Understanding alcohol use and recovery in professional hockey: a case study of NHL player Bobby Ryan's stories in media narratives
(2024-08-28) Deslauriers, Paul-Antoine
The objective of the research was to understand alcohol use and recovery meanings and the implications for professional high-profile athlete’s mental health and lives, through a critical exploration of mainstream digital news and sport media narratives. 84 media articles were collected and analyzed about Bobby Ryan’s alcohol use and recovery stories. Ryan is a National Hockey League (NHL) player whose stories received considerable contemporary media attention related to alcohol use and recovery. A thematic narrative analysis was used to explore how the media narratives surrounding Bobby Ryan's alcohol use and recovery shape hockey culture and alcohol use in this sport. The following narrative themes were identified 1) Heroic struggles with alcohol use and mental health, 2) Paradox between mental health and performance, and 3) Beyond the surface of a hockey player/misunderstanding of mental health and alcohol use. The results demonstrate that the mental health of athletes is not a priority for the NHL and that the possibility of joining the player assistance program (NHLPA) reinforces the stigma of mental health in the NHL. Ryan's alcohol use has been linked to his traumatic childhood and decline in performance. The impact of the media (e.g., exposure) and the hegemonic masculinity present in hockey culture may have delayed his request for help. The results of this research demonstrate the importance of studying media to understand the impact of mental health and substance use stigma within the NHL. Expanding the study of media representation of athletes who have experienced trauma and made a spectacular comeback would be a relevant avenue of research to understand the impact of trauma on sports performance. Media studies on mental health and substance use can be a way to encourage athletes living through similar experiences to pursue rehabilitation.
Motherhood journeys on and off the ice: a narrative analysis of digital media stories of professional hockey mothers
(2024-04-09) Hladun, Willa
Feminist scholars have problematized the media’s portrayal of elite athlete mothers for downplaying athletic accomplishments in favor of highlighting motherhood statuses. The focus of this thesis was how the intersectional identities of heterosexual and queer hockey playing athletes as women and mothers are constructed and circulated in sport media. A focused case study of high-profile North American ice hockey players (n=7) was used to examine the social constructions of their identities. 101 stories were gathered, with 32 images accompanying stories. Media stories were subjected to a thematic narrative analysis and theorized using relativist narrative inquiry. The key findings are three narrative themes: be outstanding, a new generation, and queer mothers: they’re just like us! Recommendations are made regarding re-framing stories that uphold patriarchal ideals of motherhood, creating policies in sport that support athlete mothers’ autonomy, and the continued research into athlete mother identity construction using an intersectional lens.
Description des manifestations de la pensée critique des joueurs ivoiriens d’élite de handball : une étude de cas.
(2024-04-19) Aliman, Etchi Marcel
Le but de cette étude de maîtrise est de mieux comprendre le processus de prise de décision des joueurs ivoiriens d’élite de handball sous le prisme de la pensée critique telle que conçue par Lipman. Plusieurs études mentionnent que la prise de décision est un facteur déterminant de la performance en sport. Toutefois, ces études ont été réalisées dans les pays développés et peu d’études empiriques ont été menées en Afrique subsaharienne. Une approche qualitative combinant des entrevues ante et post-match, des entrevues semi- dirigées via la technique de rappel stimulé auprès de huit joueurs a été utilisée. Le corpus recueilli a été traité selon la technique d’analyse de contenu. Les résultats indiquent que le processus de prise de décision s’appuie sur neuf (09) facteurs de la pensée critique incorporant les trois (03) caractéristiques lipmaniennes de cette forme de pensée. La caractéristique « sensibilité au contexte » est la plus convoquée, suivie de la « présence de critères » et rarement « l’autocorrection ».
La pensée critique dans la formation en kinésiologie : un examen des conceptions des formateurs et formatrices universitaires de l'Ontario en regard à sa nature, ses rôles et les modalités de son développement.
