Resistant Potato Starch Supplementation Reduces Serum Histamine Levels In Healthy Adults With Links To Attenuated Intestinal Permeability, Jason R. Bush, Jun Han, Edward C. Deehan, Scott V. Harding, Madhura Maiya, Joshua Baisley, David Schibli, David R. Goodlett

Health & Kinesiology Faculty Publications and Presentations

Histamine from our diet or gut microbes can trigger gastrointestinal disturbances, and resistant potato starch (RPS) has previously been shown to alleviate these symptoms while increasing levels of health-associated bacteria such as Akkermansia through unknown mechanisms. Post hoc exploratory metabolomic analysis of serum amino acid, amine, and carnitine metabolites in participants consuming 3.5 g/day RPS or placebo (n = 48) was performed using liquid chromatography-mass spectrometry to determine whether RPS positively influences histamine metabolism and related parameters. Histamine levels were significantly reduced by RPS treatment, but histamine-degrading enzyme products were unaffected by RPS. RPS also reduced histamine-secreting Haemophilus and Lactobacillus. …

Impact Of Self Determination Theory Amongst Individuals With Autism Spectrum Disorder And Physical Activity: Modifying A Survey, Ruben Guillermo Diaz

Cal Poly Humboldt theses and projects

Prior research has expressed concern for individuals with autism spectrum disorder (ASD), who may be at risk regarding exercise and physical activity due to lack of interest, delays in motor skill development, and/or social impairment. Self Determination theory (SDT) has been suggested as an effective approach for supporting individuals with ASD across a variety of domains. SDT expresses that with the satisfaction of three fundamental psychological needs (autonomy, competence, and relatedness), higher levels of intrinsic motivation will develop which will lead to enhanced development and well-being. While SDT is an effective approach to promoting motivation, it has been suggested that …

The Interaction Of Treadmill Type And Incline Slope On Biomechanics And Muscle Activation During Human Locomotion, Rohit Kundu

Cal Poly Humboldt theses and projects

Treadmills are widely used in biomechanical research. However, variations in treadmill design and running surfaces may affect biomechanical variables such as muscle activation and impact acceleration. In addition, incline walking on treadmills leads to changes in the pattern of muscle activation, particularly at steeper inclines. Despite extensive research on the effects of running surfaces and inclines on biomechanical variables (gait, muscle activation, impact force), the impact of varying treadmill manufacturers on biomechanical variables at high inclines remains unclear. Purpose: To determine whether the type of treadmill deck influences surface electromyography (EMG) patterns and impact accelerations at high incline (20%) walking …

The Relationship Between Gluteus Maximus Activation And Running Kinematics In Recreational Distance Runners, Ricardo Sanchez

Cal Poly Humboldt theses and projects

Within the running community, there are strategies that a trainer will utilize to improve the performance of an athlete. One of these strategies suggests that an increase in activation of the Gluteus Maximus (GM) muscle will result in an increase in the efficiency of runners. The primary purpose of this study was to examine the relationship between GM activation and running kinematics.

Methods: Three female and seven male recreational runners (27±8 yrs) from California Polytechnic State University, Humboldt and the local community. A Pearson product-correlation was used to determine the strength of the relationship between Gluteus Maximus activation and kinematic …

Phasic And Repetitive Self-Touch Differ In Hemodynamic Response In The Prefrontal Cortex–An Fnirs Study, Sabrina Von Au, Ingo Helmich, Simon Kieffer, Hedda Lausberg

Exercise and Sport Studies: Faculty Publications

Introduction: Each individual touches the own body several 100 times a day. While some researchers propose a self-regulatory function of self-touch, others report that self-touching increases nervousness. This controversy appears to be caused by the fact that researchers did not define the kind of self-touch they examined and actually, referred to different types of self-touch. Thus, kinematically defining different types of self-touch, such as phasic (discrete), repetitive, and irregular, and exploring the neural correlates of the different types will provide insight into the neuropsychological function of self-touching behavior. Methods: To this aim, we assessed hemodynamic responses in prefrontal brain areas …

