International Journal of Exercise Science

International Journal of Exercise Science 11(4): 900-909, 2018. We investigated the validity of a recently developed equation for predicting sprinting times of various tactical loads based upon the performance of a running 3-min all-out exercise test (3MT). Thirteen recreationally trained participants completed the running 3MT to determine critical velocity (CV) and finite running capacity for running velocities exceeding CV (D’). Two subsequent counterbalanced loaded sprints of 800 and 1000 m distances with 20 and 15% of their body mass, respectively, were evaluated. Estimated times (t, sec) for running 800 and 1000 m with a tactical load was derived …

Entraining Chaotic Dynamics: A Novel Movement Sonification Paradigm Could Promote Generalization, Dobromir Dotov, Tom Froese

Journal Articles

Tasks encountered in daily living may have instabilities and more dimensions than are sampled by the senses such as when carrying a cup of coffee and only the surface motion and overall momentum are sensed, not the fluid dynamics. Anticipating non-periodic dynamics is difficult but not impossible because mutual coordination allows for chaotic processes to synchronize to each other and become periodic. A chaotic oscillator with random period and amplitude affords being stabilized onto a periodic trajectory by a weak input if the driver incorporates information about the oscillator. We studied synchronization with predictable and unpredictable stimuli where the unpredictable …

Effect Of Restricted Ankle Mobility On Muscle Reaction Time And Ankle Joint Kinematics To A Simulated Ankle Sprain During Walking In Chronic Ankle Instability Patients, Brandon Winward, Ty Hopkins

Journal of Undergraduate Research

Inversion ankle sprains are common and are caused by sudden inversion stresses during weight-bearing movement which causes the foot to roll under and inward.1 Ankle sprains result in tearing or stretching of ligaments and muscles, which reduces ankle stability.2 After a single ankle sprain, up to 80% of people suffer repeated sprains, which often develop into chronic ankle instability (CAI).3 Research has shown CAI patients often exhibit delayed lower leg muscle reaction time and restricted dorsiflexion range of motion (DROM).2

Effects Of Bingocize® On Quality Of Life, Fall Risk, And Health Knowledge In Community-Dwelling Older Adults, Alyssa Kathryn Dispennette

Masters Theses & Specialist Projects

Quality of life (QOL) is an important aspects of overall well-being in older adults. QOL is associated with functional, physical, and psychological health; all of which can be improved with increased physical activity. A high fall risk is associated with low physical function and QOL. One in four older adults experiences a fall each year, making it necessary to focus public health interventions towards decreasing fall risk and improving QOL in older adults. Bingocize® is a health promotion program designed to promote health, health knowledge, physical activity, and social engagement among older adults. The purpose of this study was to …

Mutual Synchronization And Control Between Artificial Chaotic System And Human, Dobromir Dotov, Tom Froese

Journal Articles

Dexterous assistive devices constitute one of the frontiers for hybrid human-machine systems. Manipulating unstable systems requires task-specific anticipatory dynamics. Learning this dynamics is more difficult when tasks, such as carrying liquid or riding a horse, produce unpredictable, irregular patterns of feedback and have hidden dimensions not projected as sensory feedback. We addressed the issue of coordination with complex systems producing irregular behaviour, with the assumption that mutual coordination allows for non-periodic processes to synchronize and in doing so to become regular. Chaos control gives formal expression to this: chaos can be stabilized onto periodic trajectories provided that the structure of …

Compensatory Hip And Knee Mechanics In Transtibial Amputees During Stair Descent And Directional Task, Mindie Clark

All NMU Master's Theses

This study compared lower limb mechanics in unilateral transtibial amputees and able bodied controls during strenuous activities of daily living (ADL). Seven unilateral transtibial amputee and five matched-abled bodied control participants executed stair descent on a four-step rehabilitation staircase followed by one of two anticipated directional tasks. Force, kinematics and gait parameters were chosen to compare mechanics and stride characteristics between the residual limb, intact limb and able-bodied dominant limb between a straight walking condition and a non linear directional movement (wide-step cutting task). Results indicated that significant compensatory mechanisms occurred in the intact limb, perhaps from decreased load tolerance …

Functional Determination Of A Cervical Spine Joint Coordinate System Via An Optimization Approach, Matthew F. Moran, Paul A. Ullucci, Frank Tudini

Exercise Science Faculty Publications

Abstract of conference presentation. Determination of a subject-specific fixed cervical spine joint coordinate system (JCS) is challenging due to several anatomical constraints. Cervical spine motion (flexion/extension, axial rotation, and lateral bending) is the combined contribution from the occipito-atlanto-axial complex and 2^ndcervical vertebra through the 1^st thoracic vertebra. Additionally, there is a lack of accessible bony landmarks aligning with rotation axes. Several methods of quantifying total cervical spine motion from three-dimensional kinematic data have been previously reported, however, none of the JCS determination methods have utilized an optimization approach. PURPOSE: The purpose of this study was to determine …

Passive Hallux Adduction Decreases Blood Flow To Plantar Fascia, Julia Lorene Dunbar