(2024-04-03) Savadogo, Aboulaye
Cette étude vise à explorer les conceptions de la pensée critique des formateurs et des formatrices universitaires en kinésiologie de la province de l’Ontario. Plus précisément, elle cherchait à identifier et à décrire leurs conceptions concernant la nature, les rôles et les modalités de développement de la pensée critique. Une méthodologie mixte a été employée. Trente formateurs et formatrices universitaires en kinésiologie de la province de l’Ontario ont volontairement participé à un sondage par questionnaire. Les données recueillies ont été analysées selon la technique de statistique descriptive. Les résultats ont montré des conceptions diverses, alignées sur des perspectives philosophiques, psychologiques, psychopédagogiques, de la théorie critique et de la pédagogie critique. Les enseignant.e.s universitaires considèrent que la pensée critique joue un rôle crucial dans le développement des compétences analytiques et décisionnelles des étudiants. Ils ont indiqué l'utilisation de stratégies d'enseignement multiples et d'études de cas, l'apprentissage par problèmes et les projets pour développer la pensée critique des étudiants. Dans l'ensemble, l'étude a mis en évidence la diversité de conceptions de la pensée critique en kinésiologie et l'importance des approches mixtes pour son développement.
Mixed methods approach for secondary data using survey reports from an exploration industry database
(2023-04-11) Bond, Rebecca
The rich information acquired from incident and near miss reporting has been studied within high-risk industries and such industries have used statistics acquired from past incident reports to reveal trends to improve occupational health and safety. The proposed project aims to understand the specific nature of injury severity reports within Canada’s mineral exploration field to enhance existing occupational health and safety. The proposed research is unique as the data arises from the entire mineral exploration industry in Canada, gathered by Prospectors and Developers Association of Canada (PDAC), to represent a group of companies, working across Canada. Data of this magnitude, over such a long time span, in this workforce, has never been conducted before. Much research in H&S in the mining field has focused on mine workers, not on mineral exploration, due to the difference in numbers. It is difficult to extrapolate knowledge from other fields to mineral exploration, because of its high specialization, creating unique H&S challenges. Although closely linked to production mining, Mineral Exploration requires a different health and safety approach. This workforce has unique health and safety needs that arise due to: the nature of the working environment; remote locations subject to extreme weather and terrain; difficulty recruiting skilled workers in times of economic booms due to production pressures or conflicts of interest between H&S superiors and trainees; lack of available resources in the field which vary and are dependent on financial capacities of each company ; and H&S efforts heavily influenced by a company’s market capitalization meaning smaller companies often times not having one person specifically in charge of H&S or potentially be less obliged to follow or partake in H&S procedures, and in large companies it is more likely to have a whole group whose sole focus is H&S and the environment. Determining which factors influence health and safety within mineral exploration is therefore a crucial first step to better understand the safety culture, safety consciousness, and the specific needs of this field. Given that the health and safety environment of mineral exploration is multidimensional, it is pertinent that research be conducted directly within this field to bridge gaps in prevention and practice. The expected outcome for this project was twofold: i) to highlight the health and safety trends in the industry; and ii) to determine common trends, areas of importance, critical issues, and actionable training suggestions, to mitigate risk for workers. This was done by taking survey data and showcasing points for industry and occupational health and safety advocates through knowledge transfer components, to provide a deeper understanding of various components that contribute to injuries and fatalities.
Examining factors in presenteeism and absenteeism: physical activity rates and mental health related predictors of productivity loss in a mining population
(2022-10-14) Nesbitt, William
Canadian companies are estimated to lose $16 billion in work productivity per year from workers calling in sick due to mental health issues (Mercer, 2018). Impacts in work productivity are commonly reflected in rates of absenteeism and presenteeism. This study uses data gathered on the Mining Mental Health Study to evaluate this issue in a Northern Ontario Mining Population by identifying predictors of mental health-related and physical health-related productivity loss. Previously receiving mental health treatments or taking mental health medication were the leading causes of mental health-related work productivity loss, while a physical disease diagnosis was the leading cause of physical health-related work productivity loss. Depression symptom severity was significant in predicting instances of both absenteeism and presenteeism. Interventions in this population should focus on providing resources to lower depression symptom severity and be peerbased, as to help overcome any existing mental health stigma in this male dominated industry (Sayers et al., 2019).
Muscle temperature influences oxygen uptake and blood flow during single leg isokinetic exercise.
