Inclusion criteria

Inclusion criteria: Healthy young men who have been engaged in high-intensity aerobic exercise and can tolerate 28 minutes of moderate to vigorous aerobic exercise.

Exclusion criteria

Exclusion criteria: 1. A history of neuropsychiatric disorders such as epilepsy, major depression, or schizophrenia. 2. Habit of smoke. 3. Contraindication for head MRI examination. 4. A history of severe drug hypersensitivity. 5. A history of cardiovascular disease. 6. Current diagnosis of internal diseases such as chronic anemia or chronic renal failure. 7.

Secondary

MeasureTime frame
Respiratory variables (minute ventilation, partial pressure of arterial carbon dioxide), circulatory dynamics (heart rate, blood pressure), participants' exercise self-efficacy, personality traits, and perceived exertion during exercise
