More specifically, this investigation highlighted i) mortality outcome differences of athletes between and within professional sport(s), ii) potential statistical artifacts that may be empowering biases of risk of certain lifespan predictors and iii) the challenges of contextualizing historical data to answer questions with relevance in the present where socio-contextual factors may be different. Methods: Data on player lifespan and biological and occupational variables were collected from publically available sources. A majority of the data were collected from wikipedia.org and sports-reference.com, which is a recognized sports archive of aggregated athlete records, and were cross-verified through rigorous web-based and sport encyclopedia archival searches. Several methodological approaches were used across seven studies, including descriptive and Kaplan-Meier and Cox regression survival analyses. Results: The key findings of this dissertation suggest that elite athletes generally have favourable lifespan outcomes, although numerous characteristics need to be taken into consideration, such as occupational (e.g., required energy system needed for participation) and biological (e.g., height) differences. As well, the leading causes of death in players from the four major sports in North America are similar to the leading causes of death in the age- and sex-matched controls from the Canadian and United States general population. Conclusions: Statistical limitations and biased reporting may skew public perception of the relationship between participation in high performance sport and lifespan. As such, there is inherent value in scientists critically examining the health outcomes of athletes and to make these data known to a broader audience, particularly as preconceived notions of health risks from sport participation vocalized through media often distort reality and can adversely affect sport participation rates. In summary, a comprehensive understanding of the implications of involvement in elite sport informs our broader understanding of general athlete health and helps to form evidence-based models of athlete development and care.enAuthor owns copyright, except where explicitly noted.