(Laurentian University of Sudbury, 2020-12-02) McCue, Alexus
Thermal changes in muscle tissues (i.e: cooling and heating) modulate local oxygen transport from the muscle and into the cell. Whether a change in skeletal muscle oxygen transport subsequently regulate oxygen consumption (V̇ O2m) and tissue oxygenation (%TSI) during exercise is unclear. The purpose of this study was to assess the effects of skeletal muscle cooling and heating on muscle blood flow (Q̇ mus), V̇ O2m, and %TSI during single-leg isokinetic exercise. Eleven men exercised during 3-min intervals under thermoneutral (TN) condition, and localized muscle heating (HT) and cooling (CO), at 10%, 30%, and 50% of their maximal voluntary contraction (MVC). An occlusion technique combined to near-infrared spectroscopy was used to estimate V̇ O2m and Q̇ mus before and after exercise bouts. The results of this study showed that Q̇ mus was significantly increased in HT, while V̇ O2m was instead decreased in CO. Muscle temperature did not significantly change %TSI during exercise. Moreover, the relationship between Q̇ mus and V̇ O2m (TN: 0.173  0.101, CO: 0.187  0.0655, and HT:0.107  0.0413) was steeper in CO compared to HT (p = 0.009). In conclusion, this study demonstrated that muscle temperature regulates the blood flow/O2 consumption relationship during incremental isokinetic exercise.
Turning concussion management on its head: an exploratory model for managing varsity athletes following a sport-related concussion
(2021-04-26) Smith, Camille R.
The objective of this study was to determine and discuss various relationships between symptoms, Post-concussion Symptom Score and Symptom Severity Score, exercise prescription, and RTL as well as RTP times. These relationships were investigated using a combination of statistical quantitative and qualitative assessments. The study found that some of the symptoms presented were related to one another and predominantly only presented in clusters. It was also found that recovery time generally takes longer than previously reported; more than 30 days vs the previous standard of 14 days until full recovery. Thus, a general guideline with respect to recovery times was created that can be provided to athletes, coaches, and other stakeholders, with the intent of removing some of the external pressures that clinicians face to return athletes to their sport safely and effectively
Validating the remote first aid self-efficacy scale for use in training and personal development of remote first responders
(2021-07-14) D’Angelo, Jonah Joel John
This study was designed to investigate the psychometric properties of the 30-Item Remote First Aid Self-Efficacy Scale (RFA SES), develop a shorter 15-Item RFA-SES, and gain a preliminary understanding of the psychometric properties of the shorter 15-Item version. The original 30- Item RFA SES was developed for two main purposes: (1) evaluation of wilderness first aid and other types of emergency care training designed for remote geographies, communities, and worksites; and (2) reflection by training participants so they can self-assess their beliefs, confidence, and capacity to respond. Students from Laurentian University (LU) and graduates from Wilderness Medical Associates (WMA) training courses were recruited to respond to an online questionnaire at two different time periods (T1 and T2). A total of 1106 students and 448 graduates from WMA responded at T1. These results demonstrated that the RFA SES was a unidimensional scale with an eigenvalue of 18.1 at T1. The mean inter-item correlation was 0.75 at T1. Test-retest reliability (T1 to T2) was high for both the LU group (r = .91, p < .01) and the WMA group (r = .92, p < .01). Moderate correlations were found between the RFA SES and two other similar scales (included in the questionnaire) measuring different constructs. WMA participants showed higher mean scores than LU students at T1 (t (569) = 16.2, p < .01, twotailed). The 30-Item RFA SES is a unidimensional, reliable, and valid scale for assessing remote first aid self-efficacy. To develop the 15-Item RFA SES, three members of the research team completed an iterative process to reduce items based on expert opinion and statistical performance from the inter-item correlations. Preliminary analysis of the 15-item version of the RFA SES, using data from the WMA group (n=448), also indicated that the scale was reliable and valid. However, a more rigorous validation study with original data is required.
