There’s often a temptation to treat young athletes, especially those training in sport academies, as though they’re mini adults. This includes holding expectations that they’ll appreciate the risks of their sport and behave in ways to protect their own health. This is completely unrealistic. The processes of growth and maturation, which young athletes experience at different times and rates, affect psychological and social development alongside recognized physical changes. This means that younger, less mature athletes can struggle to grasp the consequences of their actions and are more likely to try risky maneuvers or ignore safety rules. Adolescent athletes in particular are vulnerable to social pressures and evidence suggests that they’re prone to over-estimating their own abilities, both of which can lead to increased injury risk. This chapter outlines the psychological factors that are unique to this population, drawing examples from traditional team sports as well as adventure sports such as snowboarding. It describes age-appropriate strategies for limiting risk exposure for young athletes while simultaneously encouraging them to develop risk assessment skills and addresses the psychological support needs of young athletes during injury rehabilitation.
