Freezing Of Gait: Mechanisms, Mechanics, And Management, Peter S. Myers

Arts & Sciences Graduate Student Theses and Dissertations

Parkinson disease (PD) is a neurodegenerative disease with multiple motor and non-motor symptoms, including postural instability, gait impairments, and cognitive deficits. More than 50% of individuals with PD experience a symptom called freezing of gait (FOG), described as a transient inability to take another step forward. Individuals with PD who experience FOG (freezers) have further postural, gait, and cognitive impairments compared to individuals with PD without FOG (non-freezers). While degeneration of the dopaminergic neurons in the substantia nigra is accepted as the primary etiology of the disease, research shows that the disease has a global impact on the brain, accounting …

Abstract of the DissertationSinging as a Therapeutic Technique toImprove Gait for People with Parkinson DiseasebyElinor Clare HarrisonDoctor of Philosophy in Movement ScienceNeurosciencesWashington University in St. Louis, 2018Professor Gammon Earhart, ChairGait impairment is common in older adults and even more prevalent for people with Parkinson disease (PD). Gait dysfunction is often characterized by reductions in speed, step frequency, and step length. In addition, decreased ability to regulate step length and step frequency may contribute to increased gait variability, making walking less stable and increasing risk for falls. As gait deficits are often resistant to drug therapy, there is a need to …

Psychological Effects And Treatment Of An Injury On An Athlete: Suggested Treatment Plan For Athletic Trainers And Physical Therapist, Odell Miller

Honors Theses

Injuries that force athletes to lose participation in their sport and or training have a tremendous impact on their mental health. Mental health issues can be detrimental, but often times go unnoticed. For example in 2010, Kenny McKinley, a wide receiver for the Denver Broncos, was found dead after killing himself with a gun. After suffering a knee injury, he had become progressively depressed. Investigators reported that there are statements saying that McKinley didn’t know what he would do without football. According to NCAA’s Sports Science Institute (2017), the psychological response to injury can trigger mental health issues such as: …

To accomplish this, we investigated the joint angle dynamics and variability during continuous stairmill climbing at stepping frequencies both above and below the preferred stepping frequency (PSF). Nine subjects performed stairmill climbing at 80, 90, 100, 110 and 120% PSF and treadmill walking at preferred walking speed during which sagittal hip, knee and ankle angles were extracted. Joint angle dynamics were quantified by the largest Lyapunov exponent (LyE) and correlation dimension (CoD). Joint angle variability was …

Optimizing Beat Synchronized Running To Music, Jeska Buhmann, Edith Van Dyck, Dobromir Dotov, Marc Leman, Bart Moens

Journal Articles

The use of music and specifically tempo-matched music has been shown to affect running performance. But can we maximize the synchronization of movements to music and does maximum synchronization influence kinematics and motivation? In this study, we explore the effect of different types of music-to-movement alignment strategies on phase coherence, cadence and motivation. These strategies were compared to a control condition where the music tempo was deliberately not aligned to the running cadence. Results show that without relative phase alignment, a negative mean asynchrony (NMA) of footfall timings with respect to the beats is obtained. This means that footfalls occurred …

The circadian rhythm is on a 24-hour clock that cycles between sleepiness and alertness at regular intervals. The circadian rhythms will affect physiological variables such as heart rate, oxygen consumption and blood pressure which can have a large impact on exercise performance. The Bruce Protocol is a treadmill test used to measure maximal oxygen consumption (VO2max). PURPOSE: The purpose of this study was to evaluate the VO2max, Rate of Perceived Exertion (RPE), Time of exercise (min: sec), and …

The Short Term Effects Of L-Arginine On Blood Lactate Levels And Performance During Submaximal Exercise, Evelyn Wong, Victoria Carter

Kinesiology Student Research - Archive

INTRODUCTION: L-arginine is a non-essential amino acid that is precursor to synthesizing Nitric Oxide (NO). It is responsible for regulating blood pressure and improving exercise efficiency and tolerance, along with improvement in vasodilation. Thus it optimizes blood flow. Increased blood flow to active muscles increases substrate utilization to improve muscle recovery and protein synthesis during and after exercise. This allows for greater removal of metabolites lactate and ammonia that are related to muscle fatigue which inhibit exercise performance. Studies have shown that L-arginine supplementation has been a beneficial treatment for individuals that have hypertension, chronic heart failure, type 2 diabetes, …

The Effect Oral Quercetin Supplementation Has On The Capacity Of Exercise, Aliaa Bekhit, Selin Sosa

