FC Barcelona is a multi-sport organization that adopts a talent identification approach that emphasizes the technical, psychological, and perceptual-cognitive attributes. It is unclear within this type of sporting selection model whether the relative age effect (RAE) exists. Consequently, the aim of the study was to evaluate the RAE across multiple sports and age groups at FC Barcelona. The birthdates of all players ( = 6,542) affiliated to each sport [male basketball ( = 1,013), male ( = 3,012) and female ( = 449) soccer, male futsal ( = 761), male handball ( = 999), and male indoor roller hockey ( = 308)] across all age groups from U10 to Senior were recorded. These were then categorized into quartiles from the start of the selection year (Q1 = Jan-Mar; Q2 = Apr-Jun; Q3 = Jul-Sep; Q4 = Oct-Dec) and analyzed for (a) each sport; (b) each age group, irrespective of the sport; and (c) each age group within each sport, using Chi-squared statistics and odds ratios (ORs) with 95% confidence intervals (CIs). Birthdates across the entire club revealed a RAE (Q1 = 46.1%, Q2 = 27.1%, Q3 = 17.1%, and Q4 = 9.7%, χ = 29.8, < 0.01), with OR in Q1, Q2, and Q3 representing a 4.76 (95% CIs: 1.96-11.57), 2.80 (1.12-7.03), and 1.77 (0.67-4.63) increased likelihood for selection when compared to Q4, respectively. Despite FC Barcelona's approach to talent identification and development, the RAE was still present within youth age groups (<18 years old). The current findings provide support that the RAE is more prevalent within regionally popular sports and reduces with increasing age; however, given the talent identification processes within FC Barcelona's sporting model, additional factors beyond the physical attributes, such as enhanced psychological and perceptual-cognitive attributes, in those born earlier in the selection year might further influence the RAE. Consequently, current results provide indirect evidence to suggest that sociological and psychological determinants might be a greater influence on the presence of RAE in sporting environments that prefer to consider technical and perceptual-cognitive attributes in their talent development programs.
巴塞罗那足球俱乐部是一个多项目体育组织,采用一种强调技术、心理和感知认知属性的人才识别方法。在这种体育选拔模型中,相对年龄效应(RAE)是否存在尚不清楚。因此,本研究的目的是评估巴塞罗那足球俱乐部多个体育项目和年龄组中的相对年龄效应。记录了从U10到成年组所有年龄组中每个体育项目(男子篮球(n = 1013)、男子(n = 3012)和女子(n = 449)足球、男子室内五人足球(n = 761)、男子手球(n = 999)以及男子室内轮滑曲棍球(n = 308))所有球员(n = 6542)的出生日期。然后将这些出生日期从选拔年开始分为四分位数(Q1 = 1月 - 3月;Q2 = 4月 - 6月;Q3 = 7月 - 9月;Q4 = 10月 - 12月),并针对以下情况进行分析:(a)每个体育项目;(b)每个年龄组,不考虑体育项目;以及(c)每个体育项目内的每个年龄组,使用卡方统计和95%置信区间(CIs)的优势比(ORs)。整个俱乐部的出生日期显示存在相对年龄效应(Q1 = 46.1%,Q2 = 27.1%,Q3 = 17.1%,Q4 = 9.7%,χ² = 29.8,p < 0.01),与Q4相比,Q1、Q2和Q3中的OR分别表示入选可能性增加了4.76(95% CIs:1.96 - 11.57)、2.80(1.12 - 7.03)和1.77(0.67 - 4.63)。尽管巴塞罗那足球俱乐部采用了人才识别和培养方法,但相对年龄效应在青少年年龄组(<18岁)中仍然存在。目前的研究结果支持相对年龄效应在地区流行体育项目中更为普遍且随着年龄增长而降低这一观点;然而,考虑到巴塞罗那足球俱乐部体育模式中的人才识别过程,选拔年较早出生的人除了身体属性外,诸如更强的心理和感知认知属性等其他因素可能会进一步影响相对年龄效应。因此,目前的结果提供了间接证据,表明在倾向于在其人才培养计划中考虑技术和感知认知属性的体育环境中,社会学和心理学决定因素可能对相对年龄效应的存在有更大影响。