Amphisbaenian Head Movement And Burrowing Forces In Damp Granular Media, Jacob Newell

Williams Honors College, Honors Research Projects

Damp granular media is a difficult environment to study because it is both practically complex and it lacks equations which fully describe its behavior. In this study, an oscillatory lateral head movement and its effects while penetrating damp granular media were tested using a robophysical model. This experimental research was inspired by the burrowing behavior of the clade Amphisbaenia, a group of usually limbless squamates that employ a variety of different burrowing behaviors, but it can apply to a wide range of burrowers. This research could help with both human burrowing technologies and the further investigation of animal behaviors.

A Comparison Of Barriers To Traditional And Home-Based Cardiopulmonary Rehabilitation Participation: Potential Implications For The Maintenance Phase, Erin Rose Madison

Graduate Student Theses, Dissertations, & Professional Papers

Cardiac rehabilitation provides medically supervised therapeutic exercise and multifaceted risk factor modification as a form of secondary prevention for cardiovascular disease, a persistent leading cause of morbidity and mortality in the United States and internationally. Despite robust evidence of compelling patient outcomes, decreased disease recurrence, and the indications from the ACC/AHA endorsing phase II cardiac rehabilitation (CR) as a crucial aspect of recovery from cardiac events and qualifying conditions, CR is widely underutilized. A variety of patient barriers can serve as mitigating factors to CR referral, enrollment, participation, and completion contributing to, in part, the underutilization of CR. Barriers to …

The Accuracy Of Recreational Athletes In Self Detecting Ventilation Threshold During A Maximal Exercise Test, Andrew Biegner

Williams Honors College, Honors Research Projects

INTRODUCTION: Ventilatory threshold (VT) is where minute ventilation (VE) increases nonlinearly with increasing exercise intensity. Prior studies have shown that subjects can recognize VT by changes in breathing during exercise. Teaching recreational athletes to use VT as a training method could result in better quality training. PURPOSE: Determine if recreational athletes can accurately perceive changes in ventilation associated with VT during maximal exercise testing. METHODS: Subjects were recruited (n=20, age= 20.5 ± 1.7 yrs.) to participate in the study. Subjects performed a modified maximal treadmill protocol with gas analysis. Subjects indicated when they noticed a considerable change …

Physiological Responses Between Collegiate Female Athletes Versus Collegiate Female Non-Athletes To Body Image, Nutrition, And Mental Health Inquiries., Molly Mcchesney, Jenna Holloway

Williams Honors College, Honors Research Projects

Participation in college athletics poses numerous demands on young adults. Not only are there academic demands to remain eligible for competition, but there are physical and mental demands that often go unnoticed. With all these demands, it is understandable how one's nutrition, body image, and mental health may go on the back burner, resulting in insufficiencies in all three categories. The results from this study suggest that athletes displayed stronger physiological responses with respect to heart rate and blood pressure when responding to the surveys surrounding the topics of mental health, body image, and nutrition as compared to non-athletes. The …

A Comparison Of Peak Ground Reaction Forces Of Pitches From The Stretch And Windup, Richard D. Edwards

Graduate Theses/Dissertations

Ground reaction forces can help coaches and players understand the lower extremity biomechanics of pitching in baseball. Research has told us that there are repeatable characteristics of ground reaction forces that pitchers produce during a pitch. This study examines the differences in peak ground reaction forces produced from pitching from the stretch versus pitching from the wind-up. Five variables were recorded for each pitch from the push-off leg and the landing leg. Landing forces were then compared to landing forces of the other pitching style and the same comparison was made for the push-off leg. This was achieved by altering …

Phenomenological Study Into The Role Of Self-Efficacy In Minority Student-Athletes' Sport Performance, Tomas A. Singhgolden

