The one-minute sit-to-stand test (1STST) is an easy-to-administer, space and time-saving test for determining functional exercise capacity in cardiac disease. This study aimed to investigate the 1STST -test-retest reliability and convergent validity and compare its physiological responses to the six-minute walk test (6MWT) in patients with Atrial fibrillation (AF).
Forty-five patients with AF were included in this study. Functional exercise capacity was evaluated using the 1STST and 6MWT. For assessing test-retest reliability, the intraclass correlation coefficient and Bland-Altman plots were utilised. Convergent validity was determined by correlation analysis 1 STST and 6MWT, age, European Heart Rhythm Association score, ejection fraction, and quality of life. The cut-off point of 1STST was defined using ROC analysis.
With an intraclass correlation coefficient value of 0.975 [95 % confidence interval (CI) 0.954-0.986], the 1STST demonstrated excellent-test-retest reliability. Physiological responses after tests were similar in the 1STST and 6MWT (p > 0.05). The number of 1STST repetitions was strongly associated with 6MWT distance (r = 0.809; p < 0.001). A cut-off value of ≤13 repetitions in the number of 1STST repetitions was defined as functional impairment related to an increased risk of clinical events [sensitivity: 100 %, specificity: 84.6 %; AUC:0.94; 95 % CI 0.82 to 0.98; p < 0.001].
The 1STST is a reliable and valid assessment tool that produced comparable hemodynamic responses to the 6MWT in patients with AF. Considering its feasibility and time efficiency, healthcare professionals can use the 1STST rather than the 6MWT test to measure functional exercise status in a constrained environment for this patient group.
一分钟坐立试验（1STST）是一种易于实施、节省空间和时间的测试，用于确定心脏病患者的功能运动能力。本研究旨在调查1STST的重测信度和收敛效度，并比较其在心房颤动（AF）患者中与六分钟步行试验（6MWT）的生理反应。
本研究纳入了45例AF患者。使用1STST和6MWT评估功能运动能力。为评估重测信度，采用组内相关系数和Bland-Altman图。通过对1STST和6MWT、年龄、欧洲心律协会评分、射血分数和生活质量进行相关分析来确定收敛效度。使用ROC分析定义1STST的截断点。
1STST的组内相关系数值为0.975[95%置信区间（CI）0.954 - 0.986]，显示出极好的重测信度。1STST和6MWT测试后的生理反应相似（p>0.05）。1STST重复次数与6MWT距离密切相关（r = 0.809；p<0.001）。1STST重复次数≤13次的截断值被定义为与临床事件风险增加相关的功能损害[敏感性：100%，特异性：84.6%；AUC：0.94；95%CI 0.82至0.98；p<0.001]。
1STST是一种可靠且有效的评估工具，在AF患者中产生的血流动力学反应与6MWT相当。考虑到其可行性和时间效率，医疗保健专业人员可以使用1STST而非6MWT测试来测量该患者群体在受限环境中的功能运动状态。
