Duchenne Muscular Dystrophy, Scott Onyeokeziri, Zacharias Papadakis

International Journal of Exercise Science: Conference Proceedings

CLINCAL PRESENTATION & EXAM: Duchenne muscular dystrophy (DMD) is an inherited, neuromuscular disorder that affects approximately 1 in 5000 live male births. It is primarily characterized by muscular degeneration due to dystrophin deficiency, a protein found in muscles. There are several varieties of muscular dystrophy disorders—another common one is Becker muscular dystrophy, caused by a truncated, but partially functional DMD gene. DMD begins during childhood, with symptoms starting between 3 and 5 years of age, and it gradually progresses throughout the lifespan of an individual. The first apparent physical sign is an abnormal, waddling-like motion while walking, indication of a …

Insulin Sensitivity Effects On Peripheral Vascular Responses To Fmd In Metabolic Syndrome Women., Ariel Gomez, Klaudia Szych, Annajita A. Rubio, Shannon Jackson, Matthew A. Barlow

International Journal of Exercise Science: Conference Proceedings

Sedentary populations with obesity and metabolic syndrome (MetSyn) have presented with impaired vascular dysfunction, including vasodilation reduced 40-50%. The mechanisms of vascular endothelial dysfunction has also been associated to the bioavailability of nitric oxide levels and in metabolic compromised individuals the diminished content of endothelial NO are a prime mechanistic target for study. PURPOSE: We hypothesize that decreased reactive hyperemia observed in MetSyn compared to age matched-control patients are primarily due to mechanistic dysfunction of the eNOS pathway and lower Insulin Sensitivity Index (ISI). METHODS: 30 participants (10 MetSyn and 20 Controls) completed brachial FMD testing and vascular …

The Effect Of Sedentary Behavior On Arterial Stiffness In Healthy And Metabolic Syndrome Women, Annajita A. Rubio, Ariel Gomez, Klaudia Szych, Matthew A. Barlow

International Journal of Exercise Science: Conference Proceedings

Overweight and obese physical stature has been associated with increased endothelial dysfunction and the development of cardiovascular disease. This dysfunction may further be progressed as this population develops Metabolic Syndrome and Diabetes. To understand the mechanisms responsible for the vascular dysfunction in the Metabolic Syndrome participants in our research study, we aimed to identify if there is a difference in the Pulse Wave Velocity (PWV) as an effective measurement of peripheral arterial stiffness. Previous studies show that adults with higher superficial femoral artery stiffness experienced greater perceived fatigue and thus are less likely to continue daily physical activity. PURPOSE: …

Acute High Dietary Phosphate Consumption Impairs Macrovascular, But Not Microvascular Function In Young, Healthy Men, Brandi Y. Stephens, Jasdeep Kaur, Jennifer R. Vranish, Thales C. Barbosa, Auburn L. Johnson, Jeanette Blankenship, Paul J. Fadel

International Journal of Exercise Science: Conference Proceedings

Chronic consumption of inorganic phosphate (P_i) is associated with an increased risk of cardiovascular disease in the general population. Importantly, with the growing abundance of processed foods, dietary intake of P_i in the United States has doubled the daily-recommended amount. However, the influence of acute consumption of high P_i on the cardiovascular system is not clearly understood, with equivocal results reported. Shuto et al. demonstrated that acute consumption of high P_i results in an impairment of endothelial function in healthy subjects, whereas a recent study by Levac et al. has refuted this finding. Moreover, these …

Purpose: To investigate whether a 5-week summer school program involving physical activity has an effect on plasma glucose levels and lipid profiles among Hispanic female high school students. Methods: Thirty-three female high school students (15-17 years) from an underprivileged Hispanic area in southern Texas were randomly assigned to either an experimental group that participated in a summer school program (n=17) or a control group that did not …

Irisin Treatment During Chronic Inflammatory Bowel Disease In An Rodent Model Improves Bone Formation Rate, Anne M. Anderson, Corinne Metzger, Susan Bloomfield

