Abstract: 

Introduction: To study peak oxygen uptake in child and adolescents during physical growth and development, in addition to age, sex and inheritance, biological maturity is effective factor on peak oxygen uptake and most studies to pay attention to it. The purpose of this study is Comparison of peak oxygen uptake in non athlete's adolescent girls with different maturity status.
Methodology: 39 girl’s students 13.66-14.66 years were selected by purposive sampling from population of adolescent girls in Tehran and were classified to three maturity status early, average and late by age at menarche. Body fat percent and Peak oxygen uptake were assessed by body composition analyzer and Bulk test respectively. Also variables such as chronological age, age at menarche, height, weight, body mass index, body fat percent and Peak oxygen uptake (absolute and relative) were described by central tendency and measure of variation and were compared between different maturity statuses by the help of analysis of variance. In additional multiple regression analysis was used to determine variable’s share in prediction of Peak oxygen uptake in adolescent girls.
Results: the results showed that relative peak oxygen uptake significantly was higher in late maturate than early and average maturational groups (P<0.01); but weight, body fat percent and absolute peak oxygen uptake don’t different in there maturational groups significantly. There was Significance correlation between relative peak oxygen uptake with age at menarche, BMI, body fat percent and maturity status, also between absolute peak oxygen uptake with height, weight, BMI and body fat percent (p<0.05). Body fat percent and maturity status were most importance considerable variables to predict relative peak oxygen uptake (R=0.638). Also body weight and age at menarche were most importance considerable variables to predict absolute peak oxygen uptake (R=0.763).
Conclusion: the results of this study indicated that peak oxygen uptake actually was under the influence of maturity. Although analysis of variance test and multiple regression analysis showed that to predicting absolute peak oxygen uptake, age at menarche was one of the most important factors between considerable variables after than weight.