Prospective housing decisions and self-determination theory
(2021-04-13) Barbosa, Halana Batistel
The purpose of this study was to understand seniors’ motivation to age in place or change living arrangement using Self-Determination Theory (SDT) as a theoretical framework. Seven seniors were interviewed, and the Satisfaction with Life Scale (SWLS) was applied. By applying a thematic analysis four themes were identified: (1) Basic psychological needs and physical and social surroundings as a factor of aging in place, (2) Health and the feeling of being a burden as a major factor of housing decision, (3) Knowledge about assisted living environment as a reason to age in place, and (4) Feeling of accomplishment and SWLS. Interpreting these results using SDT suggests that intrinsically motivated seniors decided to age in place, and seniors with high intrinsic motivation were satisfied with life. These findings represent an important move towards understanding seniors’ wellbeing since a more holistic and respectful care can be provided to seniors by understanding their motivations about housing decisions.
An exploratory study of post-secondary outdoor leadership training in Canada
(2021-04-14) Williams-Orser, Beau M.
The purpose of this study was to explore the distribution and scope of post-secondary outdoor leadership (OL) training in Canada. Methods included a passive environmental scan to locate programs across Canada, and a multiple case analysis of programs within Ontario. There were 54 programs located in Canada, including university programs (n = 28; 52%) and college programs (n = 26; 48%). Based on analysis of available information, the scope of post-secondary OL training in Canada can be summarized in five themes: Primary and Secondary Education (n = 5; 9.3%), High Adventure Guiding (n = 10; 18.5%), Tourism Management (n = 11; 20.4%), Health and Wellness Promotion (n = 15; 27.8%), and Interdisciplinary (n = 13; 24.1%). The 10 programs in Ontario were presented as multiple case studies. An inductive analysis of learning outcomes from nine of 10 programs led to the development of 14 themes, representing common competencies taught across programs.
An environmental scan of outdoor orientation programs at universities in Canada
(2020-12-07) McGarry, Jeff
As of 2012, colleges and universities in the United States had established 191 outdoor orientation programs (OOPs) and this was increasing at the rate of approximately 10 per year. The situation in Canada has been strikingly different. Little information is available regarding OOPs at universities in Canada and this is true for information available online and in the literature. This study used an environmental scanning (ES) approach to identify information related to OOPs at universities in Canada. During the 2015-2016 academic year, approximately 20% (n=21) of the universities in Canada used OOPs, however only 573 students were participating in Canadian OOPs (COOPs) during the 2017-2018 academic year. The common objectives of COOPs were to: (1) facilitate peer relationships and bonding; (2) connect students to place; and (3) promote student development. The COOPs described in this study represent an underutilized opportunity for a holistic approach to student development and orientation at universities in Canada
Slips trips and falls in Northern Ontario underground hard-rock mines
(2020-08-05) Sherrigton, Chelsea
Underground mining environments are dark, wet, and have uneven terrain that can create a risk for slips, trips, and falls (STFs). Ontario hard-rock mine workers are legally required to wear personal protective equipment (PPE). Underground miners also work in a dark and dusty environment with uneven terrain, many work shiftwork, and many work on or around large equipment. There is limited research on STFs in underground mining (Dobson et al., 2015) and to my knowledge workers in underground hard-rock mines have not been surveyed about their perceptions of STF risk factors. This study was conducted to advance understanding of risk factors for STFs in underground mines in Northern Ontario, with an aim to provide recommendations for underground safety guidelines, training procedures and future research. 152 underground workers from 2 mine sites in Northern Ontario completed a survey regarding STF in underground mining. The survey contained 16 open-ended and 6 closed-ended questions that addressed demographics, working roles, and perceptions of STF risk factors pertaining to personal, environmental, work task and PPE related factors. Closed-ended questions were coded and analyzed in SPSS. Open-ended questions were analyzed using the Braun and Clark. (2019) method of thematic analysis The top 10 identified risk factors included uneven terrain, puddles/holes, poor lighting, slippery surfaces, fatigue, getting in/out of equipment, clutter in the walkway, poor vision, walking long distances, and poor balance. Workers identified work environment as the primary component of STF risk, as 5 of the top 10 risk factors indicated are a sub-set of environmental factors. When asked what contributed to the risk of STF 29 of 152 underground workers discussed housekeeping and maintenance of roadways. 54.6% (n=83) of workers strongly agreed that climbing on/off equipment was also a major risk factor for STFs and ranked it 6 out of 10. Workers also identified fatigue as a risk factor as it was ranked 5 out of 10. 54% (n=82) agreed and 30.3% (n=46) strongly agreed that their personal level of fatigue was a risk factor for STFs. Responses indicated that 80.9% (n=123) and 52% (n=79) of workers felt that they were more likely to experience a STF towards the end of their shift and beginning of their shift respectively. Workers also indicated that they aware of the risk factors in their workplace as 59.3% strongly agreed to this statement. Future research on the top 10 identified risk factors (uneven terrain, puddles/holes, poor lighting, slippery surfaces, fatigue, getting in/out of equipment, clutter in the walkway, poor vision, walking long distances, poor balance) would be beneficial to further understand how each factor affects a worker’s risk of experiencing a STF.
