Circadian Rhythm and Cardiovascular Recovery After Submaximal Exercise
Relationship Between Cardiovascular Recovery After a Submaximal Exercise Test and Circadian Rhythm: A 6-Minute Walk Test-Based Study
This cross-sectional, observational, and analytical study aims to investigate the relationship between morningness-eveningness characteristics and cardiovascular recovery after a submaximal exercise test in healthy individuals aged 18-45 years. Circadian preference will be assessed using the Morningness-Eveningness Questionnaire, sleep quality will be assessed using the Pittsburgh Sleep Quality Index, and cardiovascular recovery will be evaluated following the 6-Minute Walk Test
연구 개요
상세 설명
The study will include healthy volunteers aged 18-45 years. After written informed consent is obtained, participants will complete a sociodemographic information form, the Morningness-Eveningness Questionnaire, and the Pittsburgh Sleep Quality Index. Resting heart rate, oxygen saturation, and Borg dyspnea/fatigue scores will then be recorded, followed by the 6-Minute Walk Test. Physiological measurements will be repeated immediately after the test and at the 1st, 3rd, and 5th minutes of recovery.
The planned sample size is at least 124 participants. This was calculated using G*Power 3.1.9.7 based on a medium effect size (r=0.30), a significance level of 5% (α=0.05), and 90% statistical power, with an additional 10% allowance for possible data loss or missing data. Data will be analyzed using descriptive statistics, normality analyses, appropriate parametric or non-parametric comparison tests, correlation analyses, and multivariable regression analyses, with statistical significance set at p<0.05.

Single Group
Healthy volunteers aged 18-45 years. Participants will complete a sociodemographic information form, the Morningness-Eveningness Questionnaire, and the Pittsburgh Sleep Quality Index. Resting heart rate, oxygen saturation, and Borg dyspnea/fatigue scores will be recorded, followed by the 6-Minute Walk Test. Physiological measurements will also be obtained immediately after the test and at the 1st, 3rd, and 5th minutes of recovery. No intervention will be administered |

Heart Rate Recovery After the 6-Minute Walk Test
기간: Baseline and up to 5 minutes post-exercise
|
Heart rate will be recorded at rest, immediately after the 6-Minute Walk Test, and at the 1st, 3rd, and 5th minutes of the recovery period to evaluate cardiovascular recovery following submaximal exercise. |
Baseline and up to 5 minutes post-exercise

Oxygen Saturation (SpO₂) During Post-Exercise Recovery
기간: Up to 5 minutes after the 6-Minute Walk Test
|
Oxygen saturation will be recorded at rest, immediately after the 6-Minute Walk Test, and at the 1st, 3rd, and 5th minutes of recovery. |
Up to 5 minutes after the 6-Minute Walk Test
|
|
Borg Dyspnea/Fatigue Score During Post-Exercise Recovery
기간: Baseline and up to 5 minutes post-exercise
|
Dyspnea and fatigue will be assessed using the Borg Dyspnea/Fatigue Scale at rest, immediately after the 6-Minute Walk Test, and at the 1st, 3rd, and 5th minutes of recovery. |
Baseline and up to 5 minutes post-exercise
|
|
Morningness-Eveningness Characteristics
기간: Baseline
|
The Morningness-Eveningness Questionnaire assesses individuals' preference for the timing of sleep and daily activities. Scores range from 16 to 86, with higher scores indicating a stronger morning preference and lower scores indicating a stronger evening preference, rather than better or worse outcomes. |
Baseline
|
|
Sleep Quality
기간: Baseline
|
Sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI), which evaluates sleep quality and disturbances over the past month. The global score ranges from 0 to 21, with higher scores indicating poorer sleep quality. |
