Fig. 2From: Beta-Adrenergic Receptor Blockade Effects on Cardio-Pulmonary Exercise Testing in Healthy Young Adults: A Randomized, Placebo-Controlled TrialIndividual CPET derived HR/VO2 slopes measured in healthy subjects under placebo, 2.5 mg bisoprolol or 5.0 mg of bisoprolol. Mean values are represented by large horizontal bars and standard deviation by vertical bars in each condition. B1 adrenoreceptors blockade negatively affected the HR/VO2 slopeBack to article page