Exploring trail use and the health of students at a university in Canada
(2020-10-28) Friesen, Kimberly Belle
The purpose of this study was to understand trail use patterns and other factors that may contribute to the health and well-being of university students in northeastern Ontario, Canada. Students from Laurentian University (LU) were recruited to participate in an online questionnaire that was distributed via the REDCap software. The questionnaire included the Perceived Stress Scale (PSS), the Flourishing Scale (FS), and the Leisure Time Physical Activity Scale (LTPA). A total of 1,367 students participated in the study which represented approximately 15% of the student body. The findings indicated that students at LU had high levels of stress and psychological well-being. Students who used trails were significantly more likely to have improved mental health, physical health, and physical activity levels. The top two facilitators to trail use were nature appreciation and outdoor recreation and the top two barriers were intrapersonal factors and lack of knowledge. These findings have implications for health promotion opportunities involving outdoor environments, such as trails, at institutions of higher education.
Assessing whole-body vibration transmissibility in children's bicycle trailers
(2020-10-19) Kanya-Forstner, Margaret
The overall objective of this thesis was to assess whole-body vibration (WBV) exposure in bicycle trailers to determine 1) vibration exposure characteristics associated with children riding in bicycle trailers, 2) the effectiveness of the bicycle trailer seat in reducing vibration transmitted to children riding in a bicycle trailer, and 3) to determine if gel seat cushions were effective in reducing vibration transmissibility through the seat/gel cushion to the buttock of a child in a bike trailer. These objectives were accomplished through a field study and a laboratory study. The first study, was conducted in the field with the primary objective to 1) to document vibration exposure characteristics measure on the bicycle trailer frame, at the interface between the seat and buttock of a seated child, and at the back of the child’s head, 2) to determine health risks based on an ISO 2631-1 health guidance caution zone (HCGZ) analysis, and 3) to determine if vibration exposure characteristics differed when riding on gravel compared to a paved terrain. The findings revealed an associated health risk, with levels of vibration measured at the buttock/seat interface consistently exceeded ISO 2631-1 health guidance caution zone guidelines. Moreover, vibration exposure magnitude, and associated health risk, was higher when the bicycle trailer was ridden on gravel terrain at higher speeds. When adjusted for a twohour exposure time, vibration experience by the children sitting in the bicycle trailer, for the majority of the trials, revealed a moderate health risk according to the ISO 2631-1 HGCZ. Additionally, all 12 trials had seat-to-head transmissibility levels above 1.00, indicating an amplification in vibration from the child’s seat to their head when riding in the bicycle trailer. The second study, was conducted under controlled laboratory settings with the aim to determine the impact of independent variables terrain type, trailer type, and cushion type, on dependent variable vibration magnitude measured at the interface between the trailer seat and simulated buttock of a child. Terrain type had the largest influence on vibration exposure levels (p<0.001), followed by trailer type (rigid-frame vs. suspension-frame) (p<0.001). Gel cushions did not significantly influence vibration measured at the seat/buttock interface but were found to reduce vibration measured at the rigid-frame trailer. Findings from this thesis suggest that if children were to spend greater than 2 hours a day in a bicycle trailer, they would exceed the ISO 2631-1 HCGZ, and ultimately be at an increased risk for a vibration-induced injury. Children were also exposed to higher levels of vibration when the bicycle and trailer travelled at a higher speed and travelled over rougher (gravel) terrain. Laboratory analysis found the gel seat pad was not effective at attenuating vibration at the seat. Additional research should be conducted with a larger sample of bicycle trailer types. Furthermore, this study highlighted the need for additional research to determine health risks associated with vibration exposure in young children as current international standards are designed to determine health risks of vibration exposure for health adults in an occupational context.
