It was proved that VO2max and VO2max/kg values could be calculated according to the maximal performance (Wmax and Wmax/kg attained on bicycle ergometer. Regular aerobic endurance exercise could reduce biological age of active individuals by 10 to 20 years with a correspondingly decreased likelihood of becoming dependent when a senior and an expressive improvement in the quality of the final years of life (Shephard, 1994).
VO2max and VO2max/kg values represent important health quality biomarkers. They also offer feedback information, positive and/or negative, about the effectiveness of physical aktivity influencing its development.
Thus, aerobic fitness level has been strongly and positively associated with reduced morbidity, prevalence and mortality rates of so called civilization diseases, good quality of life, performance level, and functional ability. Thus, if no 02-CO2 analyzer during ergometry examination is available, calculated VO2max and VO2max/kg values can be used for evaluation of cardio-respiratory capacity.
