The Physiological Responses To Cycling Stress., Moriah Larsen

Skyline - The Big Sky Undergraduate Journal

Background: As the intensity of exercise increases, the risk of incidences for exertional heat illness (EHI) continues to climb. The National Athletic Trainers Association (NATA) has set an official position statement; stating a “gold standard” for obtaining core body temperature is via rectal thermometry. It has been reported that other field-expedient methods of obtaining core body temperature (oral, axillary, tympanic, temporal) are invalid or unreliable sources after intense exercise in hot temperature regions. Purpose: To determine if a relationship exists between rectal temperature measurements and tympanic temperature measurements during intensive long bouts of exercise. Design: Controlled Laboratory Study. Setting: Human ...

Hip Flexor Extensibility And Its Correlation To Hip Hyperextension And Lower Back Pain In Dancers, Tessa Richards

Skyline - The Big Sky Undergraduate Journal

The goal of this research was to measure the correlation between hip flexor extensibility, arabesque height, and lower back pain; specifically, whether a tight iliopsoas group restricts range of motion and correlates with lower back pain in dancers. Through a series of non-invasive measurements, the rectus femoris and iliopsoas group were tested for range of motion and general extensibility. The measurements were as follows: Patrick’s Test, Thomas’s Test, Modified Thomas Test, and prone hip hyperextension. Each subject also completed a pre-screening form to assess degree of lower back pain. The outcomes of the measurements were analyzed to find ...


Leveraging Sport Events For Participation, Marijke Taks, Laura Misener, Laurence Chalip, B. Christine Green 2016 University of Windsor

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

Laura Misener

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 ...

A Comparison Of Cervical And Trunk Musculoskeletal Characteristics Between Female And Male Army Helicopter Pilots, Takashi Nagai, Karen A. Keenan, John P. Abt, Timothy C. Sell, Brian W. Smalley, Michael D. Wirt, Scott M. Lephart

International Journal of Aviation, Aeronautics, and Aerospace

Introduction: Neck pain (NP) and low back pain (LBP) are prevalent among military helicopter pilots. Although there have been few studies on sex differences in the NP/LBP prevalence in this population, females are shown to be at a greater risk of NP/LBP in civilian studies. This disparity may be due to musculoskeletal characteristics differences that predispose females for NP/LBP. The purpose of this study was to compare cervical and trunk musculoskeletal characteristics between male and female pilots. Methods: A total of 8 female pilots (Age: 27.6 ± 4.2yrs, HT: 166.1 ± 7.7cm, WT: 67.9 ...


Inpatient Versus Outpatient Total Hip Arthroplasty, Michael Pollock 2016 The University of Western Ontario

Inpatient Versus Outpatient Total Hip Arthroplasty, Michael Pollock

Electronic Thesis and Dissertation Repository

We conducted a randomized controlled trial to evaluate patients undergoing a total hip arthroplasty (THA) who were discharged from the hospital either on the day of surgery (outpatient) or were admitted overnight following surgery (inpatient). Our primary outcome was the rate of serious adverse events during the first three months postoperatively. Secondary outcome measures included cost, patient satisfaction, functional outcomes, quality of life and pain. We found no statistically significant difference between the two groups in serious adverse events. We found that outpatient THA was less expensive from the perspectives of the hospital and ministry of health; but the difference ...

Dietary Weight Loss Advice In Us Health Magazines And Its Relation To Ancestral Diet, Risa J. Stein, Marium A. Choudhry, Thomas J. Murray Jr.

Journal of Evolution and Health

As rates of overweight and obesity have risen in the US, the public has sought effective strategies for weight loss through dietary modification. A proliferation of processed foods and changing governmental nutrition guidelines have both impacted dietary intake patterns. While physicians are considered respectable sources of weight-loss information, increasingly the public has turned to the media, particularly magazines, for weight loss advice. This study investigated the dietary recommendations found in the five leading US health-related magazines and compared those recommendations to ancestral diets. With a couple notable exceptions, leading health magazines present consistent recommendations for dietary modifications to promote weight ...

Effects Of Static Stretching On Squat Performance In Division I Female Athletes, Clare F. Heisey, J. Derek Kingsley

International Journal of Exercise Science

International Journal of Exercise Science 9(3): 359-367, 2016. Static stretching was once recognized as a method of preparation for physical activity that would inhibit performance and increase risk of injury. However, a growing body of research suggests that static stretching may not have an inhibitory effect. Regardless, the data have not examined gender differences or the fatigue index (FI) and flexibility effects of static stretching on the back squat over multiple sets. Therefore, the purpose of this study was to examine the relationship between a static-stretch condition (SC) and control condition (CC) on flexibility and the FI of Division ...

Individual Differences In The Programming Of Rapid Bimanual Movements: Are Two Modes Better Than One?, Ashley N. Vander Does, David E. Sherwood

International Journal of Exercise Science

International Journal of Exercise Science 9(3): 347-358, 2016. One of the challenges in performing simultaneous bimanual movements is to prevent interference from one limb to the other, thereby maintaining spatial accuracy in both limbs. Prior research has shown that when a longer distance movement is performed with a shorter movement, the shorter movement overshoots its target and the longer movement undershoots its target relative to control conditions where two shorter or two longer movements are made. The current experiment investigated the motor control strategies used by participants when performing simultaneous aiming movements combining both different and same distances. Participants ...
