简要总结
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
详细描述
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.

研究组 & 干预措施
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
