The Training Of A Para Powerlifter: A Case Study Of Adaptive Monitoring, Training And Overcoming, Derek Wilcox Dec 2019

The Training Of A Para Powerlifter: A Case Study Of Adaptive Monitoring, Training And Overcoming, Derek Wilcox

Electronic Theses and Dissertations

Paralympic athletes (PA) appear to be more prone to chronic overuse injuries from daily wheelchair or crutch use. Over half of these injuries are shoulder related which can deleteriously impact quality of life. Adaptive powerlifters (AP) are a subdivision of Paralympic athletes and are at a higher risk for catastrophic injuries as compared to their counterparts, due to the compound of fatigue and lifting of maximal weights. For this reason, it is vital to have well-designed training plans for these athletes in order to preserve quality of life and maximize performance in competition. Unfortunately, there is a lack of literature ...


Tracing Nutrient Sources To Lipid Production In Birds And Insects Using Stable Isotope (Δ13c, Δ2h) Tracers: Implications For Nutritional Physiology Of Migratory Species, Libesha Anparasan Oct 2019

Tracing Nutrient Sources To Lipid Production In Birds And Insects Using Stable Isotope (Δ13c, Δ2h) Tracers: Implications For Nutritional Physiology Of Migratory Species, Libesha Anparasan

Electronic Thesis and Dissertation Repository

Using stable isotope measurements of inert tissues to determine origins and migratory patterns is well established. However, isotopically determining nutritional origins of lipids, the primary fuel of migration, has not been attempted. I explored isotopic links between diet and stored lipids in captive White-throated Sparrows (Zonotrichia albicollis) and true armyworm moths (Mythimna unipuncta) using δ13C and δ2H measurements. Isotopic discrimination between body lipids and diet was established as linear calibration functions. Isotopic uptake following a diet switch in moths was used to trace lipid accumulation over time. Isotopic correlations between breath metabolic by-products of fed and ...


Excess No Stabilizes The Luminal Domain Of Stim2 In A Cys-Specific Manner Thereby Regulating Basal Calcium Homeostasis And Store-Operated Calcium Entry, Matthew Novello Sep 2019

Excess No Stabilizes The Luminal Domain Of Stim2 In A Cys-Specific Manner Thereby Regulating Basal Calcium Homeostasis And Store-Operated Calcium Entry, Matthew Novello

Electronic Thesis and Dissertation Repository

Stromal-interaction molecule 2 (STIM2) is an endoplasmic reticulum (ER) membrane-inserted Ca2+-sensing protein which, together with the plasma membrane Ca2+ channel Orai1, regulates basal Ca2+ homeostasis and store-operated Ca2+ entry (SOCE). Recent evidence suggests that S-nitrosylation, which is the covalent attachment of a nitric oxide (NO) moiety to a cysteine thiol, can attenuate the function of the paralog STIM1 protein. Compared to STIM1, STIM2 also functions as a basal Ca2+ homeostatic feedback regulator. Therefore, the objective of my study was to evaluate the susceptibility of STIM2 to S-nitrosylation and the effects that this ...


Assessing The Structure-Function Relationships Of The Apolipoprotein(A) Kringle Iv Sub-Type 10 Domain, Matthew J. Borrelli Aug 2019

Assessing The Structure-Function Relationships Of The Apolipoprotein(A) Kringle Iv Sub-Type 10 Domain, Matthew J. Borrelli

Electronic Thesis and Dissertation Repository

Elevated plasma lipoprotein(a) (Lp(a)) is the most prevalent heritable risk factor in the development of cardiovascular disease. The apolipoprotein(a) (apo(a)) component of Lp(a) is strongly implicated in the pathogenicity of Lp(a). It is hypothesized that the inflammatory potential of Lp(a)/apo(a) is mediated by the lysine binding ability of the apo(a) kringle IV10 (KIV10) domain, along with its covalently bound oxidized phospholipid (oxPL). Using targeted mutagenesis, two novel null alleles for the LPA gene that generate non-secretable apo(a) species have been identified, resulting from amino acid substitutions in the KIV10 ...


