Kurzfassung:
Cardiopulmonary exercise testing (CPET) is an important measurement in clinical practice, and its primary outcome, maximal oxygen uptake (V˙O 2peak ), is inversely associated with morbidity and mortality. The purposes of this study are to provide CPET reference values for maximal and submaximal parameters across the adult age spectrum of a healthy European cohort, to compare V˙O 2peak values with other reference data sets, and to analyze the associations between physical activity (PA) levels and CPET parameters. Methods In this cross-sectional study, we prospectively recruited 502 participants (47% female) from 20 to 90 yr old. The subjects performed a CPET on a cycle ergometer using a ramp protocol. PA was objectively and continuously measured over 14 d using a triaxial accelerometer. Quantile curves were calculated for CPET parameters. To investigate the associations between CPET parameters and PA levels, linear regression analysis was performed. Results V˙O 2peak values observed in the group of 20–29 yr were 46.6 ± 7.9 and 39.3 ± 6.5 mL·kg −1 ⋅min −1 for males and females, respectively. On average, each age category (10-yr increments) showed a 10% lower V˙O 2peak relative to the next younger age category. V˙O 2peak values of previous studies were on average 7.5 mL·kg −1 ⋅min −1 (20%) lower for males and 6.5 mL·kg −1 ⋅min −1 (21%) lower for females. There was strong evidence supporting a positive association between the V˙O 2peak (mL·kg −1 ⋅min −1 ) and the level of habitual PA performed at vigorous PA (estimate, 0.26; P 〈 0.001]. Conclusion Maximal and submaximal CPET reference values over a large age range are novel, and differences to other studies are clinically highly relevant. Objectively measured vigorous-intensity PA showed a strong positive association with higher V˙O 2peak and other performance-related CPET parameters, supporting the implementation of higher-intensity aerobic exercise in health promotion.
