About this trial
This study will investigate whether various types of regular exercise can provide protective effects against metabolic abnormalities induced by sleep restriction. It will examine responses related to metabolic health, cognitive function, energy expenditure, subjective feelings, and human behaviors, including physical activity and energy intake.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Age between 20-45 years.
Body Mass Index (BMI) between 18.5-27 kg/m².
No sleep-related medical conditions and good sleep quality, defined as a Pittsburgh Sleep Quality Index (PSQI) score ≤ 5.
Usual bedtime between 22:00-01:00, wake-up time between 06:00-09:00, with an average sleep duration of 7 to 9 hours; chronotype classified as "definitely not evening type" (score ≥ 42 on the Morningness-Eveningness Questionnaire), and no changes in sleep patterns over the past 3 months.
Disqualifiers
Special diets (e.g., intermittent fasting, ketogenic diet)
Recent injuries or contraindications to intense exercise.

Treatment groups
Trial outcomes
Primary outcomes
Glycemic Control
Glucose responses during the 3-hour oral glucose tolerance test (OGTT)
Pulse wave velocity (PWV)
Pulse wave velocity assessments (i.e., meters per second) will be collected before and during the 3-hour oral glucose tolerance test (OGTT).
Cognitive function (Accuracy)
Accuracy (i.e., %) in computerized tests will be tested before and during the 3-hour oral glucose tolerance test (OGTT).
Cognitive function (Reaction time)
Reaction time (i.e., milliseconds) in computerized tests will be tested before and during the 3-hour oral glucose tolerance test (OGTT).
Secondary outcomes
Resting energy expenditure
Energy expenditure will be collected before and during the 3-hour oral glucose tolerance test (OGTT).
Carbohydrate oxidation
Carbohydrate oxidation will be collected before and during the 3-hour oral glucose tolerance test (OGTT).
Fat oxidation
Fat oxidation will be collected before and during the 3-hour oral glucose tolerance test (OGTT).
Heart rate variability
Heart rate variability will be collected before and during the 3-hour oral glucose tolerance test (OGTT).
