To study whether peak oxygen uptake ((Equation is included in full-text article VO₂ peak), attained in traditional cardiopulmonary exercise testing (CPET) in adolescents with cystic fibrosis (CF), could be verified by a supramaximal exercise test.
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).
Cardiopulmonary exercise testing and the SRT resulted in comparable cardiorespiratory peak values. We found no significant difference in oxygen uptake ((Equation is included in full-text article VO₂ peak/kg) between CPET and the SRT (38.9 ± 7.4 and 38.8 ± 8.5 mL min kg, respectively; P = .81). We found no systemic bias for CPET and SRT measurements of (Equation is included in full-text article VO₂ peak/kg and no differences between CPET and SRT (Equation is included in full-text article VO₂ peak values within and between the maximal and non-maximal effort groups (P > .4).
The (Equation is included in full-text article VO₂ peak measured in CPET seems to reflect the true (Equation is included in full-text article.)O2 peak in adolescents with CF.
研究在囊性纤维化（CF）青少年患者的传统心肺运动试验（CPET）中达到的峰值摄氧量（全文包含公式VO₂ 峰值）是否能通过次极量运动试验得到验证。
16名CF青少年患者（1秒用力呼气量占预测值的百分比[范围，45%-117%]）自愿参加，先后进行CPET和次极量试验（陡坡试验[SRT]方案）。
心肺运动试验和SRT产生了相当的心肺峰值。我们发现CPET和SRT之间的摄氧量（全文包含公式VO₂ 峰值/千克）无显著差异（分别为38.9±7.4和38.8±8.5毫升·分钟·千克；P = 0.81）。我们发现CPET和SRT对（全文包含公式VO₂ 峰值/千克）的测量没有系统偏差，并且在最大努力组和非最大努力组内及组间，CPET和SRT的（全文包含公式VO₂ 峰值）值没有差异（P > 0.4）。
CPET中测量的（全文包含公式VO₂ 峰值）似乎反映了CF青少年患者的真实（全文包含公式）O2 峰值。