Graduate Theses/Dissertations

Self-efficacy is a person’s belief in their ability to successfully complete a task, which can be derived from four sources of information (i.e., past performance, vicarious experience, verbal persuasion, and physiological states). The role of self-efficacy in sporting performance is well documented as being positively associated with enhanced performance across multiple levels of sport (e.g., Olympic, collegiate athletes). Specifically, with collegiate athletes, high levels of reported self-efficacy have resulted in higher performance accomplishments. Although self-efficacy has been researched within sports, there is a dearth of knowledge examining ethnic minority athletes’ perceptions of self-efficacy related to their athletic performance. The aim …

Factors Influencing Hard Running Distances In Ncaa Division I Female Soccer Players, Isaac A. Sam

Dissertations and Theses

As the total distances covered in soccer games have remained relatively constant, the hard running distances covered by players have shown varying changes due to the higher physical demands and dynamics of team running performances. Although factors affecting the total distances covered in a match are multifactorial, no study has specifically examined match performance indicators (MPI) that impact hard running distances (HRD). Consequently, the purpose of this study was to better understand how MPI (hard running efforts, turnovers, minutes played, duels won, duels lost, and pass completions) are associated with HRDs and to investigate how each variable contributes to HRDs …

The Physiological And Psychological Performance Effects Of Multi-Ingredient Pre-Workout Supplements In Females During Resistance Training, Mariah L. Snyder

EWU Masters Thesis Collection

In recent years, the use of supplements to aid resistance training performance has increased, particularly through the consumption of multi-ingredient pre-workout supplements (MIPS). However, limited research exists regarding the efficacy of MIPS on physiological and psychological performance in resistance-trained females.

PURPOSE: To determine the physiological and psychological performance effects of MIPS compared to a placebo and caffeine-only supplement in resistance-trained females.

METHODS: Resistance-trained females (n=10) volunteered for the study. One-repetition maximum (1RM) was established at baseline for leg press (LP) and bench press (BP). A within-groups, double-blind, randomized, and counterbalanced design was used to assign the four supplement drinks (i.e., …

Here, 3D biohybrid conductive systems are developed using fibroblasts or cardiomyocytes integrated with carbon nanotube (CNT) forests that are densified due to interactions with a gelatin coating. CNT forest scaffolds with a height range of 120–240 µm and an average electrical conductivity of 0.6 S/cm are developed and shown to be cytocompatible as evidenced from greater than 89% viability measured by live-dead assay on both cells on day 1. The cells spread on top and …

Time Of Day Effects On Maximal Effort Strength/Power And Fatigability Assessments, Justine Renziehausen

Electronic Theses and Dissertations, 2020-2023

The circadian rhythm is a 24-hour cycle present within most biological systems that is controlled by the suprachiasmatic nucleus (SCN) of the hypothalamus. The SCN is responsible for synchronizing the peripheral "clocks" present in other tissues so that all rhythms, such as heart rate, body temperature, and hormone secretion, are functioning together. As most systems experience a circadian rhythm, physical performance likely does as well. Previous studies have investigated time of day effects on maximal strength, power, and endurance performance, however, factors (e.g., sex, chronotype, age, etc.) have not clearly been distinguished. Additionally, body temperature has been suggested to be …

The Impact Of Single-Gendered Versus Coeducational Physical Education Settings On Female Adolescent Body Image And Self-Esteem: Resisting The Weight Of Body Image And Self-Esteem Issues In Adolescence, Jamison H. Stockslager

EWU Masters Thesis Collection

Resistance training is related to disease prevention, improved health, and positive psychosocial well-being in adults and adolescents. Further, resistance training is positively associated with body image and self-esteem. However, most adolescents do not meet activity guidelines, particularly for resistance training. Schools play an essential role for increasing physical activity. Little is known about the effects of different classroom formats for resistance training, i.e., single-gendered versus coeducational, on body image and self-esteem in female adolescents.

