Variations in the constituent year effect in Junior World Championships in alpine skiing: A window into relative development effects?

Abstract

While research on the effects of 'birth month' is usually referred to as relative age effects, the study of the effects of 'birth year' is described as the constituent year effect (CYE). In the present study we examined the impact of the CYE on participation in the Junior World Championship in alpine skiing. Based on previous research, we expected to find increasing numbers of participants the older the age-group, and that the CYE would be stronger in the speed events compared to the technical ones. The sample in the present study consisted of 1188 male skiers and 859 female skiers within the age range of 17 to 21 years at the time of competition. The results show that the number of male participants increased with increasing age, which can be described as a CYE. For female skiers, a CYE was found, but it dissipated two years earlier than for male skiers. The CYE varied with event and was more pronounced the higher the speed of the event. The findings thus suggest that a constituent year effect exists among skiers participating in the FIS Junior World Ski Championship in the alpine skiing championships, and that the effect varies with gender and event, rather unrelated to age. Thus, it seems that the effect may not be a relative age effect, but instead a relative development effect.

The relative age effect shifts students’ choice of educational track even within a school system promoting equal opportunities

“…As a proxy, however, the RAE is as good as any, since on average, every anthropometric and physiological variable during adolescence is almost linearly associated with age ( Júlíusson et al, 2009 ), meaning that relative age is a good indicator of relative development. It has even been argued that the RAE should instead be labelled the “relative development effect” ( Bjerke et al, 2020 ). Of course, large differences exist between individuals, as do large systematic differences between groups of individuals, as our results show.…”

“…From the perspective of specific constraints, fear of taking the cable car, enthusiasm for other leisure and entertainment activities and partners' lack of interest in skiing are the most significant factors hindering participation. From the perspective of categories of constraints, personal internal constraints are the most important, followed by interpersonal constraints, while structural constraints have no significant impact [18]. Currently, most winter sports venues are concentrated in professional profit-making venues.…”

“…Početné studie můžeme najít ale i v některých individuálních sportech, např. v tenise (Moreira, Lopes, Faria, & Albuquerque, 2017;Ulbricht, Fernandez-Fernandez, Mendez-Villanueva, & Ferrauti, 2015;Wendling & Mills, 2018) nebo lyžování (Bjerke, Lorås, Vorland, & Pedersen, 2020;Müller, Gonaus, Perner, Müller, & Raschner, 2017;Steidl-Müller, Hildebrandt, Raschner, & Müller, 2019).…”
