A Family History Of Type 2 Diabetes Does Not Impact Skeletal Muscle Lipid Content, Jasmin Jenkins, Sudip Bajpeyi Feb 2019

A Family History Of Type 2 Diabetes Does Not Impact Skeletal Muscle Lipid Content, Jasmin Jenkins, Sudip Bajpeyi

International Journal of Exercise Science: Conference Proceedings

A high intramyocellular lipid (IMCL) has been associated not only with insulin resistance, obesity, and type 2 diabetes; but also in insulin sensitive endurance trained athletes – known as “athlete’s paradox”. A family history of type 2 diabetes (FH+) has been shown as a risk factor for the development of insulin resistance and type 2 diabetes (T2D). However, it is unclear whether a FH+ affects IMCL content and exercise induced changes in IMCL when compared to those without a family history of type 2 diabetes (FH-). PURPOSE: The purpose of this study were 1) to compare IMCL content between normoglycemic ...


Walking With Leg Blood Flow Restriction: Wide-Rigid Cuffs Vs. Narrow-Elastic Bands, Sten Stray-Gundersen, Savannah V. Wooten, Hirofumi Tanaka Feb 2019

Walking With Leg Blood Flow Restriction: Wide-Rigid Cuffs Vs. Narrow-Elastic Bands, Sten Stray-Gundersen, Savannah V. Wooten, Hirofumi Tanaka

International Journal of Exercise Science: Conference Proceedings

Blood flow restriction (BFR) training has become a popular form of exercise in recent years. The concept is that light-load exercise with BFR elicits similar adaptations achieved with heavy-load exercise. Walking exercise in combination with pressurized wide-rigid (WR) cuffs has been shown to elicit higher cardiac workload and a vascular dysfunction due presumably to reperfusion injury to the endothelium. In contrast, narrow-elastic (NE) BFR bands may elicit different hemodynamic effects, as the limb is able to increase in diameter with increased blood flow accompanying exercise. PURPOSE: To compare two distinct forms of BFR bands during light-intensity exercise on cardiovascular responses ...


Attenuated Pulsatile Load During Metaboreflex Activation Is Associated With Excess Adiposity In Dynapenic Postmenopausal Women, Arun Maharaj, Salvador Jaime, Stephen Fischer, Arturo Figueroa Feb 2019

Attenuated Pulsatile Load During Metaboreflex Activation Is Associated With Excess Adiposity In Dynapenic Postmenopausal Women, Arun Maharaj, Salvador Jaime, Stephen Fischer, Arturo Figueroa

International Journal of Exercise Science: Conference Proceedings

The age-related loss in muscle strength (dynapenia) is associated with elevated blood pressure (BP) and fat mass (FM). Aortic pulse pressure (PP), rather than brachial PP, more closely relates to cardiovascular events because it represents left ventricular pulsatile load, which is particularly important in older women. Purpose: To examine the impact of dynapenia and adiposity on aortic BP responses to metaboreflex activation (post-exercise muscle ischemia, PEMI) in postmenopausal women. Methods: 71 postmenopausal women [(dynapenic, n=41, 57±1 years), (non-dynapenic, n=30, 59±1 years)] were included in this study. FM, percent body fat (BF%) and percent lean mass (LM ...


Lower Leg Lean Mass Is Associated With Reduced Pulse Pressure Amplification In Postmenopausal Women, Stephen M. Fischer, Salvador J. Jaime, Arun Maharaj, Arturo Figueroa Feb 2019

Lower Leg Lean Mass Is Associated With Reduced Pulse Pressure Amplification In Postmenopausal Women, Stephen M. Fischer, Salvador J. Jaime, Arun Maharaj, Arturo Figueroa

International Journal of Exercise Science: Conference Proceedings

Sarcopenia, the age-related loss of skeletal muscle mass, has been associated with increased arterial stiffness (pulse wave velocity, PWV). Lower leg muscle mass has been associated with increased brachial-ankle PWV (baPWV), a measure of systemic arterial stiffness. Pulse pressure (PP) is lower in the aorta compared to the brachial artery (PP amplification, PPA), in healthy individuals. PPA decreases with aging due to increased aortic stiffening. Lower PPA is an independent predictor of cardiovascular death. It is unknown whether leg muscle mass is associated with lower PPA in postmenopausal women. Purpose: To examine relationships between leg lean mass (LegLM), PPA, and ...