Mapping And Functional Characterization Of Proteolytic Cleavage Of Murine Kidney Injury Molecule-1, Saranga Sriranganathan Aug 2019

Mapping And Functional Characterization Of Proteolytic Cleavage Of Murine Kidney Injury Molecule-1, Saranga Sriranganathan

Electronic Thesis and Dissertation Repository

Kidney injury molecule-1 (KIM-1) is a transmembrane glycoprotein expressed apically on proximal tubule epithelia during acute kidney injury (AKI). KIM-1, as a phagocytic receptor, facilitates clearance of apoptotic cells (efferocytosis) from tubular lumen, thereby reducing inflammation and promoting repair. Human KIM-1 undergoes spontaneous and accelerated ectodomain shedding into urine and blood via metalloproteases; tumour necrosis factor-a converting enzyme (TACE/ADAM17) and a disintegrin and metalloprotease 10 (ADAM10). Blood and urine KIM-1 are clinical AKI biomarkers, however, biological significance of KIM-1 shedding is unknown. To study this in vivo in mice, I first aimed to identify murine KIM-1 cleavage site and ...


Osmoregulation And Salinity Preference In Juvenile Sandbar Sharks (Carcharhinus Plumbeus) In Winyah Bay, Sc, Usa, Jessica Wingar Aug 2019

Osmoregulation And Salinity Preference In Juvenile Sandbar Sharks (Carcharhinus Plumbeus) In Winyah Bay, Sc, Usa, Jessica Wingar

Electronic Theses and Dissertations

Juvenile sandbar sharks (Carcharhinus plumbeus) have been caught in salinities ranging from 7 – 40. In Winyah Bay, a partially mixed estuary in Northeast SC, juvenile sandbar sharks tidally alternate between higher tides in middle bay and lower tides in lower bay. To assess salinity preference and duration in eight acoustically-tagged juvenile sandbar sharks in different salinities, acoustic receivers with salinity loggers were placed throughout Winyah Bay. Juvenile sandbar sharks were caught in salinities from 17.2 to 36.1 and acoustic detections were recorded from 11.5 to 24.7 by salinity loggers in middle bay. Smaller juvenile sandbar sharks ...


Response Of Early Life Stage Homarus Americanus To Ocean Warming And Acidification: An Interpopulation Comparison, Maura K. Niemisto Aug 2019

Response Of Early Life Stage Homarus Americanus To Ocean Warming And Acidification: An Interpopulation Comparison, Maura K. Niemisto

Electronic Theses and Dissertations

Anthropogenic carbon released into the atmosphere is driving rapid, concurrent increases in temperature and acidity across the world’s oceans, most prominently in northern latitudes. The geographic range of the iconic American lobster (Homarus americanus) spans a steep thermal gradient and one of the most rapidly warming oceanic environments. Understanding the interactive effects of ocean warming and acidification on this species’ most vulnerable early life stages is important to predict its response to climate change on a stage-specific and population level. This study compares the responses of lobster larvae from two sub-populations spanning New England’s north-south temperature gradient (southern ...

The Effects Of Branched Chained Amino Acid Supplementation On Acute Markers Of Fatigue And Performance, Joseph Walters Aug 2019

The Effects Of Branched Chained Amino Acid Supplementation On Acute Markers Of Fatigue And Performance, Joseph Walters

Electronic Theses and Dissertations

The purposes of this dissertation were to investigate the acute effects of branched-chain amino acids on psychological, physiological, and subsequent performance changes following high volume resistance training. The rationale for this study design was based on abrupt or contiguous training/ competitions that specific athletes encounter in a competitive season. This study design also sought to fill some gaps in the scientific literature concerning the efficacy of BCAAs for subjective fatigue in a resistance training paradigm. To address the purposes of this dissertation, a one-week study was conducted on resistance trained males, in which half of the subjects were randomly selected ...


White-Nose Syndrome And Immune Responses In A Resistant Bat Species (Eptesicus Fuscus), Keslie Skye Naffa Aug 2019

White-Nose Syndrome And Immune Responses In A Resistant Bat Species (Eptesicus Fuscus), Keslie Skye Naffa

MSU Graduate Theses

White-nose syndrome (WNS) has had a large negative impact on bat populations across eastern North America since its arrival in 2006. Bats affected by WNS appear to die of starvation, possibly due to the increased arousals during hibernation when there is no food present to replace the energy used to arouse. During hibernation, the bat’s immune system should be suppressed. However, once a bat of a susceptible species is exposed to the fungus that causes WNS, Psuedogymnoascus destructans (Pd), the immune system seems to respond, potentially causing an elevation in metabolic rate, which may cause the bat to arouse ...


