Abstract

Background and Objectives: Accurate and rapid measurement of cardiorespiratory system performance by estimation methods regardless of basic physiological fitness level, geographical environment, culture and nutrition is of paramount importance. The purpose of this study was to design linear regression equations to estimate the Aerobic capacity of healthy adolescent boys without the use of sport tests and Validation of this equations. Methods: In the present semi-experimental study, 156 healthy adolescent boys aged 13 to 17 years with a mean body mass index of 21. 43 ± 4. 5 Kg / m2 were selected by purposive sampling method. To design the non-sport equation for estimating maximum oxygen consumption (VO2peak), a multiple regression linear model and Pearson correlation were used to validate the equations. Results: Significant correlations were observed between the measured VO2peak and the anthropometric and physiological variables (R=0. 122-0. 799, P<0. 001). Also, a valid non-exercise linear equation for boys' VO2peak prediction was designed with variables such as age, BMI and resting heart rate (SEE = 3. 59 mL/kg/min, R2 = 0. 712, P<0. 001). The estimated VO2peak from equations had a significant correlation with the obtained criterion value. (R = 0. 707 – 0. 730, P<0. 01). Conclusion: According to the results of the present study, it is possible to use Aerobic capacity estimation equations, is a simple, accurate, safe tool in assessing the baseline cardiorespiratory fitness (VO2peak). The use of non-Exercise equations in the planning of exercise in large populations of adolescent boys and even as a daily clinical practice in the elderly and heart patients with the goals of promoting health, cardiovascular health, preventive actions is very important.
