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 …

Self-Determination Theory And Exercise Performance For Individuals With Autism., Martin Calderon

Cal Poly Humboldt theses and projects

Individuals with Autism Spectrum Disorder (ASD) tend to demonstrate low levels of physical activity and exercise when compared to their developing peers. Low physical activity levels are associated with multiple factors, including lack of understanding of how to perform exercise movements and low intrinsic motivation. Token economy reward systems have shown to be practical in behavior analysis for changing behaviors however, there is limited research on the effects of token economy reward systems in an exercise setting. The purpose of this study was to determine the impact of a token economy board combined with self-determination theory (SDT) on the exercise …

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 …

Carbohydrates And Endurance Exercise: A Narrative Review Of A Food First Approach, Alireza Naderi, Nathan Gobbi, Ajmol Ali, Erfan Berjisian, Amin Hamidvand, Scott C. Forbes, Majid S. Koozehchian, Raci Karayigit, Bryan Saunders

Research, Publications & Creative Work

Carbohydrate (CHO) supplements such as bars, gels, drinks and powders have become ubiquitous as effective evidence-based CHO sources that improve endurance exercise performance. However, athletes are increasingly turning to more cost-effective ‘food-first’ approaches for CHO ingestion to improve exercise performance. Mixed CHO foods including cooked lentils, oats, honey, raisins, rice, and potatoes are all effective pre-exercise CHO food sources. Caution is advised when selecting some of these foods as a primary CHO source, as some athletes may be prone to gastrointestinal discomfort—especially regarding those foods where the quantities required for recommended CHO intake may be voluminous (e.g., potatoes). Palatability may …

A Comparison Of Virtual Vs. Traditional Cycling Exercise On Perceived Duration And Exercise Enjoyment, Kyle W. Reason

Dissertations

We compared perceived duration, ratings of enjoyment and RPE between virtual vs. standard cycling. Participants completed a VO2 peak test and four counterbalanced trials (two 20-min, two 40-min) one at each duration on the interactive Expresso bike (EXP) and a workload matched trial on a Velotron (VEL). Acute RPE were assessed every 5-min. Perceived duration (min) and exercise enjoyment were assessed 15-min post. No significant differences were found for perceived duration between trials (SDE 23.9 ± 8.4; SDV 27.1 ± 9.6; LDE 40.0 ± 12.1; LDV 38.9 ± 10.8). For long duration expresso (LDE) RPE-overall were significantly lower at 25, …

Single-Leg Cycling To Maintain And Improve Function In Healthy And Clinical Populations, C. Eric Heidorn, Steve Elmer, Kyle W. Wehmanen, James C. Martin, John Mcdaniel

Michigan Tech Publications, Part 1

Exercise with reduced muscle mass facilitates greater muscle-specific adaptations than training with larger muscle mass. The smaller active muscle mass can demand a greater portion of cardiac output which allows muscle(s) to perform greater work and subsequently elicit robust physiological adaptations that improve health and fitness. One reduced active muscle mass exercise that can promote greater positive physiological adaptations is single-leg cycling (SLC). Specifically, SLC confines the cycling exercise to a smaller muscle mass resulting in greater limb specific blood flow (i.e., blood flow is no longer “shared” by both legs) which allows the individual to exercise at a greater …

The Influence Of Decorin, A Potential Pro-Inflammatory Stimulant, On The Mechanical Properties Of The Annulus Fibrosus, Sabrina Sinopoli

Theses and Dissertations (Comprehensive)

Previous literature has investigated the biomechanical properties of various animal models, but few have studied an isolated and intact rat tail annulus fibrosus. Decorin, a class 1 small leucine-rich protein (SLRP) has the potential to trigger an inflammatory environment as previous research has shown that it may stimulate inflammation via the toll-like receptor (TLR) pathway. An increased inflammatory environment can have biomechanical implications for the disc, and so the ability of decorin to stimulate an environment that alters the mechanical properties of the disc was investigated.

