Abstract

This study aimed to observe the effect of cardiovascular response to body positioning after cardiopulmonary exercise testing in post covid individuals. Ninety post covid participants (age group 18-45) were assigned into four groups: standing, sitting, supine, and prone position. All participants were assessed cardiovascular response, VO2max baseline, post exercise in standing, sitting, supine and prone by using pulse oximeter, digital sphygmomanometer, polar heart rate and Borg scale. In SpO2, rate of perceived exertion (RPE), diastolic blood pressure, and heart rate, there was no significant difference between the groups at pre-exercise. However, a significant difference was observed at 1 min post-exercise and at 3 min post-exercise. As for systolic blood pressure, there was no significant difference between the groups at pre-exercise and at 1 min post-exercise, but a significant difference was noted at 3 min post-exercise. The findings of this study suggest that, when comparing standing, sitting, supine, and prone positions, the prone position exhibited faster recovery in terms of oxygen saturation and rate of perceived exertion, while the supine position showed quicker recovery in both systolic and diastolic blood pressure. Additionally, individuals with long-COVID symptoms were observed to have a lower VO2max.

长期慢性阻塞性肺病患者在进行亚极限运动测试后对身体定位的心血管反应

本研究旨在观察锥体后凸者在心肺运动测试后对体位的心血管反应的影响。研究人员将 90 名膀胱癌术后患者（年龄在 18-45 岁之间）分为四组：站立位、坐位、仰卧位和俯卧位。使用脉搏血氧仪、数字血压计、极性心率和博格量表对所有参与者的心血管反应、最大氧饱和度基线、站立、坐姿、仰卧和俯卧运动后进行评估。在运动前的 SpO2、感知用力率（RPE）、舒张压和心率方面，两组之间没有显著差异。但在运动后 1 分钟和 3 分钟时，观察到了明显的差异。至于收缩压，各组之间在运动前和运动后 1 分钟没有明显差异，但在运动后 3 分钟有明显差异。这项研究结果表明，在比较站立、坐姿、仰卧和俯卧姿势时，俯卧姿势在血氧饱和度和感觉用力率方面的恢复速度更快，而仰卧姿势在收缩压和舒张压方面的恢复速度更快。此外，还观察到有长期 COVID 症状的人的最大氧饱和度较低。

期刊介绍： ''Comparative Exercise Physiology'' is the only international peer-reviewed scientific journal specifically dealing with the latest research in exercise physiology across all animal species, including humans. The major objective of the journal is to use this comparative approach to better understand the physiological, nutritional, and biochemical parameters that determine levels of performance and athletic achievement. Core subjects include exercise physiology, biomechanics, gait (including the effect of riders in equestrian sport), nutrition and biochemistry, injury and rehabilitation, psychology and behaviour, and breeding and genetics. This comparative and integrative approach to exercise science ultimately highlights the similarities as well as the differences between humans, horses, dogs, and other athletic or non-athletic species during exercise. The result is a unique forum for new information that serves as a resource for all who want to understand the physiological challenges with exercise.
