To provide updated reference standards for cardiorespiratory fitness (CRF) for the United States derived from cardiopulmonary exercise (CPX) testing when using a treadmill or cycle ergometer.
Thirty-four laboratories in the United States contributed data to the Fitness Registry and the Importance of Exercise National Database. Analysis included 22,379 tests (16,278 treadmill and 6101 cycle ergometer) conducted between January 1, 1968, through March 31, 2021, from apparently healthy adults (aged 20 to 89 years). Percentiles of peak oxygen consumption for men and women were determined for each decade from 20 through 89 years of age for treadmill and cycle exercise modes, as well as when defining maximal effort as respiratory exchange ratio (RER) greater than or equal to 1.0 or RER greater than or equal to 1.1.
For both men and women, the 50 percentile scores for each exercise mode decreased with age and were higher in men across all age groups and higher for treadmill compared with cycle CPX. The average rate of decline per decade over a 6-decade period was 13.5%, 4.0 mLO·kg·min for treadmill CPX and 16.4%, 4.3 mLO·kg·min for cycle CPX. Observationally, the mean peak oxygen consumption was similar whether using an RER criterion of greater than or equal to 1.0 or greater than or equal to 1.1 across the different test modes, ages, and for both sexes. The updated reference standards for treadmill CPX were 1.5 - 4.6 mLO·kg·min lower compared with the previous 2015 standards whereas the updated cycling standards were generally comparable to the original 2017 standards.
These updated cardiorespiratory fitness reference standards improve the representativeness of the US population compared with the original standards.
提供更新的美国心肺适能（CRF）参考标准，这些标准源于使用跑步机或固定自行车进行心肺运动（CPX）测试。
美国的 34 个实验室向健身登记处和运动对健康重要性国家数据库贡献了数据。分析包括 1968 年 1 月 1 日至 2021 年 3 月 31 日期间进行的 22379 次测试（16278 次跑步机和 6101 次固定自行车），来自健康成年人（年龄 20 至 89 岁）。为每个十年确定了男性和女性在跑步机和固定自行车运动模式下的峰值耗氧量的百分位数，以及将最大努力定义为呼吸交换比（RER）大于或等于 1.0 或 RER 大于或等于 1.1 时的百分位数。
对于男性和女性，每个运动模式的 50 百分位分数随年龄下降，在所有年龄组中男性分数较高，跑步机 CPX 比固定自行车 CPX 分数高。在 6 个十年期间，每个十年的平均下降率为 13.5%，跑步机 CPX 为 4.0 mLO·kg·min，固定自行车 CPX 为 16.4%，4.3 mLO·kg·min。观察到，无论使用 RER 标准大于或等于 1.0 还是大于或等于 1.1，不同测试模式、年龄和性别之间的平均峰值耗氧量都相似。与之前的 2015 标准相比，更新的跑步机 CPX 参考标准低 1.5-4.6 mLO·kg·min，而更新的自行车标准通常与原始的 2017 标准相当。
与原始标准相比，这些更新的心肺适能参考标准提高了美国人口的代表性。
