Physical efficiency tests in Indian urban adolescent boys and girls.

Simple anthropometric measurements and physical efficiency tests were performed on adolescent Indian urban boys between 10-14 years and girls between 11-14 years of age. The similar height and weight of the subjects of both sexes were observed and was suggestive of higher growth rate in girls than the boys during only the initial phase of adolescent growth spurt. The vital capacity (total, ml/cm of height, l/m2 of surface area), Peak Expiratory Flow Rate (total, l/cm of height, l/kg of weight, l/m2 of surface area, l/year of age) and grip strength were observed to be insignificantly different between the sexes.
