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 …

Regression Analysis Of Pacing When Running A Marathon, Hawkin Starke

Industrial Engineering Undergraduate Honors Theses

Regression analysis can be an effective way of examining performance in the marathon event. By splitting up the race into segments or in runner terminology “splits” the significance of each segment as it relates to the total finish time can be explored. Because the idea of splits is already ingrained into the minds of runners, it makes intuitive sense to use these as the metrics to define a race. Additionally, marathons generally make participant age and gender date publicly available which can then be used to find trends within specific demographics. This tailors trends to smaller groups of people, making …

The Effects Of A Loaded Pre-Competition Activity Using Tethered Swimming On 25-Yard Swim Sprint Performance 2021, Jacob Burchfield

Master's Theses

Warmup is a standard practice for swim competitions, but there is minimal scientific evidence regarding the effectiveness of pre-competition activities (PCA) after the swim warmup. This study examined whether a loaded PCA using tethered swimming while attached to a power rack improves performance in a 25-yard swim sprint. Post activation performance enhancement (PAPE) may be the proposed mechanism for improvement resulting from a loaded PCA. To determine if PAPE existed following the loaded PCA, varsity swimmers from SUNY Cortland performed a 25-yard sprint a loaded PCA and after an unloaded PCA (control). All participants performed a standard meet warmup (1600-yards) …

Improving The Specificity Of Vertical Stiffness Measurement In Depth Jump Landings, Miles Mercer

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Greater lower extremity stiffness has been shown to increase bilateral jump height through stretch-shortening cycle optimization. Currently, there are two established methods for estimating vertical stiffness (K_vert) of the human body, which is a variant of lower extremity stiffness. The validity of these methods for estimating K_vert in non-cyclical human movements has been questioned recently due to the complex physiological and neuromotor factors that support stiffness regulation in the muscle-tendon complex. The purpose of the present study was to improve the specificity of K_vert measurement using direct derivation of vertical ground reaction force (GRF) and center …

The Physiological Effects Of Therapy Dogs During Exercise For Sedentary Adults, Josie Lynne Mazzone

Increasing Awareness Amongst Injured Student-Athletes, Daniel Lomeli

Capstone Projects and Master's Theses

The NCAA states that there are around half a million college student athletes in America, and according to the National Athletic Trainers’ Association (2020) ninety percent of them will have a sports related injury some time in their career. Student-athletes compared to non-athletes are less likely to utilize resources and professional assistance (Moulton, Molstad, & Turner 1997). Due to fear of seeming weak, losing training time, judgement from peers or coaches and the appearance of needing any psychological assistance, many athletes are less likely to seek help (Brooks & Bull, 1999). Student Athletes seem to worsen their academic performance as …

Agreement Level Of Running Temporal Measurements, Kinetics, And Force-Time Curves Calculated From Inertial Measurement Units, Austin Smith

Electronic Theses and Dissertations

Inertial measurement units (IMUs) and wearable sensors have enabled athlete monitoring and research to become more ecologically valid due to their small size and low cost. IMUs and accelerometers that are placed on the body close to the point of impact and that record at sufficiently high frequencies have demonstrated the highest validity when measuring temporal gait event moments such as ground contact time (GCT) and flight time (FT) as well as peak forces (PF) during upright running. While the use of IMUs has increased in the sport performance and athlete monitoring realm, the potential of the technology’s ability to …

The Impact Of Female Sport Coaches: Role Models For The Next Generatio, Molly Wilkie

Thinking Matters Symposium

Gender equity in higher education settings, such as academic faculty and admission to graduate schools in medical and STEM fields has been well researched (Ceci & Williams, 2011; Cheryan, 2011; Moss & Racusin, 2012). Based on this previous research, there is a pattern of implicit bias towards female applicants for professorships, as well as admissions to graduate and research positions that results in an imbalance of men and women in these positions. However, less research has been conducted on the gender inequities that exist in another area of higher education, collegiate athletics. The purpose of this project is to identify …

Fitness Testing Parameters For Alpine Ski Racing, James J. Pritchard

Research outputs 2014 to 2021

Alpine ski racing requires high levels of isometric, eccentric, and concentric muscle actions through wide ranges of hip, knee, and ankle mobility. The course duration of ∼ 40 seconds for slalom racing to upward of 2.5 minutes for downhill racing necessitates high levels of anaerobic endurance, aerobic power, and force production to be successful. In addition, due to the highly technical skill aspect of ski racing, neuromuscular coordination is of utmost importance. This review identifies the most effective performance testing methods for alpine ski racing, as well as highlighting their relevance to the physiological parameters of the sport.

He Effects Of Vestibular Rehabilitation On Reaction Time: A Critically Appraised Topic, Christian Miles

Sports Medicine Student Work

In the U.S, mild traumatic brain injuries (mTBI) account for 5-10% of all athletic injuries at the high school and collegiate levels. Following mTBI, reaction time is often delayed, which can increase risk for additional injury. Research shows that vestibular rehabilitation therapy (VRT) for mTBI/concussion can reduce symptoms and reduce recovery time; however, research is limited on the effects of VRT on reaction time. Therefore, the purpose of this research project was to critically appraise current evidence on the effects of VRT on reaction time in patients with an mTBI or concussion. To achieve this objective, I conducted a literature …

The Effect Of Cryotherapy And Inflammation And Myofiber Regeneration Following Skeletal Muscle Injury, Noah Macniven

Sports Medicine Student Work

Cryotherapy is a widely used modality to treat acute skeletal muscle injury. Traditionally, cryotherapy is used immediately following an injury to accelerate the healing process by decreasing pain, inflammation and secondary hypoxic injury. Recent studies conflict with this long-standing practice and have suggested that cryotherapy may actually impair the myofiber regeneration process after muscle injury due to suppression of the inflammatory process. Therefore, delaying the healing process. A critical appraisal was conducted on three studies that have examined the inflammatory markers and markers of muscle regeneration. These studies were conducted over the past five years and have examined the effects …

Alter-G® Treadmill Chamber Pressure At Three Unweighted Conditions In College Age Volunteers, Lauren Roberts, Jacqueline Santaniello

Transformations: Presentation Slides

Lower body positive pressure (LBPP) treadmills utilize an inflatable chamber to provide a range of unweighted conditions for specific rehabilitation or training purposes. This is achieved by pumping air into the chamber, which results in a lower body lift or unweighted condition. Creating an unweighted condition for the user lessens the impact on the lower body during treadmill exercise. Yet, little is known about internal chamber air pressure changes during unweighted conditions and its effect on arterial blood pressure (BP). The purpose of this investigation was to study changes in chamber air pressure (CAP), arterial BP, and heart rate (HR) …

The Influence Of Carbohydrate Ingestion On Peripheral And Central Fatigue During Exercise In Hypoxia: A Narrative Review, Erin Sinai

Seaver College Research And Scholarly Achievement Symposium

Abstract

Hypoxia impairs aerobic performance by accelerating fatiguing processes. These processes may originate from sites either distal (peripheral) or proximal (central) to the neuromuscular junction, though these are not mutually exclusive. Peripheral mechanisms include decrements in muscle glycogen or fluctuations in intramuscular metabolites, whereas central responses commonly refer to reductions in central motor drive elicited by alterations in blood glucose and neurotransmitter concentrations as well as arterial hypoxemia. Hypoxia may accelerate both peripheral and central pathways of fatigue, with the level of hypoxia strongly dictating the degree and primary locus of impairment. As more people journey to hypoxic settings for …
