Filtering Affects The Calculation Of The Largest Lyapunov Exponent, Peter C. Raffalt, Ben Senderling, Nicholas Stergiou

Journal Articles

The calculation of the largest Lyapunov exponent (LyE) requires the reconstruction of the time series in an N-dimensional state space. For this, the time delay (Tau) and embedding dimension (EmD) are estimated using the Average Mutual Information and False Nearest Neighbor algorithms. However, the estimation of these variables (LyE, Tau, EmD) could be compromised by prior filtering of the time series evaluated. Therefore, we investigated the effect of filtering kinematic marker data on the calculation of Tau, EmD and LyE using several different computational codes. Kinematic marker data were recorded from 37 subjects during treadmill walking and filtered using a …

Features Of Acceleration And Angular Velocity Using Thigh Imus During Walking In Water, Koichi Kaneda, Yuji Ohgi, Mark Mckean, Brendan Burkett

International Journal of Aquatic Research and Education

Ten participants were assessed while walking in water and on land with wearable inertial measurement units (IMUs) attached to the right thigh. Longitudinal acceleration, anterior-posterior acceleration, and frontal axis angular velocity were measured at 100 Hz, matched with video analysis sampled at 25 Hz during the walking trials. The longitudinal acceleration showed almost 1 g from initial heel contact to 70% of one cycle, and the anterior-posterior acceleration showed a sinusoidal pattern, synchronizing the approximate posture of the thigh in water. The frontal axis angular velocity fluctuated less while walking in water compared with on land, because thigh motion speed …

The Function Of The Intrinsic Foot Muscles During Turns And Mediolateral Shifts In Balance, Hope E. Kircher

Senior Honors Projects, 2020-current

Purpose: Atrophy of the intrinsic foot muscles (IFM) has been associated with foot deformity, balance deficiencies, and plantar ulceration in patients with diabetes. Nevertheless, little is understood regarding the function of the intrinsic foot muscles responsible for abduction of the toes, and no study has directly assessed the role of the abductors in maintaining mediolateral balance or foot alignment and integrity during turning and other nonlinear activities. The purpose of this study was to determine the activation levels of abductor hallucis (ABDH), abductor digiti minimi (ABDM), the first (PDIO1) and third (PDIO3) dorsal interossei, and flexor digitorum brevis (FDB) during …

Analyzing Change-Of-Direction And The Laterally Resisted Split Squat: Incorporating A Lateral Vector Into The Single Leg Squat, Derek Maddy

Boise State University Theses and Dissertations

Improving change of direction (COD) with the use of strength training has led to mixed results. To date, the modified single leg squat (MSLS) and the bilateral squat (BS) have been successfully used to improve COD, with equal improvement. COD is primarily performed at a 45-75° frontal plane angle; however, the MSLS and BS are performed at a 90° frontal plane angle. Based on the force vector theory, it is proposed that a more mechanically similar strength training exercise, the Laterally Resisted Split Squat (LRSS), be used. The purpose of this study is to compare COD with the LRSS, MSLS, …

The Role Of Protein Degradation In Cancer Cachexia In Female Tumor Bearing Mice, Noah Thomas

Graduate Theses and Dissertations

Background: Cancer is a leading cause of death in the world in which half of the people affected by this disease die from its effects. Cancer-cachexia is a syndrome associated with the significant loss of skeletal muscle mass and function, which cannot be fully reversed by nutritional intervention alone and in turn, impairs the host. Cancer-cachexia affects 50-80% of cancer patients and is a primary cause of death accounting for 20-40% of cancer related deaths. Efforts to reverse the effects of cancer-related cachexia have been largely unsuccessful and have primarily focused on the late stages of CC. Methods: Lewis Lung …

Do Compression Garments Work? The Effect Of Compression Garments On Biomechanical And Physiological Factors, Andrew Craig-Jones

