This work was conducted with the support of 19-20 years old students during physical education classes across the 1st Semester of AY 2017/2018 at the Bucharest University of Economic Study. The study case starts with the premise that all subjects were under/medium level trained and it focuses on a cross-screening survey which includes body mass index, oxygen consumption, heart rate activity, oximetry, spirometry and caloric consumption rate. The participation of subjects was voluntary and for this they signed a written agreement which allows the results to be published. The surveillance process was made using approved devices and a previously tested methodology. The final results revealed that there is no correlation between VO2, BMI and FVC for the subjects of the group.
