This process continues throughout the middle years with a somewhat slower pace. As the child enters puberty, rapid development of physical and sexual characteristics becomes more apparent, accompanied by important psychosocial development. The onset and rate of progression of pubertal events vary considerably among adolescents; however, the changes occur in a predetermined sequence.1,2 The adolescent may perceive sport experiences quite differently based on the influences of several variables: the differences in physical and psychosocial development, states of adolescent development (early: 10–13 years of age; middle: 14–16 years of age; and late: 16–20 years of age), as well as those who mature early or late.3–8 Also, gender differences become more apparent and significant for sport participation during adolescence (Figure 2-1). Clinically, it is important to assess an adolescent's sexual maturity rating (SMR) or Tanner staging (Figures 2-2, 2-3, and 2-4), because chronologic age does not necessarily correlate well with many physiologic and somatic changes. Skeletal maturity is best assessed by measurement of bone age.
