Therefore, promoting the health and improving the performance of employees require examining and paying attention to their aerobic capacity. The primary purpose of the current study was to determine the aerobic capacity and to analysis individual factors associated with VO_2max among university students.</span></span></span></span><br> <span style="font-size:12pt"><span style="line-height:16.0pt"><span new="" roman="" style="font-family:" times=""><b><i><span style="font-size:9.0pt">Materials & Methods</span></i></b><b><span style="font-size:9.0pt">:</span></b><span style="font-size:9.0pt"> One hundred and thirty male and female students with a mean age of 21.6 &plusmn; 0.4 years, voluntarily participated in the present study. Aerobic capacity was determined using ergometer and the Astrand protocol. Demographic information and body mass index (BMI) of participants were also collected. Data were analyzed<i> </i>by using single and multiple-regression<i> </i>techniques.</span></span></span></span><br> <span style="font-size:12pt"><span style="line-height:16.0pt"><span new="" roman="" style="font-family:" times=""><b><i><span style="font-size:9.0pt">Results</span></i></b><b><span style="font-size:9.0pt">:</span></b><span style="font-size:9.0pt"> Mean maximum aerobic capacity was 2.18 &plusmn; 0.41 L/min. The maximum aerobic capacity was associated with weight, BMI and heart rate. The results of regression analysis indicated that BMI and heart rate could significantly predict the VO_2max of the students. The best VO_2max prediction equation has been developed based on regression analysis. </span></span></span></span><br> <span style="font-size:12pt"><span style="line-height:16.0pt"><span new="" roman="" style="font-family:" times=""><b><i><span style="font-size:9.0pt">Conclusion</span></i></b><b><span style="font-size:9.0pt">: </span></b><span style="font-size:9.0pt">The mean of students&rsquo; VO2max is lower than the counterpart population in the same society. The lack of regular exercise and a subsequent increase in BMI may lead to a significant decrease in VO2max. The significant relationship between HR, BMI and VO2max could be used to predict VO2max in young people.</span></span></span></span> Aerobic capacity, Astrand protocol, BMI, Ergometer bicycle 167 173 http://hsm.umsu.ac.ir/browse.php?a_code=A-10-45-3&slc_lang=en&sid=1 Bahareh Kermanjani 10031947532846001634 1111-1111-1111-1111 No M.Sc.
