The Effects Of Quercetin And Citrulline On Nitric Oxide Metabolite Production And Cycling Performance, Jennifer A. Kurtz

Kinesiology Dissertations

There is a growing interest in the use of nutrition and dietary supplements to optimize training and time-trial (TT) cycling performance. Separately, quercetin (Q) and citrulline (CIT) have been used as ergogenic aids to improve oxygen (VO₂) kinetics, perceived effort, and cycling TT performance. However, it is currently unknown whether the combination of Q and CIT can provide additive benefits and further enhance cycling performance. We examined 28-days of Q+CIT supplementation on nitric oxide metabolite production (NO) and several physiological measures relevant to time trial (TT) cycling performance. Forty-eight highly trained cyclists were assigned to one of four …

Subject-Specific Human Knee Fea Models For Transtibial Amputees Vs Control Tibial Cartilage Pressure In Gait, Cycling And Elliptical Training, Ali Yazdkhasti

Master's Theses

Millions of individuals around the globe are impacted by osteoarthritis, which is the prevailing type of arthritis. This condition arises as a result of gradual deterioration of the protective cartilage that safeguards the ends of the bones. This is especially true of transtibial amputees, who have a significantly higher incidence of osteoarthritis of the knee in their intact limb than non-amputees. Engaging in regular physical activity, managing weight effectively, and undergoing specific treatments can potentially slow down the advancement of the disease and enhance pain relief and joint function. Nevertheless, the relationship between the type of exercise and its impact …

Electronic Theses and Dissertations

One of the most significant shifts in the mix of U.S. electricity generation over the past few years has been the rapid expansion of renewable energy resources, especially solar and wind. However, fossil fuels are still necessary to fulfill the world’s energy requirements. Despite efforts to increase the use of renewable energy sources, these sources can be at times unreliable, causing countries around the world to continue to rely on base load units such as coal and natural gas. This decrease in fossil fuels and increase in renewable energy sources presents many complex issues in terms of power system planning, …

Responses To Exercise Anchored To Vigorous Intensity Heart Rates, Djadmann Gustave

Theses and Dissertations--Kinesiology and Health Promotion

Exercise prescription to improve cardiorespiratory endurance (CE) is often based on percentages of the reserve or maximum heart rate (HR_peak) or oxygen consumption rate (V̇O_2peak)that reflect vigorous intensities (77-95% HR_peak, 64-90% V̇O_2peak). These intensities elicit a rating of perceived exertion [RPE] response between 14-17 on the 6-20 Borg Scale. It is recommended that exercise within these ranges be sustained for 20-60min per session. The purposes of this study were to: 1) Determine the metabolic (V̇O₂) and perceptual (RPE) responses as well as the sustainability of exercise (time to exhaustion [T …

Switched Kinematic And Force Control For Lower-Limb Motorized Exoskeletons And Functional Electrical Stimulation, Chen-Hao Chang

Dissertations - ALL

Millions of people experience movement deficits from neurological conditions (NCs) that impair their walking ability and leg function. Exercise-based rehabilitation procedures have shown the potential to facilitate neurological reorganization and functional recovery. Lower-limb powered exoskeletons and motorized ergometers have been combined with functional electrical stimulation (FES) to provide repetitive movement, partially reduce the burden of therapists, improve range of motion, and induce therapeutic benefits. FES evokes artificial muscles contractions and can improve muscle mass and strength, and bone density in people with NCs. Stationary cycling is recommended for individuals who cannot perform load-bearing activities or have increased risks of falling. …

Determining The Effectfs Of Introducing Pseudomonas Putida 3p To Black Soldier Fly (Hermetia Illucens) Gainesville Diet, Rebecca Waters

Theses and Dissertations

With a growing global population, food security and waste management strategies are needed (FAO, 2002b); insects have been promoted for these goals. Black soldier fly larvae (BSFL) are endorsed for their ability in decomposition and use as feed (Bava et al., 2019; Swett Walker, 2018). Studies show the life cycle of BSFL is impacted by bacterial supplementation (Franks et al., 2021; Kooienga et al., 2020). We seek to determine the effects of supplementing BSFL diet with Pseudomonas putida 3P. We conducted two forms of a 10-day bench-top study observing larval mass, frass conversion, C:N content, and ammonia production with supplementation …

