The Relationship Between Shoulder Mobility And Upper Body Muscle Mass On 2-Rm Bench Press Performance, Raquel J. Cavazos, Francesca Aquilino, Ernesto Balderrama, Chaehyun Byun, Shelby Gerner, Cheyenne Martinez, Austin Riffe, Vipa Bernhardt, Michael D. Oldham

International Journal of Exercise Science: Conference Proceedings

INTRODUCTION: Upper body strength is one of the most important factors in American football and thus tested frequently. However, strength may come at the cost of mobility as recent studies have reported an inverse relationship between shoulder range of motion (ROM) and strength, with an increase in strength causing a decrease in ROM (Shitara et al., 2022). PURPOSE: The purpose of this study was to determine if upper body muscle mass or shoulder mobility are associated with two-repetition max (2-RM) bench press performance in collegiate football players. METHODS: Data from 80 Division I varsity football players (20.5 ± 1.4 …

Intermuscular Emg Coherence Between Shoulder Muscles During Fatigue In Older Adults With And Without Rotator Cuff Disease, Xinyu Li, Huiying Zhu, Lisa Griffin

International Journal of Exercise Science: Conference Proceedings

The risk of degenerative rotator cuff disease (RCD) increases with age, partly due to changes in neuromuscular control, especially during fatiguing contractions. Intermuscular electromyographic (EMG) coherence, reflecting shared neural inputs between motor neuron pools, is essential for maintaining shoulder joint stability. PURPOSE: To determine differences in EMG coherence within the rotator cuff muscles, and between the rotator cuff and deltoid muscles, during sustained isometric fatiguing contractions in older adults with and without RCD. METHODS: Thirteen older adults with RCD (68 ± 8 yrs) and 20 without RCD (69 ± 8yrs) participated. Intramuscular EMG was recorded from the supraspinatus …

Sleep Duration Is Increased Following Muscle Damaging Exercise In Hot Environmental Conditions, Marcos Keefe, Ryan A. Dunn, Casey R. Appell, Nigel C. Jiwan, Jan-Joseph S. Rolloque, Hui-Ying Luk, Yasuki Sekiguchi

International Journal of Exercise Science: Conference Proceedings

Sleep and recovery measures are typically negatively affected by a muscle-damaging bout of exercise. However, it remains unknown if the additive effects of hot environmental conditions, resulting in increased core temperature and other thermoregulatory responses during the exercise bout, further progress changes in quantity and performance quality of sleep duration. PURPOSE: To investigate the effect of muscle-damaging exercise in the heat, compared to a thermoneutral condition, on sleep and recovery measures. METHODS: Ten healthy males (age: 23 ± 3yr; body mass: 78.7 ± 11.5kg; height: 176.9 ± 5cm; lactate threshold [LT]: 9.7 ± 1.0km^.hr^-1) performed two …

Effect Of Bungee Unweighting On Vo2, Heart Rate, Rpe, And Body Weight While Walking, Jaelynn Barrera, Ariel Perez, John D. Smith

International Journal of Exercise Science: Conference Proceedings

Unweighting systems are commonly used for rehabilitation and training purposes, and can alter energy expenditure, pain perception, and joint stress.

Hemodynamic Responses To Blood Flow Restriction Exercise With Different Types Of Cuffs, Lin-Sheng Chen, Philippe Brosselin Perez Palma, Natalie Mclaurin, Daniela Charry Segura, Francisco Aguilar, Hirofumi Tanaka

International Journal of Exercise Science: Conference Proceedings

While blood flow restriction (BFR) training has gained popularity, the original narrow elastic (NE) design featured in the Kaatsu bands has been gradually replaced by wide-rigid (WR) nylon blood pressure cuffs that are cheaper and easily available. We demonstrated that using WR cuffs resulted in marked increases in blood pressure and myocardial oxygen demand during BFR walking exercise compared with NE bands. Currently, the hemodynamic responses to BFR resistance exercise using different types of cuffs are unknown. PURPOSE: To compare blood pressure and physiological responses before and after BFR resistance exercise with WR cuffs and NE bands. METHODS: …

Alternating Muscle Activation Patterns Across The Deltoid Muscles During Sustained Fatiguing Contractions, Ningzhen Zhao, Xin Yu, Lisa Griffin

International Journal of Exercise Science: Conference Proceedings

Alternating muscle activation (AMA) across synergists has been identified in lower-extremity muscles that may function to prolong force output during sustained contractions; however, this has not yet been identified in upper extremity muscles. AMA consists of two periods: co-activation (Co-A), in which a pair of synergists are simultaneously increasing or decreasing EMG amplitude, and trade-off (TO), in which the EMG amplitude of one muscle is increasing while the EMG amplitude of a synergist is decreasing. We hypothesized that TO duration would increase and Co-A duration would decrease during fatigue. PURPOSE: To investigate AMA patterns during sustained submaximal isometric fatiguing …

Food Accessibility Struggles For College Students With Dietary Restrictions, Ella Schleuning

Mahurin Honors College Capstone Experience/Thesis Projects

College is a time when many students experience independence for the first time in their lives. This is the first time they have had to do their laundry on their own, keep their room clean, and maybe most importantly, they are responsible for figuring out where they are going to eat every day, for every meal. The focus of this study is on food accessibility struggles for college students, specifically looking at Western Kentucky University’s (WKU) food on-campus, as well as students with dietary restrictions.

Since college is the first-time students are responsible for their own meals, it can often …

Lipid Genetics In Pregnant Women: Maneuvering The Challenges Of Using Degraded Samples, Kylee Meece

Mahurin Honors College Capstone Experience/Thesis Projects

The results of this project will explore a novel approach to lipid metabolism in pregnant women by exploring the relationship between maternal gene expression of genes critical for fat metabolism, protein expression, and maternal and neonatal outcomes. The study will also examine gene expression in lean pregnant women compared to obese pregnant women, shedding light into the adverse pathology of obesity during pregnancy. These findings may uncover a mechanism related to gene-expression that connects unfavorable maternal fat metabolism to inflammation and/or insulin resistance, which may help to uncover future targets for interventions.

The analysis of lipid gene expression requires the …
