Abstract

Purpose: To study whether peak oxygen uptake (VO2 (peak)), attained in traditional cardiopulmonary exercise testing (CPET) in adolescents with cystic fibrosis (CF), could be verified by a supramaximal exercise test.

Methods: Sixteen adolescents with CF (forced expiratory volume in 1 second as % of predicted [range, 45%-117%]) volunteered and successively performed CPET and a supramaximal test (Steep Ramp Test [SRT] protocol).

Results: Cardiopulmonary exercise testing and the SRT resulted in comparable cardiorespiratory peak values. We found no significant difference in oxygen uptake (VO2 peak/kg) between CPET and the SRT (38.9 +/- 7.4 and 38.8 +/- 8.5 mL min(-1) kg(-1), respectively; P =.81). We found no systemic bias for CPET and SRT measurements of VO2 peak/kg and no differences between CPET and SRT VO2 peak values within and between the maximal and non-maximal effort groups (P >.4). Conclusion: The VO2 peak measured in CPET seems to reflect the true VO2 peak in adolescents with CF. (Pediatr Phys Ther 2011; 23: 15-21)