Influence Of Heating And Biological Sex On Vascular Dysfunction Associated With Long-Duration Sitting And Standing, Aaron Richard Caldwell Aug 2019

Influence Of Heating And Biological Sex On Vascular Dysfunction Associated With Long-Duration Sitting And Standing, Aaron Richard Caldwell

Theses and Dissertations

Purpose: The purpose of these studies was to determine if arterial angulations (through sitting or standing), shear stress (through local heating), or a combination of these factors affected vascular function. Moreover, this studied estimated the magnitude of the effect that biological sex has on these vascular responses. Methods: Twenty-six healthy, young (18-40 years old) males (n=13) and females (n=13) completed two experimental trials (2-h sitting and 2-h standing). In a randomized fashion, one leg was passively heated in order to increase shear rate. Following a 48-h washout, participants returned to the laboratory to complete the other trial. Flow-mediated ...


Effects Of High-Carbohydrate Versus Mixed-Macronutrient Meals On Soccer Physiology And Performance, Jaison Lee Wynne Jul 2019

Effects Of High-Carbohydrate Versus Mixed-Macronutrient Meals On Soccer Physiology And Performance, Jaison Lee Wynne

Human Movement Sciences Theses & Dissertations

The purpose of the study was to measure the effects of an acute pre-competition high-carbohydrate (HCHO) meal versus a mixed-macronutrient (MM) meal on physiology, perceptual responses, and performance in 15 division I female collegiate soccer players. Being there are conjectural advantages to pre-exercise meals higher in fiber, fat, and protein, this study was conducted to evaluate the physiological and perceptual effects of pre-competition MM meals. This study used a randomized, investigator-blinded, crossover design involving two dietary interventions – HCHO and MM meals – that were consumed four hours prior to two separate intra-squad soccer scrimmages. Assessments included running metrics via global positioning ...


The Role Of C-Kit And Insulin Receptor Tyrosine Kinases In Beta Cell Function And Insulin Secretion, Amanda Oakie Jun 2019

The Role Of C-Kit And Insulin Receptor Tyrosine Kinases In Beta Cell Function And Insulin Secretion, Amanda Oakie

Electronic Thesis and Dissertation Repository

The receptor tyrosine kinases (RTKs) c-Kit and insulin receptor (IR) initiate similar intracellular signalling pathways in pancreatic beta cells to regulate beta cell proliferation, survival, and insulin secretion. Mice with a c-Kit overexpression specifically in beta cells (c-KitβTg) demonstrated improved beta cell proliferation and insulin secretion compared to control mice, and islets from c-KitβTg mice also demonstrated increased IR expression. The potential interplay between c-Kit and IR and their roles during ageing and metabolic stress are not currently known. This work reports the examination of c-Kit and IR signalling using in vitro and in vivo models to determine their effects ...


Oleic Acid Attenuates Palmitic Acid-Induced Impairments In Mouse Blastocyst Development, Maisoon Dafalla Yousif Jun 2019

Oleic Acid Attenuates Palmitic Acid-Induced Impairments In Mouse Blastocyst Development, Maisoon Dafalla Yousif

Electronic Thesis and Dissertation Repository

Palmitic acid (PA) and oleic acid (OA) are the most abundant saturated and monounsaturated non-esterified fatty acids, respectively, in serum. The consequences of PA and OA treatment on preimplantation mouse embryo development were investigated. It was hypothesized that OA treatment from the two-cell stage onwards would attenuate PA-induced reductions in mouse blastocyst development. PA significantly reduced development to the blastocyst stage. Transcript analysis revealed that PA increased ER stress pathway markers activating transcription factor 3 and C/EBP homologous protein transcripts, and XBP1 splicing. Co-culture of PA-treated embryos with OA prevented this PA-induced ER stress and rescued blastocyst development. Cytoplasmic ...


Effects Of Life-Long Wheel Running Behavior On Plantar Flexor Contractile Properties, Alexander Nicholas Beechko Jun 2019

Effects Of Life-Long Wheel Running Behavior On Plantar Flexor Contractile Properties, Alexander Nicholas Beechko

Electronic Theses, Projects, and Dissertations

Aging in skeletal muscle is characterized by a loss in muscular performance. This is in part related to the direct loss of muscle mass due to senescence, known as sarcopenia. With age, skeletal muscles lose force production, contractile speed, and power production. The force velocity relationship of muscle is a product of force production and contraction speed, both of which decline with age; however, the mechanisms and trajectory of this decline are not well understood. Exercise has positive effects on muscle, and thus may assist in maintaining performance in old age. However, few long-term studies have been performed to examine ...