The purpose of this study was to investigate the potential of decorin, a proteoglycan …

Association Between Objectively-Measured Sedentary Time And Self-Reported Prescription Medication Use Among Adults: A Pilot Study, Ciarra Ashley Boyne

UNF Graduate Theses and Dissertations

BACKGROUND: Prescription medication use and extended sedentary time are independently related to poor health outcomes (e.g., diabetes, metabolic syndrome, mortality). Historically, survey methods have been used to obtain estimates of total sedentary time (ST), however, recent use of accelerometers avoids self-report bias and affords more characteristics of ST that may be factors in health outcomes (e.g., frequency and duration of sedentary bouts). The aims of this pilot study were to 1) examine the association between objectively measured ST via accelerometers and self-reported prescription medication use in adults and 2) examine the independent association of sedentary bout length and frequency with …

Inter-Session Repeatability Of Marker-Less Motion Capture Of Treadmill Running Gait, Matthew F. Moran, Isabella C. Rogler, Justin C. Wager

Exercise Science Faculty Publications

Twenty-one experienced runners completed three treadmill running sessions on different days. Each session consisted of three consecutive 2 min trials at self-selected speeds (RPE = 3, 5, and 7). An eight-camera marker-less motion capture system and instrumented pressure treadmill (TM) collected data over the final ~25 s at each speed. Lower extremity joint angles (ankle, knee, and hip) and segmental angles (pelvis and trunk) were computed for each trial with foot contact and toe off being kinematically determined. Spatiotemporal metrics (ground contact time, step length, and cadence) were measured via TM and compared to their kinematically derived counterparts. All spatiotemporal …

Dataset For Effects Of Single-Session Practice Structure On Motor Skill Acquisition And Alpha And Beta Eeg Oscillations, Audrey Porter, Ronald V. Croce, Wayne Smith

Faculty Publications

Although it is known that practicing a motor skill updates the associated internal model, it is still unclear as to how cortical oscillations linked with the motor skill change under differing practice schedules. The current study investigated α- and β-power changes associated with motor skill acquisition. Firstly, we investigated the behavioral effects of practice on motor learning and retention during repetitive (RP) and variable (VP) practice schedules on an anticipation timing task. Secondly, we investigated changes in cortical α (10-13 HZ) and β (15-30 Hz) event-related synchronization and dyssynchronization (ERS/ERD) under RP and VP during early (EP) and late …

Drivers Of Change In Mindfulness- And Acceptance-Based Interventions With Athletes: Investigating The Influence Of Dosage, Readiness, And Attitudes, Thomas O. Minkler

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mindfulness- and Acceptance-based interventions (MABIs) are being used with increasing frequency with sport participants. Research suggests that such interventions may promote sport performance and impact performance-relevant factors, although the current quality and quantity of research is low. Specifically, questions about intervention engagement (i.e., dosage), potentially impacted by stage of change and attitudes toward sport psychology, need clarification. The present study utilized a multi-method, quasi-experimental longitudinal design with female- and male- identified NCAA collegiate athletes to investigate the effects of an MABI. Specifically, one NCAA Division II team (n = 16) and three NCAA Division III teams (n = …

The Immediate Effects Of The Nunee Patellar Support On Individuals With Patellofemoral Pain Syndrome, Nick Linn

Graduate Theses, Dissertations, and Problem Reports (ETD)

Patellofemoral pain syndrome (PFPS) is a common form of anterior knee pain caused by general overuse, muscular weakness or strength imbalances, and poor movement coordination leading to abnormal alignment or mal-tracking of the patella. Recent guidelines do not recommend the use of a knee orthosis due to a lack of evidence supporting their effectiveness. A new patellar support (NuNee, K-Neesio LLC.) which uses distraction force to relieve pressure placed on the patella, has been proposed. The purpose of this study was to examine the immediate effects of the NuNee patellar support on perceived pain, biomechanics, and function in individuals with …

Longitudinal Sport Science Implementation In American Collegiate Men’S Basketball, Jason Stone

Graduate Theses, Dissertations, and Problem Reports (ETD)

The expanding opportunities to implement sport science frameworks in elite-level basketball environments coincide with the sport’s increasing global prominence. Concomitant to these opportunities is the continual growth of the sport technology market (e.g., wearables, force plates) and computational power (e.g., data management tools, coding capabilities), which yields solutions and challenges for both athletes and practitioners. Due to the rapid influx of new sport technologies in high performance environments, particularly American Collegiate Men’s Basketball, more formal and ecologically valid research on how to effectively utilize data derived from them, particularly over long periods of time (i.e., multiple seasons) is needed. To …
