Partitioning The Role Of Myocardial Steatosis On Left Ventricular Function, Andrew Oneglia

Kinesiology Dissertations - Archive

Preclinical studies have long suggested that excess lipid accumulation within cardiomyocytes (myocardial steatosis) leads to adverse cardiac remodeling and ventricular systolic and diastolic dysfunction. Whether myocardial steatosis negatively affects the human heart is less clear. Innovations in 1H magnetic resonance spectroscopy (MRS), introduced nearly 20 years ago, provide a method for in vivo quantification of myocardial triglyceride content that has been used to describe myocardial steatosis in obesity, type-2 diabetes, and across multiple disease states. However, most of this literature consists of cross-sectional observations. While these studies identify associations between myocardial steatosis and adverse remodeling and/or cardiac function, the presence …

Age-Related Differences In Kinematics, Kinetics, And Muscle Synergy Patterns Following A Sudden Gait Perturbation: Changes In Movement Strategies And Implications For Fall Prevention Rehabilitation, Woohyoung Jeon, Ahmed Ramadan, Jill Whitall, Nesreen Alissa, Kelly Westlake

Health & Kinesiology Faculty Publications and Presentations

Falls in older adults are leading causes of fatal and non-fatal injuries, negatively impacting quality of life among those in this demographic. Most elderly falls occur due to unrecoverable limb collapse during balance control in the single-limb support (SLS) phase. To understand why older adults are more susceptible to falls than younger adults, we investigated age-related differences in lower limb kinematics, kinetics, and muscle synergy patterns during SLS, as well as their relationship to postural control strategies. Thirteen older and thirteen younger healthy adults were compared during the SLS phase of balance recovery following an unexpected surface drop perturbation. Compared …

Age-Related Differences In Motor Performance, Jessica Anne Prebor

Rehabilitation Sciences Theses & Dissertations

The purpose of this work was to study the age effects on average performance and variability of movement responses in children, young adults, and older adults across multiple motor tasks. Optimal motor performance is observed in healthy young adults with declines observed at either end of the lifespan. This pattern has been represented as a U-shaped/inverted U-shaped curve. Little is known about if this pattern persists in chewing dynamics. While chewing has been found to improve aspects of attention, a cognitive function, research is limited on the relationship between chewing and other motor tasks.

The Influence Of Concussion History And Head Acceleration On Lower Extremity Function, Warren Forbes

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sport-related concussions (SRCs) play a very debilitative role in athletics with between 1.7 – 3 million SRCs occurring annually (Clay et al., 2013; Zuckerman et al., 2015). This equates to upwards of 21.5 SRCs per 1000 athletic exposures. Research pertaining to SRC has received intense focus because of the substantial financial impact on the US healthcare system as well as the negative impact that SRCs have on the quality of life of athletes. Much of the research concerning SRC has been centered around management and ensuring adequate recovery from SRC-related symptoms. The current return to play (RTP) criteria from an …

Depression, Anxiety, And Estimated Cardiorespiratory Fitness In College Students, Christian Ison

UNLV Theses, Dissertations, Professional Papers, and Capstones

Depression and anxiety disorders are two common mental health conditions worldwide. College students are considered a high-risk population for the development of these conditions. Improved cardiorespiratory fitness (CRF) has been shown to decrease depression and anxiety risk, symptoms, and severity but this relationship and the extent to which improved CRF can reduce these risks has yet to be examined in the college student population. Validated and reliable non-exercise estimated cardiorespiratory fitness (eCRF) algorithms could be used to identify relationships and associations with depression and anxiety severity levels among college students. The purpose of this study was to assess eCRF and …

The Effects Of Low Volume High-Intensity Interval Training Vs. Moderate-Intensity Interval Training With Blood Flow Restriction On Body Composition, Hormone Concentration, And Arterial Elasticity In Overweight And Obese Male Adults, Alexis Lopez

Theses and Dissertations

PURPOSE: This study compared the effects of HIIT and MIIT+BFR on the adaptations in body composition, salivary hormone concentration, peak oxygen uptake, anaerobic parameters, and arterial elasticity in young overweight and obese male adults.

RESULTS: There was a significant increase in total BMC (p<0.01), leg BMC (p<0.05), and trunk BMC (p<0.05) from baseline in response to HIIT. MIIT+BFR significantly increased LFM/TFM Ratio from baseline (p<0.01). HIIT significantly decreased AIx@75 (p<0.05) and CI (p<0.05). There was a significant increase in ISO 180o Away (p<0.05), Thor Begin. (p<0.01), and Thor Mid. (p<0.05) in response to HIIT. MIIT+BFR had a superior increase in Thor Mid. (p<0.05) and significantly increased ISO 180o Toward (p<0.01), VO2peak (p<0.05), and VO2peak:Time (p<0.05). In the last training session, HIIT significantly increased salivary leptin (p<0.05), but MIIT+BFR had a superior increase in salivary leptin (p<0.01) from pre- to post exercise.

CONCLUSION: HIIT significantly improved total BMC, leg BMC, trunk BMC, and AIx@75 but decreased CI from baseline. HIIT increased quad muscle strength, whereas MIIT+BFR increased hamstring muscle strength. HIIT and MIIT+BFR significantly increased peak torque in Thor Mid and salivary leptin. Only MIIT+BFR significantly improved VO2peak.

Effects Of Chewing Time On Gastrointestinal Discomfort, Substrate Use, And Performance During Running, Thomas Geaney

Human Movement Studies & Special Education Theses & Dissertations

Previous research has shown that food particle size affects gastric processing. For example, food particles greater than 3 mm may delay gastric emptying under certain conditions. Delays in gastric emptying can be problematic during aerobic exercise, leading to nausea, bloating, fullness, and other gastrointestinal (GI) symptoms. In some cases, symptoms can be severe enough to negatively affect athletic performance. This study investigated the effects of manipulating chewing duration of carbohydrate sports bars on GI discomfort, physiological responses, and performance during endurance running. This crossover study recruited 12 male runners (age: 36.4 ± 7.2 years, VO_2peak: 57.2 ± 4.7 …

Effects Of Circadian Rhythm Disruption And Social Jetlag On The Cardiometabolic Adaptations To Exercise, Michael Bevan Dial

UNLV Theses, Dissertations, Professional Papers, and Capstones

Circadian rhythms lie within every tissue and cell and regulate cellular and tissue processes and functions based upon the time of day. Disrupting the circadian clock results in impaired tissue and organ activity and higher risk of cardiometabolic diseases. A common form of circadian rhythm disruption is social jetlag (SJL), which represents the misalignment of sleep and wake times on free days and work days (i.e. weekend). The time of day of exercise affects the adaptations that are derived from exercise. Within the heart muscle, disparate levels of exercise-induced hypertrophy, circadian clock gene expression, and mitochondrial content were all dependent …

Effects Of Physical Characteristics Of Placebos On Exercise Performance, Owen Sipes

Human Movement Studies & Special Education Theses & Dissertations

Previous research has shown that placebos can impact medical conditions such as irritable bowel syndrome and depression as well as elicit analgesic effects and improvements in certain exercise performances. These placebo responses occur from a variety of alterations to the placebo itself or through verbal suggestion of how helpful the placebo will be. This study aimed to observe whether changing the color and quantity of capsules can induce improvements in both vertical jump and hand grip strength. This deceptive, parallel study consisted of 28 participants, with a mean age of 24.9 (±4.3) years old, that were randomly assigned to receive …
