The Influence of Previous Injury History on Health and Fitness Outcomes in Junior High School Students (Master's thesis, University of Calgary, Calgary, Canada).

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.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