Low Intensity Exercise Has Greater Acute Vascular Benefits For Reducing Arterial Stiffness In Hot Compared To Neutral Conditions, Kyleigh N. Allie, Julianna Kilpatrick, Paolo Salvador, Eric Rivas

International Journal of Exercise Science: Conference Proceedings

Both exercise and passive heating cause acute reductions in blood pressure. It is unknown if exercise-heat stress causes likewise reductions or greater when combined. PURPOSE: This project tested the hypothesis that the resting and exercise-heat stress cause hypotension and improvements in arterial stiffness. METHODS: Seven healthy active (7 day activity: 9887±3564 steps/day; VO2max: 52±10 mL/kg/min ) subjects (5M/2F, 24±9y, 171±6cm, 68±7kg) completed a 30 min baseline rest followed by 60 min at an exercise intensity of their choice that represented their perceived exertion (RPE) of 12 (between light and somewhat hard) on ...


The Effects Of A Single Bout Of Endurance Exercise On Glucose Transporter-4 (Glut-4) Content, Manuel Gomez, Sudip Bajpeyi Feb 2019

The Effects Of A Single Bout Of Endurance Exercise On Glucose Transporter-4 (Glut-4) Content, Manuel Gomez, Sudip Bajpeyi

International Journal of Exercise Science: Conference Proceedings

Glucose Transporter protein-4 (GLUT-4) is considered the predominant glucose transporter in skeletal muscle.

Intra-Day Variation In Lean Body Mass And Skeletal Muscle Mass Measures: A Pilot Study, Noe Deanda, Jordan B. Wainwright, Jeb F. Struder, Daniel Newmire

International Journal of Exercise Science: Conference Proceedings

Lean body mass (LBM) and its estimated measure of skeletal muscle mass (SKMM) is ~30 to ~40 % of total body weight. Measuring SKMM is an important assessment for both exercise and nutritional research. There is biological variation in dual X-ray absorptiometry (DXA) estimates related to subject presentation, changes in tissue hydration, as well as GI tract contents. PURPOSE: The purpose of this study is to examine how normal activities (e.g. eating, sleeping, exercise) influence LBM and SKMM measures using DXA in college students. METHODS: (Mean ± SEM; n = 42; Age: 26.9 ± 0.4 y; ht: 169.2 ± 1.3 ...


A Clinical Teaching Of Hamstring Strains, Josey Meyer, Chuck Ruot, Lindsay Edwards Feb 2019

A Clinical Teaching Of Hamstring Strains, Josey Meyer, Chuck Ruot, Lindsay Edwards

International Journal of Exercise Science: Conference Proceedings

CLINICAL PRESENTATION & EXAM: A patient with a hamstring strain will have pain and tenderness on his or her posterior thigh. The patient may also complain of difficulty extending the knee and sitting comfortably. Depending on the severity of the injury, there could be bruising and swelling in the thigh area causing a loss of hamstring strength. If one of the hamstring muscles is completely torn; the patient would feel a “popping” sensation upon injury. Thus, the patient would be unable to use the injured leg. A hamstring strain typically comes from muscle overload during an eccentric contraction. A muscle overload can occur when the hamstring muscles are stretched during a sprint or loaded while the muscles help the back leg push off from the ground. The specific type and severity of the injury can be diagnosed upon palpation of maximally painful and swollen areas. ANATOMY & PATHOLOGY: When a hamstring muscle is strained there is a partial or complete tear of the muscle. The ...


Exercise Leads To Increase In Smaller Lipid Droplet Morphology In Peripheral Region Of Muscle Fiber, Victoria Rosas Feb 2019

Exercise Leads To Increase In Smaller Lipid Droplet Morphology In Peripheral Region Of Muscle Fiber, Victoria Rosas

International Journal of Exercise Science: Conference Proceedings

In a previous study, we have shown that high fat overfeeding results in decreased smaller lipid droplet density in the peripheral region of skeletal muscle fiber. This decrease was associated with high fat overfeeding induced weight gain and insulin resistance. However, it is not clear whether an acute bout of exercise (elevated fat oxidation state) affects lipid droplet size. PURPOSE: To determine the effects of a single bout of endurance exercise on skeletal muscle lipid content and lipid droplet size. METHODS: Ten healthy male volunteers (Mean ± SEM; age: 23.11 ± 0.98; BMI: 23.27 ± 0.50 kg/m2 ...