Mechanics Of Phenotypic Aging Trajectories In C. Elegans And Humans, William Zhang May 2019

Mechanics Of Phenotypic Aging Trajectories In C. Elegans And Humans, William Zhang

Arts & Sciences Electronic Theses and Dissertations

Overall, my dissertation integrates longitudinal measurements of physiology to investigate the aging process. In the first half, I examine the surprising and largely unexplained degree of variation in lifespan within even homogeneous populations. I sought to understand how physiological aging differs between long- and short-lived individuals within a population of genetically identical C. elegans reared in a homogeneous environment. Using a novel culture apparatus, I longitudinally monitored aspects of aging physiology across a large population of isolated individuals. Aggregating several measures into an overall estimate of senescence, I find that long- and short-lived individuals start adulthood on an equal physiological ...


Role Of Pkcbeta And Oxidant Signaling In Neonatal Pulmonary Hypertension, Joshua R. Sheak May 2019

Role Of Pkcbeta And Oxidant Signaling In Neonatal Pulmonary Hypertension, Joshua R. Sheak

Biomedical Sciences ETDs

Chronic hypoxia (CH)-induced vasoconstriction has been implicated in the pathogenesis of pulmonary hypertension (pHTN) in infants with chronic cardiorespiratory disorders. Although endothelial dysfunction, reduced nitric oxide (NO) bioavailability and oxidative stress contribute to a variety of cardiovascular disorders, their contribution to enhanced vasoconstrictor reactivity in neonatal pHTN is poorly understood. We therefore hypothesized that neonatal CH augments pulmonary vasoconstrictor reactivity by limiting NO-dependent pulmonary vasodilation and by promoting the generation of reactive oxygen species (ROS).

Enzymatic sources of ROS in the vasculature include NADPH oxidase isoforms, xanthine oxidase, and uncoupled endothelial nitric oxide synthase (eNOS). The mitochondria are also ...


Living On The Edge: Thermophysiology Of The Southern Flying Squirrel At Its Northern Range Margin, Vanessa R. Hensley May 2019

Living On The Edge: Thermophysiology Of The Southern Flying Squirrel At Its Northern Range Margin, Vanessa R. Hensley

Electronic Theses and Dissertations

Climate change has the potential to upset entire ecological systems, making predictive models of the utmost importance. The incorporation of physiological parameters into predictive models not only bolsters their accuracy but also provides a mechanistic explanation for ecological changes already observed and those yet to come. North American flying squirrels, for example, have already experienced dramatic range shifts northward over recent decades, with climate change being the suspected driver. While other studies have focused on warming winter temperatures, I explored the hypothesis that rising summer temperatures were driving the observed range shifts. Unable to find a reliable population of the ...


Effects Of Rest Position On Ultrasound-Derived Morphological Characteristics Of The Vastus Lateralis And Lower-Body Force Production, Alyssa Varanoske May 2019

Effects Of Rest Position On Ultrasound-Derived Morphological Characteristics Of The Vastus Lateralis And Lower-Body Force Production, Alyssa Varanoske

Electronic Theses and Dissertations

INTRODUCTION: Ultrasound assessment of the lower body typically encompasses 10-15 minutes of supine rest prior to examination because of the potential influence of gravitational fluid shifts on tissue size and composition. However, examination of the vastus lateralis (VL) muscle requires individuals to lay in the lateral recumbent position, and this change in position may influence muscle morphological characteristics and their ability to predict muscle function. PURPOSE: The purpose of this investigation was to examine the effect of rest position on ultrasound-derived morphological characteristics of the VL and to determine whether or not rest position affects the relationships between muscle morphological ...


A Mixed-Methods Approach To Understanding The Relationship Between Mental Toughness And The Effect Of Music On Exercise Performance, Kayla Baker May 2019

A Mixed-Methods Approach To Understanding The Relationship Between Mental Toughness And The Effect Of Music On Exercise Performance, Kayla Baker

Electronic Theses and Dissertations

Previous research has investigated the use of music as an ergogenic aid for exercise performance; however, the effect of music on exercise may differ between individuals of varying levels of mental toughness (MT). Purpose: The purpose of this study is to examine the moderating effect of MT on the effect of listening to music during exercise. Methods: The current study used a counter-balanced design, utilizing a mixed-methods approach. Thirty-one recreationally-active individuals (22.13 ± 2.11 yrs, 1.73 ± .10 m, 75.68 ± 14.67 kg, 42.89 ± 5.31 mL·kg·min-1; 65.5% males) were recruited for this study ...


