Li enpòtan pou konprann devlopman fizik ak devlopman fizyolojik nan ti fi yo ak ti gason yo nan lòd yo kalifye atant ak planifye yon orè fòmasyon apwopriye pou yo. Tou de sèks gen yon to kwasans (wotè) nan apeprè 4-8cm chak ane pandan pre-pubertal ane (6-12 yrs fin vye granmoun). Nan pwen nan kwasans gen yon ogmantasyon rapid nan kwasans lan nan bra yo, janm yo ak longè kò jeneral. Anjeneral sa rive alantou laj 11yrs pou ti fi ak 12-13 yrs pou ti gason yo. Ti fi yo fè eksperyans kwasans kwasans rapid sa a anvan ti gason, men nan yon pi piti limit jeneral. Pandan peryòd sa a to kwasans lan apeprè 8-15cm / ane. Nan pifò ka sa a kwense kwasans dire 1-2 yrs. Ant laj 16-18yrs kwasans lan jeneralman kòmanse sispann.

It is important to understand pre-pubertal and pubertal physiological development of girls and boys in order to gauge expectations and plan an appropriate training schedule for them. Both sexes have a growth rate (height) of approximately 4-8cm per year during pre-pubertal years (6-12 yrs old). At the point of puberty there is a rapid increase in the growth of the arms, legs and overall body length. Generally this occurs around the age of 11yrs for girls and 12-13 yrs for boys. Girls experience this rapid growth period before boys but to a lesser extent overall. During this period the growth rate is approximately 8-15cm/yr. In most cases this growth spurt lasts 1-2 yrs. Between the ages of 16-18yrs the growth generally begins to stop.