International Journal of Exercise Science: Conference Proceedings

Bone is a dynamic tissue that responds to many stressors including physical stress and certain disease states. Chronic systemic inflammatory conditions, like inflammatory bowel disease (IBD), result in increased bone resorption and decreased bone formation leading to low bone mass and high fracture incidence. There currently are no effective, safe treatments for IBD. Irisin is a hormone that is released during exercise and has previously been shown to increase bone mass. PURPOSE: Determine if exogenous treatment with irisin can mitigate the inflammatory insult of chronic IBD on bone. We hypothesized that young male rats with induced IBD and treatment …

Fractional Synthetic Rate And Markers Of Protein Turnover Are Altered In The Diaphragms Of Cachectic Mice, Conner A. Benson, Nicholas P. Greene, Jacob L. Brown, Megan E. Rosa-Caldwell, Tyrone A. Washington, Richard A. Perry, Michael P. Wiggs

International Journal of Exercise Science: Conference Proceedings

Cancer cachexia, a wasting syndrome characterized by rapid skeletal muscle wasting and fat loss, directly accounts for up to 20-40% of cancer-related deaths. All muscles, including respiratory muscles, are susceptible to atrophy because cancer cachexia is a systemic disease. Atrophy of the primary breathing muscle, the diaphragm, can lead to respiratory distress, which is commonly associated with a cachectic phenotype. Indeed, the diaphragm is more susceptible to atrophy in certain conditions, but little is known about the effects of cancer-cachexia on protein turnover in the diaphragm. Therefore, investigations into the alterations in protein turnover could provide insight to the molecular …

Cardiac Vagal Tone Impairment Is Associated With Reduced Cerebral Blood Flow In Collegiate Athletes Following Concussion, Madeline N. Wainman, Justin Frantz, Benjamin Williams, Sydney H. Lyng, Tonia Sabo, Kathleen R. Bell Md, Sushmita Purkayastha

International Journal of Exercise Science: Conference Proceedings

Reduced cerebral blood flow (CBF) is linked to functional disturbances following concussion. Since cardiac vagal tone (an index of cardiac health) is associated with disturbances in the autonomic nervous system, deficits in CBF are likely associated with cardiac vagal tone impairment post-concussion. PURPOSE: The current study examined cardiac vagal tone and CBF on days 3, 21 and 90 following concussion in comparison to non-injured control athletes. The association between these two variables was also evaluated. METHODS: Concussed male and female collegiate athletes were evaluated day-3 (N=29), day-21 (N=25) and day-90 (N=17) post concussion and matched controls were enrolled (N=29). A …

Augmented Mechanoreflex In Type 2 Diabetic Rats: Piezo Channels, An Important Part Of The Puzzle?, Ann-Katrin Grotle, Yu Huo, Audrey J. Stone

International Journal of Exercise Science: Conference Proceedings

Type 2 diabetics (T2DM) have an abnormal cardiovascular response to exercise. The exercise pressor reflex, which is evoked by metabolic and mechanical stimuli arising from the contracting muscle, is a critical cardiovascular regulatory mechanism during exercise and is exaggerated in hypertension, heart failure, and peripheral artery disease. A recent study found that T2DM patients have an augmented metaboreflex. However, whether the mechanoreflex is also augmented in T2DM is not known. PURPOSE: The purpose of the study was to test whether the mechanoreflex is exaggerated in T2DM. Furthermore, we tested the contribution of mechano-gated Piezo 1 and 2 channels to …

Body position and kicking style were randomly varied between trials such that half of all trials were performed using each kicking style and each body position. A calibrated underwater camera was used to record …

Metabolic And Ventilatory Responses To Interval-Based Active And Passive Treadmill Sprinting, Robert Brown, Nichole Gadd, Jared Dalpe, Timothy Carter, Caylon Rogers, Terry L. Dupler, William E. Amonette

