Adolescents undergo rapid physical growth, with testosterone levels in boys reaching peak genetic influence (Grotzinger et al., 2018). Motor competence begins shaping self-worth and identity, while physical education enhances foundational movement skills and confidence (Lorås, 2020; Timler, McIntyre, Rose, & Hands, 2019).

Physical development continues with improved coordination and strength. Testosterone heritability peaks in girls, influencing mood and body image (Grotzinger et al., 2018). Low self-perceptions and friendships can inhibit identity, especially for those with low motor competence (Timler, McIntyre, Rose, & Hands, 2019).

Pubertal growth stabilises as genetic influence on hormones declines and environmental factors increase (Grotzinger et al., 2018). Motor competence continues shaping identity and lifelong activity habits, with physical education playing a key role in self-confidence and health (Lorås, 2020; (Timler, McIntyre, Rose, & Hands, 2019)).
