Résumé
Abstract Aim: The aim of this study was to characterize the developmental pathway undertaken by Portuguese expert track and field athletes considering the quantity and type of structured and unstructured activities. Methods: The sample was composed of 24 experts and 35 non-expert athletes who completed a questionnaire designed to gather information about their previous experiences in sports. Results: Results reveal key factors which distinguished expert from non-expert athletes' developmental pathway were related to a greater commitment within track and field in relation to years (U = 251.000, p < 0.01) and hours (U = 212.500, p < .01), as well as with the number of years spent in unstructured activities (U = 284.500, p < .05). Furthermore, a significant association (χ2 = 27.131, p < 0.01) was found between the number of unstructured activities practiced and an expert performance attainment. Conclusions: These findings revealed that more successfully track and field athletes had an early diversified pathway with greater involvement in structured and unstructured activities. Overall, the study provides an insight into the developmental pathway of Portuguese track and field athletes.