International Journal of Exercise Science: Conference Proceedings

Historically, exercise scientists and practitioners believed that continuous, steady exercise at a single moderate intensity was most beneficial for health, but recent findings suggests that higher intensity interval training may be more beneficial for many health and performance-based outcomes. Purpose: The purpose of this study was to compare the metabolic and ventilatory responses to a brief, intense interval protocol using a treadmill in the active and passive mode. Methods: Twelve physically fit participants (30.5±6.2y; 175.9±9.9 cm; 79.1±18.2 Kg) completed three exercise sessions. In the first session, biometric and demographic data were obtained prior to the performance of a peak VO …

Effect Of Dolphin Kick Timing On Breaststroke Pullout Performance, Taylor L. Adams, Mickey B. Scharbrough, Scott P. Mclean

International Journal of Exercise Science: Conference Proceedings

Breaststroke pullouts are now permitted to include a dolphin kick. Two variations of the pullout are distinguished by the timing of the dolphin kick within the movement. One variation uses an early-initiation of the dolphin kick (performed before the initiation of the arm pull) while a second variation uses a late-initiation of the dolphin kick (performed at the completion of the arm pull). PURPOSE: To compare the performance of two variations of breaststroke pullouts that incorporate a dolphin kick. METHODS: Fourteen collegiate swimmers (18.9 ± 1.17 years, 73.7 ± 8.54 kg, 174.5 ± 9.88 cm) who compete in breaststroke or …

Actual Versus Predicted Vo2max: A Comparison Of 4 Different Methods, David J. Buckley, James R. Rowe Jr

International Journal of Exercise Science: Conference Proceedings

ABSTRACT

Measuring expired gases (EGs) while performing a maximal (max) effort exercise test is considered the most accurate evaluation of VO₂ max. This methodology is not applicable for all populations.

PURPOSE: To compare VO₂max results from 1) University of Houston Non-Exercise Test (UHNET), 2) McArdle Step Test (MST), 3) Bruce Protocol measuring EGs to max (Bruce-EGs), and 4) Bruce Protocol using time to max (Bruce-TM). METHODS: Recreationally active men and women {n= 24 (16M/8W); age …

A Family History Of Type 2 Diabetes Does Not Impact Maximal Aerobic Capacity In Normoglycemic, Hispanic Males, Mario Garcia, Manuel Amador, Cesar Meza, Christopher Figueroa, Andrew Mcainch, Sudip Bajpeyi

International Journal of Exercise Science: Conference Proceedings

A family history of type 2 diabetes (FH+) is considered a risk factor for insulin resistance and poor cardiorespiratory fitness. However, it is not known if a FH+ impedes exercise-induced improvements in maximal aerobic capacity (VO₂max). Purpose: The purpose of this study was to determine if normoglycemic, sedentary, Hispanic men with FH+ have a lower VO₂max compared to those without a family history of type 2 diabetes (FH-) and if the improvement in VO₂max after 8-weeks of combined exercise training is comparable between FH- and FH+. Methods: 20 participants underwent 8 weeks of combined …

The Dose Effect Of Whey Protein On Insulin Responses In Pre-Diabetics And Type 2 Diabetics, Todd Castleberry Mr., Christopher Irvine 5098522, Michael Oldham, Matthew F. Brisebois, Sarah E. Deemer, Ryan Gordon, Aubrien Henderson, Vic Ben-Ezra

International Journal of Exercise Science: Conference Proceedings

People with pre-diabetes and type 2 diabetes have shown an increase in insulin secretion after ingesting 55 g of whey protein coupled with a glycemic challenge. However, the effect of lower amounts of whey protein on insulin responses remains unclear. Our hypothesis was that both 20 g and 30 g of whey consumption prior to an oral glucose tolerance test (OGTT) would produce an increase in insulin secretion, with 30 g producing the greatest increase compared to a control. PURPOSE: The purpose of this study was to examine the effect of two different doses of whey protein ingested 30 min …

Dose Effect Of Whey Protein On Gut Hormone Responses In Pre-Diabetics And Type 2 Diabetics, Christopher Irvine, Todd Castleberry, Michael Oldham, Matthew Brisebois, Sarah E. Deemer, Ryan Gordon, Aubrien Henderson, Vic Ben-Ezra