The Impact Of Kinetic Energy Factors On Pitching Performance Of Ncaa Baseball Players, Blake George, Andrew A. Wolfe, Joe W. Priest, Randy Martin, Matt Laurent, Kayla Peak

International Journal of Exercise Science: Conference Proceedings

Kinetic energy is established by a mathematical equation involving the mass of an object and the speed at which the object travels, and is a relevant measure in regards to athletic performance due to frequent transfer of energy during sport (i.e. athlete to athlete (tackling), athlete to object (throwing), object to object (tennis/baseball hitting)). Previous research has utilized the 60-yd run-shuttle to examine kinetic energy factors (k-factor) of difference sports, recognizing significant differences in energy capability between gender, sport teams, and individual sport positions. The utilization of k-factor, pertaining to baseball, has distinguished significant positional (i.e. infielder ...

A Comparison Of High-Intensity Interval Exercise And Continuous Moderate-Intensity Exercise On Postprandial Metabolism: A Pilot Analysis., David J. Buckley, Broderick L. Dickerson, James R. Rowe Jr

International Journal of Exercise Science: Conference Proceedings

Both moderate-intensity continuous exercise (MICE) (performed for ≥ 1 hour) and high-intensity interval exercise (HIIE) (performed for ≤ 30 minutes) has been reported to reduce the magnitude of postprandial lipemia and glycemia. It is unclear if low-volume MICE and HIIE performed for a similar duration and expending similar amounts of energy would have a comparable or different effect on postprandial lipemia or glycemia. PURPOSE: Examine the effects of low-volume MICE and HIIE on postprandial glucose, insulin, and triglyceride (TG) concentration following a mixed meal (MM) ingested at 0.5 hours and 15.5 hours post-exercise. METHODS: Recreationally active men (n = 7; age ...


The Effect Of The Menstrual Cycle On Hemoglobin Mass, Melissa Keller, Sophie Lalande Feb 2019

The Effect Of The Menstrual Cycle On Hemoglobin Mass, Melissa Keller, Sophie Lalande

International Journal of Exercise Science: Conference Proceedings

The impact of the menstrual cycle on oxygen-carrying capacity remains equivocal. Previous studies reported either reductions or no significant changes in hemoglobin concentration during the follicular phase when compared to the luteal phase of the menstrual cycle. Changes in plasma volume associated with fluctuating estrogen and progesterone levels likely contribute to the variations in hemoglobin concentration observed throughout the menstrual cycle. Thus, measures of hemoglobin concentration do not accurately represent the oxygen-carrying capacity of the blood. Hemoglobin mass represents a more direct measure of oxygen-carrying capacity. However, the impact of menstrual blood loss on hemoglobin mass remains unknown. Purpose: To ...

Validity Of Body Volume Estimates From Infrared 3-Dimensional Scanning And Dual-Energy X-Ray Absorptiometry As Compared To Air Displacement Plethysmography, Marqui Benavides, Michael Moore, Jacob Dellinger, Claire Underwood, Tyler Dierolf, Brian Adamson, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

Traditional methods of estimating body volume (BV) such as hydrostatic weighing and air-displacement plethysmography (ADP) could theoretically be replaced using BV estimates obtained by dual-energy x-ray absorptiometry (DXA) or infrared 3-dimensional (3D) scanning devices. Multiple 3D scanning technologies have recently become popularized, including scanners that acquire data through pattern deformations caused by the projected light over the 3D object (i.e., structured light [SL] scanners) or by calculating depth from the time it takes reflected photons to reach the scanner’s image sensor (i.e. time of flight [ToF] scanners). While these 3D scanning technologies currently predict body composition based ...

A Wearable Garment To Mitigate Low Back Pain In Astronauts, Curtis Neeld, Miranda Moore, Alexis Quintana, Audra Romans, Arianne Scheller, Charles Swieczkowski, Nicholas A. Levine, Brandon R. Rigby

International Journal of Exercise Science: Conference Proceedings

The microgravity environment of space is known to cause a wide array of adverse physiological effects on the bodies of astronauts. Among these effects, low back pain due to space adaptation is commonly reported by astronauts. In fact, this pain, caused primarily by atrophy of the erector spinae musculature, has the highest incidence rate among all musculoskeletal-related conditions reported by this population while in space. Low back pain and the consequences of other medical conditions may become magnified as the duration of missions increases over the next few decades. Therefore, determining methods of preventing and mitigating the deleterious effects of ...


