Professional sport leagues play an important, if perhaps underappreciated,
function within sport development systems. This entry focuses on exploring the
role of professional leagues within sport development systems. Notably, the
financial resources that are associated with professional sport leagues can yield
sport development outcomes that often cannot be replicated in elite (i.e. highperformance)
sports that do not have professional sport leagues. Central to this is
the financial remuneration and associated support provided to athletes, which
contracts athletes and allows them to focus on their sport career. By contrast,
athletes in semi- or non-professional settings must grapple with greater career
duality to maintain financial and employment security, creating inherent
resourcing trade-offs that may ultimately impact high performance and the
longevity of their sport careers. Additionally, the competitive nature of
professional sport leagues results not only in greater investment in highperformance
infrastructure for athletes, but also in the surrounding workforce such as in talent attraction and retention. Investment in high-performance
technology, which continues to advance, is allowing wealthier professional sport
leagues to better optimise athlete performance and wellbeing. By contrast, national sport organisations with less professionalised elite sport environments are more likely to be characterised by greater athlete self-reliance, self-sacrifice, and volunteer labour. Finally, while professional sport leagues make evident contributions in the context of elite sport, so too can they yield sport development benefits in respect to mass participation. Although the trickle-down effect remains a contentious phenomenon, professional sport leagues retain some capacity to offer a role modelling benefit at the community sport level and pathways to careers in sport.