International Journal of Exercise Science: Conference Proceedings

GLP-1 and GIP have been shown to increase following a 50 g dose of whey protein prior to a high glycemic load in type 2 diabetics. However, this increase is reduced in diabetics compared to healthy individuals. Pancreatic polypeptide (PP) and peptide tyrosine tyrosine (PYY) also increase, while ghrelin decreases after the consumption of whey protein; however, it is not known if a similar hormone response occurs with a lower dose of whey protein prior to a glycemic load or if there is a dose effect. Our hypothesis was that 20 g and 30 g of whey protein would increase …

Validity Of Four-Compartment Models When Estimating Bone Mineral Content And Total Body Water With Single-Frequency Bioimpedance, Kassandra A. Jaramillo, Alexandra Loredo, Grant M. Tinsley, Brett S. Nickerson

International Journal of Exercise Science: Conference Proceedings

Bone mineral content (BMC) and total body water (TBW) are commonly assessed via dual energy X-ray absorptiometry (DXA) and bioimpedance spectroscopy (BIS), respectively, for a criterion 4-compartment body composition model (4C_CRITERION). However, single-frequency bioelectrical impedance analysis (SF-BIA) has been proposed as an alternative for calculating BMC and TBW. PURPOSE: The purpose of this study was to compare 4C models for body fat percent (BF%), fat-free mass (FFM), and fat mass (FM) when using SF-BIA individually for the estimation of BMC (4C_BMC) and TBW (4C_TBW) or in combination (4C_BMC+TBW). METHODS: Seventy-one men and …

3-Dimensional Biomechanical Comparison Of Spinal Posture In Yoga Practitioners And Non-Practitioners During A Seated And Standing Position, Savannah V. Wooten

International Journal of Exercise Science: Conference Proceedings

Yoga has been claimed to be beneficial for helping a series of clinical populations and improving ailments such as, but not limited to, stress, chronic back pain, muscle endurance, flexibility, balance, and posture. Whereas many of the above listed assertions have been scientifically investigated, there is a lack of objective evidence that supports the claim that yoga improves posture. PURPOSE: The purpose of this study is to compare a 3-D biomechanical analysis of spinal posture among yoga practitioners (YP) and Non yoga practitioners (NP) during seated and standing positions. METHODS: 10 yoga practitioners (M= 3, F=7) and 10 …

A Family History Of Type 2 Diabetes May Impair Glucose Area Under The Curve In Young, Healthy Hispanics, Cesar Meza, Manuel Amador, Mario Garcia, Christopher Figueroa, Andrew Mcainch, Sudip Bajpeyi

International Journal of Exercise Science: Conference Proceedings

Obesity and type 2 diabetes are associated with impaired glucose homeostasis and blood lipid profiles. Further, a family history of diabetes (FH) increases the risk for development of insulin resistance. However, it is unclear whether a FH impairs glucose tolerance, blood glucose and lipid profiles in young, healthy, normoglycemic adults. PURPOSE: To investigate whether a FH impairs glucose tolerance and blood lipid profile in healthy, sedentary Hispanic males. METHODS: 22 sedentary, normoglycemic, Mexican American males (mean±SEM: age:23±0.56 yrs; BMI: 26.9±0.98 kg/m²) with/without FH participated in the study. Glucose tolerance was assessed by calculating glucose area under …

Relative Energy Deficit (Female Triad), Prystyn M. Covington

International Journal of Exercise Science: Conference Proceedings

ABSTRACT CLINICAL PRESENTATION & EXAM: The relative energy deficit also known as RED-S or the Female Triad, is a common occurrence with females. RED-S occurs due to many factors such as increased energy output, decreased energy intake, or can sometimes be caused by both. RED-S in females is diagnosed by three symptoms: abnormal eating habits, osteoporosis, and functional hypothalamic amenorrhea. The patient does not need to experience all three symptoms to be diagnosed with RED-S. The energy deficit affects physiological functions such as cardiovascular health, immunity, protein synthesis, along with menstrual functions in females. ANATOMY & PATHOLOGY: Osteoporosis is a …
