Three out of four linear measurements i.e. stature, upper extremity length, lower extremity length show the peak velocities in the age group of 12+ years. Upper arm circumference shows higher magnitude of growth in the age groups 15-16 and 16-17, whereas 16-17 years are grow at least increment for chest circumference. Increments with regards to head circumference are evenly distributed throughout all the age groups. The composite measurement of weight shows a study and uniform progression through all the age groups with 16-17 years regarding the maximum increment.