Theses and Dissertations

Purpose: Due to the vital role that blood flow plays in maintaining tissue health, compromised blood flow can prevent effective tissue healing. An adducted hallux, as often seen inside a narrow shoe, may put passive tension on the abductor hallucis, consequently compressing the lateral plantar artery (LPA) into the calcaneus and thus restricting blood flow. The purpose of this study was to compare blood flow within the LPA before and after passive hallux adduction (PHA). Methods: Forty-five healthy volunteers (20 female, 25 male; age = 24.8 ± 6.8 yr; height = 1.7 ± 0.1 m; weight = 73.4 ± 13.5 …

Gait Alterations And Plantar Pressure In Diabetic Peripheral Neuropathy: A Preliminary Study, Adrienne Dora Henderson

Theses and Dissertations

Background: Despite a lack of consensus on its utility, clinicians have traditionally relied on plantar pressure (PP) to predict ulcer risk and prescribe interventions in individuals with diabetic peripheral neuropathy (DPN). Joint kinematics and kinetics have the potential to contribute to DPN assessment and treatment, however previous studies have not accounted for walking speed nor integrated a full-body analysis with a detailed foot model. Purpose: To assess PP and gait alterations in DPN by controlling walking speed and incorporating a multisegment foot model into a full-body gait analysis. We hypothesize that hip and ankle kinetics will be altered consistent with …

Kinesiology and Nutrition Sciences Faculty Research

Background: Despite the increasing incidence of Achilles tendon (AT) ruptures, there is a lack of information on the possible risks associated with regular running and walking for exercise after an injury. There are some known kinematic gait changes after an AT rupture, especially at the knee. However, it is not clear whether runners with AT ruptures may be at risk for secondary knee injuries during shod or barefoot running/walking. Purpose/Hypothesis: The purpose of this study was to compare the kinematics and kinetics of barefoot walking and barefoot and shod running between athletes with a history of AT ruptures and a …

Design And Testing Of A Passive Prosthetic Ankle Foot Optimized To Mimic An Able-Bodied Gait, Millicent Schlafly

USF Tampa Graduate Theses and Dissertations

Currently there are nearly 2 million people living with limb loss in the United States [1]. Many of these individuals are either transtibial (below knee) or transfemoral (above knee) amputees and require an ankle-foot prosthesis for basic mobility. While there are an abundance of options available for individuals who require an ankle-foot prosthesis, these options fail to mimic an intact ankle when it comes to key evaluation criteria such as range of motion, push-off force, and roll over shape. The roll over shape is created by plotting the center of pressure during a step in a shank-based coordinate system. To …

International Journal of Exercise Science 11(4): 886-899, 2018. Medicine ball interval training (MBIT) has been found to be an effective exercise modality in fitness programs, yet the acute physiological responses to this type of this exercise in youth are unknown. The purpose of this study was to examine the acute cardiometabolic responses to MBIT in children. Fourteen children (mean age 10.1 ± 1.3 yr) were tested for peak oxygen uptake (VO₂peak) on a treadmill and subsequently (> 48 hours later) performed a progressive 10 min MBIT protocol of 5 exercises (EX): standing marches (EX1), alternating lunges (EX2), squat …

Dysregulation Of Tenascin C And Hyaluronic Acid In Aged Skeletal Muscle, Alex Holland, Alan Parcel

Journal of Undergraduate Research

Satellite cells are the progenitor stem cells of skeletal muscle (SM) that reside between the sarcolemma and basal lamina. This space is referred to as the satellite cell niche. Following injury, quiescent satellite cells are activated, proliferate then migrate and fuse to the injured region of muscle to support regeneration (3). Satellite cells in muscle tissue from older subjects migrate at less than half the speed of those in young tissue (2). This may contribute to the diminished regenerative response observed in older subjects. Tenascin C (TNC) has been identified as a de-adhesion protein that is upregulated in the satellite …

Control Of Redundant Pointing Movements Involving The Wrist And Forearm, Garrett R. Dorman, Kevin C. Davis, Allan W. Peaden, Steven K. Charles

Faculty Publications

The musculoskeletal system can move in more ways than are strictly necessary, allowing many tasks to be accomplished with a variety of limb configurations. Why some configurations are preferred has been a focus of motor control research, but most studies have focused on shoulder-elbow or whole-arm movements. This study focuses on movements involving forearm pronation-supination (PS), wrist flexion-extension (FE), and wrist radial-ulnar deviation (RUD), and elucidates how these three degrees of freedom (DOF) combine to perform the common task of pointing, which only requires two DOF. Although pointing is more sensitive to FE and RUD than to PS and could …

Biomimetic Design And Construction Of A Bipedal Walking Robot, Alexander Gabriel Steele

Dissertations and Theses

Human balance and locomotion control is highly complex and not well understood. To understand how the nervous system controls balance and locomotion works, we test how the body responds to controlled perturbations, the results are analyzed, and control models are developed. However, to recreate this system of control there is a need for a robot with human-like kinematics. Unfortunately, such a robotic testbed does not exist despite the numerous applications such a design would have in mobile robotics, healthcare, and prosthetics.

This thesis presents a robotic testbed model of human lower legs. By using MRI and CT scans, I designed …