Measuring differences in eye glance behaviour for heavy equipment operators while driving in naturalistic worksite environments
(2020-08-27) Brunton, Alyssa
Struck-by accidents continue to be a predominant issue with catastrophic consequences in both construction and mining industries. These incidents are found to be largely caused by blind spots due to the equipment or environment, along with human error. Blind spots are considered to be non-visible areas where operator line-of-sight is impeded by parts of the heavy equipment, buildings or other objects in their environment. Eye-tracking (ET) research has mostly focused on the eye behaviour while operating passenger vehicles. This research includes, but is not limited to, eye scanning patterns of drivers, development and implementation vehicle interaction devices for safe use and enhanced education through training programs. Visual scanning patterns of heavy equipment operators cannot be lumped into that of those driving passenger vehicles as the design of various machinery is vastly different in addition to differences of driving on a public road compared to a worksite environment. The intention of this research was to initiate research specifically for ET data while operating various types of heavy equipment. The purpose of this research was to quantify typical heavy equipment operator eye gaze behaviour in natural worksite settings in both construction and mining industries. First, the objective was to determine the similarities on where operators naturally look while driving in a field setting. Key areas of interest (AOI) operators looked were identified during forward and rearward movements. The most noticeable difference was that the front view ahead was fixated the most while driving forwards, whereas the mirrors were tended to the majority of rearward movements basically never looking within the front views. As some heavy equipment, such as a load-haul-dump (LHD) have very unique characteristics including operator seated position within the machine, it was important to measure their visual scanning pattern while driving, especially in an underground mine. Therefore, the second objective was to obtain data to quantify typical LHD operator eye gaze behaviour in addition to determining differences between novice and expert operators. This was accomplished by comparing novice operator completing a four-day training program on an LHD simulator to a similar trial completed by the expert operator. Results demonstrated that visual scanning patterns of the novice operator was considerably more dispersed than that of the expert which was much more focal. However, it should be noted that the scanning pattern of novice operators did become more focal and less dispersed at the end of training, starting to resemble that of the expert. Other main findings revealed that regardless of direction travelled, operators spend the majority of time fixating within the central view ahead. Findings suggest that novice operators experienced an overall decrease in cognitive workload and relied less on using the edge of machine and wall as sightlines to monitor LHD speed and position within the mine as experience increased. Interestingly enough it appears that the expert operator utilized the right wall as a sightline while driving forwards, differing from novice operators. Determining the gaze behaviour of heavy equipment operators on various machines is important to have a baseline typical eye gaze behaviour to be able to detect deviations that can provide a measure of how technologies, policies or training programs affect gaze behaviour. Eye gaze behaviour needs to be incorporated in the design of future technologies (ex. proximity detection and awareness technology) to provide modifications to reduce cognitive workload and distraction that can occur when implementing devices. Findings of this research could also aid to enhance current training programs and advise the development of new training programs or policies to minimize human-equipment interactions.
The determinants of sleep quality in the mining industry
(2020-04-27) Dennie, Alexie
The purpose of this study was to determine the current state of self-reported sleep quality in workers of the mining industry and identify the factors that affect sleep in this sample. A large-scale questionnaire was administered to 2,224 workers of the mining industry with operations in Ontario. A modified version of the Pittsburgh Sleep Quality Index (mPSQI) was used to determine sleep quality and quantity. A total of 84% of participants self-reported poor sleep quality with an average mPSQI score of 6.43 (± 3.07). The average sleep duration of participants was 6hr:05min (± 1hr:03min), which is lower than the recommended 7-8 hrs of sleep. Participants engaging in hazardous drug and alcohol use, screening positive for mental health concerns, stress and fatigue, experiencing workplace burnout and working shifts, self-reported worst sleep quality. Finally, depression, personal burnout, fatigue, PTSD, shift work, diagnosis of a chronic disease and hazardous drug use were significant predictors of poor subjective sleep quality, accounting for 37.1% of the total variance of sleep quality (R²= 0.371, F(7, 1572) = 131.78, p ≤ 0.000). These data will assist in developing targeted strategies and interventions for workers to achieve better sleep quality, overall well being and a safer workplace.
