International Journal of Exercise Science: Conference Proceedings

ABSTRACT Type 2 Diabetes (T2D) has several comorbidities such as cardiovascular disease, elevated lipid profile, microvascular complications, and impaired metabolic flexibility (MF: the ability to switch substrate use upon stimulation). Further, healthy Caucasians with a family history of T2D (FH+) have impaired MF similar to T2D, suggesting impaired MF could be an early-detection tool to identify at-risk populations. Hispanics of the Rio Grande Valley have ~3x the T2D rates as the US average, and have ~79% of the people in this region are either overweight or obese. However, patterns of MF in this population have not been addressed. Purpose: The …

Exercise Mobilizes Early And Late Differentiated Cd8 T Cells Expressing A Marker Of Exhaustion, Rebekah Hunt, Mahmoud Elzayat, Emily C. Lavoy

International Journal of Exercise Science: Conference Proceedings

T cell differentiation occurs following activation of key functions, such as proliferation and cytokine production. Naïve (NA) and central memory (CM) T cells are early differentiated, whereas effector memory (EM) and RA+ effector memory cells (EMRA) are later differentiated. CD57 expression, a putative marker of exhaustion, has also been used to identify later differentiated cells, although recent data indicate CD57 can also be expressed by NA and CM. Exercise mobilizes EM and EMRA to a greater extent than NA and CM. Separately, exercise has been shown to preferentially mobilize CD57+ cells. Whether these exercise responsive CD57+ cells arise from highly …

Autophagy, But Not Proteolysis, May Aid In Muscle Protein Synthesis, Megan H. Lewis, Patrick J. Ryan, Sean T. Stanelle, Colleen L. O'Reilly, Jessica M. Cardin, James D. Fluckey

International Journal of Exercise Science: Conference Proceedings

For muscle growth to occur, protein synthesis must be greater than protein degradation. However, up to this point, anabolic pathways have garnered the brunt of investigations examining anabolic capacity with little investigation into the connectedness of catabolic signaling on these anabolic targets. PURPOSE: The purpose of this study was to elucidate the contributions of proteasomal-dependent and autophagic-dependent catabolic pathways on anabolism via analysis of fractional synthetic rates (FSR) in L6 myotubes. METHODS: Differentiated, cultured L6 myoblasts were treated with media containing 4% deuterium oxide (stable isotope label) and a corresponding pharmacological treatment (NSC 185058 [autophagic inhibitor; 100 μM], …

Athlete Perceptions Of Flavored, Menthol-Enhanced Energy Gels Ingested Prior To Running In The Heat, Roxanne M. Vogel, Christopher J. Stevens, Christian Swann, Megan L. Ross

International Journal of Exercise Science: Conference Proceedings

Thermal perception during exercise is known to influence endurance performance and the onset of fatigue. L-menthol, an organic compound derived from peppermint, evokes a cooling sensation through its action on TRPM8 channels which also respond to cold stimuli. Recent work identified that the internal application of menthol-enhanced fluids can be ergogenic during exercise in the heat. Hence, the addition of menthol to energy gels may be practical and beneficial for athletes. PURPOSE: To determine athlete acceptability and preferences for flavored energy gels with different menthol concentrations. METHODS: With a randomized, crossover, and double-blind placebo-controlled design, 27 endurance athletes …

International Journal of Exercise Science: Conference Proceedings

Hispanics of the Rio Grande Valley (RGV) have the highest rates of obesity and type 2 diabetes (T2D) in the country, conditions often associated with cardiovascular disease and increased mortality. We have previously shown that healthy people with a family history of T2D (FH+) display divergent central and peripheral hemodynamic responses postprandially vs those with no family history (FH-). Why these differences exist is unknown. PURPOSE: To identify physiological factors affecting postprandial hemodynamic responses differently between FH+ and FH- groups. METHODS: Thirty-five healthy Hispanic individuals volunteered in this study, including 17 participants with a family history of T2D …

Difference In Rate Of Perceived Exertion Between Cluster- And Traditional-Set Lower Body Resistance Training, Kayleigh M. Abbott, Tyler Frank, Kenneth Bowen, Andrew A. Wolfe, Micheal Luera, Matt Laurent

