The purpose of this study was to determine the reliability of allometric equation in measuring the vo2max of 12 to 16 years old girl students. 114 girl students (aged 14 +/-2 years, weight 50.64 +/- 9.7 kg, height 156.1 +/- 7.11 cm) took part in the study and their V02max were calculated by Brucc protocol and also through allometric equation .The allometric equation in this research is vo2max = 1.94 M 75 . Then, the statistical methods of pierssonʹs correlation coefficient were used to asses the reliability. The analysis of the data showed that allometric equation enjoys high reliability in determining V02max, r= .75 (P = 0.01), when vo2max was absolute (1/ min).
The reliability in alls group are: In first group, students 12 yr: i= .80, P = .01 in second group, studentds 13 yr: r=.698, P= 01, in third group, students 14 yr: r=.775, P = .01, in fourth group, students 15 yr: r= .591, P = .01, in fifth group, students 16 yr: r= .673, P = .01. But when V02max is relative vo2max (ml /kg /min), the reliability between V02max by allometric equation and V02max by Brucc protocol is r= - .362, P = .01. Therefore, according to the results obtained, allometric equation can be used for determine the absolute V02max of girl students in the conditions when physical education laboratory is not available.