Hemodynamic And Pressor Responses To Combination Of Yoga And Blood Flow Restriction, Savannah V. Wooten, Sten Stray-Gundersen, Hirofumi Tanaka Feb 2019

Hemodynamic And Pressor Responses To Combination Of Yoga And Blood Flow Restriction, Savannah V. Wooten, Sten Stray-Gundersen, Hirofumi Tanaka

International Journal of Exercise Science: Conference Proceedings

Blood flow restriction (BFR) training has been increasingly incorporated into a more common activity of daily exercise (e.g., yoga). However, BFR may increase blood pressure and myocardial oxygen demand by augmenting vascular resistance. Yoga is characterized by systemic isometric exercises and accompanied by marked pressor responses. This raises the concern of exaggerated cardiovascular responses when yoga is performed with BFR. Purpose: To determine the impact of a combination of yoga and BFR on cardiovascular responses. Methods: Twenty young healthy participants (M =10, F=10) performed 20 yoga poses with and without BFR bands placed on both legs. Beat by ...

Bilateral Lean Mass And Dynamic Balance Asymmetry In Collegiate Athletes, Guadalupe Gabriela Herrera, Vipa Bernhardt Feb 2019

Bilateral Lean Mass And Dynamic Balance Asymmetry In Collegiate Athletes, Guadalupe Gabriela Herrera, Vipa Bernhardt

International Journal of Exercise Science: Conference Proceedings

Laterality, or lateral dominance may lead to asymmetry in muscle mass and strength, which in turn could lead to differences in stability and balance. Muscular asymmetry and dynamic balance asymmetry have been independently linked with increased injury risk. For example, athletes with >4cm anterior reach distance differences (ΔARD) were found to be at significantly higher risk to incur injuries. PURPOSE: However, it is unknown if there is an association between muscle mass asymmetry and dynamic balance. Nor is it known if these factors change throughout the sports’ seasonal periods (i.e., off-, pre-, and post-season). The purpose of this preliminary ...

Repetitive exercise on consecutive days is a key component of many long-term training plans. This type of exercise results in muscle inflammation and soreness that limits the capacity to sustain exercise at a high effort. Several dietary polyphenols have the capacity to manage inflammation and thus supplementation may be an effective component of a long-term training plan. PURPOSE:The purpose of this study was to investigate the effect of combined oral supplementation with curcumin and boswellia serrata prior to and following three consecutive days of intense interval exercise. METHODS:All protocols were approved by the University IRB committee and participants ...


Gender Differences In Body Esteem Following Social Media Exposure, Isabel Soto, Jessica Gonzalez, Zavina Gonzalez, Chelsea K. Duncan, Brian E. Menaker, Amber M. Shipherd Feb 2019

Gender Differences In Body Esteem Following Social Media Exposure, Isabel Soto, Jessica Gonzalez, Zavina Gonzalez, Chelsea K. Duncan, Brian E. Menaker, Amber M. Shipherd

International Journal of Exercise Science: Conference Proceedings

Prior research has uncovered upwards of 90% of college students feel dissatisfied with their body image or appearance. Social media is one of the biggest influences of negative body image by pressuring individuals to adhere to often unrealistic appearance ideals. Women often have a more negative view towards their body, but the rate of males with body image disturbances has increased substantially. In addition to gender differences, ethnic differences have also been found in body image or body esteem, however, the majority of research has focused on Caucasians. This has created a need to examine body esteem in other ethnicities ...


Running Economy Strongly Related To Ground Contact Time Imbalances, Aaron D. Piper, Erica G. Knowles, Nicholas A. Guerra, Eric J. Jones, Dustin P. Joubert Feb 2019

Running Economy Strongly Related To Ground Contact Time Imbalances, Aaron D. Piper, Erica G. Knowles, Nicholas A. Guerra, Eric J. Jones, Dustin P. Joubert

International Journal of Exercise Science: Conference Proceedings

Running economy (RE) can be defined as the oxygen consumption or caloric unit cost required to move at a specific velocity. In addition to a runner’s maximal oxygen uptake (VO2max) and lactate threshold (LT), RE is a key endurance performance determinant. Better RE is advantageous as it represents the ability to run at a lower relative percentage of VO2max at a given speed and reduces the rate of energy depletion. Ground contact time (GCT) has been associated with RE, however it has not been established how GCT imbalances between feet impact economy. Purpose: Determine the relationship between cadence, GCT ...
