 This study examined the relationship between cardiovascular parameters measured during submaximal exercise tests and maximal oxygen consumption, VO2max. The results showed that maximal oxygen consumption can be accurately predicted from submaximal exercise tests performed at either the anaerobic threshold, AT, or the respiratory compensation point, a CP. Furthermore, the authors found that body mass and body fat had the greatest impact on the somatic equation, while variables related to aerobic capacity such as VO2max at AT and RCP were more influential in the other two equations. These findings suggest that submaximal exercise tests may provide a reliable estimate of VO2max, which could be useful for both sport and clinical applications.
