Cardiorespiratory fitness (CRF), as one of the most potent prognostic factors in medicine, is followed longitudinally to guide clinical management. Coronavirus disease 2019 (COVID-19) pandemic-related changes in lifestyle stand to influence CRF.
To assess the influence of the pandemic on perceived CRF in athlete patients and evaluate how perceived CRF change was related to demographics, pre-pandemic measured CRF, and current physical activity (PA).
Prospective cohort study, utilizing electronic survey.
Tertiary care sports cardiology clinical practice.
Adult athlete patients without COVID-19 with pre-pandemic measured CRF using cardiopulmonary exercise testing.
Not applicable.
Perceived change in CRF since pandemic onset; association between perceived CRF change and demographics, PA, health status, and pre-pandemic measured CRF assessed via analysis of variance (ANOVA).
Among 62 participants (male: 71%, 50.1 ± 12.1 years old), 40% (25/62) reported no change and 32% (20/62) reported an increase in perceived CRF since pandemic onset. Among the 27% (17/62) who reported a decrease in perceived CRF, in most (12/17), this was characterized as only mild. Demographics and pre-pandemic measured CRF did not differ across groups of perceived CRF change. Participants with a moderate or greater decrease in perceived CRF regarded their overall health (via Euro Quality of Life Visual Analogue Scale) as worse than other groups (ANOVA, p = .001). Although total PA was similar across groups, those who had improvement in perceived CRF reported higher levels of moderate intensity PA (ANOVA, p = .008).
The majority of participants perceived that they had maintained or improved CRF over the pandemic. Findings from this study suggest that a reduction in perceived CRF from pre-pandemic values in athletic patients in clinical practice may not result from population-wide pandemic changes in lifestyle. Worse health status and lower levels of moderate intensity PA were associated with perceived reduction in CRF over the pandemic in athlete patients.
心肺适能（CRF）作为医学中最有力的预后因素之一，一直被纵向跟踪以指导临床管理。与 2019 年冠状病毒病（COVID-19）大流行相关的生活方式变化势必会影响 CRF。
评估大流行对运动员患者感知 CRF 的影响，并评估感知 CRF 变化与人口统计学、大流行前测量的 CRF 以及当前体力活动（PA）的关系。
前瞻性队列研究，利用电子调查。
三级运动心脏病学临床实践。
无 COVID-19 的成年运动员患者，具有大流行前通过心肺运动测试测量的 CRF。
不适用。
自大流行开始以来感知到的 CRF 变化；通过方差分析（ANOVA）评估感知到的 CRF 变化与人口统计学、PA、健康状况和大流行前测量的 CRF 之间的相关性。
在 62 名参与者（男性：71%，50.1±12.1 岁）中，40%（25/62）报告没有变化，32%（20/62）报告自大流行开始以来感知到的 CRF 增加。在报告感知到的 CRF 下降的 27%（17/62）中，在大多数（12/17）中，这种下降仅为轻度。感知到的 CRF 变化组之间的人口统计学和大流行前测量的 CRF 没有差异。感知到的 CRF 有中度或更大下降的参与者认为他们的整体健康状况（通过欧洲生活质量视觉模拟量表）不如其他组（ANOVA，p=0.001）。尽管各组的总 PA 相似，但感知到的 CRF 改善的参与者报告了更高水平的中等强度 PA（ANOVA，p=0.008）。
大多数参与者认为他们在大流行期间保持或提高了 CRF。这项研究的结果表明，在临床实践中的运动员患者中，与大流行前相比，感知到的 CRF 下降可能不是由于全人群生活方式的大流行变化所致。在大流行期间，感知到的 CRF 下降与较差的健康状况和较低水平的中等强度 PA 相关。
