BACKGROUND Many beliefs about obesity persist in the absence of supporting scientific evidence (presumptions); some persist despite contradicting evidence (myths). The promulgation of unsupported beliefs may yield poorly informed policy decisions, inaccurate clinical and public health recommendations, and an unproductive allocation of research resources and may divert attention away from useful, evidence-based information.

METHODS Using Internet searches of popular media and scientific literature, we identified, reviewed, and classified obesity-related myths and presumptions. We also examined facts that are well supported by evidence, with an emphasis on those that have practical implications for public health, policy, or clinical recommendations.

RESULTS We …

Changes In The Activation And Function Of The Ankle Plantar Flexor Muscles Due To Gait Retraining In Chronic Stroke Survivors, Brian A. Knarr, Trisha M. Kesar, Darcy S. Reiman, Stuart A. Binder-Macleod

Journal Articles

Background

A common goal of persons post-stroke is to regain community ambulation. The plantar flexor muscles play an important role in propulsion generation and swing initiation as previous musculoskeletal simulations have shown. The purpose of this study was to demonstrate that simulation results quantifying changes in plantar flexor activation and function in individuals post-stroke were consistent with (1) the purpose of an intervention designed to enhance plantar flexor function and (2) expected muscle function during gait based on previous literature.

Methods

Three-dimensional, forward dynamic simulations were created to determine the changes in model activation and function of the paretic ankle …

Effects Of Two Weeks Of High-Intensity Interval Training (Hiit) On Monocyte Tlr2 And Tlr4 Expression In High Bmi Sedentary Men, Marta Child, Melanie Leggate, Michael Gleeson

International Journal of Exercise Science

International Journal of Exercise Science 6(1) : 81-90, 2013. Monocyte TLR expression has been shown to be reduced after a combination of aerobic and resistance exercise, but more studies considering the influences of different exercise intensities, type and duration on TLR expression are needed. Although there is an agreement about the importance of physical exercise, the minimal amount needed to improve health status is uncertain. Therefore, the aim of this study was to analyse the influence of 2 weeks of high-intensity intermittent exercise training on CD14+ monocyte TLR4 expression in a sedentary, high BMI population. As a secondary purpose, this …

Faculty Research and Creative Activity

Physical activity has a protective effect on brain function in older people. Here, we briefly reviewed the studies and results related to the effects of exercise on cognitive impairment and Alzheimer’s disease. The main findings from the current body of literature indicate positive evidence for structured physical activity (cardiorespiratory and resistance exercise) as a promising non-pharmacological intervention for preventing cognitive decline. More studies are needed to determine the mechanisms involved in this preventative effect, including on strength, cardiorespiratory, and other types of exercise. Thus, the prevention of Alzheimer’s disease may depend on healthy lifestyle habits, such as a structured physical …

Faculty Research and Creative Activity

Pope, ZK, Willardson, JM, and Schoenfeld, BJ. Exercise and blood flow restriction. J Strength Cond Res 27(10): 2914– 2926, 2013—A growing body of research has demonstrated the effectiveness of exercise (low-intensity resistance training, walking, cycling) combined with blood flow restriction (BFR) for increased muscular strength and hypertrophy. The BFR is achieved via the application of external pressure over the proximal portion of the upper or lower extremities. The external pressure applied is sufficient to maintain arterial inflow while occluding venous outflow of blood distal to the occlusion site. With specific reference to low-intensity resistance training, the ability to significantly increase …

The Reality Of Fantasy Sports: A Metaphysical And Ethical Analysis, Chad R. Carlson

Faculty Research and Creative Activity

Fantasy sports have become a major sector of our sport industry. With millions of participants worldwide and billions of dollars generated, fantasy sports have become a fixed part of our sport spectatorship. However, this prevalence has come without much intellectual investigation. Therefore, in this paper I discuss the metaphysics and ethics of fantasy sports. After providing arguments for the consistency of fantasy sports with prominent descriptions of play and games, I compare fantasy sports to other genres of play and games – sports, card games, ‘cybersports’, and spectatorship. After this juxtaposition, I delineate how fantasy sports are different from their …

The Lived Experiences Of Individuals With Acquired Deafblindness: Challenges And The Future, Paula C. Fletcher, Dawn M. Guthrie

Kinesiology and Physical Education Faculty Publications

The lived experiences of seven individuals who are deaf blind (DB) were explored through the use of semi-structured face-to-face interviews. Two of the emerging themes from this phenomenological analysis were: (1) the daily challenges faced by the participants (e.g., difficulties with communication; compromised activities of daily living; lack of independence; and (2) their lack of preparedness for the future resulting from the uncertainties associated with their degenerative diseases. The findings from this study clearly articulate the importance of intervenor services from the perspective of these individuals.

Leveraging Sport Events For Sport Development, Marijke Taks, Laura Misener, Laurence Chalip, B. Christine Green

Kinesiology Publications

It is often claimed that sport events can stimulate interest and consequent participation in sport. The data on this matter are inconclusive. It is known, however, that sport participation is not being raised merely by the fact that an event is being hosted, but rather on the ways that an event is used to render desired effects (i.e., event leveraging). The purpose of this research project was to examine how medium sized sport events can be used to stimulate sport participation in host communities. Using a three-phased study, findings show that: (a) sport events are unlikely in-and-of themselves to generate …

Preliminary Findings: Speed-Accuracy Tradeoff In Windmill Fastball And Change-Up Pitching, Kevin Mcelwee

Undergraduate Review

Little data have been collected that compare the linear velocity of the ball at release versus the accuracy of the pitch in fast-pitch windmill softball pitching. Previous research suggests that accuracy of a task may decrease as the speed of the task increases. Little research exists that previously compares the speed and accuracy of fastball and change-up pitches in windmill softball pitching. These data may assist the batter in decoding the type of pitch being thrown before the ball is released from the pitcher’s hand. It was hypothesized that the slower change-up pitch might be more accurate and the faster …