The Impact Of First-Person Perspective Text And Images On Drivers’ Comprehension, Learning Judgments, Attitudes, And Intentions Related To Safe Road-Sharing Behaviors, Alexandra Bryson Proaps

Psychology Theses & Dissertations

Drivers and cyclists lack an alignment of road sharing knowledge, attitudes, and expectations, resulting in unnecessary fatalities. Educational countermeasures need to present information that captures drivers’ interest by being personally relevant, facilitate elaboration and synthesis of new information with existing knowledge, and change attitudes, intentions, and behavior. Well-documented health-related communication methods were employed to determine their effectiveness in a transportation domain. Health countermeasure designers use first-person perspective to improve narrative instruction outcomes, based on the Elaboration Likelihood Model (ELM; Petty & Cacioppo, 1986). Exploring narrative perspective-taking as a design tool requires the integration of multiple disciplines.

Our design case stems …

Neuromotor Control Of Eccentric Cycling, Joel Anthony Walsh

University of Wollongong Thesis Collection 2017+

The purpose of this thesis was to investigate and quantify how eccentric (ECC) cycling influences the modulation of the underlying neuromotor mechanisms.

Study one investigated post-exercise changes in global corticospinal excitability (CSE) by eliciting a motor-evoked potential in a non-exercised upper limb muscle following concentric (CON) and ECC cycling. No significant differences in global CSE were shown between CON and ECC cycling. However, individual responses of global CSE varied between cycling modes and time points. The variability likely related unfamiliarity with non-specific workload prescription of, and limited controllability of muscle actions during, ECC cycling.

Study two addressed the controllability of …

Local And Systemic Effects Of Flavonoid Intake With Submaximal Cycling Exercise: A Randomized Controlled Trial, Stephanie Kung

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Moderate to high intensity endurance exercise is a known cause of exercise-induced gastrointestinal syndrome, a condition often associated with intestinal complaints such as discomfort, cramps, and diarrhea. Oftentimes, elevated intestinal inflammation and permeability (a “leaky gut”) are also observed. Previous research has shown that flavonoids, natural compounds found in many fruits and vegetables, may mitigate these exercise-induced effects. In particular, certain cocoa powders contain high levels of flavonoids, and chocolate milk is a good source of protein and sugars for sustaining intense activity. Thus, the purpose of this study was to evaluate the effects of a dairy pre-workout beverage, with …

Self-Regulation Of Boundaries For Thriving, Enrichment, And Balance Across The Work-Nonwork Interface, Shelia A. Hyde

Management Dissertations

This three-essay project explores boundary management and work-nonwork enrichment to explain how thriving in the work domain relates to thriving in the nonwork domain. The Cross-Domain Thriving model proposed in Study 1 theorizes that when employees experience growth and energy at work, they create and deplete resources within and across roles and individual boundary management strategies, role congruency, and ease of transition moderate the degree to which thriving translates into enrichment and/or conflict across roles. Study 2 tested aspects of the cross-domain thriving model and found that neither work nor nonwork thriving was related to increased time-based conflict, but both …

No Winners: Transgender Athletes In Cycling, Max Pratt

Masters Theses

Up until very recently, and in many ways still today, the world of cycling has been reserved for those with privilege. Professional racing has found itself in hot water, carrying gender discrimination, transphobia, and elitism throughout its avenues. Those in power are under constant pressure from all sides to make decisions that influence our entire industry.

This work explores the struggles of transgender and gender nonconforming cyclists in the context of competitive racing. Through documentary and design, we aim to bring these conversations to the forefront of the sport, and visualize what the future of cycling may look like for …

Effects Of Carbohydrate Mouth Rinsing Plus Ingestion On Cycling Time Trial Performance, Henry D. Gebhardt

Electronic Theses and Dissertations

Due to limited glycogen stores, carbohydrate (CHO) consumption during exercise is effective at improving performance in endurance events lasting longer than 90 minutes in duration. Recent research has established that CHO mouth rinsing may improve performance over shorter durations, independent of actual consumption. However, research is lacking in determining if an extended period of mouth rinsing has any additive benefit in conjunction with typical CHO beverage consumption over longer competition durations, where CHO ingestion/consumption is likely warranted. PURPOSE: Determine the effects of CHO mouth rinsing combined with consumption compared to CHO consumption alone on cycling performance. METHODS: Following …

