EVALUATION AND COMPARISON OF VO2MAX ASSESSMENT MODELS IN HIGH SCHOOL STUDENTS

The purpose of this study was to evaluation and comparison of VO2max assessment models in students. Thirty students from high schools of Ardabil city were selected randomly and served as subjects in this study (age: 15.73+-0.69 year, height: 169.46+-8.1 cm, weight: 61.70+-9.32 kg). Subjects were divided into two groups. In one group Rockport test was used to estimate their VO2 max and in other group Balk test was used for the same purpose. Also, the VO2max of both groups were examined by a standard treadmill test and the results were compared with the results of field tests. The one way of ANOVA and Tukey's post-hoc tests were used for data analysis (p>0/05). The results showed that there were significant differences between the results of the field tests and standard treadmill test (Bruce: 40.93+-5.83 vs. Rockport: 58.71+-2.73 and Balke: 52.09+- 6.18). As a result of these findings it was concluded that the regression equations used in this study used is not suitable for 15-17 (yr) boys and does not estimate their aerobic power correctly.
