Abstract: Objective: To assess the level of perception regarding exercise behavior and analyze its influencing factors in post-ICU patients. Methods: Using the convenience sampling method, post-ICU patients at a tertiary grade A general hospital in Tianjin were selected as study participants from May 1, 2023, to May 31, 2024. Data was collected using the General Information Questionnaire, the Exercise Benefits / Barriers Scale, the General Self-Efficacy Scale, and the Brief Fatigue Inventory. Results: The Exercise Benefits/Barriers Scale score among the 241 post-ICU patients was 111.52±27.61. Perception of exercise behavior was negatively correlated with fatigue (r=-0.272, P<0.001), and positively correlated with self-efficacy (r=0.879, P<0.001). Stepwise multiple linear regression analysis revealed that general self-efficacy, level of fatigue, age, educational level, marital status, participation in early rehabilitation during ICU stay, and physical activity level before ICU admission were significant factors influencing the perception of exercise behavior. Conclusion: The perceived level of exercise behavior of post-ICU patients needs to be improved. Early implementation of rehabilitative exercise, enhancement of self-efficacy, and obtaining spousal support can help alleviate patients' fear of physical activity and fully mobilize their exercise motivation, thereby contributing to an improved perception of exercise behavior.

摘要： 目的：评估 ICU 转出患者锻炼行为感知水平，并分析其影响因素。方法：采用便利抽样法，选取 2023 年 5 月 1 日至 2024 年 5 月 31 日于天津市某三级甲等综合医院 ICU 转出患者作为调查对象。采用一般资料调查表、锻炼益处及障碍量表、自我效能量表和简易疲乏量表进行调查。结果：241 例 ICU 转出患者锻炼益处及障碍量表得分为（111.52±27.61）分，锻炼行为感知与疲乏呈负相关（r=-0.272，P<0.001），与自我效能呈正相关（r=0.879，P<0.001）。多元线性逐步回归分析结果显示，一般自我效能、疲乏程度、年龄、文化程度、婚姻状况、ICU 期间是否参与早期康复、进入ICU 前体力活动情况是影响锻炼行为感知的因素。结论：ICU 转出患者锻炼行为感知水平有待提高，早期进行康复锻炼、提高自我效能，获取配偶支持，帮助患者降低对体力活动的恐惧，充分调动患者的运动积极性，有利于改善其对锻炼行为的感知。
