    An Intervention Program Designed to Improve Balance and Power in U14 Alpine Ski-Racers
    (2018-09-20) Kashluba, Kayla Amanda; Doyle-Baker, Patricia Katherine; Clark, Marcia L.; Emery, Carolyn A.; Jordan, Matthew J.; Westin, Maria
    Purpose: To investigate if a neuromuscular training (NMT) warm-up program during preseason improved lower limb balance and maximal muscular power compared to a standard preseason program in alpine ski-racers 10-13-years-old (U14) after 8-weeks. Methods: Quasi-experimental study design. Participants included n=73 skiers from five Alberta Alpine Ski Association (AASA) ski-clubs. Ski-clubs in the intervention group (n=3) completed 2 15-min coach-delivered NMT warm-ups a week, while the standard of care (SOC) (n=2) ski-clubs completed their standard training; NMT warm-up program included balance, strength, and agility exercises. Performance outcome measures completed at baseline and post –testing included: vertical jump (VJ), star excursion balance test (SEBT) reach distances, and predicted VO2max. Results: Participants in the intervention group demonstrated significant improvements on the VJ and SEBT. Conclusions: Dynamic balance and peak leg power improved post implementation of the NMT warm-up program in U14 alpine ski-racers.

    Exploring Physicians’ Perspectives of Exercise Specialists in Primary Care Networks
    (2015-09-28) Campkin, Lisa Marie; Doyle-Baker, Patricia Katherine
    In Primary Care Networks (PCNs) family physicians refer to multidisciplinary teams that provide complimentary services for patients requiring assistance with complex issues or illness. Exercise specialists are a recent addition to these teams, and can support patients through physical activity counselling, education and the appropriate exercise prescription. By utilizing grounded theory methodology and interview techniques, the processes and context of physicians’ considerations of exercise specialists have been explored and summarized within this study. Ten physicians were purposively sampled from Calgary PCNs, and the constant comparative method was applied to code the transcripts and construct analytic categories to saturation. The core category states that although physicians are receptive to a professional who promotes physical activity and wellness to their patients, exercise specialists are currently “hidden” from PCN family physicians in Calgary. This core category is supported by three subcategories: Exercise Specialist Factors, Access, and Relationships.

    Immune Response in Young Men to the 2014/15 Seasonal Influenza Vaccine
    (2016-02-04) Stewart, Andrew; Doyle-Baker, Patricia Katherine; Reimer, Raylene; Vanderkooi, Otto
    Currently there is limited research on the impact of adiposity and physical activity on influenza vaccination. The purpose of this pilot study was to investigate the role of adiposity and physical activity in the immune response of males aged 18-35 to the 2014/2015 seasonal trivalent influenza vaccine. Blood was drawn pre and four weeks post vaccination. Serum samples were analyzed for changes in antibody titers, serum leptin, soluble leptin receptors (sLEPR) and C-reactive protein (CRP). No differences in median percent body fat, leptin, sLEPR or CRP were associated with seroconversion rates. Participants with higher physical activity scores had lower seroconversion rates. Differences were found for the A/Texas strain (p<0.01) with a similar trend observed for the other influenza strains. Further work needs to be done in this area to confirm this trend.

    Investigating 24-Hour Movement Behaviours of Children and Youth Attending Summer Camps
    (2018-09-19) Grewal, Eshleen Kaur; Doyle-Baker, Patricia Katherine; McDonough, Meghan H.; Copeland, Jennifer L.; Sheehan, Dwayne Patrick
    The KiSS UC study (n=224) measured all four movement behaviours from the Canadian 24-Hour Movement Guidelines: light physical activity (LPA), moderate-to-vigorous physical activity (MVPA), sleep, and sedentary behaviour (SB). The study objectives were to determine the: 1) proportion of participants meeting those guidelines, 2) factors associated with meeting the guidelines (sex, age, camp type, ethnicity, number of other children in the household, parent education), and 3) out-of-camp activities engaged in. Garmin vivofits measured LPA and sleep; Garmin heart rate monitors and Actihearts measured MVPA; SB and out-of-camp activities were assessed using questionnaires (CAPL, CPAQ, respectively). A large proportion of participants met the LPA (88%), MVPA (100%), sleep (65%), and SB (78%) guidelines. Age, parent education, sex, and number of other children in the household were significant predictors for sleep and SB. In summary, summer camps may be a setting where each of the Canadian 24-Hour Movement Guidelines can be met.

    Neighbourhood Built Characteristics and their Associations with Health-related Fitness in Adults
    (2024-07-24) Frehlich, Levi Colt; McCormack, Gavin Robert; McCormack, Gavin Robert; Chowdhury, Tanvir Turin; Doyle-Baker, Patricia Katherine; Salvo, Deborah; Dogra, Shilpa
    Health-related fitness is an important marker of overall health, linked to lower morbidity and mortality. Consistently, evidence associates the neighbourhood built environment with physical activity and with health outcomes. However, sparse evidence links the neighbourhood built environment and health-related fitness. Existing studies typically focussed on cardiorespiratory or morphological fitness, yet health-related fitness is multidimensional. It remains unclear whether neighbourhood built environments that support physical activity also promote or enhance health-related fitness. Evidence suggests there are sex differences in associations between the neighbourhood built environment and physical activity. Therefore, this thesis elucidates the associations between the neighbourhood built environment and components of health-related fitness among urban-dwelling adults stratified on sex. Our systematic review found the neighbourhood built environment was associated with health-related fitness in adults and that in some cases, these associations were independent of physical activity. A secondary analysis of national data found neighbourhood walkability was positively associated with cardiorespiratory fitness but negatively associated with muscular strength, while controlling for accelerometer-measured physical activity. This was followed by a secondary analysis of provincial data associated neighbourhood built characteristics (walkability and greenness) which included muscular strength and body composition, independent of self-reported physical activity and sedentary behaviour. This study found that neighbourhood walkability may support cardiorespiratory and morphological fitness, whereas neighbourhood greenness may positively impact muscular fitness. Relationships between the neighbourhood built environment and health-related fitness were similar for males and females. In summary, neighbourhood built environments that support physical activity might also promote health-related fitness.

    The Influence of Previous Injury History on Health and Fitness Outcomes in Junior High School Students
    (2016-01-29) van den Berg, Carla; Doyle-Baker, Patricia Katherine; Emery, Carolyn; Nettel-Aguirre, Alberto; Richmond, Sarah
    Objective: To assess the influence of previous sport and recreational injury on body composition, cardiorespiratory fitness, musculoskeletal strength, and dynamic balance in junior high school students (ages 11-16). Methods: Cross-sectional study design. Participants included 1,039 students from six junior high schools in Calgary, Alberta, Canada. Demographics, injury history, and sport participation over the previous 12 months were collected using a questionnaire. Outcome measures included body mass index (BMI), waist circumference, predicted VO2max, vertical jump, eyes closed dynamic balance, and star excursion balance test reach distances. Results: Previously injured participants had significantly higher BMI and left foot balance times compared to uninjured participants. Exploratory analysis results suggest that those who sustained two injuries had a significantly increased BMI and waist circumference compared to those who sustained no injuries. Conclusions: Participants with a history of injury demonstrated more unhealthy body composition, but better left foot dynamic balance compared to uninjured participants.
