Biomechanical Energetics Of Terrestrial Locomotion In California Sea Lions, Sarah Kerr 2021 West Chester University of Pennsylvania

Biomechanical Energetics Of Terrestrial Locomotion In California Sea Lions, Sarah Kerr

Biology Student Work

Pinnipedia, an order of semi-aquatic marine mammals, adapted a body design to locomote both aquatically and terrestrially. The limbs of these amphibious mammals are modified as flippers, which are beneficial for aquatic locomotion, but can limit their locomotion on land. Phocids (true seals) have reduced forelimbs and are unable to bring their hindlimbs beneath them during terrestrial locomotion. Otariids, like the California sea lion (Zalophus californianus), have enlarged forelimbs and can bring their hindlimbs under the body to locomote quadrupedally on land. Due to these differences, phocids are expected to move on land with greater energetic costs compared to otariids ...

An Annual Training Plan For Collegiate Dance, Ashley R. German

Honors Thesis

The focus of this thesis is on developing an annual resistance training plan for collegiate dance with no test subjects. This project provides biomechanical, physiological, and injury analysis of collegiate dance. Based on the analysis, a research-based, linear resistance training program for the University of South Dakota Dance Team was created. The resistance training program follows basic strength and conditioning principles including specificity, overload, and periodization. Additionally, exercise selection, order, volume, and intensity were prescribed based on standards set forth by the National Strength and Conditioning Association. Generally, from off-season to in-season, exercises moved from general to specific, along with ...


An Emg Optimization Model Of The Kinetic Demands On The Lower Back During Asymmetrical Gait And Load Carriage, Jacob J. Banks 2021 University of Massachusetts Amherst

An Emg Optimization Model Of The Kinetic Demands On The Lower Back During Asymmetrical Gait And Load Carriage, Jacob J. Banks

Doctoral Dissertations

Gait asymmetries are associated with a high incidence of lower back pain (LBP). Although there are several causes of gait asymmetry (i.e. amputation, injury, or deformities), lower back kinetic demands have not been quantified and suitably compared due to experimental limitations in these clinical populations. Further, the impact of gait asymmetry on lower back demands during carrying tasks has not been established. This dissertation addressed these issues by artificially and safely inducing gait asymmetry in healthy able-bodied participants during walking and carrying tasks. LBP risk was assessed by L5/S1 vertebral joint force levels estimated with an OpenSim musculoskeletal ...

Using Machine Learning To Quantify Transverse Plane Lumbopelvic Rhythm, Seth Higgins, Joshua Tome, Rumit Singh Kakar 2021 Old Dominion University

Using Machine Learning To Quantify Transverse Plane Lumbopelvic Rhythm, Seth Higgins, Joshua Tome, Rumit Singh Kakar

College of Health Sciences Posters

Lumbopelvic rhythm illustrates the relative motion between the lumbar spine and pelvis during various activities and could be used as a biomarker for low back pain (LBP). Sagittal plane lumbopelvic rhythm has been extensively examined as a surrogate to measure low back pain risk factor, but trunk rotation, the second component of lifting is commonly missed. Since lumbopelvic rhythm are time series and not discrete variables, machine learning may be a viable solution in identifying clusters of patterns for healthy adults. PURPOSE: To categorize healthy lumbopelvic rhythm in the transverse plane using machine learning. METHODS: 80 adults with no history ...

Trunk Kinematics Using Musculoskeletal Modeling During Range Of Motion Tasks, Maryam Moeini, Ruth M. Higgins, Hunter Bennett, Stacie Ringleb

College of Health Sciences Posters

A spine model can be used to predict post-spinal fusion motion needed to perform physical activities in individuals with scoliosis. Full body lumbar spine (FBLS) model (Raabi et al., 2016) allows for modeling lumbar spine and pelvis movement and was validated for jogging. However, like other existing adult spine models, FBLS model does not allow for a motion providing thoracic and spine. Purpose: To adapt the FBLS model for simulating thoracic, lumbar and pelvis motion during trunk rotation in all 3 planes of motion. Methods: Since T12-L1 in FBLS model is designed as a dependent joint (axial rotation analogous to ...


Self-Selected Maximum But Not Jogging Speed Decreases With Age In Male And Female Runners, Heather Hamilton, Rumit Singh Kakar 2021 Old Dominion University

Self-Selected Maximum But Not Jogging Speed Decreases With Age In Male And Female Runners, Heather Hamilton, Rumit Singh Kakar

College of Health Sciences Posters

Introduction: Running velocity decreases with age, likely resulting from physiological and musculoskeletal changes associated with aging. Females experience a more rapid decline in physical performance during middle age than males, therefore it is important to consider separate-sex analyses when studying running biomechanics and running-related injury. The purpose of this study was to determine the relationship between age and different running speeds separately for female and male runners.

Methods: Male (n=33) and female (n=46) runners (ages 18–65 years) ran at their self-selected JOG (long distance) and MAX (maximal running) pace on a treadmill. Running velocity was recorded. Simple ...