The Embodied Dimensions Of Road Cycling And The Formation Of Gendered Cycling Identities, Lance Robert Barrie

University of Wollongong Thesis Collection 2017+

This thesis aims to offer a better understanding as to why road cycling remains one of Australia’s most popular leisure activities, despite a reported 38 road cyclists killed annually and another 12,000 seriously injured (AIHW, 2019). By investigating cycling sensations of the body and cycling, this thesis responds to calls from feminist geographical scholarship to embraced embodied approaches. Building on feminist readings of the work of Deleuze and Guattari (1987), this thesis offers the concepts of the ‘cycling assemblage’ and ‘cycling refrain’ to help rethink the relationship between mobility, subjectivities and place. Two important implications arise. First, attention is drawn …

The “Balance” team managed to visualize that a strong cycling culture was becoming important in Ireland. Hence our …

Modeling Energy Expenditure And Recovery In Cycling, Vijay Sarthy Mysore Sreedhara

All Dissertations

The power-duration relationship, comprised of the parameters Critical power (CP) and work capacity (ϒ), has been used to model energy expenditure in cycling. For modeling recovery, the W'bal model has been used but lacks validation. Additionally, existing literature has not focused on quantifying or estimating the inherent trial-to-trial variability at the subject level, called the intra-individual variability (IIV), of CP and ϒ, posing challenges in modeling and optimization of performance. Thus, the objectives of this research are (i) to establish a method to quantify the IIV of CP and ϒ as determined from the 3-minute all-out test (3MT), (ii) to …

Efficacy Of A Motivational Video On Heart Rate, Rpe, And Total Work Performed During Stationary Cycling, Hannah Angelella

Undergraduate Theses and Capstone Projects

Sedentary lifestyles are a very common way of life for 21st century Americans. Lack of enjoyment and motivation are two common factors that deter people from engaging in physical activity and exercise on a regular basis (1). However, it has been found that visual stimulation may help motivate or distract from exertion (2–4). The purpose of this study was to compare the effects of watching a motivational video (Tour de France (MV)) versus a calming video (Bob Ross painting (PV)) while cycling. Ten recreationally active subjects from the University of Lynchburg staff, faculty, and student population partook in a within-subjects …

Copenhagenization: The Spread Of The Copenhagen Cycling Gospel; A Case Study In Urban Policy Mobility, Rozaliya Momot

Senior Theses and Projects

Copenhagen is synonymous with biking culture, and is one of the first things people think about in relation to the Danish capital. It has become constructed as a policy model for urban planning, especially for cycling policy, and cities around the world look to it as a "best practice" example. As American cities attempt to change their transportation dynamics and encourage alternate forms of transportation, they increasingly look to cycling as a solution, and refer to Copenhagen as a model. In this thesis, I examine how this model has been packaged and exported by influential Danish consultants and public figures …

The Effects Of Environmental Temperature On High-Intensity Interval Training, Jason R. Boynton

Theses: Doctorates and Masters

Endurance athletes typically spend the large majority of training (> 70%) at low intensities (i.e. below lactate threshold) coupled with short and intermittent bouts of high-intensity exercise or interval training (HIIT). Despite HIIT being a relatively small part of training in terms of duration, it has a substantial effect on the adaptations to endurance training. While it is well-established endurance exercise performance is affected in both hot and cold environmental conditions, the effect ambient temperature (TA; frequently referred to as environmental temperature) has on HIIT as performed by an endurance athlete population is not well understood. Therefore, the overall purpose …

Stationary Exercise Bicycle Instrumentation And Verification Of Opensim Pelvic Residual Loads In Seated Cycling, Bradley Robert Wash

Master's Theses

The study of cycling biomechanics typically requires measurement of pedal loads through force transducer instrumentation. However, analysis of seated cycling often necessitates the additional measurement of the loads exerted on the rider by the seat and handlebars. A stationary exercise bicycle was instrumented with two commercial six-axis force transducers at both the seat and handlebar locations via a custom designed mounting system. The system was tested by applying known forces and moments to the fixtures and proved capable of accurately measuring the loads. Additional data collected from cycling tests were compared to values from the literature to add supporting evidence …
