minating peak of PS at the age of 12.8 years.
The average growth velocity of subischial
length reaches values that are equal to those
of sitting height in all phases of growth.
Subischial length – Girls
(Table 4b, Figure 4b)
In girls the peak of MGS was reached at
the average age of 7.6 years (T3). The average
age of the beginning of pubertal acceleration
of subischial length (T6 = 8.7 years)
coincided with the start of the PS of body
height. However, girls reached maximal

also the point of its maximal deceleration
at the age of 10.5 years, i.e. 0.7 year sooner
than in body height parameters.
Intersexual difference
In agreement with other length parameters
the MGS of subischial length starts
sooner in girls and their advance exhibits
an intersexual age difference ranging in the
interval from 0.6 to 1.0 year. The same trend
is observed also in the PS. On average the
start of PS (T6) in girls begins 1.5 years sooner
than in boys and its peak (T8) is reached
2 years earlier. Although the values of the
