Mean (standard deviation (SD)) peak height velocity (PHV) of males and females in the 1993 and 2013 generations_ Height increments for the calculation of PHV were obtained for each subject of the two generations from the annual anthropometric measurements performed nationally at schools_ Any presented age is the lower margin of an annual interval in which the PHV was observed_ The t-test relates to a difference in PHV between 1993 and 2013_ NA – not applicable_
