Middle Adolescence (Stages 3 and 4): acceleration of weight
and growth as well as above secondary sex characteristics. Pubic hair
first, then axillary, then facial hair.
- Female: menarche (average age 12
years) - can occur in Stages 1 and 2; usually 3 and 4 factors affecting:
nutrition, genetic - age of mother’s menarche.
- Male: gynecomastia also appears
during middle adolescence: up to 70% of normal males.
Should Tanner 1 boys be allowed to play football with Tanner 5s?
Controversial. Dr Landry of Madison Wisconsin says that there is no
problem. However some literature states that adolescents that have gone
through puberty recently are at higher risk of injury. (Clinical Journal of
Sport Medicine 1995;5:167-70) Also study of strength, flexibility and
maturity correlate better with Tanner staging than with chronological age. (AJDC
1989;143:560-3)
All agree that we worry about these mismatches in sports.
