The Impact Of Impacts: Repetitive Head Impact Exposure In Canadian University Football Players, Jeffrey S. Brooks

Electronic Thesis and Dissertation Repository

Due to the physical nature of the game and repeated head impacts between players each play, the sport of football has one of the highest incidence rates of concussion. With nearly two million participants, this incidence rate translates to a reserved estimate of 100,000 concussions per year due to the contact nature of the sport. Injury thresholds have proven difficult to establish, so American football concussion research has shifted focus to measuring the accumulation of repetitive head impacts. As there are numerous rule differences between Canadian and American football, head impact exposure may present differently for Canadian players. Accordingly, the …

Quantifying The Inter-Relationships Amongst Muscle Blood Flow, O2 Uptake And Muscle Deoxygenation Kinetics From Elevated Baseline Metabolic Rates And Increasing Work Rate Amplitudes, Lorenzo Love

Electronic Thesis and Dissertation Repository

Upon an instantaneous increase in work rate (WR), pulmonary O₂ uptake (V̇O_2p) increases in an exponential-like manner towards a new steady-state. To support this increase in V̇O_2p there is an increase in blood flow (BF; O₂ delivery) to the muscle. Previous research has shown that the rate of this increase in V̇O_2p (which defines V̇O_2p kinetics) becomes progressively slower with increasing baseline WR (WR_bl). Given the paucity of research on blood flow dynamics and underlying muscle metabolic rate, this thesis examined the effect of metabolic rate on the dynamics and relationships …

No Changes In Appetite-Related Hormones Following Swimming And Cycling Exercise Interventions In Adults With Obesity, Brandon G. Fico, Mohammed Alkatan, Hirofumi Tanaka

International Journal of Exercise Science

International Journal of Exercise Science 13(2): 1819-1825, 2020. Swimming is a favorable and ideal modality of exercise for individuals with obesity and arthritis as it encompasses a minimal weight-bearing stress and a reduced heat load. However, the available evidence indicates that regular swimming may not be effective in reducing body weight and body fatness. A current hypothesis is that exercise in cold water stimulates appetite. We determined the effect of swimming training on appetite-related hormones. Thirty-nine adults with obesity and osteoarthritis were randomly assigned to 12 weeks of supervised swimming or cycling training. In the initial few weeks, participants exercised …

Changes In Lifeguards’ Hazard Detection And Eye Movements With Experience: Is One Season Enough?, Jennifer Smith, Geoff Long, Peter Dawes, Oliver Runswick, Michael J. Tipton

International Journal of Aquatic Research and Education

Surveillance is key to the lifesaving capability of lifeguards. Experienced personnel consistently display enhanced hazard detection capabilities compared to less experienced counterparts. However, the mechanisms which underpin this effect and the time it takes to develop these skills are not understood. We hypothesized that, after one season of experience, the number of hazards detected by, and eye movements of, less experienced lifeguards (LEL) would more closely approximate experienced lifeguards (EL). The LEL watched ‘beach scene’ videos at the beginning and end of their first season. The number of hazards detected and eye-movement data were collected and compared to the EL …

A Comparison Of United States Marine Corps Physical Fitness Test And Combat Fitness Test Results, Marc Keefer, Mark Debeliso

International Journal of Exercise Science

International Journal of Exercise Science 13(4): 1741-1755, 2020. The United States Marines Corps (USMC) have installed a Physical Fitness Test (PFT) to measure physical fitness levels and a Combat Fitness Test (CFT) to assess a Marine’s functional fitness as it relates to the demands of combat operations. The PFT involves three events; pull-ups/push-ups (PU), two-minute abdominal crunches/sit-ups (AC), and a timed three-mile run (RUN). The CFT also involves three events; Movement to Contact (MTC), two-minute Ammunition Lift (AL), and Maneuver-Under-Fire (MANUF). It is of interest to determine if the PFT and CFT are both necessary. As such, the purpose of …
