  1. Measured VO2max = maximal oxygen uptake, RER = respiratory exchange ratio, HR = heart rate, BPM = beats per minute, *percent of age predicted maximal HR according to Fox-Haskell formula (220 – age), **according to Tanakas formula (208–0.7 · age), ***according to Nes’ formula (211–0.64 · age), BP = blood pressure, RPE = ratings of perceived exertion.