International Journal of Exercise Science: Conference Proceedings

Training variation is an integral part of strength and conditioning programming as it stimulates recovery, various adaptations, enhances athletic performance outcomes, while avoiding overtraining. The structure of set and repetition prescription is often varied to achieve desired adaptive outcomes. Cluster-set (CL), or rest-pause set, training is a method utilized to change the traditional-set (TS) and repetition structure by interrupting the repetitions with a 10-30s rest interval. Results from previous reports describe CL training as optimal for increasing training volume, lift quality, and achieves similar hormonal responses when compared to TS training. However, no studies have examined differences in perceived exertion …

International Journal of Exercise Science: Conference Proceedings

While traditional yoga programs focus on static stretching and core stability, Essentrics yoga relies more heavily on full-body stretch and strengthening regiments coupled with dynamic movements such as ceiling reaches, side-to-side bends, lunges, and side leg lifts. Through the incorporation of more dynamic movements, Essentrics yoga is thought to elicit greater improvements in overall body composition, flexibility, and balance. PURPOSE: To examine the benefits of a 6-weeks long Essentrics (dynamic) program compared to standard (static) Yoga on body composition, flexibility, and balance. METHODS: Thirty-one participants (24 females and 7 males, age = 20.4 ± 0.2yrs, and BMI = 22.58 ± …

Sex-Specific Difference Of Functional Movement Screening Scores Among Rodeo Athletes, Jessie Ramirez, Andrew A. Wolfe, Andrea Green, Meghan Younger, Gillian Braden, Justin Stanley

International Journal of Exercise Science: Conference Proceedings

Faulty movement patterns, especially in elite athletes, can lead to neuromuscular imbalances. Rodeo is an example of an injury prone sport that requires optimal muscular synergy, endurance, strength, and limb flexibility to succeed in rodeo performance. The Functional Movement Screening (FMS) test has shown validity in identifying various neuromuscular imbalances, and subsequently, scientific findings support the FMS threshold score (less ≤ 14) as valid for injury risk screening in collision and team sports, firefighters, and the tactical professions. If an athlete has a composite score of 14 or less in conjunction with a previous injury, they are 15 times more …

Cortical Activity Measured With Low-Intensity Fatiguing Contractions Of The Quadriceps Muscle Group, Emma D. Bozarth, Lyric D. Richardson, Amy E. Riera, Micheal J. Luera, Amber H. Bozer

International Journal of Exercise Science: Conference Proceedings

Modulation of force production required during exercise is regulated from various mechanisms in the central and peripheral nervous system. Fatigue is influenced by various mechanics that may hinder the ability to continuously sustain force production. The neural activation patterns of these systems can be recorded as electrical impulses using several non-invasive techniques. The ability to examine these during fatiguing exercise has provided further insight into activation patterns in the central nervous system (i.e., motor and pre-motor cortex) during sustained muscle contractions. Electroencephalography (EEG) has been recently utilized to examine changes associated with central fatigue, but limited advancements in technology for …

Effects Of Low-Intensity Fatigue On Motor Unit Firing Properties During Maximal Voluntary Isometric Contractions, Lyric Richardson, Amy Riera, Emma Bozarth, Micheal Luera

International Journal of Exercise Science: Conference Proceedings

Rehabilitation from injuries impairing the neuromuscular system is often difficult to quantify due to task specificity of the affected or immobilized limb or limbs. Often, exercise regimens with clinical practitioners are designed to progress motor performance to a capacity that reflects muscle force production to pre-injury capacity. Modulation of force production from these tasks are regulated from various mechanism in the central and peripheral nervous system. The neural activation of these systems can be recorded as electrical impulses using several non-invasive techniques. Recently, the ability to examine these during fatiguing exercise has provided further insight into activation patterns and firing …

Cardiorespiratory Coordination Among Intermediate And Novice Female Collegiate Rowers, Zoey Jackson, Michelle Etchebaster, Paula Gutiérrez, Gemma Hernández, Sergi G. Retortillo, Zacharias Papadakis

International Journal of Exercise Science: Conference Proceedings

Elite rowers present high levels of cardiorespiratory performance. Rowers’ on-water performance can be predicted by a cardiopulmonary exercise test (CPET) and related measured parameters such as maximum oxygen uptake test (VO2max), ventilation (VE), heart rate (HR), expired fraction of oxygen (FeO2) and carbon dioxide (FeCO2). However, such testing provides little information about the non-linear dynamic interactions during rowing and the qualitative synergetic reconfigurations between cardiovascular and respiratory systems to adjust to the individual rowing performance. Cardiorespiratory coordination (CRC) has been proposed as a method to measure the co-variation among cardiorespiratory variables during a CPET. PURPOSE: To measure and compare …
