We will tackle the issue of relative age effect (RAE) in Canadian hockey. RAE refers to the over-representation of players born in the first quarter of the year (January-March) in elite hockey, stemming from an advantage in physical development during crucial selection periods. We break down two new studies examining the RAE's impact across different levels of play. ● First, we head to Quebec, analyzing a study of minor hockey players aged 12-17. This study reveals that RAE is present across all competition levels, but surprisingly doesn’t significantly impact young players' attitudes toward sports or physical activity. ○ However, the study uncovers a key difference in perceived competence, with players born in Q1 demonstrating a stronger physical self-concept, especially at competitive levels. ○ We'll analyze the potential reasons for this discrepancy and its impact on player development. ● Next, we shift our focus to the Canadian Hockey League (CHL), home to the nation's top junior talent. Our examination of a recent study reveals that RAE remains deeply entrenched at this elite level. ○ We uncover compelling evidence that Q1 players are more likely to outperform their Q4 counterparts in games played and power-play points. ○ This data suggests that despite efforts to address RAE, the bias towards early-born players persists as they progress through the ranks. ● This episode unpacks the possible explanations for the RAE's persistence, exploring the historical emphasis on physicality in hockey and the potential for unconscious bias among coaches and scouts. ○ We'll examine the “physical prototype” in hockey and how evolving trends in the NHL may affect the RAE. ● We’ll also address the long-term implications of the RAE, including the under-representation of late-born talent. ○ We discuss the possibility of a “reversal” effect, where late-born players catch up or even surpass their older peers in later stages of development. ○ The episode explores strategies to mitigate the RAE, such as educating stakeholders, promoting long-term athlete development models, and delaying selection processes. Join us as we shed light on the RAE's impact on Canadian hockey, and discuss strategies for a more equitable and inclusive future for the sport.
