Longitudinal monitoring of 1925 children (990 boys, 935 girls), aged 6-15 years, at 20 elementary schools in four regions of the Czech Republic, which has been conducted at the same time. Data of repeatedly examined probands of a wide age range were acquired in a short time period.
With the help of a linear regression model with mixed effect, the growth velocity curves of 12 somatic traits have been obtained. The timing, intensity and duration of separate growth spurts have been observed, as well as the mutual location of both points of growth velocity, local maxima and minima, and points of the maximal acceleration and deceleration.
The results demonstrate that the velocity of characters with variable growth dynamics.