Comparative Plasma Proteomics In Muscle Atrophy Induced By Cancer Cachexia And Hindlimb Unloading, Kirsten Rene Dunlap May 2019

Comparative Plasma Proteomics In Muscle Atrophy Induced By Cancer Cachexia And Hindlimb Unloading, Kirsten Rene Dunlap

Theses and Dissertations

Introduction: Muscle atrophy results from a dysfunction in protein turnover that leads to loss of mass and function and occurs concurrently with multiple pathologies such as cancer and extended bed rest. Atrophy reduces overall quality of life while increasing morbidity and mortality. Currently, efficacious therapeutic interventions to treat and prevent muscle wasting in all its forms are lacking, however if conserved mechanisms can be identified between wasting conditions, this would aid in the development of multipurpose therapeutics to ameliorate this pathology. Purpose: To examine circulating factors present across atrophic pathologies. Methods: 35 male C57BL/6J mice were assigned to hindlimb ...


Apnea Training And Physical Characteristics: Enhancement Of The Dive Response, Apneic Time, And Recovery, Nathanael Stanford May 2019

Apnea Training And Physical Characteristics: Enhancement Of The Dive Response, Apneic Time, And Recovery, Nathanael Stanford

Boise State University Theses and Dissertations

Human breath-hold diving (free diving) has been gaining popularity as new individuals participate in the sport every year. Carbon dioxide (CO2) breath-hold tables have been widely implemented as a training modality and prescribe constant submaximal apneic durations with gradually decreasing recovery times to increase hypercapnic resiliency. Previous studies implementing maximal duration apnea training have found enhancements in apneic duration and the mammalian dive reflex (MDR), which is elicited by apnea and augmented with facial immersion. The MDR results in bradycardia and peripheral vasoconstriction to redistribute blood to vital organs and elicit oxygen (O2) conserving resulting in prolonged apneas ...


Noninvasive Myographical Assessments Following Unaccustomed Resistance Exercise, Carleigh Boone May 2019

Noninvasive Myographical Assessments Following Unaccustomed Resistance Exercise, Carleigh Boone

Electronic Theses and Dissertations

Traditionally, post-exercise muscular alterations have been examined using invasive techniques that lack the ability to single out individual muscle groups. Sonomyography, tensiomyography, and electrical impedance myography allow for noninvasive skeletal muscle assessment. This project aimed to examine changes in muscle contractility and composition that occur in the early stages of recovery following unaccustomed exercise. METHODS: Twenty-one untrained adults (21.9 ± 1.9 y) performed exercise – 10 × 10 maximal eccentric knee extensions – with their nondominant leg. For each repetition, participants moved through 90° range of motion at 90°•s-1 with a passive return to the start position. Each set was separated ...


Growth Characteristics And Lipid Metabolism Of Cultured Migratory Bird Skeletal Muscle Cells, Kevin G. Young Apr 2019

Growth Characteristics And Lipid Metabolism Of Cultured Migratory Bird Skeletal Muscle Cells, Kevin G. Young

Electronic Thesis and Dissertation Repository

Diets rich in n-3 polyunsaturated fatty acids (PUFA) may alter the muscle metabolism of migratory birds, improving their endurance performance. I established and validated for the first time in vitro muscle models of a migratory songbird (yellow-rumped warbler, Setophaga coronata coronata) and shorebird (sanderling, Calidris alba). To evaluate the role of n-3 PUFA in improving fatty acid metabolism in migratory bird muscle, I measured metabolic outcomes following n-3 PUFA supplementation in these two avian cell types and a murine (Mus musculus, C2C12) cell line. PUFA supplementation in C2C12 cells increased metabolic transcription factor expression ...


Thermal Biology Of Temperate And High-Latitude Arachnids, Susan E. Anthony Apr 2019

Thermal Biology Of Temperate And High-Latitude Arachnids, Susan E. Anthony

Electronic Thesis and Dissertation Repository

Temperate and high latitude terrestrial ecosystems have high thermal variability, and the ectotherms that inhabit these regions must have thermal tolerances that mirror these temperatures. However, the thermal limits of many high-latitude arachnids are unknown, as well as any underlying mechanisms of seasonal plasticity for any arachnid. The objective of my thesis is to measure the thermal tolerances of temperate, Arctic, and sub-Arctic arachnids, and identify if they have thermal plasticity, either seasonally or following acclimation. I collected the high-latitude pseudoscorpion Wyochernes asiaticus streamside from the Yukon Territory, where besides large thermal variability, they are also inundated with spring flooding ...


