Criterion validity of the Ekblom-Bak and the Åstrand submaximal test in an elderly population

Purpose The aim of this study was to validate the submaximal Ekblom-Bak test (EB-test) and the Åstrand test (Å-test) for an elderly population. Methods Participants ( n = 104), aged 65–75 years, completed a submaximal aerobic test on a cycle ergometer followed by an individually adjusted indirect calorimetry VO 2 max test on a treadmill. The HR from the submaximal test was used to estimate VO 2 max using both the EB-test and Å-test equations....