Musculoskeletal Modeling Of The Pelvis And Lumbar Spine During Running, Ruth Higgins, Maryam Moeini, Hunter Bennett, Stacie Ringleb

College of Engineering & Technology (Batten) Posters

Musculoskeletal modeling provides an alternative to in-vivo characteristics that are difficult to directly measure for movements such as running, especially for trunk muscles and joints. The full-body-lumbar-spine (FBLS) model by Raabe and Chaudhari, 2016 is an OpenSim model created for simulations of jogging. The lifting full-body (LFB) model by Beaucage-Gauvreau et al., 2018 is an adaptation of the FBLS created for estimating spinal loads during lifting. PURPOSE: Determine validity of the FBLS and LFB models in simulating pelvis and lumbar spine kinematics during running. METHODS: Inverse Kinematics were executed using experimental data for the FBLS and LFB models. To obtain ...

Measuring Freezing Of Gait During Daily-Life: An Open-Source, Wearable Sensors Approach, Martina Mancini, Vrutangkumar V. Shah, Samuel Stuart, Carolin Curtze, Fay B. Horak, Delaram Safarpour, John G. Nutt

Journal Articles

Background

Although a growing number of studies focus on the measurement and detection of freezing of gait (FoG) in laboratory settings, only a few studies have attempted to measure FoG during daily life with body-worn sensors. Here, we presented a novel algorithm to detect FoG in a group of people with Parkinson’s disease (PD) in the laboratory (Study I) and extended the algorithm in a second cohort of people with PD at home during daily life (Study II).

Methods

In Study I, we described of our novel FoG detection algorithm based on five inertial sensors attached to the feet ...


Power Amplification Strategies Across Animals, Rayhan Asif 2021 The University of Akron

Power Amplification Strategies Across Animals, Rayhan Asif

Williams Honors College, Honors Research Projects

Animals use muscles for movement, but some have evolved mechanisms to exceed maximum power used in a motion known as power amplification. In this literature review, I analyzed and compared the evolution of structures capable of power amplification between species. Structures capable of power amplification were broken down into the basic components of the engine, amplifier, and tool. The species analyzed were found to possess necessary structures for power amplification which were relatively similar to each other in morphology, but varied greatly in function. The ease with which these structures evolved was evaluated based on the amount of divergence which ...

Long-Term Disability Following A Hamstring Injury, Savannah Mclain

Electronic Theses and Dissertations

PURPOSE: Injuries to the hamstring complex are one of the most commonly seen lower extremity injuries in athletic populations. It is currently unknown how psychological or sociological factors affect an athlete after the recovery process has ended and if these factors play a role in re-injury rates relating to the hamstring. It is also unknown if athlete confidence level changes while in a fatigued state after an athlete returns to play from a hamstring injury. METHODS: Twenty-six physically active adults with and without a previous hamstring injury were recruited for this study. Participants completed a Qualtrics survey that included demographic ...


Biomechanics Of The Lower Back During Repetitive Deadlifts, With And Without Body Armor, Vanessa J. Ramirez 2021 University of Kentucky

Biomechanics Of The Lower Back During Repetitive Deadlifts, With And Without Body Armor, Vanessa J. Ramirez

Theses and Dissertations--Kinesiology and Health Promotion

Background: Low back pain is a significant problem and one of the primary musculoskeletal-related conditions affecting active-duty service members [1]. Since more than two-thirds of U.S. soldier occupational tasks involve lifting from floor level to waist height [2], increasing individual lifting capacity is strongly correlated with performance with these tasks [3]. Training for the first Army Combat Fitness Test event (3RM deadlift) to improve lifting capacity directly relates to performing carrying/lifting military tasks. One training modality that can be used in training programs to improve lifting capacity is repetitions-to-failure (RTF) or repetitive lifting to volitional failure [4-8]. RTF ...


Upper Extremity Kinematics And Pain Outcomes During Activities Of Daily Living In Pediatric Hypermobile Ehlers-Danlos Syndrome, Olivia Yanez Wilwert 2020 University of Wisconsin-Milwaukee

Upper Extremity Kinematics And Pain Outcomes During Activities Of Daily Living In Pediatric Hypermobile Ehlers-Danlos Syndrome, Olivia Yanez Wilwert

Theses and Dissertations

Ehlers-Danlos syndrome (EDS) is a group of heritable connective tissue disorders, consisting of thirteen different subtypes. Among the thirteen, Hypermobile Ehlers Danlos Syndrome (hEDS) is the most common. Individuals with this condition present with frequent joint instability that results in ongoing subluxations and dislocations. Secondary diagnoses of this condition include chronic pain, Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), Major Depressive Disorder (MDD), and Generalized Anxiety Disorder (GAD). The diagnostic process of hEDS is convoluted by the lack of a genetic identifier (Malfait et al., 2017). Individuals with hEDS are often not diagnosed until later in adulthood, leaving their adolescent ...
