“…In soccer, for example, significant differences have been found between early and late maturing players in variables such as muscle power, speed, body mass, height, body fat, flexibility, lower limb strength, and cardiorespiratory capacity (Gouvea et al, 2016). As a result, it is usually the early-maturing players who have greater opportunities to access specialized training and highperformance processes, while the late-maturing players are often excluded from these development opportunities (Albaladejo-Saura et al, 2022;Cobley, 2017). In relation to the latter, recent research found that late-maturing players accounted for less than 5% of the U15 and U17 cohorts in an English soccer academy (Johnson et al, 2017).…”