Dental Topographic Analysis Of Maxillary And Mandibular Phyllostomid Bat Dentitions: Implications For Dietary Prediction In The Fossil Record, Colin Pellegrom Apr 2019

Dental Topographic Analysis Of Maxillary And Mandibular Phyllostomid Bat Dentitions: Implications For Dietary Prediction In The Fossil Record, Colin Pellegrom

Masters Theses

Mammalian dental anatomy has evolved in accordance with the physical properties of its diet, and multiple features on each tooth have specific functions related to the breakdown of food during mastication and ingestion. Tooth structure is under tight genetic control and much of the anatomical variation in dentition across species is related to adaptation to a specific dietary regime. This diet-dentition relationship can be exploited to reconstruct mammalian diets from fossil specimens through calculation of dental topographic metrics. To date, most studies of dietary reconstruction using dental topography have focused on mandibular molars; thus, this study seeks to test whether ...


The Effects Of Salinity On Zootechnical Performance Of Spotted Seatrout (Cynoscion Nebulosus) In Recirculating Aquaculture Systems, Eric Gigli Apr 2019

The Effects Of Salinity On Zootechnical Performance Of Spotted Seatrout (Cynoscion Nebulosus) In Recirculating Aquaculture Systems, Eric Gigli

Master's Theses

The spotted seatrout (Cynoscion nebulosus) is a euryhaline finfish candidate for marine aquaculture in the northern Gulf of Mexico. Aquaculture of this species currently uses salinities of 25 psu or greater making production challenging in areas where high salinity water is not available. This study aimed to document the effects of salinity on zootechnical performance of spotted seatrout embryos, early larvae, and juveniles in recirculating aquaculture systems to assist with the development of protocols for low salinity culture.

Embryos obtained from a volitional spawn at 29 psu were incubated at three salinities (12.5, 18.75, or 25 psu) until ...


Critical Embodied Praxis For Social Justice And Peace Educators: A Story Of Personal Transformation Through Analysis Of My Jewish And Settler Identities, Cara Michelle Silverberg Apr 2019

Critical Embodied Praxis For Social Justice And Peace Educators: A Story Of Personal Transformation Through Analysis Of My Jewish And Settler Identities, Cara Michelle Silverberg

Capstone Collection

In this paper, I examine definitions of and relationships between violence, oppression, peace, liberation, and embodiment in the context of critical pedagogy in order to construct a theory of critical embodied praxis for social justice and peace educators. Considering the body to be a tangible vessel through which narratives and mechanisms of violence are expressed and maintained, I explore the potential of the body to be a vessel through which liberatory narratives may be generated and shared. After constructing a theory of critical embodied praxis, I illustrate this framework in action through a personal narrative that explores the intersections of ...


Predators Select For Higher Levels Of Brain Cell Proliferation In Trinidadian Killifish, Rivulus Hartii, Joshua Corbo Apr 2019

Predators Select For Higher Levels Of Brain Cell Proliferation In Trinidadian Killifish, Rivulus Hartii, Joshua Corbo

Senior Theses and Projects

Brain cell proliferation is an important form of brain plasticity that has been sparsely studied in natural populations. Killifish, Rivulus hartii, from the freshwater streams of Trinidad are a remarkable organism for understanding how brain plasticity is influenced by both internal and environmental factors. Through extensive ecological studies in the region, Trinidadian killifish have been used to determine how predation directly effects brain cell proliferation and brain size. In wild populations, waterfalls in the streams block predator movements upstream, thereby creating distinct populations of killifish – i.e., killifish living with abundant predators (high predators, HP) and killifish living with no ...


Effects Of A Postural Restoration Focused Intervention On Muscle Activation During Deadlifts, Caleb Richardson Apr 2019

Effects Of A Postural Restoration Focused Intervention On Muscle Activation During Deadlifts, Caleb Richardson

Human Movement Sciences Theses & Dissertations

The purpose of this study was to determine the efficacy of implementing two Postural Restoration exercises and relating principles on deadlifts using a hexagonal barbell. Specifically, we aimed to examine the effects of the intervention on muscle activation and the location of the ground reaction force (GRF) center of pressure. Sixteen subjects (age 18-35 yrs.; male (n=14); female (n=2)), with at least 1 year of deadlifting experience, were randomly assigned into a control and intervention group (both n=8). Both groups performed two sets of three repetitions of deadlifts at 50% and at 80% of their estimated one ...
