Recently, poor cardiorespiratory fitness (CRF) has been postulated as an adverse health outcome related to poor sleep quality. However, studies investigating the relationship between CRF and a subjective sleep quality index are scarce. Thus, the current study aimed to investigate the association between CRF and the Pittsburgh Sleep Quality Index (PSQI) in apparently healthy people. The secondary aim was to investigate the association between reported physical activity (PA) and PSQI.
Thirty-three healthy male participants volunteered to participate. CRF (VO) was measured via cardiopulmonary exercise testing on a treadmill. A short form of the International Physical Activity Questionnaire (IPAQ) was used to measure PA, and PSQI was used for the sleep quality index.
There was no correlation between CRF and PSQI total score or any component of the PSQI. There was a significant inverse correlation between IPAQ and PSQI total score (r = -0.36, = 0.04). Categorical data analysis of the two questionnaires revealed that 42.4% of the participants who reported low physical activity also had poor sleep quality.
The current study showed no association between CRF and the subjective sleep quality index but demonstrated a moderate inverse association between reported PA and subjective sleep quality index. The findings suggest that the more reported PA, the better the overall sleep quality.
最近，心肺适能（CRF）较差被认为与睡眠质量差有关。然而，研究心肺适能与主观睡眠质量指数之间关系的研究很少。因此，本研究旨在调查心肺适能与匹兹堡睡眠质量指数（PSQI）在健康人群中的关系。次要目的是调查报告的体力活动（PA）与 PSQI 之间的关系。
33 名健康男性志愿者自愿参加。CRF（VO）通过跑步机上的心肺运动测试进行测量。国际体力活动问卷（IPAQ）的简短形式用于测量体力活动，PSQI 用于睡眠质量指数。
CRF 与 PSQI 总分或 PSQI 的任何组成部分均无相关性。IPAQ 与 PSQI 总分呈显著负相关（r=-0.36，p=0.04）。对两份问卷的分类数据分析显示，42.4%报告体力活动水平低的参与者也存在睡眠质量差的问题。
本研究表明 CRF 与主观睡眠质量指数之间无关联，但报告的体力活动与主观睡眠质量指数之间存在中度负相关。研究结果表明，报告的体力活动越多，整体睡眠质量越好。
