It is important to evaluate football in Canada as the rules and field size are different than American football, and this may influence the impact exposures. The purpose of this study was to quantify the head impact exposures in youth Canadian football and determine if a season’s worth of impacts could cause impairments in executive function. Players (n=50) had their head impacts recorded using an impact measuring device (GForceTracker) throughout all contact practices and games. A subset of players …

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: …

Journal Articles

The present study tested if the quadratic relationship which exists between stepping frequency and gait dynamics in walking can be generalized to stairmill climbing. 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 …

True North Strong Canada 150: Canadian Identity And Its Contribution To Doping Free Sport, Helena A. Hlas

Electronic Thesis and Dissertation Repository

This thesis, a reflective piece inspired by “Canada 150” events, explores the psychosocial and sociocultural factors surrounding the ongoing evolution of the clean sport movement in Canada. A literature review recounts the critical events in the history of doping, viz. the Ben Johnson scandal, which resulted in a call to overhaul sport culture and realign it with fair play values. Theories in sports philosophy and psychology provide a further understanding of the meaning of sport, and psychosocial factors that are inextricably linked to doping behavior, respectively. The autoethnographic method provides insight into current Canadian values to compare with those in …

Kinesiology and Health Science Faculty Publications

Merely viewing objects within reachable space can activate motor cortical networks and potentiate movement. This holds potential value for smooth interaction with objects in our surroundings, and could offer an advantage for quickly generating targeted hand movements (e.g. grasping a support rail to maintain stability). The present study investigated if viewing a wall-mounted safety handle resulted in automatic activation of motor cortical networks, and if this effect changes with age. Twenty-five young adults (18–30 years) and seventeen older adults (65+ years) were included in this study. Single-pulse, transcranial magnetic stimulation was applied over the motor cortical hand representation of young …

Drowning Prevention: Define And Then Gather Evidence Or Gather Evidence To Define?, Nina J. Nyitrai, Suzi Edwards, Nicholas O'Dwyer

International Journal of Aquatic Research and Education

According to the World Health Organization, drowning fatalities are a neglected public health issue ranked as the third most frequent cause of unintentional death by injury. Data used to record drowning incidents are acknowledged as inaccurate. Recommendations on drowning prevention based on these data are currently not informed by accurate, detailed and reliable evidence. Two modifications to current practice are proposed: 1) an Aquatic Incident Report needs to be developed as an extension of the current workplace incident report to prompt for information commonly not included in current drowning reports; and 2) National Water Safety Plans should be modified to …

Development And Validation Of Hybrid Continuum/Structural Finite Element Model For Evaluating Foot And Ankle Biomechanics, Saif Alrafeek

Dissertations

Bone is composed of two structures: compact bone and spongy bone. Spongy bone porosity highly affects the strength and the physical endurance of bone to carry loads. Most studies use continuum finite element (FE) approaches to model spongy bone and neglect porosity. Neglecting porosity may not efficiently assist orthopaedic surgeons to treat patients who experience bone physical disability. The purpose of this study is to demonstrate an inexpensive approach that simulates spongy bone with more accurate capturing of porosity and less requirements of bone information. The approach is developed through investigating the mechanical characteristics of spongy bone; that is, by …

The Influence Of Time Spent In Beginning And End-State Postures On Grasp Choice, Rachel Modersitzki

Undergraduate Honors Capstone Projects

The choice to end comfortably often requires adoption of uncomfortable beginning states, demonstrating that a sequence of movement is planned in advance of movement onset. Many factors may influence the choice of comfortable end-state postures including the greater precision and speed afforded by postures at joint angle mid-ranges (Short & Cauraugh, 1999). There has been no evaluation of the hypothesis that postures are chosen based on minimizing time spent in postures. Typically, the time spent in beginning and end-states are not explicitly constrained, but the end-state posture is likely held for the longer amount of time due to greater precision …

Human Body Motions Optimization For Able-Bodied Individuals And Prosthesis Users During Activities Of Daily Living Using A Personalized Robot-Human Model, Dimitrios Menychtas

USF Tampa Graduate Theses and Dissertations

Current clinical practice regarding upper body prosthesis prescription and training is lacking a standarized, quantitative method to evaluate the impact of the prosthetic device. The amputee care team typically uses prior experiences to provide prescription and training customized for each individual. As a result, it is quite challenging to determine the right type and fit of a prosthesis and provide appropriate training to properly utilize it early in the process. It is also very difficult to anticipate expected and undesired compensatory motions due to reduced degrees of freedom of a prosthesis user. In an effort to address this, a tool …

Autophagy And Aging: Maintaining The Proteome Through Exercise And Caloric Restriction, Kurt A. Escobar, Nathan H. Cole, Christine M. Mermier, Trisha A. Vandusseldrop

Faculty and Research Publications

Accumulation of dysfunctional and damaged cellular proteins and organelles occursduring aging, resulting in a disruption of cellular homeostasis and progressive degen-eration and increases the risk of cell death. Moderating the accrual of these defunctcomponents is likely a key in the promotion of longevity. While exercise is knownto promote healthy aging and mitigate age‐related pathologies, the molecular under-pinnings of this phenomenon remain largely unclear. However, recent evidencessuggest that exercise modulates the proteome. Similarly, caloric restriction (CR), aknown promoter of lifespan, is understood to augment intracellular protein quality.Autophagy is an evolutionary conserved recycling pathway responsible for thedegradation, then turnover of cellular proteins …

When Coordinating Finger Tapping To A Variable Beat The Variability Scaling Structure Of The Movement And The Cortical Bold Signal Are Both Entrained To The Auditory Stimuli, Steven Harrison, Michael Hough, Kendra K. Schmid, Boman Groff, Nicholas Stergiou

Journal Articles

Rhythmic actions are characterizable as a repeating invariant pattern of movement together with variability taking the form of cycle-to-cycle fluctuations. Variability in behavioral measures is atypically random, and often exhibits serial temporal dependencies and statistical self-similarity in the scaling of variability magnitudes across timescales. Self-similar (i.e. fractal) variability scaling is evident in measures of both brain and behavior. Variability scaling structure can be quantified via the scaling exponent (α) from detrended fluctuation analysis (DFA). Here we study the task of coordinating thumb-finger tapping to the beats of constructed auditory stimuli. We test the hypothesis that variability scaling evident …