UNLV Theses, Dissertations, Professional Papers, and Capstones

New and innovative technology is consistently being introduced to help runners gain an edge over their competition. One of the more popular ergogenic aids in running today is compression garments. It is estimated that the compression garment market will surpass $5 billion by the year 2022. Despite the popularity, there is no clear consensus as to if or why compression is effective as an ergogenic aid. Although there has been a large variety of variables tested, there is little agreement on any of them as to the effect compression has. It appears as if the rate at which compression is …

Partitioning The Mechanical Cost Of Human Walking: Unveiling Cost Asymmetries For Bionic Technologies, Michael Richard Isaacs

UNLV Theses, Dissertations, Professional Papers, and Capstones

Biomechanics studies over the past 150 years, suggest that animals, including humans, move at speeds that “optimize” their cost of transport. These optimizations can be metabolic, mechanical, or a mixture of the two; however, the consensus on the relationship between metabolic and mechanical cost has been muddied by our current conceptualizations of mechanical cost. Our prior considerations in assessing mechanical cost of transport for animal locomotion often rely upon the exchange of potential and kinetic energy for a rising and falling center of mass that is supported by rigid legs. As a result, our understanding of the mechanical costs associated …

Preliminary Study: Leucine Supplementation Exacerbates Muscle Wasting Independent Of The Ubiquitin-Proteasome System, Katarina Bejarano

Graduate Theses and Dissertations

Cancer cachexia is the rapid, drastic loss of muscle mass associated with cancer and is not reversible by conventional nutritional means (Brown et al., 2018; Brown et al., 2017). It occurs in ~80% of cancer patients and is responsible for 20-40% of cancer-related deaths (Brown et al., 2018; Brown et al., 2017). This condition leaves patients with fatigue, functional impairment, reduced quality of life, and a decrease in survival rates. Cachexia occurs through an imbalance between protein degradation and protein synthesis (Brown et al., 2018), which is associated with inflammation and altered metabolic processes.

Several studies have investigated the effects …

Geometric Visual Illusion Effects On Visual Perception And Visuomotor Control: Emphasis On The Vertical-Horizontal Illusion, Shijun Yan

LSU Doctoral Dissertations

The focus of this dissertation was to explore the effects of potential vertical-horizontal (V-H) illusory influences on perceptuomotor control. As part of this focus, we examined the potential use of separate cortical visual streams: the ventral visual stream for perception and the dorsal visual stream for action. Three studies were conducted to determine the effects of the V-H illusion influences on length estimations using upper limb point-to-point movements and lower limb stepping movements, involving various illusory configurations, movement directions, gaze directions. After a short introduction (Chapter 1) and a more detailed review of existing literature (Chapter 2), we present manuscripts …

Kinematic Analyses Of Parkour Landings From As High As 2.7 Meters, Boyi Dai, Jacob S. Layer, Taylour J. Hinshaw, Ross F. Cook, Janet S. Dufek

Integrated Health Sciences Faculty Research

During landing tasks, forces and moments are generated by the musculoskeletal system at surface contact to progressively decelerate the velocity of the body (Dufek and Bates, 1990; McNitt-Gray, 1993). When landing after a forward jump, the body’s downward velocity must be decelerated by an upward acceleration, while its forward velocity needs to be decelerated by a backward acceleration. Inappropriate landing patterns can cause excessive loading to the body, resulting in musculoskeletal injuries. The anterior cruciate ligament is commonly injured by abnormal landing patterns during athletic activities (Dai et al., 2015b; Krosshaug et al., 2007). Military training also involves jump-landing tasks …

Loading Rate Has Little Influence On Tendon Fascicle Mechanics, Michael V. Rosario, Thomas J. Roberts

Biology Faculty Publications

Mechanically, tendons behave like springs and store energy by stretching in proportion to applied stress. This relationship is potentially modified by the rate at which stress is applied, a phenomenon known as viscosity. Viscoelasticity, the combined effects of elasticity and viscosity, can affect maximum strain, the amount of stored energy, and the proportion of energy recovered (resilience). Previous studies of tendons have investigated the functional effects of viscoelasticity, but not at the intermediate durations of loading that are known to occur in fast locomotor events. In this study, we isolated tendon fascicles from rat tails and performed force-controlled tensile tests …