The influence of local and whole-body cooling on pulmonary and muscle oxygen uptake kinetics during moderate exercise
(2020-03-04) Beckett-Brown, Nicholas
This study investigated oxygen kinetics and blood flow in response to core and muscle cooling at the onset of moderate exercise. Eight males performed two 3-min cycling bouts at moderate intensity (80% of the first ventilatory threshold) with (leg cooling; LC), and without (thermoneutral; TN) cooling of the vastus laterals (VL) muscle by 6 °C, and when core temperature was also decreased (whole-body cooling; WBC) by 1 °C. Muscle blood flow, and muscle (VO2m) oxygen uptake, and kinetics, as well as cardiovascular hemodynamics kinetics, were assessed. VO2 was higher in WBC (+1.96 mL kg -min', p = 0.023). Despite central (reduced cardiac output, heart rate pH, PO, SO2, and increased VO20 whole-body A-VO,Diff, PCO,) and local changes (decreased muscle blood flow and increased local-leg A-VO,Diff) induced by core and muscle cooling, oxygen and cardiovascular hemodynamics kinetics remained unaltered. This study demonstrated that local muscle cooling by 6 °C and core cooling by 1 °C do not influence local muscle or pulmonary oxygen kinetics during moderate exercise. Whether muscle priming, antagonist muscle activity, exercise intensity, cooling intensity or modality influenced the lower oxidative capacity of cooled muscles on kinetics remains unclear.
Understanding women athlete concussion in socio-cultural context: a media analysis of Eugenie Bouchard’s concussion
(2019-11-25) Carruthers, Andrea
The purpose of the present study was to explore the news media’s portrayal of one elite Canadian athlete, tennis player Eugenie Bouchard, and her performance decline after sustaining a concussion outside of sport. An ethnographic content analysis was used to examine news media reports of prior to, and after the concussion. An overarching theme of ‘performance decline beyond tennis’ was identified in the pre- and post-concussion North American media articles. These results show the value of studying one media incident focusing on a woman athlete, highlighting the impact of the concussion within and outside of tennis. The present study of Bouchard’s career adds to sport psychology injury literature as it demonstrated the inconceivable resiliency and mental toughness an athlete had to face during recovery and return-to-play, inconsistency due to coaching changes, an inability to recover from injuries, and a decline in rankings, all caused by confidence issues.
La perception des diplômés d’une école des sciences de l’activité physique à l’égard du développement de leurs compétences professionnelles en physiothérapie : une étude de cas
(2019-12-19) Serresse, Cindy
Le but de cette thèse est de mieux comprendre le processus de développement des sept compétences professionnelles des physiothérapeutes lors d’une première formation de base à l’école des sciences de l’activité physique (ÉSAP) de l’Université Laurentienne. La question principale est : « Quels sont les dispositifs curriculaires et pédagogiques de formation à la compé tence professionnelle que l’ÉSAP met en place lors des quatre années de formation ? » La méthode utilisée est celle d’une approche qualitative d’étude de cas. Elle a permis d’analyser les propos recueillis lors des entrevues individuelles semi-structurées auprès des neuf participants. L’analyse des données révèle deux types de dispositifs curriculaires 1) les cours théoriques, pratiques et laboratoires; 2) la structure du programme et deux types de dispositifs pédagogiques 1) les stratégies d’enseignement et 2) les stratégies d’apprentissage). Enfin, il est possible d’affirmer que les dispositifs curriculaires et pédagogiques mis en place à l’ÉSAP contribuent grandement au développement des sept compétences professionnelles essentielles à la physiothérapie.