Kinesiology Student Research - Archive

INTRODUCTION: Maximal oxygen consumption (VO2 max) is a measure of the body’s total oxygen utilization capacity, or in simpler terms, the capacity for exercise, more specifically oxygen demanding aerobic exercises such as running or cycling since these rely on aerobic rather than anaerobic energy resources. Current research suggests that the antioxidant, anti-inflammatory, flavonoid substance quercetin primarily found in food plants, may be responsible for enhanced exercise capacity as measured by VO2 max. Existing studies test this relationship by administering quercetin supplements to individuals over a short period time and then comparing their pre and post-supplement VO2 max values. PURPOSE: The …

The Effect Of Caffeine On Anaerobic Power, Berenice Villegas

Kinesiology Student Research - Archive

INTRODUCTION: Caffeine is a stimulant used by athletes to help enhance performance. Caffeine has shown to benefit endurance performance in high intensity or power sports. It has been recommended to consume about 200-400 mg of caffeine 20-30 minutes before a workout. Caffeine increases alertness and decreases fatigue due to blockage of adenosine in the brain. During exercise, caffeine consumption causes the body to mobilize fat stores before using glycogen supply. Doing so helps prolong exercise by sparing stored glycogen for later. Caffeine is a drug that causes tolerance to develop quickly and can become more of a maintenance drug for …

The Relationship Between Body Composition And Fitness Parameters, Rachel Agostino

Kinesiology Student Research - Archive

INTRODUCTION: Body composition details the materials that make up the human body. Fat mass primarily functions as insulation and energy storage, but can be detrimental to physical performance when present in excess. Fat-free mass contains muscles and the remainder of substances within the body. Maximal oxygen consumption (VO2max) is the maximum capacity of the body to transport and utilize oxygen during incremental exercise to maximal levels. VO2max correlates with fat-free mass. Power and work can be used to measure the anaerobic system. The amount of muscle mass correlates with the power and work that is produced. PURPOSE: The purpose of …

The Relationship Of Maximal Aerobic Capacity And Body Fat Percentage In Athletes And Non-Athletes, Sandra Mendoza, Rj Williams

Kinesiology Student Research - Archive

INTRODUCTION: Maximal oxygen consumption (VO2max) is the maximum capacity of the body to transport and utilize oxygen during incremental exercise. The relative units are expressed as milliliters of oxygen per kilogram of body weight per minute (ml/kg/min) and the absolute rate is liters of oxygen per minute (L/min). Body Fat percentage is the total mass of fat divided by the total body mass, and multiplied by 100%. It is expressed as a percent value. Research shows that athletes tend to have a lower body fat percentage and a higher VO 2maxas compared to non athletes. PURPOSE: The purpose of this …

The Relationship Between Body Composition And Blood Pressure In College Age Students, Arely Ortiz, Fabiana Villari

Kinesiology Student Research - Archive

INTRODUCTION: Body composition is divided into two components: fat-free mass and fat mass. Fat-free mass includes organs, muscles, bones, blood, and skin which is chemically broken down into water, protein, and bone mineral. Whereas, fat mass would be considered essential or stored fat. A common way to measure body composition is to determine percent of body fat or body mass index (BMI). Many studies suggest that BMI is associated with blood pressure. Unlike measuring percent body fat, BMI does not consider fat-free mass and instead uses the ratio of total body weight to height. Considering fat-free mass when associated to …

The Effect Of A 12-Hour Fast On Maximal Aerobic Performance, Colby Boyko, Madison Helt

Kinesiology Student Research - Archive

Maximum aerobic capacity (VO2max) is an indicator of physical fitness and a measurement of an individual’s ability to transport and utilize oxygen. It is measured in absolute terms in (L/min) and can be normalized with weight in (ml/kg/min). Often times food may not be considered a contributing factor to an individuals VO2max, however, ones diet could have a direct effect on their ability to perform incremental exercise to max. Research suggests fasting may have detrimental effects on individual’s ability to exercise, resulting in a lower VO2max and a quicker time to fatigue.

Effect Of Creatine Supplementation On Anaerobic Power As Determined By Wingate Cycle Ergometer Testing In Men, Sarah Ballinger

Kinesiology Student Research - Archive

INTRODUCTION: Creatine monohydrate is widely available and regularly used by amateur and elite athletes in order to better anaerobic performance. Oral supplementation of Creatine can increase skeletal muscle stores by as much as 20%, especially in those that do not regularly consume meat and fish because although Creatine is produced endogenously by the liver, the body also relies on exogenous sources. Phosphocreatine stores are considered a limiting factor for short duration, high intensity exercise. Augmenting available stores has been shown to decrease the rate of fatigue and increase energy availability to power muscular contraction force for longer durations and aid …