PURPOSE: To determine the effects of single-gendered versus coeducational resistance training on body image and self-esteem in adolescent females. METHODS: High school females (n = 30) …

Association Between Baseline Field Test Performance And Match Physical Performance In D1 Female Soccer Players, Benito Joel Cecenas

Graduate Student Theses, Dissertations, & Professional Papers

Background: Fitness testing is utilized by numerous soccer programs as a means for evaluation of player physical capacity. Previous literature has shown Yo-Yo Intermittent Recovery Test Level 1 (YYIR1) performance is associated with match physical performance in elite adult and youth soccer players. Until now, these relationships have not been investigated in the collegiate soccer setting, despite the YYIR1 being regularly utilized at the collegiate level to determine eligibility for competition, influence playing time, and to assess adaptation to training programs. For these reasons the association between the YYIR1 and match physical performance was investigated in women’s collegiate soccer.

Aims: …

A Picture Worth A Thousand Words: Factors Influencing Disability Accommodations, Alicia E. Martin

Cal Poly Humboldt theses and projects

Because not all disabilities look the same it is difficult to label a person with disabilities just by looking at them. Given that our knowledge, attitudes, and perceptions impact how we interpret our world and our willingness to act, people, including professors, may be biased toward providing accommodations for those with easily recognizable disabilities and biased against those with non-recognizable disabilities, and this may impact the disabled person’s ability to learn. This thesis aims to address whether professors’ disability-related attitudes, perceptions of accommodation reasonableness, and willingness to provide accommodations differ when the disability is recognizable (student is pictured in a …

Validation Of An Emg Submaximal Method To Calibrate A Novel Dynamic Emg-Driven Musculoskeletal Model Of The Trunk: Effects On Model Estimates, Amir H. Eskandari, Farshid Ghezelbash, Aboulfazl Shirazi-Adl, Denis Gagnon, Hakim Mecheri, Christian Larivière

Études primaires

Background

Multijoint EMG-assisted optimization models are reliable tools to predict muscle forces as they account for inter- and intra-individual variations in activation. However, the conventional method of normalizing EMG signals using maximum voluntary contractions (MVCs) is problematic and introduces major limitations. The sub-maximal voluntary contraction (SVC) approaches have been proposed as a remedy, but their performance against the MVC approach needs further validation particularly during dynamic tasks.

Methods

To compare model outcomes between MVC and SVC approaches, nineteen healthy subjects performed a dynamic lifting task with two loading conditions.

Results

Results demonstrated that these two approaches produced highly correlated results …

The Effect Of Tempo On Prone Hamstring Exercise - An Exploration Of Unilateral Bias, Derick A. Anglin

College of Graduate Studies: Theses & Dissertations

Hamstring injuries are common muscle-skeletal injuries with a high recurrence rate. While unmodifiable risk factors (e.g., previous injury) vary, recent evidence has questioned the utility of eccentric exercise in preventing hamstring strains. Furthermore, whether eccentric exercise can transfer to sprinting’s kinetic and kinematic requirements is of question. Therefore, this investigation examines exercise tempo (fast vs. slow eccentric phase), movement strategy (bilateral vs. unilateral), and external load characteristics (coupled vs. independent) bias concentric (CON) and eccentric (ECC) biceps femoris (BF) mean electromyography (mEMG). METHODS: Twenty college-aged students aged 18 – 33 (M = 23.4, SD = 3.12 years) with …

The Debate On Nil: Progress For Female Collegiate Sports?, Stephanie Andrada

Master's Theses

In this study, seven female collegiate athletes from three different women’s sports teams (basketball, gymnastics, and volleyball) from a mid-major, Division-I college were interviewed. The study analyzed the lived experiences that NIL has on these specific female athletes in these particular women’s sports using a qualitative methodology. Three research questions were posed:

1. In what ways does the commercialization of college sports influence the NIL opportunities for these female athletes?
2. Could NIL perpetuate an uneven playing field for these female athletes in competition for limited resources?
3. To what degree do these female college athletes feel that NIL presents opportunities for equitable …
