference in hormone bioavailability. PURPOSE: The present analysis compares the association …

Dehydration Alters Pbmc Inflammatory Propensity That Impair Myoblast Fusion: An Ex-Vivo Approach, Casey Appell, Trinity N. Domonkos, Karina Olvera, Sarah Walper, Christian J. Hoebelheinrich, Larry Munger, Danielle Levitt, Hui-Ying Luk
International Journal of Exercise Science: Conference Proceedings
Muscle recovery from damage requires satellite cell activation to myoblasts and subsequent myoblast fusion, processes that are influenced, by immune-muscle crosstalk. In this context, the inflammatory propensity of peripheral blood mononuclear cells (PBMCs), may alter myoblast fusion. In vitro studies have shown that hyperosmotic stress alters PBMC inflammatory potency. However, the effect of dehydration (elevated plasma osmolality) on PBMC inflammatory propensity, and its impact on myoblast fusion is unknown. PURPOSE: To determine the effect of dehydration following muscle damage on PBMC inflammatory propensity to alter myoblast fusion using an ex-vivo model. METHODS: Active men (n=4, 19±1yr, 173.4±7.6cm, 84.3±11.6kg) …

International Journal of Exercise Science: Conference Proceedings
Following eccentric exercise-induced muscle damage, knee extensor strength is substantially reduced but typically recovers toward baseline within 48-72 hours in healthy adults. Previous studies have not determined whether hydration status influences recovery following muscle damage, despite evidence that a 46.4% of university students are dehydrated, and 59% with inadequate water intake. Suggesting a high likelihood of suboptimal hydration at baseline. Although dehydration has been shown to negatively impact force production, its influence on post-exercise damage remains unclear. However, it is unclear whether dehydration alters the recovery of force production following muscle-damaging exercise. PURPOSE: To determine the effect of dehydration …
