To develop standards for cardiorespiratory fitness by establishing reference values derived from cardiopulmonary exercise testing (CPX) in the United States.
Eight laboratories in the US experienced in CPX administration with established quality control procedures contributed data from January 1, 2014, through February 1, 2015, from 7783 maximal (respiratory exchange ratio, ≥ 1.0) treadmill tests from men and women (aged 20-79 years) without cardiovascular disease (CVD) to the Fitness Registry and the Importance of Exercise: A National Data Base (FRIEND). Percentiles of maximal oxygen consumption (VO 2max) for men and women were determined for each decade from 20 years of age through 79 years of age. Comparisons of VO 2max were made to reference data established with CPX data from Norway and to US reference data established without CPX measurements.
There were significant differences between sex and age groups for VO 2max. In FRIEND, the 50th percentile VO 2max of men and women aged 20 to 29 years decreased from 48.0 and 37.6 mLO2 · kg(-1) · min(-1) to 24.4 and 18.3 mLO2 · kg(-1) · min(-1) for ages 70 to 79 years, respectively. The rate of decline in this cohort during a 5-decade period was approximately 10% per decade.
These are the first cardiorespiratory fitness reference data using measures obtained from CPX in the United States. FRIEND can be used to provide a more accurate interpretation of measured VO 2max from maximal exercise tests for the US population compared with previous standards on the basis of workload-derived estimations.
通过建立源自美国心肺运动试验(CPX)的参考值来制定心肺适能标准。
美国8个具备CPX管理经验且有既定质量控制程序的实验室,提供了2014年1月1日至2015年2月1日期间,7783例无心血管疾病(CVD)的男性和女性(年龄20 - 79岁)进行的最大(呼吸交换率≥1.0)跑步机测试数据,这些数据被纳入健身注册与运动重要性:国家数据库(FRIEND)。确定了20岁至79岁每个十年男性和女性的最大摄氧量(VO₂max)百分位数。将VO₂max与挪威CPX数据建立的参考数据以及未通过CPX测量建立的美国参考数据进行比较。
VO₂max在性别和年龄组之间存在显著差异。在FRIEND中,20至29岁男性和女性的VO₂max第50百分位数分别从48.0和37.6 mLO₂·kg⁻¹·min⁻¹下降至70至79岁时的24.4和18.3 mLO₂·kg⁻¹·min⁻¹。该队列在5个十年期间的下降率约为每十年10%。
这些是美国首批使用CPX测量值的心肺适能参考数据。与基于工作量估算的先前标准相比,FRIEND可用于更准确地解释美国人群最大运动测试中测得的VO₂max。
